Topical tips for September

It is not too late to cut back unruly wisteria, trimming off the wispy bits to 5 leaves, and tying in any branches to fill gaps.
Start taking cutting of tender plants such as salvias and penstemon, as insurance against the winter frosts.
Continue to trim hedges. Putting a sheet down first to catch the clippings will make clearing up a lot quicker.
Continue to pick runner beans etc. in the kitchen garden. It is not too late to sow quick crops of radish and lettuce.
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.
