7 Reasons Haworthia Turning White
Zebra plants are another name for Haworthias. They are Africans by origin. They naturally have white stripes on them. But when they are damaged or dying, they become white and soft. So, here are some of the reasons your Haworthia can turn white:
1. Sunburn
If you see your Haworthia turning white, check the amount of sunlight it is getting. Do you keep it outdoors under the sun for too long? Sunlight is good for plants. But succulents like Haworthia cannot tolerate direct sun heat for too long.
When the sunlight damages the tissues of Haworthia, it releases anthocyanin to ease sunburn. Too much secretion of anthocyanin causes the succulent to turn pale or white. Sunburned Haworthia cannot get back to their original color.
Thus, Haworthia should stay under a shade away from direct sunlight. It can be by a window or on a balcony where light and air can enter. You can put the plant outside under the sun in the morning, but not for more than an hour.
2. Powdery Mildew
Fungus can be dangerous for Haworthia. Powdery mildew is a kind of fungus that can turn your Haworthia white. When your Haworthia starts to show a whitish-yellow color, it is a sign that it is affected by powdery mildew. To be sure, check the stems of the succulent. They will turn brown because of the fungus.
Powdery mildew can slowly kill your plant. Fortunately, it is possible to get rid of the fungus. If you want to cure the fungus, naturally apply neem oil to your Haworthia.
3. Watering Problem
Sometimes, over caring for Haworthia can also be a problem. Over-watering Haworthia is a common reason it turns white. To check if your plant has an over-watering problem, check the leaves and stem. Are they getting soggy and the base getting white?
If so, then check the soil. It can be wet. These problems show your Haworthia is over-watered. To avoid this problem, water your Haworthia only when the soil is dry. You can save your overwatered Haworthia by carefully removing it from the pot and letting the roots dry in the open air. After the soil and the roots get dry, plant it back.
4. Pest Attack
Insects can attack any plant. They should be exterminated as soon as possible. Otherwise, they eat the plants. Mealybugs can be a severe problem for your Haworthia. They are white insects that feast on Haworthia.
When your Haworthia is severely affected by Mealybugs, they look white. These insects are dangerous not just for your Haworthia but also for other plants in your garden and house. They spread quickly and eat plants mercilessly.
Therefore, you must check the Haworthias from time to time for insects. You can use eco-friendly pesticides, alcohol, and neem to kill Mealybugs.
5. Poor Soil Quality
Your Haworthia may turn pale because of poor quality soil. They need soil full of essential nutrients. Without proper nutrition, the Haworthias will not grow, neither will they look good. Moreover, they will discolor.
Besides, the quality of soil is responsible for excessive moisture sometimes. The soil may hold the water too long, which will rot the roots of the Haworthia.
So, learn how to mix soil for your Haworthia. Experts advise mixing soil, perlite, and coco peat equally to create the soil for Haworthia. This mixture of soil has essential nutrients for Haworthia, and they let the water pass through to the pot’s drainage hole.
6. Problem With The Pot
Over-watering problems can also be caused because of the pot of your Haworthia. People who know little about plant pots put their succulents in a regular pot without a hole in the bottom. As a result, the excess water cannot pass. It causes the plant’s roots to rot, and eventually, the plant becomes soggy and pale.
So, choose a pot that has holes underneath the pot. The extra water will go through the soil and get out through the drainage hole of the pot. Thus, Haworthia stays healthy.
7. Seasonal Causes
Winter is coming, and suddenly, your Haworthia is looking whitish. But you do not have to worry because this color change is because of the season change.
Also, Haworthias change color and shade leaves during the growing season. Your Haworthia will eventually grow new leaves and look beautiful again soon.
How To Take Care Of Haworthia?
Getting a Haworthia for the first time? Then you should know how to take care of them properly. Haworthia is low-maintenance, but that does not mean you can leave them unattended for a long time.
To keep your Haworthia healthy, follow these rules:
Light Control
Haworthias are able to grow even in low and bright indirect light. So, you can keep them indoors. You can leave it outdoors for a while during the day.
But too much direct sunlight will turn the leaves yellow and damage them. When the sun gets really hot, take your Haworthia to a shaded area. Place them near a window where it does not get direct sunlight. The bright light near the window is enough for their healthy growth.
Sufficient Watering
Haworthia needs moderate watering. Over-watering or under-watering will kill them. Both can damage the roots of Haworthias. Therefore, you should only water your Haworthia when the soil is completely dry.
One way to check the dryness is to put your finger inside the soil and feel the moisture. If it feels dry, then water your succulents. Water the plant deeply but not frequently.
Do not spray water on the leaves because they will not absorb the water. Instead, the water will accumulate in blink spots and cause them to rot.
Choosing The Right Pot
No matter how careful you are about watering your Haworthia, the wrong pot can still cause damage to the root. You should get a pot that has a drainage hole.
When you water the Haworthia, the extra water should come out from the hole.
Place the pot in a well-ventilated area so that the soil gets dry. Also, the pot should be deep and spacious to let the roots of Haworthia grow freely.
Plant On Fertile Soil
You have to choose a good quality soil for your Haworthia. It should be gritty and able to drain the water fast. If you cannot find such soil, make the ideal mixture of gritty soil, perlite and coco.
Temperature
Haworthia needs an ideal temperature to grow and stay alive. You should not keep your Haworthia outdoors if the temperature gets below freezing point. So, you must keep it indoors all the time during winter.
Haworthia actually grows in cool weather. It goes dormant during the summer when the temperature goes above 80 degrees F.
