Philodendrons are tropical plants that have specific care requirements. If your plant hasn’t been correctly looked after, it will display symptoms such as wilting, curling leaves, and discoloring.
There are several reasons that the leaves of a Philodendron could be curling. This problem is most commonly caused by underwatering, low humidity, or incorrect temperature. Let’s look in more detail at why your Philodendron leaves are curling. We’ll also discuss what to do to solve your plant’s issues.
Philodendron Leaves are Curling, why?
Aim to get the watering requirements, light, temperature, and humidity right to grow a thriving philodendron. Here are some of the most common reasons that your plant’s leaves may be curling:
Philodendron Leaves are Curling, Why?: Underwatering
If your plant’s soil is parched and you can’t remember the last time you gave your philodendron a drink, underwatering is the cause of curling leaves. Be careful not to underwater your plant; stick to a consistent watering schedule. Before watering, you can check that the topsoil feels dry, but don’t let the soil completely dry out.
When the first 2 inches of soil feel dry, you can generously water your plant. Put your plant in the sink or bath when watering. Allow the water to seep through the drainage holes before you stop watering.
If you’ve underwatered your Philodendron and the soil feels dry, the leaves will be curled and will also feel limp. They may also have started to turn yellow or brown at the edges. Give your plant a thorough soak to revive it, and then regularly water your plant.
Water quality
If you’ve been watering your plant correctly and the soil doesn’t feel completely dry, the quality of your tap water may be to blame for curling foliage. Tap water contains chemicals such as chlorine and fluoride that can affect your plant. It also has minerals and salts, which over time will build up in the soil.
Some chemicals and salts cause the leaves to burn, making them curl up and turn brown at the edges. The best way to deal with this problem is to have a water filtration system installed in your home. Alternatively, collect rainwater for your plant or buy a jug that filters water. You can also leave some water in a mug overnight before watering your plant. This allows some of the chlorine to evaporate.
Temperature
Philodendrons are sensitive to the cold, and if left in a draft, the foliage may start to curl. Ensure your plant isn’t left beside an open window or near the air conditioning. Although Philodendrons are tropical plants, they shouldn’t be left beside heating vents. Hot air can dry out their leaves, lower the humidity and make your plant suffer.
Low humidity
As Philodendrons are tropical plants originating from the Brazilian rainforest, they like humidity of about 50 to 80%. These plants thrive in humid environments, and low humidity can dry out their leaves, causing them to feel dry. The leaves may look cracked or curled and turn brown.
The good news is that there are several effective ways to increase the humidity of your plant. One of the best things you can do is move your philodendron to the bathroom or kitchen. These rooms have slightly higher humidity than the rest of the home. Your Philodendron will enjoy the steam from a shower.
You can also increase the humidity around your tropical plants by investing in a humidifier. Alternatively, group tropical plants near each other and mist the foliage daily. Be careful not to soak the plants leaves as wet foliage is likely to rot. It’s best to mist your plant using a fine spray in the mornings. This will allow any excess water to evaporate throughout the day.
Another option is to use a pebble tray. Place a tray with water and stones underneath your philodendron. As the water evaporates, the plant’s leaves will get some moisture.
Philodendron Leaves are Curling, Why?:Final thoughts
As you can see, several things can cause a philodendron leaves to curl. Getting the basic care of your plant right will help improve its health. Ensure that you are watering your philodendron correctly, that it’s not in a draft and the temperature is kept cognisant and that the humidity isn’t too low.
