Seasonal Care Calendar

Because what your plants need in January is very different from July.

Understanding the Seasons

Growing season: Spring through early fall

• Plants are actively growing
• They need more water, fertilizer, and light
• This is when you repot, propagate, and fertilize

Dormant season: Late fall through winter

• Growth slows or stops
• Plants need less water, no fertilizer
• This is when you prune, plan, and resist the urge to buy more plants

Spring (March-May)

What Plants Need

• Water: Increase frequency as growth resumes
• Fertilizer: Start feeding again every 2-4 weeks
• Light: Move plants closer to windows as days lengthen
• Humidity: Still okay, but start monitoring as temps rise

Tasks to Do

• [ ] Repot — if roots are circling or growing slowly
• [ ] Propagate — take cuttings now for best success
• [ ] Fertilize — start at half-strength, build up to full
• [ ] Clean leaves — wipe dust off for max light absorption
• [ ] Check for pests — spring wakes bugs up too
• [ ] Move plants — gradually acclimate to brighter spots
• [ ] Calculate feed amounts — use our Fertilizer Calculator for precise dilution

Plants That Love Spring

• Monsteras, pothos, philodendrons (tropicals waking up)
• Any plant that produced no new growth in winter
• Plants you plan to propagate

Summer (June-August)

What Plants Need

• Water: Most plants need more frequent watering now
• Fertilizer: Full feeding schedule (every 2-4 weeks)
• Light: Protect from scorching midday sun
• Humidity: Monitor — AC can dry air out fast

Tasks to Do

• [ ] Water regularly — check pots weekly, not just on schedule
• [ ] Fertilize — peak feeding season
• [ ] Rotate pots — even quarter-turns prevent leaning
• [ ] Prune — shape leggy growth, propagate cuttings
• [ ] Increase humidity — pebble trays, humidifier, or grouping
• [ ] Monitor for pests — summer is bug season

Plants That Thrive in Summer

• Succulents and cacti (peak growing season)
• Tropical foliage (monstera, pothos, philodendron)
• Any plant you moved outside (acclimated first!)

Warning: Heat Stress

If temps regularly hit 85°F+:

• Move plants away from hot windows
• Water more frequently (containers heat up)
• Skip fertilizing (stressed plants can't use it)
• Expect some leaf drop — it's temporary

Fall (September-November)

What Plants Need

• Water: Begin reducing frequency
• Fertilizer: Stop by late October (or earlier in cold climates)
• Light: Days shorten — move plants closer to windows if needed
• Humidity: Heaters come on — monitor for crispy tips

Tasks to Do

• [ ] Reduce watering — let soil dry more between waterings
• [ ] Stop fertilizing — let plants rest
• [ ] Prepare for heaters — increase humidity
• [ ] Bring plants inside — if you moved any outside
• [ ] Quarantine new plants — check for pests before introducing
• [ ] Clean up — remove dead leaves, tidy up

Plants That Need Fall Prep

• Any plant that was outside
• New purchases going into the collection
• Plants that dropped leaves during transition

The Quarantine Rule

Always quarantine new plants for 2-3 weeks before adding to your collection.

Check under leaves, in leaf joints, and in soil. Most pests hide there.

Winter (December-February)

What Plants Need

• Water: Significantly less — most only need water every 2-4 weeks
• Fertilizer: Not needed (plants aren't growing)
• Light: Low light season — accept slower growth
• Humidity: Heaters are running — increase humidity

Tasks to Do

• [ ] Water sparingly — check soil before watering
• [ ] No fertilizer — until spring growth resumes
• [ ] Increase humidity — pebble trays, humidifier, or grouping

• [ ] Keep away from drafts — cold windows, heater vents
• [ ] Clean leaves — dust reduces light capture in low-light months
• [ ] Rotate occasionally — prevent uneven growth toward light

Plants That Handle Winter Best

• Snake plants (basically unkillable)
• ZZ plants (dormant and fine with neglect)
• Succulents (need almost no water)

Winter Warning Signs

• Yellow leaves — usually overwatering (most common winter mistake)
• Leggy growth — not enough light, normal in winter
• Brown tips — low humidity from heaters
• Drooping — check soil — could be underwatered OR overwatered

The golden winter rule: When in doubt, don't water.

Quick Reference: Monthly Checklist

Signs You're On Track

The Most Common Mistakes by Season

Spring

• Mistake: Fertilizing too early
• Fix: Wait until you see active new growth

Summer

• Mistake: Ignoring heat stress
• Fix: Move plants from hot windows, water more

Fall

• Mistake: Keeping summer watering schedule
• Fix: Reduce water as temperatures drop

Winter

• Mistake: Overwatering because "it feels like time"
• Fix: Check soil first — most plants are fine waiting

The Bottom Line

Match your care to the season, and you'll avoid 80% of houseplant problems.

Key takeaways:

• Spring: Resume feeding, repot, propagate
• Summer: Water more, fertilize regularly, watch for pests
• Fall: Reduce water, stop feeding, bring plants inside
• Winter: Water minimally, no fertilizer, increase humidity
