September Tasks

Continue to trim hedges. Putting a sheet down first to catch the clippings will make clearing up a lot quicker.
Dead heading the herbaceous borders will prolong the display, but if you want to save seed, don’t forget to leave some flowerheads uncut!
Keep cutting lawns, gradually raising the cut in preparation for winter.
Check fruit trees and remove any fruit affected by brown rot to reduce infection spread.
Be particularly careful when picking tree fruit as wasps love windfalls and can become quite drunk, presenting quite a hazard.
Continue to pick runner beans etc. in the kitchen garden. It is not too late to sow quick crops of radish and lettuce.
If your greenhouse cucumbers are suffering from an attack of red spider mite, try putting a block of wet straw by the plants to increase humidity.
