Why are My Caladium Leaves Curling? Here’s What Could Be Causing It

It’s always disheartening to see your beautifully colored Caladium leaves curling up on themselves and dying off.

Fortunately, the problem could be something easy to fix and prevented from happening, so you can keep enjoying your Caladium plant.

If you’ve noticed that your Caladium leaves are curling up, it may be time to check the temperature and lighting in your home.

If the temperature drops below 70 degrees Fahrenheit or rises above 80 degrees Fahrenheit at night, or if the plant isn’t getting enough light, curling could be caused by those issues. You may also notice curling leaves if you’re overwatering or underwatering your Caladiums.

For more details, (why are my Caladium leaves curling), keep reading to find out what could be causing it.

Why are my Caladium Leaves Curling?

There are several possible reasons why your Caladium leaves are curling, and they include the plant not getting right the amount of water, the soil type (Soil pH), and lack the right temperature and light conditions.

Therefore, you should first see that the plant is getting enough water, the soil has enough nutrients, and it’s at the right temperature.

However, if the problem persists, here is a detailed guild to why your Caladium leaves are curling and how to fix it.

1. Watering Issues

Overwatering

Overwatering is a big problem for Caladium plants, particularly potted ones. Try watering your plant more frequently but less deeply, and make sure there’s plenty of drainage in your potting soil, or the roots will rot!

Ensure that each layer of soil drains properly so you don’t drown your poor plant. If your plant has been getting too much water, its root system has become waterlogged.

By repotting your plant into fresh soil with better drainage, you can solve this. However, if you repot too soon after over-watering, you may kill all of your roots instead—so wait until they have recovered before repotting!

Under-watering

One of the reasons you see Caladium plants curling up is because of drought. When your plants get the required measure of water they need for survival, they curl up to preserve water within their system.

When your Caladiums suffer underwatering for so long, you will see their stem bending, the leaves drooping, turning pale, then finally curl and die due to drought.

2. Too Much Sun

If you want to grow a successful caladium plant, knowing how much sunlight is ideal for them is important. Too much sunlight may end up burning and dying plants; too little light and they won’t grow at all or will only grow very slowly.

In general, they do best in partial shade. If you keep Caladiums in a place that gets full sun all day long, your plant probably isn’t going to do well there unless you move them indoors and provide additional lighting.

3. Wrong Temperature

Too cold or hot temperatures can cause your plant to curl, wilt, or lose its vibrant color and develop brown spots.

Caladium plants like warm temperatures between 70-85 degrees Fahrenheit (21-29 Celsius) with plenty of sunlight during daylight hours. However, they will tolerate temperatures up to 100 degrees Fahrenheit (38 Celsius) provided they have plenty of water and humidity; they’re tropical plants!

If you find out that your Caladium is curling or wilting in direct sunlight, consider moving it into a shadier area for better results. If you live in an area where nighttime temperatures dip below 60 degrees Fahrenheit (16 Celsius), consider investing in a grow light to keep your plant healthy.

4. Soil pH

If your potting soil is too acidic or alkaline, that can be a factor that is making your Caladium curling. Most Caladiums prefer a neutral to slightly acidic pH range (around 6).

Make sure you’re using an appropriately pH-balanced fertilizer for your plants, and check your soil’s pH level with a test kit (available at our home improvement stores) before planting.

5. Light Exposure

Exposing your plants to sunlight can cause leaf curl; to prevent leaf curl from occurring, keep them shaded for about one hour after sunrise and about one hour before sunset. In addition, make sure that your plant is getting enough water – but not too much!

6. Root Disease

Root diseases are another reasons why your Caladium leaves curl up. It doesn’t happen too often with caladiums, but they can get root rot if they don’t have enough water or stay too wet for long periods.

The symptoms include yellowing of leaves, leaf drops, and curling. If you think your plant might have a root disease, you should contact an expert to help diagnose it to treat it properly.

Other ways How to Fix Caladium Leaf Curl

Now that you know why your Caladium leaves are curling, here is a quick solution to fix it:

  1. Keep soil moist but not wet, and water only when needed.
  2. Give your plant some shade or rotate the position so sunlight doesn’t hit one particular spot every day.
  3. Maintain temperature between 60 and 80 degrees Fahrenheit (15 to 26 degrees Celsius).
  4. Adjust the pH in the soil that is too acidic or alkaline with an appropriate amendment like peat moss or ground lime.
  5. Watch for pests like aphids, mealybugs, and spider mites.
  6. If all else fails, ask your local nursery for advice on how to take care of your Caladium plant.

Frequently Asked Questions on Why Are My Caladium Leaves Curling

Why Is My Plant Leaves Curling in?

The three major reasons your plant is curling in include too much sunlight, not enough water, and root diseases. By taking away any one of these things, you should see your plant start to recover within days.

Curled leaves tend to grow back out as soon as you solve that problem, and then you’ll have a chance at growing a beautiful plant for yourself or your family!

Your plant may curl up its leaves to help protect itself from direct sunlight. If you don’t keep it watered well, your plant may also do this.

How Do You Fix Curling Leaves?

First, check to see if your plant is getting enough water by pulling a leaf out of the pot and gently bending it back and forth; if there’s no resistance and it feels limp, you should consider watering more frequently or using less porous soil to help retain moisture.

If that doesn’t solve the problem, try moving your plant to a shadier spot. If you still don’t see any improvement after making these changes, consult with an expert for advice.

How Often Should You Water Caladiums?

There’s a quick answer to that and a detailed one, depending on how you want to approach your plants’ watering schedule.

If you opt for shallow watering (i.e., only filling your pot halfway or so), they should get watered every 10–14 days in summer, when temperatures are high, and there is more sun; in winter, when temperatures and light levels drop, that can increase to every 7–10 days.

But if you prefer deep watering (i.e., filling your pot up until water comes out of its drainage holes), you may need to water only once per week during hot months and once every two weeks during cold months. Either way, check soil moisture with your finger before each watering—if it feels dry an inch below soil level, give them water.

How Do I Know If I’m Watering Too Much?

Look at your plant. Is it soggy or wilted? If so, you’re likely overwatering—the first thing to do is cut back on watering until things start looking better again. Then continue checking up on your plant regularly (every few days) to ensure that it isn’t getting too dry; adjust as needed.

How Do You Revive Dying Caladiums?

If you’ve got a plant that’s stopped producing flowers and is looking dead than alive, a good watering will revive it.

Just water your plant as normal and wait until new growth appears. If new growth doesn’t appear, try waiting a little longer before watering again, or take better care of your plants in the future to prevent another drought! Good luck!

Why is My Caladium Plant Drooping?

A caladium plant drooping is usually a sign of too much heat or direct sunlight on a plant during its growing stage, so moving your plant away from any direct light and providing more space between other plants and your Caladium should help restore its growth to normal.

Drooping can also occur when you have been given too much water, so only water your Caladium when it has dried out slightly in the soil. If you don’t see signs of life in several days, there may be another issue that requires fixing.

Final Word on Why are My Caladium Leaves Curling

Curling is a natural process when you let your plants stay in an environment that they’re not used to.

And because most of these plants are tropical, they’re not accustomed to cold weather and too much sunlight, making them curl up under extreme stress conditions such as these.

There are other factors at play here – temperature, light exposure, and type of soil you have – so don’t hesitate to keep on checking on your Caladium for signs!
