Weed tips
- If your lawn is beyond redemption, or in dire need of repair, now is the time to do it, while days are mild but there is enough warmth in the sun to promote rapid growth. If required, kill the existing lawn fully with Roundup. Wait for at least a week (until it is obvious the grass is dying) before cultivating and preparing the soil either for sowing seed or laying turf.
Garden maintenance in September
- Plant evergreen trees and shrubs, including hedges. Be sure to water regularly if the weather is dry
- Plant early potatoes
- Lift and divide overgrown clumps of perennials that weren’t lifted in autumn
- Clip lavenders after the first flush of flowers
- Start mowing the lawn regularly, and raise the cutting height to leave the grass a little longer – that will protect the roots from the sun
- Plant summer flowering bulbs – gladioli will bloom about 60 days after corms are planted
- Sow seeds of summer annuals like French and African marigolds, petunias and nicotianas
- Prune climbers and plant new ones
