What Temperatures Cause Philodendrons to Enter Dormancy: Understanding Plant Hibernation Cycles

Rate this post

Philodendrons are among the most popular houseplants, their lush foliage bringing a touch of the tropics into our homes. We often find ourselves focused on maintaining the perfect balance of water, light, and soil conditions, yet temperature is a pivotal factor that can dramatically affect a philodendron’s health and growth.

When the mercury dips too low or soars too high, we witness a dramatic change in our green friends; they begin to hibernate, so to speak, entering a state of dormancy to protect themselves from stress.

Philodendrons enter dormancy below 50°F. Leaves droop, growth slows

💥 Quick Answer

If the temperature falls below 55°F (13°C) or exceeds 85°F (29°C), philodendrons are likely to enter dormancy to conserve energy.

We’ve observed that our philodendron thrives when the thermostat is set between 75°F to 85°F (24°C to 29°C). However, once the environment strays from this cozy range, growth can slow or cease.

It’s as if the plant is saying, “Time for a break.”

Nighttime temperatures should rest slightly cooler, between 65°F to 70°F (18°C to 21°C), simulating the plant’s natural tropical habitat where evenings are cooler.

Keeping these temperatures consistent helps prevent the shock that can trigger dormancy—a period of minimal growth and reduced water needs.

Our philodendron pals might be resilient, but they’re not fans of the cold. To them, anything chillier than 55°F (13°C) is a cold shoulder they’d rather not encounter.

Optimal Temperature Ranges for Philodendron Health

To keep our philodendrons healthy and prevent them from going dormant, we need to maintain the right temperature range.

These tropical green buddies enjoy a cozy climate similar to their natural habitat, so let’s ensure we’re providing them just that.

Dealing with Cold Temperatures

❄️ Dealing with the Chill

Philodendrons can’t snuggle under a blanket like we do, so we must keep them away from temperatures below 55°F to avoid cold damage.

Frosty conditions and cold drafts are like kryptonite to them; they’ll pull the emergency brake and may go dormant to survive.

Keep them away from drafty windows and remember that our homes can get chilly at night, so maintaining a nighttime temperature above 65°F is key.

Effects of Warm Temperatures

🔥 Too Hot to Handle?

While philodendrons love to bask in warmth, there’s a fine line before it gets too toasty. A range of 75-85°F during the day is the sweet spot.

Beyond that, they may start to look sunburned with yellow or brownish leaves—a telltale sign that they need a breather from the heat.

They rely on us to keep their environment stable, as prolonged heat can cause dehydration and stress.

Water and Humidity Requirements

When caring for philodendrons, striking the right balance with water and humidity is crucial to avoid dormancy. Too little of either and we risk the plant’s health.

Proper Watering Techniques

🚰 Water Requirements

We should allow the top 1-2 inches of soil to dry out before [watering again](https://philodendroncare.com/how-often-should-philodendrons-be-watered/). Overwatering can lead to root rot, a sign we’ve been too generous. It’s better to err on the side of too dry than too wet.

Philodendrons prefer their soil to be moist but not soggy. Here’s how we get it right:

  1. Check the Soil: Before we pour, we check the topsoil. If it’s dry to an inch deep, it’s time for a drink.
  2. Measure Amount: We aim for about 1 cup (250 ml) of water, then wait for it to absorb before deciding if more is needed.
  3. Seasonal Adjustments: As seasons change, so do our plant’s needs. In winter, they drink less, so we cut back accordingly.
💥 Remember not to let water sit in the saucer, as this can also lead to overwatering complications.

Maintaining Humidity Levels

Philodendrons thrive in higher humidity, but when we can’t replicate the tropics at home, we get creative.

Method How We Do It
Humidifier We use a humidifier to boost moisture in the air, especially during dry winters or in arid climates. 🌬️
Tray with Pebbles Setting the pot on a tray filled with water and pebbles increases humidity through evaporation without soaking the roots. 💧
Misting A [light misting](https://philodendroncare.com/how-often-should-philodendrons-be-misted-to-maintain-proper-humidity/) gives our philodendron a humidity hug, but we’re careful not to overdo it to avoid leaf problems. 🌫️
Grouping Placing our houseplants together creates a microclimate with higher relative humidity. Companion plants, unite! 🌿

A golden rule of thumb: Philodendrons need humidity levels of around 60% to flourish, but we keep an eye out for all the leaves.

If tips brown, it’s a tell-tale sign that the air is too dry for our green friend’s taste.

We stay vigilant, because the right humidity not only prevents dormancy but also keeps those leaves glossy and stunning.

Philodendron Dormancy Triggers and Care

When temperatures drop, philodendrons can enter a dormant state. Recognizing the signs of dormancy is key to adjusting care, ensuring these tropical beauties remain healthy even when they’re taking a snooze.

Let’s dig into the specifics of dormancy triggers and how to maintain a thriving philodendron during the colder times.

Recognizing Dormancy Signs

Philodendrons will show clear signs when they’re entering dormancy. Common indicators include slowed growth, reduced water intake, and a pause in new foliage development.

It’s our cue to scale back on certain aspects of care, like watering frequency and fertilization. These changes mimic the plant’s natural response to shorter days and lower light conditions.

Winter Care and Maintenance

During winter, our philodendron care routine needs a bit of tailoring. With the thermostat dipping, it’s essential to:

  • Keep temperatures above 55°F to avoid cold stress.
  • Reduce watering since the plant [absorbs less moisture](https://philodendroncare.com/how-does-light-exposure-influence-water-needs-for-philodendrons/).
  • Avoid fertilizing, as the plant’s metabolism slows, it won’t need the extra nutrients.

Guard them against cold drafts and consider providing extra humidity if your home air is dry.

Impact of Light on Dormancy

🔆 Light Requirements

Light plays a pivotal role in plant dormancy. With shorter days, philodendrons get less natural light, signaling them to slow things down.

Our job is to ensure they’re still getting enough to stay healthy without encouraging active growth. Position them where they can receive [bright, indirect light](https://philodendroncare.com/how-should-light-exposure-be-adjusted-for-philodendrons-during-winter/), or consider using grow lights on cloudy days or in rooms with low light.
