Your Garden In SEPTEMBER
YOUR GARDEN IN SEPTEMBER
There are lots of jobs to do in the garden this month, here are our top four:
Divide your herbaceous perennials. This will keep your plants healthy and vigorous year after year and multiply your stock.
Net ponds now before autumn leaf fall gets underway to reduce the amount of debris entering the water.
Clean out cold frames and greenhouses ahead of autumn sowing and growing.
Plant spring-flowering bulbs now, such as daffodils, crocus and hyacinths, for glorious colour next year.
In the vegetable garden
• Keep harvesting crops. If you have a glut of fruit and veg try freezing, drying, pickling, and storing so that you can benefit from them later on. For a little inspiration, check out our recipes page for ideas on what to make with your produce.
• Pinch out the tips of outdoor cordon tomato plants to concentrate the plant's energy into producing ripe fruits.
• Harvest sweetcorn. To test if it's ready, pinch a kernel - it will release a milky sap when ripe. If the kernels are starchy you've left it too late, if they're watery they need a little longer to ripen.
• Pull or cut off the foliage of maincrop potatoes at ground level three weeks before lifting them. This will prevent blight spores infecting the tubers as you lift them and help to firm the skins of the potatoes.
• Spread newly dug potatoes out to dry for a few hours before storing them in a cool, dark place. Store them in paper or hessian sacks, as this will allow the crop to breathe while it's in storage. Only store undamaged, disease-free tubers - one rotten potato can ruin your whole crop!
Looking after your lawn
• Create a new lawn from turf or seed - autumn weather is favourable for good lawn establishment.
• Raise the height of your mower blades as grass growth slows down.
• Carry out essential lawn maintenance to avoid waterlogging and compaction. Aerate your lawn with a garden fork, removing thatch from the surface with a rakeand repairing dead patches. Use a specialist lawn scarifier if you have a large area to cover.
• Apply a special lawn top-dressing after carrying out maintenance work. Follow the instructions on the packet carefully.
• Feed your lawn with an autumn fertiliser which is rich in potassium and low in nitrogen.
• Control lawn chafers or leatherjackets with a biological control (nematodes).
Other jobs about the garden
• Improve clay soil before it becomes too wet or frozen by incorporating organic matter and/or horticultural grit.
• Sow green manures such as mustard, clover and ryegrass on uncultivated areas to improve soil and keep weeds down over winter.
• Create compost bins in preparation for all the fallen leaves and dead plant material which you'll be collecting over the coming months. Autumn leaves make a great addition to compost bins and are ideal for making leaf mould.
• Burn diseased plant material or dispose of it in your household or green waste. Don't compost it as the spores may remain in the compost and reinfect your plants.
• Raise pots off the ground for the winter by using bricks or 'pot feet', to prevent waterlogging.
• Clear pond weeds and net your pond in anticipation of autumn leaf fall.
• Blitz perennial weeds - they are more vulnerable to weed killers in the autumn. Use a glyphosate-based formula to kill both the leaves and the roots.
• Install water butts to collect rain this autumn and winter. Rain water is great for watering ericaceous plants such as blueberries, rhododendrons and camellias.
