Why Your Plants “Pause” in Winter

September 25th, 2025

If you’ve ever wondered why your houseplants suddenly slow down, drop a few leaves, or just seem a little “meh” once the snow starts to fly in New Brunswick, you’re not alone. Every year, gardeners from beginners to experts worry that their plants are dying when in reality, they’re just taking a well-deserved rest.

 

This seasonal slowdown is called dormancy. Think of it as a nap: plants conserve their energy during the darker, colder months so they can burst back with fresh growth when spring arrives. For gardeners, the trick is knowing the difference between a plant that’s resting and a plant that’s in trouble—and learning how to care for them properly during this downtime.

 

Over the next few sections, we’ll explore what dormancy really means, how to recognize it, and how to give your plants exactly what they need to make it through a New Brunswick winter strong and healthy.

What is Plant Dormancy?

Dormancy is nature’s way of hitting the pause button. Instead of pushing out new leaves, flowers, or roots, plants enter a slower metabolic state where they conserve resources. Outdoors, this helps plants survive long winters. Indoors, even though your house is warm, shorter days and lower light levels trigger many plants to dial things back.

 

Here in New Brunswick, winters bring:

  • Short daylight hours: By December, we only get about 8 hours of light.
  • Lower sun intensity: Even south-facing windows can feel dim compared to summer.
  • Dry indoor air: Heating systems lower humidity, which stresses plants further.

All of these signals tell your houseplants it’s time to rest. For some, dormancy is mild—they just slow down growth. For others (like orchids or carnivorous plants), it’s dramatic—they may shed leaves, stop blooming, or look like they’ve given up entirely.

 

The key takeaway? Dormancy is not failure—it’s survival.

How to Recognize Dormancy vs. Decline

One of the most stressful parts of winter gardening is wondering: Is my plant just resting, or is it dying? The signs can look similar, but with a closer look, you can usually tell the difference.

 

🔎 Signs of Healthy Dormancy

Slowed or stopped growth – no new leaves or buds for weeks.

Leaf drop – especially with plants like fiddle-leaf figs or bougainvillea.

Colour change – leaves may look a little duller or lighter.

Roots & stems stay firm – even if leaves look tired.

These are normal and nothing to panic about. Your plant is conserving energy, not giving up.

 

⚠️ Signs of Decline or Stress

Mushy or blackened stems – often a sign of overwatering or rot.

Foul smell from soil – root rot is setting in.

Crispy, brittle leaves or stems – from extreme dryness or cold drafts.

Complete collapse of structure – when the plant can’t bounce back.

 

✅ Quick Dormancy Check

Scratch the stem lightly with your fingernail—green tissue underneath means it’s alive.

Check roots by gently loosening soil—white or pale roots are healthy, brown and mushy means trouble.

Observe the timing—if it’s winter, dormancy is far more likely than death.

 

👉 The rule of thumb: if the base of the plant and roots are firm, your plant is alive. Give it time, and it will rebound once spring light returns.

General Winter Care Tips During Dormancy

Even though your plants aren’t actively growing, they still need the right conditions to stay healthy through the winter. Think of it less as “maintenance gardening” and more like “plant babysitting”—keeping them comfortable until it’s time to grow again.

 

Watering

  • Cut back: Most plants need less water in winter. Wait until the top inch of soil is dry.
  • Watch for signs: Wrinkled leaves = thirsty. Mushy leaves = too much water.
  • Bottom watering: Letting pots soak up water from below helps prevent soggy soil.

Light

  • Move plants closer to sunny windows (south or west-facing are best in NB).
  • Rotate pots every couple of weeks so growth stays even.
  • Use LED grow lights if you notice pale leaves or spindly growth.

Temperature

  • Keep most houseplants between 18–22°C (65–72°F).
  • Avoid cold drafts from windows and doors.
  • Don’t place pots right above heat vents or next to radiators—plants dry out fast.

Humidity

NB winters are dry! Combat this by:

  • Grouping plants together
  • Using a humidifier
  • Placing plants on pebble trays with water

Mist sparingly—too much moisture can cause fungal issues.

 

Pruning & Repotting

  • Prune only dead or yellowed leaves. Save major pruning for spring.
  • Repotting can shock dormant plants—wait until active growth returns.

  • Moisture meter (optional but handy)
  • LED grow light (clip-on for small spaces)
  • Small humidifier
  • Pruning shears
  • Pebble tray + spray bottle

Dormancy Across Different Plant Types

Not all plants handle winter the same way. Some barely slow down, while others look like they’ve given up entirely. Here’s what you can expect from the most common categories of houseplants and how to care for each.

Tropicals & Foliage Plants

Examples: Monstera, Philodendron, Fiddle-leaf fig, Peace lily

 

What happens in dormancy: Growth slows down or stops; some may shed a few older leaves.

 

Care tips:

Keep soil slightly moist but never soggy.

Increase humidity to prevent brown leaf tips.

Clean leaves with a damp cloth to maximize light absorption.

 

Fiddle-leaf fig spotlight: These are infamous for leaf drop in winter. If the stems are firm, don’t panic—new leaves will emerge in spring.

Succulents & Cacti

Examples: Aloe, Jade plant, Desert cacti, Holiday cacti

 

What happens in dormancy: Desert succulents/cacti nearly stop growing. Holiday cactus may bloom, then rest.

 

Care tips:

Water sparingly—once every 3–4 weeks is often enough.

Bright light is critical; south-facing windows are best.

Resist the urge to fertilize until spring.

 

Common mistake: Treating succulents like tropicals—overwatering is the #1 killer in winter.

Orchids & Flowering Plants

Examples: Phalaenopsis orchids, African violets, Poinsettias

 

What happens in dormancy: After flowering, many orchids lose blooms and rest before sending up new spikes. Poinsettias often fade after the holidays.

 

Care tips:

Don’t toss your orchid after the blooms drop—it’s resting.

Cut the flower spike back above the second node.

Keep in bright but indirect light; water lightly.

 

Reblooming myth-buster: Orchids can rebloom indoors with patience, light, and the right routine.

Carnivorous Plants

Examples: Venus flytrap, Pitcher plants, Sundews

 

What happens in dormancy: Venus flytraps may die back to the soil; pitcher plants turn brown and dry. This is normal.

 

Care tips:

Many require a true cool dormancy (10°C / 50°F or cooler).

Water with distilled or rainwater only—tap water harms them.

Don’t feed them in winter. Let them rest.

 

Reassurance: Even if they look dead, the rhizomes are often still alive underground.

Specialty / Tricky Plants

Examples: Fiddle-leaf fig (extra detail), Peace lilies, Holiday plants

 

Fiddle-leaf fig: Loses leaves easily from stress, especially in low light. Consistency is key.

 

Peace lily: May droop more in dry air; increase humidity.

 

Holiday plants (poinsettias, amaryllis): After blooming, they need rest. With the right cycle, they can rebloom next year.

👉 The main lesson: Know your plant’s type. 

What looks like “death” for one variety may just be a normal dormancy pattern for another.

Common Mistakes to Avoid

Even the most experienced gardeners slip up during the winter months. Here are the pitfalls to watch for when your plants are resting:

Overwatering

The #1 winter killer. Dormant plants don’t drink much, and soggy soil leads to root rot.

 

Fix: Always check soil dryness before watering; better to dry than too wet.

Fertilizing in Dormancy

Plants can’t process fertilizer while resting. Overfeeding leads to salt buildup in the soil.

 

Fix: Hold off on fertilizer until you see active spring growth.

Panicking Over Leaf Drop

Some plants (fiddle-leaf figs, bougainvillea, poinsettias) naturally shed leaves in winter.

 

Fix: Don’t toss them out—check stems and roots before assuming the worst.

Ignoring Humidity

Heated homes in NB get extremely dry, leaving plants crispy.

 

Fix: Group plants, use pebble trays, or run a humidifier.

Moving Plants Around Too Much

Constantly shifting plants to “fix” them stresses them more.

 

Fix: Find the brightest, most stable spot possible and let them adapt.

👉 A little restraint goes a long way. Think of yourself less as a “fixer” in winter and more as a “caretaker.”

Tips to Help Plants Thrive Until Spring

Winter dormancy isn’t about “keeping plants alive at all costs”—it’s about supporting them until the light and warmth return. A few simple habits can make the difference between struggling plants and thriving ones come spring.

Create a Winter Routine

Pick one day a week to check all your plants.

Test soil moisture, look for pests, and rotate pots if needed.

Consistency is more important than frequent tinkering.

Keep the Air Comfortable

Aim for 40–50% humidity if possible.

Move plants away from radiators, wood stoves, and baseboards.

Practice “Gentle” Watering

Use room-temperature water.

Water less often but more evenly.

Drain excess water fully—never let pots sit in it.

Look Forward to Spring

Dormancy is temporary—plants are recharging.

Once days lengthen, you’ll see fresh leaves, new shoots, and flowers return.

Use winter as a time to learn your plants’ rhythms and observe them closely.

Maximize Every Drop of Light

Clean your windows regularly—dust can block precious winter sun.

Group plants near the brightest spots.

Supplement with a grow light if you notice pale or stretched growth.

👉 Pro tip: Keep a little plant journal. Note when leaves drop, when growth slows, and when it picks back up in spring. Over time, you’ll see each species’ natural rhythm—and feel more confident in your care.

When the snow piles high in New Brunswick and daylight fades, it’s natural to worry when your plants slow down, shed leaves, or stop blooming. But remember: dormancy isn’t failure—it’s a survival strategy.

By giving your plants patience, lighter watering, brighter light, and a touch of extra humidity, you’re helping them rest and recharge. Whether it’s a stubborn fiddle-leaf fig, a quiet orchid, or a Venus flytrap that looks like it’s vanished, each plant has its own rhythm—and with the right care, they’ll reward you with a burst of life when spring returns.

 

So this winter, don’t panic if things look a little sleepy. Embrace dormancy as part of the cycle of gardening. After all, it’s not the end—it’s just a pause before the next chapter of growth.
