Fall Preparation for Houseplants | FoliageFoundry

Understanding the Fall Transition

Fall represents a critical transition period for houseplants. As days shorten and temperatures cool, plants naturally begin shifting from active growth to a more restful state. Understanding this transition helps you provide appropriate care that respects your plants' natural cycles.

Natural Plant Responses to Fall

In their native habitats, most houseplants respond to fall's changing conditions in specific ways:

Growth slowdown: Most plants reduce their growth rate as light decreases
Energy reallocation: Focus shifts from new growth to strengthening existing structures
Leaf adjustments: Some plants drop older leaves to conserve energy
Root development: Many plants focus on root growth during this period
Dormancy preparation: Plants begin preparing for winter rest periods
Flowering changes: Some plants initiate flower buds for spring, while others finish blooming

These natural responses evolved to help plants survive the coming winter. Even in our climate-controlled homes, houseplants retain these seasonal rhythms to varying degrees. Working with these natural tendencies rather than fighting them leads to healthier plants year-round.

Why Fall Care Matters

Proper fall care serves several important purposes:

Stress Reduction

Helps plants gradually adjust to reduced light
Prevents shock from sudden environmental changes
Reduces susceptibility to pests and diseases
Prepares plants for winter's challenging conditions

Long-term Health

Respects plants' natural growth cycles
Allows necessary rest periods
Strengthens overall resilience
Sets the stage for robust spring growth

Practical Benefits

Reduces maintenance needs during winter
Prevents common winter problems before they start
Creates a smooth transition between care routines
Allows you to address any issues while plants are still relatively active

By implementing appropriate fall care strategies, you help your plants navigate this transitional season successfully and prepare them for the winter months ahead. The effort invested during fall pays dividends in healthier, more resilient plants throughout the year.

Light Adjustments

Fall's changing light conditions require thoughtful adjustments to ensure your plants receive adequate illumination as days shorten and sun angles lower.

Understanding Fall Light Changes

Several factors affect light availability during fall:

Reduced Daylight Hours

Days become progressively shorter
The reduction can be dramatic in northern regions
Less total light energy available to plants

Lower Sun Angle

Sun sits lower in the sky
Light must travel through more atmosphere
Reduced intensity even during sunny periods
Different windows receive light than during summer

Weather Changes

Increased cloudiness in many regions
More overcast days reduce overall light
Rain and fog further diminish light quality
Tree canopies may still block light until leaf drop

Indoor Factors

Heating systems activate, affecting plant locations
Window treatments may change for insulation
Home activities shift with the season, potentially affecting plant placement

Strategic Light Improvements

Implement these strategies to optimize fall light conditions:

Window Cleaning

Clean both inside and outside of windows
Remove summer dust and debris
Maximize light transmission
Consider professional cleaning for hard-to-reach windows

Plant Relocation

Move plants closer to windows
Prioritize south-facing windows (in northern hemisphere)
Consider east windows for gentle morning light
Avoid drafty locations near doors or windows

Obstacle Removal

Trim outdoor vegetation blocking windows
Remove summer window screens where possible
Adjust blinds and curtains to maximize daylight
Rearrange furniture that may cast shadows

Reflective Surfaces

Use light-colored walls to bounce light
Add mirrors to reflect light deeper into rooms
Consider white backdrop boards behind plants
Use light-colored trays under plants

Rotation Schedule

Implement a regular rotation system
Turn plants ¼ turn weekly for even exposure
Alternate plants between better and lesser light positions
Keep track of rotations with a simple calendar

Supplemental Lighting

As natural light diminishes, supplemental lighting becomes increasingly important:

When to Implement

Before plants show signs of light stress
As soon as you notice significantly shorter days
Typically by mid-fall in most regions
Earlier in northern locations or homes with limited natural light

Light Types and Placement

LED grow lights: Energy-efficient, full-spectrum options
Fluorescent fixtures: Affordable, effective for many houseplants
Position 12-18 inches above plants, adjusting based on intensity
Duration of 12-14 hours to supplement natural light

Light Scheduling

Use timers for consistency
Schedule lights during natural daylight hours when possible
Consider extending morning or evening hours slightly
Maintain a consistent day/night cycle

Light Intensity

Match intensity to plant needs
Increase gradually to prevent shock
Consider multiple light sources for larger collections
Layer lighting for different plant heights

By proactively addressing fall's changing light conditions, you help your plants maintain energy production during this transitional period. This preparation is especially important for light-loving plants that will struggle during winter's shorter days.

Watering Changes

Fall requires significant adjustments to watering routines as plants' water needs change with the season.

Reduced Water Requirements

Several factors contribute to decreased water needs during fall:

Physiological Changes

Slowed growth means less water consumption
Reduced transpiration (water loss through leaves)
Lower metabolic activity overall
Some plants enter pre-dormancy states

Environmental Factors

Lower temperatures reduce evaporation
Increased humidity in many regions
Reduced light intensity decreases water usage
Shorter days mean fewer hours of active water uptake

Pot Considerations

Soil stays moist longer between waterings
Evaporation from pot surfaces decreases
Root activity slows, reducing water uptake
Drainage may be affected by temperature changes

Watering Adjustment Strategies

Implement these approaches to adapt your watering routine:

Frequency Reduction

Gradually increase time between waterings
Allow soil to dry more deeply before watering again
Pay attention to individual plant needs rather than following a schedule
Expect to water approximately 25-50% less often than summer

Observation Techniques

Check soil moisture at depth, not just surface
Use a moisture meter for larger or more valuable plants
Lift pots to assess weight before watering
Watch for plant cues like slight leaf drooping

Watering Methods

Water thoroughly when you do water
Ensure complete soil saturation
Allow excess to drain completely
Consider bottom watering for more even moisture

Water Temperature

Use room temperature water
Avoid cold water that can shock roots
Allow tap water to sit overnight if possible
Consider collecting rainwater before winter

Plant-Specific Considerations

Different plant types require different fall watering approaches:

Succulents and Cacti

Reduce watering dramatically
Some may need water only once monthly
Watch for shriveling as a sign of needed water
Keep particularly dry during cool temperatures

Tropical Foliage Plants

Moderate watering reduction
Allow top 1-2 inches of soil to dry out
Maintain more consistent moisture for thin-leaved varieties
Watch humidity levels as heating systems activate

Flowering Plants

Research specific species requirements
Some need continued moisture to set buds
Others benefit from a dry rest period
Adjust based on flowering cycle

Plants with Special Structures

Plants with pseudobulbs (orchids) often need drier conditions
Plants with rhizomes may need less frequent but deeper watering
Thick-rooted plants can often go longer between waterings
Thin-rooted plants may still need more consistent moisture

Potential Watering Problems

Be alert for these common fall watering issues:

Overwatering Risks

Increased risk as soil dries more slowly
Can lead to root rot and fungal problems
Watch for yellowing leaves and soggy soil
Particularly dangerous as plant metabolism slows

Underwatering Signs

Crispy leaf edges
Slow recovery when water is provided
Leaf drop beyond normal seasonal shedding
Soil pulling away from pot edges

Humidity Challenges

Heating systems reduce ambient humidity
Consider humidifiers or grouping plants
Misting provides temporary relief at best
Watch for brown leaf tips indicating low humidity

By thoughtfully adjusting your watering routine during fall, you help your plants transition smoothly into their winter state. This adaptation is one of the most important aspects of fall care, as improper watering during this period can lead to problems that persist throughout winter.

Temperature Considerations

Fall's fluctuating temperatures present unique challenges for houseplants. Managing these changes helps prevent stress and prepares plants for winter conditions.

Understanding Temperature Changes

Fall temperatures affect plants in several important ways:

Outdoor Temperature Fluctuations

Wider day/night temperature swings
Sudden cold snaps possible
Gradual cooling trend overall
Microclimates around the home become more pronounced

Indoor Temperature Effects

Heating systems activate, creating dry heat
Drafts from doors and windows become more noticeable
Cold window surfaces can chill nearby plants
Temperature variations between rooms increase

Plant Responses to Cooling

Metabolism slows with cooler temperatures
Growth patterns change or pause
Cold damage can occur with sudden drops
Some plants benefit from cooler night temperatures

Optimal Temperature Ranges

Different plant types have different temperature preferences during fall:

Tropical Plants (majority of houseplants)

Daytime: 65-75°F (18-24°C)
Nighttime: No lower than 55-60°F (13-15°C)
Avoid exposure to temperatures below 50°F (10°C)
Examples: Philodendrons, Pothos, Monsteras, Calatheas

Cool-Tolerant Plants

Daytime: 60-70°F (15-21°C)
Nighttime: Can tolerate down to 45-50°F (7-10°C)
May benefit from cooler night temperatures
Examples: Cyclamen, Azaleas, Citrus, some Orchids

Temperature-Sensitive Plants

Maintain more consistent temperatures
Avoid locations with temperature fluctuations
Keep away from drafts and heat sources
Examples: African Violets, Begonias, Marantas

Temperature Management Strategies

Implement these approaches to create appropriate temperature conditions:

Home Zoning

Identify naturally warmer and cooler areas of your home
Group plants with similar temperature needs
Use cooler rooms for plants that benefit from temperature drops
Reserve the most stable environments for sensitive specimens

Window Insulation

Apply window film to create insulation
Use bubble wrap on windows for extra protection
Consider moving plants away from windows at night
Close curtains or blinds during the coldest hours

Draft Protection

Identify and seal sources of cold drafts
Keep plants away from exterior doors
Watch for drafts from air vents or fans
Create barriers with furniture or screens if needed

Heat Source Management

Keep plants away from radiators and heating vents
Avoid placing plants above electronic devices that generate heat
Consider the effects of fireplaces and space heaters
Monitor plants on windowsills above radiators

Temperature Monitoring

Use a min/max thermometer to track temperature fluctuations
Pay special attention to nighttime lows
Check temperatures at plant level, not just room temperature
Consider a smart temperature sensor for valuable collections

Special Temperature Situations

Some situations require extra temperature attention during fall:

Cold Windows and Windowsills

Window surfaces can be significantly colder than room air
Create insulation between pots and cold surfaces
Use pot feet, cork mats, or styrofoam to elevate plants
Consider temporary relocation during extreme cold

Sunroom and Enclosed Porch Plants

These spaces experience more extreme temperature fluctuations
Consider relocating sensitive plants to more stable environments
Provide extra insulation for plants that must remain
Monitor closely during the first cold spells

Dormancy Requirements

Some plants benefit from or require cooler temperatures to trigger dormancy
Research specific needs for flowering bulbs, cactus, and certain flowering plants
Provide appropriate cool periods for these species
Separate these plants from those requiring consistent warmth

By managing fall's temperature changes thoughtfully, you can prevent cold damage while also providing appropriate seasonal conditions for your specific plant collection. This temperature management becomes increasingly important as winter approaches.

Fertilizing Adjustments

Fall requires significant changes to fertilizing routines as plants' nutritional needs shift with reduced growth rates.

Understanding Fall Nutrient Needs

Plant nutritional requirements change during fall for several reasons:

Reduced Growth Rate

Less new tissue being produced
Lower overall metabolic activity
Reduced nutrient uptake capacity
Energy focus shifts from growth to maintenance

Root System Changes

Some plants focus on root development during fall
Different nutrient balance needed for root vs. foliage growth
Nutrient absorption efficiency may change
Soil microbiome activity often decreases

Preparation for Dormancy

Some plants store nutrients for spring growth
Others reduce nutrient uptake significantly
Excess nutrients can prevent proper dormancy
Nutrient needs vary by species and dormancy type

General Fertilizing Guidelines

Follow these principles for fall fertilization:

Gradual Reduction Approach

Begin reducing fertilizer strength by early fall
Dilute regular fertilizer to half-strength initially
Further reduce to quarter-strength by mid-fall
Discontinue most fertilizing by late fall

Timing Considerations

Last regular-strength feeding: 6-8 weeks before first expected frost
Final diluted feeding: 4 weeks before heating systems typically activate
Adjust timing based on your specific climate and home conditions
Consider plant-specific growth cycles when planning

Fertilizer Type Adjustments

Reduce nitrogen which promotes leafy growth
Consider lower-nitrogen, higher-phosphorus formulations
Avoid time-release fertilizers that continue releasing in winter
Consider organic options that release nutrients more slowly

Monitoring Plant Response

Watch for signs of excess fertilizer (leaf burn, rapid weak growth)
Note any unusual color changes in foliage
Observe growth rate changes
Be prepared to adjust your approach based on plant response

Plant-Specific Approaches

Different plant types have different fall fertilizing needs:

Plants Entering Dormancy

Examples: Amaryllis, Cyclamen, some Orchids, deciduous plants
Stop fertilizing completely as dormancy approaches
Follow species-specific recommendations for timing
Resume fertilizing only when new growth appears

Houseplants with Minimal Dormancy

Examples: Philodendrons, Pothos, Dracaenas, most common houseplants
Reduce fertilizer gradually through fall
May benefit from occasional very dilute feeding in winter
Resume normal fertilizing when days begin lengthening in late winter

Fall/Winter Flowering Plants

Examples: Christmas Cactus, Poinsettia, some Orchids
Research specific feeding requirements
Often need specialized fertilizer formulations
Timing is critical for proper bud development

Succulents and Cacti

Most benefit from fertilizer cessation in fall
Some growers provide one final low-nitrogen feeding
Resume feeding only when active growth is visible in spring
Watch for etiolation (stretching) which can indicate excess nitrogen

Special Fertilizing Situations

Some situations require special consideration:

Recently Repotted Plants

Plants repotted in late summer/early fall need minimal additional fertilizer
Fresh potting mix typically contains some nutrients
Focus on establishment rather than growth
Resume normal seasonal feeding in spring

Young or Actively Growing Plants

May need slightly longer fertilizing period
Reduce strength rather than stopping completely
Monitor for signs of leggy growth
Transition to winter care more gradually

Nutrient Deficiencies

Address any deficiencies before winter
Use targeted supplements rather than complete fertilizers
Document symptoms for reference
Recheck in spring when growth resumes

By adjusting your fertilizing routine appropriately during fall, you help your plants transition to their winter state without the stress of excess nutrients. This approach prevents weak, unseasonal growth and supports the plant's natural cycle.

Fall Pest Prevention

Fall is a critical time for pest management as indoor conditions change and outdoor plants come inside. Proactive prevention during this season can prevent major infestations during winter.

Understanding Fall Pest Dynamics

Several factors influence pest activity during fall:

Seasonal Pest Behavior

Many pests become more active before winter
Some pests seek indoor shelter as temperatures drop
Reproduction cycles may accelerate before winter
Pest resistance may increase in preparation for winter

Environmental Changes

Heating systems create drier conditions favorable to some pests
Reduced light can stress plants, making them more vulnerable
Closer grouping of plants facilitates pest spread
Outdoor-to-indoor transitions can introduce new pests

Plant Susceptibility Factors

Seasonal stress can weaken natural defenses
Growth slowdown affects plants' ability to recover from damage
Leaf drop may hide early signs of infestation
Dormant periods can mask ongoing pest activity

Comprehensive Inspection Routine

Implement this thorough inspection process:

Regular Systematic Checks

Establish a weekly inspection schedule
Examine each plant individually
Pay special attention to susceptible species
Document any findings for future reference

Inspection Focus Areas

Leaf undersides: Prime real estate for many pests
Stem joints: Hidden areas where pests congregate
Soil surface: Check for fungus gnats and soil-dwelling pests
New growth: Often targeted first by sap-sucking insects
Leaf axils: Where leaves join stems, perfect hiding spots
Pot rims and drainage holes: Entry points for many pests

Inspection Tools

Magnifying glass for spotting tiny pests
Flashlight for examining dark areas
White paper for tapping leaves to check for pests
Smartphone camera for documenting and zooming in
Plant journal for tracking observations

Preventive Treatments

Consider these preventive measures before problems develop:

Cleaning Treatments

Wipe down leaves with a soft, damp cloth
Shower plants to remove dust and potential pests
Use diluted soap solution (1 tsp mild soap per gallon of water) for monthly cleaning
Ensure plants dry adequately after washing, especially in cooler temperatures

Preventive Applications

Consider neem oil application before bringing outdoor plants inside
Apply insecticidal soap as preventive measure for high-risk plants
Use diatomaceous earth as a barrier on soil surface
Consider beneficial nematodes for soil-dwelling pest prevention

Environmental Controls

Maintain appropriate humidity (40-60%) to discourage spider mites
Ensure good air circulation without creating drafts
Use yellow sticky traps to monitor for flying pests
Keep leaf litter and debris cleaned up

High-Risk Situations

Pay special attention to these fall pest risk factors:

Outdoor-to-Indoor Transitions

Quarantine all outdoor plants for 2-3 weeks before joining indoor collection
Inspect thoroughly, including root systems if possible
Consider repotting with fresh soil to eliminate soil-dwelling pests
Treat preventively with insecticidal soap or neem oil

New Plant Acquisitions

Fall plant sales can introduce pests to your collection
Isolate all new plants regardless of source
Inspect carefully before purchasing if possible
Consider preventive treatments even if no pests are visible

Known Pest-Prone Plants

Some plants are particularly susceptible to certain pests
Examples include:
- Hibiscus (aphids, whiteflies)
- Citrus (scale, mealybugs)
- Ferns (spider mites in dry conditions)
- African violets (cyclamen mites)
Monitor these plants with extra vigilance

Common Fall Pests

Be particularly watchful for these common fall invaders:

Spider Mites

Thrive in dry conditions created by heating systems
Look for fine webbing and stippled leaves
Prevent with regular misting or humidity trays
Treat immediately if detected, as populations explode quickly

Fungus Gnats

Often appear as soil remains wet longer in cooler temperatures
Adults are annoying but larvae damage roots
Allow soil surface to dry completely between waterings
Consider sand or gravel top dressing to discourage egg-laying

Scale Insects

Often brought in on outdoor plants
Look for small bumps along stems and leaf undersides
Immature "crawlers" are most susceptible to treatment
Mature scales need physical removal and persistent treatment

Mealybugs

Commonly hide in leaf axils and protected areas
Look for white, cottony masses
Can spread quickly in closely grouped plants
Isolate affected plants immediately

By implementing these pest prevention strategies during fall, you create a strong defense against winter infestations when treatment is more difficult and plants are less resilient. This proactive approach is far more effective than reactive treatment once pests are established.

Bringing Outdoor Plants Inside

Transitioning plants from outdoor to indoor environments requires careful planning and execution to ensure their successful adaptation to indoor conditions.

Planning the Transition

Proper timing and preparation are essential for a smooth transition:

Timing Considerations

Begin transition before nighttime temperatures drop below 55°F (13°C) for most tropicals
Start the process 2-3 weeks before your region's first expected frost date
Bring in most sensitive plants first, hardier specimens later
Consider a gradual transition for plants that have been outdoors all summer

Space Preparation

Identify suitable indoor locations based on light requirements
Ensure adequate space for all returning plants
Consider light supplementation needs
Plan quarantine areas separate from existing houseplants

Priority Assessment

Evaluate which plants are worth bringing indoors
Consider size, condition, and pest risk
Some annuals may be better composted than overwintered
Focus efforts on valuable perennials and tropicals

Preparation Process

Follow these steps to prepare plants for the move indoors:

Pest Inspection and Treatment

Thoroughly inspect entire plant, including soil and pot bottom
Check leaf undersides, stem joints, and hidden areas
Treat any pest issues before bringing indoors
Consider preventive treatment even if no pests are visible

Cleaning and Grooming

Gently hose down foliage to remove dust and insects
Wipe leaves with damp cloth for extra cleaning
Prune damaged, diseased, or excessive growth
Remove any fallen leaves or debris from soil surface

Repotting Considerations

Consider repotting if:
- Plant is rootbound
- Soil quality has degraded
- Pest issues in soil are suspected
- Current pot is dirty or damaged
Use fresh, high-quality potting mix
Select appropriate pot size (usually same size or one size larger)
Ensure good drainage in new container

Acclimation Process

Begin by moving plants to shadier outdoor locations
Gradually reduce watering to indoor levels
Bring plants in overnight when temperatures cool
Return them outdoors during day for 1-2 weeks if possible
Finally transition to permanent indoor locations

Indoor Adjustment Period

Help plants adapt to their new indoor environment:

Light Adjustment

Expect some leaf drop as plants adjust to lower light
Position plants for maximum natural light initially
Consider supplemental lighting for high-light plants
Rotate plants regularly for even light exposure

Watering Changes

Reduce watering frequency compared to outdoor care
Allow soil to dry more between waterings
Check moisture levels frequently during transition
Watch for signs of overwatering as plants adjust

Environmental Factors

Monitor humidity levels around transitioning plants
Keep away from heating vents and cold drafts
Maintain stable temperatures during adjustment
Consider grouping plants to create humidity microclimates

Ongoing Monitoring

Watch for signs of stress during first 2-3 weeks
Check regularly for pests that might have been missed
Document any issues for future reference
Be prepared to adjust care based on plant response

Special Plant Categories

Different plant types require specific transition approaches:

Tropical Houseplants

Most sensitive to cold and should come in first
May need highest light levels indoors
Often benefit from humidity support
Examples: Hibiscus, Mandevilla, tropical ferns

Succulents and Cacti

Need gradual watering reduction before coming indoors
Require brightest possible indoor locations
Often benefit from grow lights during winter
May need very infrequent winter watering

Herbs and Edibles

Select healthiest specimens to bring indoors
Many benefit from significant pruning before transition
Often need very bright light to continue producing
May never perform as well indoors as outdoors

Bulbs and Tubers

Many benefit from dormancy period
Some can be stored dormant rather than grown indoors
Research specific species requirements
Examples: Cannas, Dahlias, Caladiums

By carefully managing the outdoor-to-indoor transition, you help plants adapt to indoor conditions with minimal stress. This thoughtful process significantly improves their chances of thriving through winter and returning to robust health when spring arrives.

Preparing for Dormancy

Many houseplants benefit from a period of winter rest. Fall is the time to begin preparing plants for this natural dormancy cycle.

Understanding Plant Dormancy

Dormancy is a natural survival strategy with several important characteristics:

Types of Dormancy

True dormancy: Complete growth cessation, often with leaf drop
Semi-dormancy: Significantly slowed growth without complete stoppage
Rest period: Reduced growth and metabolic activity
Growth suspension: Temporary pause in visible growth

Purpose of Dormancy

Conserves energy during unfavorable conditions
Allows plants to survive with minimal resources
Prepares for robust spring growth
Often necessary for proper flowering cycles
Strengthens overall plant health long-term

Dormancy Triggers

Shortened day length (primary signal for many plants)
Reduced light intensity
Temperature changes, particularly cooler nights
Reduced water availability
Natural hormone cycles

Identifying Dormancy Needs

Different plants have different dormancy requirements:

Plants Requiring True Dormancy

Many bulbs and corms (Amaryllis, Cyclamen)
Deciduous woody plants (Ficus carica, Hibiscus syriacus)
Some flowering perennials (Peonies if grown in containers)
Certain orchid varieties (Dendrobium nobile, Cymbidium)

Plants Benefiting from Rest Periods

Most common houseplants (Pothos, Philodendron, Dracaena)
Many succulents and cacti
Ferns and other woodland plants
Most flowering houseplants

Plants with Minimal Dormancy Needs

Some tropical plants from equatorial regions
Plants grown primarily for foliage
Specially bred varieties selected for continuous growth
Plants from regions without pronounced seasons

Research Resources

Reference books on specific plant species
University extension websites
Specialty plant society information
Observation of natural growth patterns

Dormancy Preparation Steps

Follow these guidelines to prepare plants for appropriate winter rest:

Light Adjustment

Allow plants to experience natural day length reduction
Avoid artificial light that extends day length for dormancy-requiring plants
Position plants where they can sense seasonal light changes
Consider moving some plants to cooler, lower-light locations

Water Reduction

Begin gradually reducing water as growth slows
Allow soil to dry more thoroughly between waterings
For true dormancy plants, follow species-specific watering protocols

Temperature Considerations

Research optimal dormancy temperatures for specific plants
Many dormant plants prefer cooler temperatures (45-55°F/7-13°C)
Some require specific temperature ranges to trigger proper dormancy
Consider creating cooler zones for dormancy-requiring plants

Fertilizer Cessation

Stop fertilizing plants entering dormancy
For semi-dormant plants, significantly reduce or eliminate fertilizer
Document when fertilizing was stopped for reference
Plan spring fertilizing schedule based on expected dormancy break

Special Dormancy Categories

Some plants have specific dormancy requirements:

Bulbs and Corms

Many require a dry rest period
Some need cool temperatures during dormancy
Follow species-specific protocols for:
- Amaryllis
- Cyclamen

Dormancy Monitoring

Keep track of plants during their rest period:

Minimal Maintenance Schedule

Check dormant plants periodically for:
- Signs of pests
- Mold or rot
- Excessive drying
- Unexpected growth
Provide minimal water as needed based on species
Maintain appropriate environmental conditions

Documentation

Record dormancy start dates
Note any special treatments provided
Document location changes
Plan spring care based on expected dormancy duration

Problem Indicators

Rotting or mushy stems or bulbs
Mold on soil surface
Pest activity during dormancy
Premature sprouting

By respecting and supporting your plants' natural dormancy needs during fall, you set the stage for healthier growth cycles and potentially better flowering in the coming year. This alignment with natural rhythms is an important aspect of sustainable plant care.
