Himalayan Balsam

Quite a lot of publicity at the moment for a biological control of the above using the rust disease Puccinia komarovii. No one seems willing to discuss whether this disease will also destroy other members of the Impatiens family as they are of some significance to gardeners.

Not sure if it's of any significance but the above disease is related to a major disease of cereal crops.

I do wonder about the introduction of both plants and animals.

I can remember, as a student of Horticulture, many years ago admiring a planting in a large private garden of Japanese Knotweed.

Perhaps in a hundred years time someone will be asking what fool reintroduced Beavers!
