MOLD ON BEE BALM PLANT HOW TO

Some gardeners split and replant their bee balms every year. However, as they spread outwards the center of the clump tends to die out which is why I recommend digging up the plants, splitting them and replanting them every two or three years. But, because they are native plants, they are not usually described as invasive plants. Is bee balm invasive?Īll wild and garden bee balms grow strongly, especially when planted in good soil. This can work for a limited period, but sooner or later the deer’s curiosity will ensure that they find the plants you are trying to protect. Some gardeners have tried using bee balm as a barrier to protect deer favorites, relying on the smell of bee balm to encourage deer to move away and browse elsewhere.

However, all wild and garden bee balms have strongly aromatic foliage so deer will not eat them unless they are very very hungry – and this is rarely the case in summer when there are plenty of other more palatable plants for them to eat. Deer prefer to eat foliage, flowers and stems that have little or no taste. (Image credit: Alamy Stock Photos/James Mundy Nature’s Ark Photography/) Is bee balm deer-resistant? Clear away all the old growth at the end of the season, and rather than composting it, burn it or use a garden waste collection service. Rust shows as rust-colored spots usually on the undersides of the leaves. Rust is more difficult to prevent but picking off infected leaves at the first sign is usually helpful.

Rust is another disease that infects bee balm. Some varieties are flagged as resistant to mildew, but most resistant varieties are still likely to be infected to a limited extent and after a few years the mildew may overcome the resistance. Regular lifting, dividing and replanting is also helpful so the growth is never allowed to become too crowded. Rich, fertile soil types that encourage vigorous growth are also helpful as mildew is less likely to attack plants that are growing well. Mildew is most often a problem in dry summers, so keeping the roots damp helps prevent infection. The main problem that affects bee balm is mildew, a white fungal growth on the leaves which disfigures the plants and causes the foliage to drop off.
