Temperature stress is a popular cause of silver philodendron leaves curling and drooping. High temperature increases the rate of transpiration. The indoor plant roots will be unable to cope up with the rate of water loss and this result in wilting and curling of leaves.
The philodendron plant is adaptable to different conditions. But the houseplant will not survive under low and high temperatures. Subjecting the plant to temperatures below 55°F (12°C) will facilitate drooping and its death.
How to Fix
- Ensure the room receives bright indirect sunlight
- Keep the houseplant away from any source of heat
- Ensure the soil is moist during winter to prevent wilting
- Purchase a thermometer to help maintain 60-80°F (15-26°C) indoor temperature during the day
Watering stress is the primary cause of leaves curling, yellowing and drooping. The issue is quite prevalent since many growers do not know how to water their philodendron houseplant.

Damaged root system due to diseases inhibits intake of water from the soil. The plant will be unable to absorb adequate moisture and nutrients in the long run.
Philodendron plant will exhibit curling leaves and discoloration. Besides that, the potting soil will become smelly to indicate the presence of root rot.
How to Fix

- Inspect the root system thoroughly before repotting. Mushy roots imply that the philodendron plant cannot be revived.
- Learn to water the philodendron plant according to their schedule. We recommend checking the moisture content of the soil before watering.
Size of Pot
Philodendron is among the fast-growing houseplant. Some species grow between 3 to 8 feet and it is recommended to report the plant regularly.
Small pot usually makes the overgrown roots to experience a root-bound problem. The issue ends up inhibiting the proper intake of water and nutrients.
Larger pots will encourage overwatering and water may take longer to evaporate. The root-rot ends up destroying the houseplant.
How to Fix

- Ensure the new repotting container has drainage holes at the bottom
Type of Soil
Philodendron leaves curling and turning yellow could also be due to the soil type. The houseplant thrives in well-drained soil since there are minimal cases of waterlogging.
Permeable soil enhances root system aeration and intake of essential minerals and water. These nutrients foster better growth and healthy foliage.
Impermeable soil encourages waterlogging. The issue results in root-rot and this is responsible for the leave curling problem. Always check the type of soil before starting to consider growing the philodendron plant.
Philodendron plants are not resistant to any disease. The surroundings might make the indoor plant to contract the disease and leaves curling is one of the symptoms.

- Prune and discard the leaves infested by insects
- Spray the plant with a systemic insecticide to kill the insects
Lack of Nutrition
Lack of nutrients in the soil increases the pH level. The condition makes the root systems to absorb vital nutrients that support plant growth and healthy foliage.
Philodendron leaves curling can be caused by nitrogen deficiencies in the soil. The houseplant will be unable to undertake photosynthesis. The issue might also cause stunted growth and leave discoloration.
Phosphorus deficiencies cause also philodendron leaves to curl and turn yellow. The leaves might also experience the formation of brown spots.
How to Fix
- Ensure the soil pH is about 4.5-6.0. Get a pH tester from the market to help maintain a proper soil pH.
- Use compost to supply the plant with nutrients and moisture. It also helps to avoid the emergence of diseases.
- Fertilize philodendrons plants that exhibit stunted growth. We recommend urea or ammonium sulfate due to the presence of nitrogen and phosphorus.
Philodendron plants thrive under shade or areas that receive bright indirect sunlight. The light facilitates the breakdown of water during photosynthesis.
Too much light exposure cause dehydration of the plant. Philodendron plant experiences leave curling and drooping due to dehydration.
Keep in mind limited light exposure make philodendron plant to experience unhealthy foliage and leggy stems. This type of environment also causes stunted growth.

How to Fix
- Repot the plant if you have over-fertilized the pot
- Always apply fertilizer during the spring and autumn season
- Check the soil nutrients before applying fertilizer
- Use compost, bone meal emulsion, and manures instead of artificial fertilizers
Philodendron leaves curling could be due to low humidity, high temperature, lack of nutrients, lack of water, root-rot and light stress. Keep these factors checked will help to prevent philodendron leaves from curling and yellowing or browning.
