No matter how cool and gusty the September weather is, there are lots of useful tasks you can carry out in your garden. Whilst at this time of year it doesn’t feel like there’s much to do compared to other months, it’s the best time to survey the garden and split up surviving plants while adding more to the garden after seeing what is missing or dead.
With the soil being warm and due to the cool temperature of the atmosphere during the day, there’s very little need for watering. Instead time should be spent in getting the garden ready for the next set of flowering bulbs if it’s a flower garden or a bountiful harvest if it’s a vegetable garden.
September Gardening Tasks
- Arrange the order of your trees and shrubs; they would still grow because the soil is moist and warm. The hedges must be trimmed but only at the beginning of the month.
- As the weather cools, begin to split your herbaceous perennials. They can also be replanted and watered thoroughly.
- Collect seeds for perennials and plant, September is known for being a good time to plant such seeds because of the increased rainfall and the warmth of the soil. The faded blooms should be removed to extend the perennial performance.
- For vegetables, harvest them now before they are affected by the change of season, and store them for the winter.
- Pull out your main crop of potatoes, test to see if your sweet corns are ready by pinching them, and to produce ripe tomato fruits pinch off the plant’s cordon. Also help your pumpkins to ripen by removing shade leaves.
- Pick up blueberries, raspberries, strawberries, currant bushes, and blackberries as they ripen and use them or store their excesses by freezing. Check your plum, pear and apple trees for rotting fruits and have them picked before any disease spreads.
- Net your plants, so they don’t become meals for birds, and your ponds because of leaf falls. The long grasses under fruit trees should be mowed to spot wind fallen fruits easier.
- This time of the year is best for harvesting crops such as tomatoes, potatoes, celery, onions, apples, raspberries, and strawberries. They are also the best time to start planting autumn sets of onion, garlic, pumpkins, and sedum.
- Start the clean-up for autumn by clearing off old crops, flowers, and weeds to keep your garden clean and tidy.
- Start the planting of spring flowering bulbs and before that improve the soil by sowing green manure.
