9 Causes Of Yucca Plant Dying (Problems With Solutions)

Yucca plants, with their long trunks and narrow leaves, add a delightful tropical touch to any space, breaking the monotony of daily life. However, since they’re not suited for cold climates, growing them indoors can sometimes be tricky.

If a Yucca doesn’t get enough light, it might start looking weak and thin. Its leaves can droop, and if the issue isn’t fixed, they might die and fall off. Usually, moving the plant to a brighter spot can help it bounce back.

There are other issues that can harm your Yucca, like not watering it enough, diseases, pests, or using too much fertilizer.

1. Overwatering

Watering your Yucca regularly can sometimes lead to overwatering. When its roots sit in wet soil for too long, they can start to rot.

Symptoms:

  • The leaves might turn yellow and droop.
  • You may notice the base of the trunk looking discolored or feeling soft.
  • The plant could start wilting and dying.

Solution:

  1. Carefully take the Yucca out of its pot and clean the roots. If you find any rot, gently cut it away. Then, clean the cuts with hydrogen peroxide or a fungicide.
  2. Repot the plant in fresh, sterile soil that drains well. Make sure the pot has big holes at the bottom for drainage.
  3. To prevent root rot, wait to water the Yucca until the top 2 inches of soil in the pot are dry.

2. Underwatering

Underwatering

Not watering your Yucca enough is also a big problem. If it doesn’t get water on time, its leaves can lose their firmness, leading to drought stress. This could seriously risk the plant’s health.

Symptoms:

  • The leaves might become soft and start drooping.
  • They could turn pale or yellow.
  • You might see brown spots on the leaves.
  • The plant’s growth could stop.

Solution:

  1. Water the Yucca thoroughly, so the soil is moist but not waterlogged. Make sure any excess water drains out.
  2. Place the plant in partial shade for a few weeks.
  3. After that, water the Yucca when the soil is about 30-40% dry.

3. Temperature Stress

Yuccas love heat and can’t grow outdoors in cold weather. They do best in temperatures between 64°F (18°C) and 77°F (25°C). In this range, they usually thrive without many issues.

It’s important to keep the temperature above 50°F (10°C). If it falls below 45°F (7°C), the plant might get damaged.

Symptoms:

  • The leaves might become red and start drooping.
  • Leaves could turn yellow and die.

Solution:

  1. Move the Yucca to a warmer, more protected spot.
  2. Water it moderately. It should recover after some time.
  3. In the future, avoid taking the Yucca outside or onto a balcony when there’s a chance of a sudden drop in temperature.

4. Transplant shock

When you replant a Yucca, you might disturb its roots, leading to transplant shock. If the new conditions are very different from what it’s used to, the plant might struggle or even die.

Symptoms:

  • The Yucca stops growing.
  • Leaves turn pale, then yellow.
  • Leaves droop and the plant looks unhealthy.

Solution:

  1. After buying a Yucca, don’t rush to repot it. First, let it adjust by placing it in partial shade for a while.
  2. If it seems okay after 2 weeks, you can transplant it into a larger pot. This gives the roots more room and prevents tangling.
  3. Water the Yucca when the soil is about 30% dry. If there’s no improvement after a week, gradually increase the light to a level that’s comfortable for the plant.

5. Not Enough Light

Not enough sunlight

A common reason Yuccas die is not getting enough sunlight. They really love light and need as much of it as possible. But often, they’re mistakenly put in dark corners or at the back of a room.

Symptoms:

  • At first, the Yucca might grow more, but then its leaves will become brittle and start breaking.
  • The leaves may turn yellow and the plant can die.

Solution:

  1. Move the Yucca to a spot where it gets at least 4-6 hours of direct sunlight every day.
  2. Help the Yucca adjust to more sun by slowly increasing its sunlight exposure.

6. Diseases

Disease is another reason why Yucca plants might die, with fungal diseases and blight being quite common. These usually attack Yuccas that are already weakened from not being cared for properly.

Symptoms:

  • The leaves might develop spots, become necrotic (dead tissue), and wilt.
  • You could see brown spots on the leaves.
  • The leaves might droop and turn yellow.

Solution:

  1. Spray the affected plant with a fungicide, and repeat if needed.
  2. Ensure good air circulation around the plant.
  3. Water the plant just the right amount, not too much.
  4. Make sure the Yucca gets enough sunlight.

7. Pest Infestation

Yucca plants can be attacked by two main types of pests. The first includes insects like aphids, mealybugs, and scale. These pests feed on the plant’s sap by sucking on the leaves and petioles.

The second type is spider mites, tiny white or reddish-white creatures that create thin webs. They, too, feed on the plant’s sap.

Symptoms:

  • The leaves start turning yellow.
  • There are small brown spots on the leaves.
  • You might see a white substance on the leaves.

Solution:

  1. The most effective initial treatment is spraying the plant with horticultural oil.
  2. If the pests persist, using an insecticidal soap may be necessary.

8. Improper Fertilization

Using too much fertilizer can harm your Yucca plant, especially nitrogen-based fertilizers. Excessive nitrogen can cause rapid, weak growth in the leaves and stems, making the Yucca brittle and more prone to disease. Also, an overload of phosphorus and potassium can damage the roots, leading to droopy, yellow leaves, and potentially killing the plant.

Symptoms:

  • The Yucca grows quickly, but its leaves and stems are soft and fragile.
  • Leaves turn yellow and droop.
  • The plant becomes very prone to diseases.

Solution:

  1. Start by watering the Yucca heavily. Do this over a tray so excess water and some of the fertilizer can drain out.
  2. After a while, repot the Yucca in fresh soil.
  3. Limit fertilization to 2-3 times a year: once in early spring, again in late spring, and a final time in mid-summer.
  4. Don’t fertilize the Yucca in winter.

9. Sunburn

Too much sun can be deadly for a Yucca plant, especially when it’s moved outside in the summer after being indoors. Indoors, it gets only a little diffused sunlight, but outside, it suddenly faces direct sunlight all day, which can be too intense.

Symptoms:

  • The leaves, not used to direct sunlight, may start to burn, curl, and develop yellow or white spots.
  • In severe cases, the Yucca might lose all its leaves and die.

Solution:

  1. Slowly get the Yucca used to more sunlight. Move it to gradually brighter spots about once a week.
  2. Cut back on the number of hours in direct sun.

How do you revive a dying Yucca?

Reviving a dying Yucca involves a few key steps:

  1. Remove any rotten parts from the roots and replant the Yucca in fresh soil.
  2. Apply a multi-purpose fungicide to the leaves.
  3. Keep the plant away from cold drafts.
  4. Ensure good air circulation around the Yucca.
  5. Make sure it gets at least 6 hours of direct sunlight daily.
  6. Water the plant only when the top 30% of the soil in the pot has dried out.
  7. Treat and remove any pests that might be infesting the Yucca.

Will my Yucca leaves grow back?

If your Yucca’s stem and roots are still healthy, its leaves can grow back. The plant will start producing new leaves after a while, but this recovery process can take several months.

During this time, it’s important to take good care of your Yucca. Make sure you neither overwater nor underwater it. Also, initially reduce its sun exposure. As the plant begins to grow and recover, you can gradually increase the amount of sunlight it gets.

What does an overwatered Yucca look like?

An overwatered Yucca typically shows these signs:

  1. Leaves turning yellow.
  2. Soil in the pot is consistently wet.
  3. The base of the stem feels soft.
  4. Roots become mushy.
  5. Brown spots appear on the leaves.
  6. The leaves start to droop.
