Jobs for September
Posted: Friday 11th September 2026
General gardening jobs:
• In the greenhouse: continue to open the door/ windows on warm days and spray the floor with water to ensure a damp atmosphere to deter whitefly. Continue feeding Tomatoes *) Peppers, Chillies and Melons with Tomato feed – always follow the instructions on the bottle.
• If colder weather is forecast in the next few weeks, consider lifting tender plants e.g. Geraniums/ Osteospermums – plant up and move the pots into a greenhouse/ somewhere cool but well-lit indoors to be kept for next year.
• Continue to dead head bedding plants in pots/ borders regularly to keep them flowering but let a few go to seed (*)
• Continue to keep on top of the weeding in the borders by hoeing/ hand weeding and continue to watch for pest damage and disease.
• Most lawns have suffered from the drought but are beginning to re-grow. When mowing set the blades higher than would usually do and apply an autumn feed – preferably before rain is expected.
• As necessary, water pots/ hanging basket, veg and anything recently planted in the borders when the compost/ soil is dry.
• Give hedges a trim from now on to ensure they look good during the winter months. Watch out for any birds that have nested late because of the warm summer.
• (*) Collect seed heads/ seeds from annuals and store in paper bags for sowing next year.
• Take photographs of your borders to see what’s in flower and for a chance to look at what grew well and how to improve it next year.
• Start buying autumn flower plants and bulbs for pots and borders. Don’t plant tulips until early November to avoid Tulip blight.
