Why have my aster plants suddenly collapsed?
Posted by Suttons Staff on 26 July 2013 01:08 PM
The reason for aster plants suddenly collapsing is most likely due to a disease known as Aster Wilt.   This is caused by a soil-borne fungus and plants are attacked after growing into promising specimens, frequently having reached the flowering stage. The leaves turn brown and hang down and a white mould can often be seen on the stems.  Affected plants should be removed and destroyed immediately.  Where an infection has occurred it is advisable to choose a fresh site for asters the following season. 

The disease is more likely to occur where asters are grown on the same ground year after year.  Changing sites of these plants as frequently as possible is the best method of avoiding trouble.
