What is bud blast?

michigoose(Z5OH)January 1, 2013

All of a sudden...you discover that your once plump buds have withered, yellowed and dropped off. This is bud blast, and it is heart breaking.

Bud blast is the withering and dropping of buds from an otherwise healthy plant. Generally, the culprit is a rapid change in environmentusually going from warm to cold and vice versa. In the winter, frequent causes of bud blast are drafts from windows, blasts from hot ovens, and bringing a plant in from the car or outside. In the summer, it can be rapid heat fluctuations In addition, some chemicals such as ethylene gas given off by ripening fruit can also cause bud blast, so it is best to keep budding orchids at least 10 feet away from ripening fruit.
