Aromatic plants are more resistant to diseases and pests than houseplants, but they can also be attacked by mold. If they were watered too often or if the pot soil had mold spores, they could also get sick.
Aromatic plants such as parsley, coriander, thyme or basil are not so demanding. They can be grown together in deep and wide pots on your kitchen’s window sill.
They are quite resistant plants, and their fragrance can keep away flies and mosquitoes. They must be grown in well ventilated and sunny areas. Without sun, they won’t have their strong flavor nor grow with rich foliage.
How does mold look like on aromatic plants?
Well, mold has the ability to attack the plants that grow close to each other where leaves don’t have space to dry out well after watering.
The mold appears as a dark grey to black powder on plant’s leaves. It spreads fast enough, and in less than a week can attack the whole plant.
The mold appears first on the leaves and the top of the young branches, but it also reaches the thicker and stronger stems quickly. Before attacking the entire plant, you should know what to do:
Saving aromatic plants
- Carefully cut all leaves or branches affected by mold. Gather the sick leaves and don’t let them rot near the healthy shrubs. Wash your hands with soap to remove all mold spores, and then dig the ground at the base of the plants, to be well ventilated, and spray some vinegar on it.
- Be careful not to touch the plants with vinegar unless it’s diluted with water in equal proportions.
- Cut the plants that have too many leaves and twigs, so that the air and sun to penetrate through the rich foliage and prevent the growth of mold.
Water plants more rarely
- Moisture is the main factor that favors mold. If your plants are already affected, water them rarely, once every 3 or 4 days and make sure you only water the soil and not the stems.
- Sometimes, when the mold is extended, it’s necessary to cut the entire plant. Some aromatic plants can be restored from the root if the plant is healthy and vigorous.
Watch out for chemicals!
- Aromatic herbs shouldn’t be sprayed with chemical solutions to combat mold, because you will harvest them and use them for food, so it’s best to avoid any chemicals. You can only use vinegar, but the best method is to cut the diseased plant.
