Minimum Temperature: How Much Cold Can a Philodendron Tolerate?
Understanding a philodendron’s temperature limits is essential. Most varieties cannot tolerate temperatures below 13°C. In practice, when we talk about philodendrons and minimum temperatures, we can consider 13°C the critical threshold. Below this threshold, the plant experiences temperature shock, which causes its leaves to turn yellow or black and droop. The ideal growing temperature is between 18 and 25°C.
How to Monitor the Temperature on Your Terrace
1.Buy a digital thermometer: Choose an outdoor model with a memory function for recording minimum and maximum temperatures.
2.Choose its spot strategically: Place it in the shade, exactly where you’d like to put the plant.
3.Record the data for a week: Check the overnight minimum temperatures for at least seven consecutive days before moving the plant outdoors.
Where to Place a Philodendron Outdoors
Outdoors, place the philodendron in bright shade or partial shade, sheltered from the midday sun and wind. On a terrace or balcony, a north- or east-facing position is ideal. In the garden, it’s best to place it beneath the canopy of tall trees or under a pergola, which provide filtered light.
Choosing the right spot is crucial. Those looking for large-leaved outdoor plants like philodendrons usually want to create a tropical corner on their terrace, with large, decorative leaves.
Terrace or Balcony: The Ideal Spot
A north- or east-facing terrace or balcony is ideal. A philodendron on a terrace in bright shade grows better than in full sun, developing larger, deeper green leaves. The ideal spot for a philodendron on a terrace is in partial shade, sheltered from the midday sun.
Find the Perfect Spot on Your Terrace in 3 Steps
1.Sun map: Observe the sun's path throughout the day to identify areas with direct sunlight and those in shade.
2.Identify cool spots: Choose a corner that gets only morning light or is always in bright shade.
3.Wind test: On a windy day, feel which areas of your terrace are most sheltered.
Garden: Under Trees or Pergolas
In the garden, place the Philodendron under the canopy of tall trees or beneath a pergola. This will provide filtered light and natural protection.
Philodendron Outdoors: Spring and Summer
In spring, move the Philodendron outdoors when nighttime temperatures remain consistently above 15°C, acclimatizing it over about seven days from full shade to filtered morning light. In summer, it needs more frequent watering, whenever the top 3-4 cm of potting mix is dry, and fertilizing every two weeks.
When to Move the Philodendron Outdoors
The right time is when nighttime temperatures stabilize above 15°C. Gradual acclimatization is essential.
Acclimatization in 7 Days
1.Days 1-2: Move the plant outdoors for 2-3 hours in a fully shaded area.
2.Days 3-4: Increase exposure to 4-5 hours, always in the shade.
3.Days 5-6: Gradually introduce some filtered morning light.
4.Day 7: Place the plant in its permanent summer spot.
Summer Care for Philodendron Outdoors
Outdoors, watering needs to be more frequent. Check the soil daily, watering when the top 3-4 cm of potting mix is dry. Fertilize every two weeks.
Philodendron in Winter: Protection and Shelter
In winter, bring the Philodendron indoors when nighttime temperatures consistently drop below 15°C, because cold is its main enemy. If you can't bring it inside, protect the pot and foliage with bubble wrap, frost-protection fabric, or a frost blanket, reduce watering, stop fertilizing, and place it against a south-facing wall.
The topic of philodendron winter protection should be taken seriously, because cold is its main enemy.
When to Bring the Philodendron Indoors
When nighttime temperatures consistently drop below 15°C, it’s time to prepare to bring it indoors.
Winter Protection for Those Who Can’t Bring It Indoors
Protect the Philodendron from Frost in 5 Steps
1.Protect the pot: Wrap it in several layers of bubble wrap or nonwoven fabric.
2.Cover the foliage: Use a plant-specific frost-protection cover on the coldest nights.
3.Drastically reduce watering: Water only when the soil is completely dry.
4.Stop fertilizing: The plant is dormant.
5.Choose the right spot: Place the plant against a south-facing wall.
