Aloe is a tough plant, but indoor conditions can attract pests or cause rot. Most problems start with too much water, poor drainage or a new plant that brought pests with it. The good news is that early spotting and a few simple steps are often enough.
What to look for on the leaf
Tiny pale dots and fine webbing on the underside of a leaf suggest spider mites. A white cottony coating between leaves points to mealybugs. A sticky film on leaves and the floor is their honeydew. Soft, dark roots with an unpleasant smell signal rot from overly wet soil.
What to do
- Separate the affected plant from others straight away.
- Rinse the leaves with a stream of water and wipe off dust regularly.
- Remove dead and damaged parts and discard them.
- For rot, lift the plant, cut away black roots, let the cut dry and repot in fresh, free draining cactus mix.
- The pot must have drainage holes. Water only when the soil is completely dry.
- Use soap or horticultural oil only as a last resort, and only if the label says it is suitable for your plant.
Prevention
Keep a new plant apart for at least a month and inspect it. A badly infested plant is often easier to throw away than to treat. Do not use leaves with spots or signs of rot for food or skin care.
Once a month, check the undersides of the leaves and the bottom of the pot. If you move the plant into stronger sun, do it gradually over one to two weeks so the leaves do not scorch.
Common questions
Can I use a spotted leaf for gel?
No. Discard a leaf with signs of rot or mould and do not use it for food or on skin.
How often should aloe be watered?
Only when the soil is fully dry, in a pot with drainage holes. Overwatering is the most common cause of rot.
Before first use
Choose products for your dietary routine and care needs. Follow a healthcare professional’s advice for diagnosis and treatment of symptoms. Check suitability first during pregnancy and for use by children.
