Yucca plants are desert-like plants that grow in rocky and sandy locations and thrive in lots of sun rays. If you grow them indoors, they mightn’t receive as ample sunlight as they need. In this way, their leaves might curl like curry leaves.

When plants get insufficient light, the leaves will be darker than the usual leaves. And afterward, they will turn to curl.

Make sure the leaves are receiving the proper amount of sunlight. Yuccas need at least 8 hours of indirect, bright sunlight for their proper growth.

You can place them beside the window. If there isn’t ample light use plant grow light. But in case your room hasn’t enough sunlight, shift the plants to another good location.

2. Excessive Sunlight for Yucca Plant

Yuccas are fans of sunlight, but too much light may burn the leaves as well as curl up the edges of the leaves like olive trees. And even this may cause the death of the plants.

3. Infestation of Insect

Sap-feeding insects like aphids and thrips may invade yuccas when the plants are favorable for bugs. When these pests attack your yucca plants, the leaves will curl (like spinach) soon. They may also damage the roots and cut the leaves.

If the base of the plants is too messy or the space is very tight for which the plants can’t be exposed to the environment, in these conditions pests may be infested there as these places are ideal for pests living.

How to Treat It?

Always keep the plants clean. Isolate the infected plants. Prune the affected leaves to save other leaves. This will also help to grow new healthy leaves. And pesticides and neem oil are always good to use to stop pest attacks.

If you apply neem oil 2 to 3 times per week, this will prevent insect recurrence in the affected plants and they will get back to a healthier life soon.

4. Cold Damage of Yucca Plant Leaves

Yucca plants can survive in a wide range of temperatures. But they might be susceptible to damage in cold weather. If the plants are exposed to frost or cold weather for long, leaves will curl and damage.

If the temperature drops too much, you can cover the plants with a light blanket or transparent plastic sheet so plants get good protection against direct exposure to the cold or frost.
