While you may be hoping for an Indian summer, there’s still sowing, planting and tidying to be done before autumn winds arrive. The rewards are worth it, though: late flowers are still blooming, and plenty of fruits and vegetables are ready to harvest. Here’s how to make the most of your garden this month.
September is one of the busiest months in the gardening calendar. While you may be hoping for an Indian summer, there’s still sowing, planting and tidying to be done before autumn winds arrive. The rewards are worth it, though: late flowers are still blooming, and plenty of fruits and vegetables are ready to harvest. Here’s how to make the most of your garden this month.
It might feel early to think about next summer, but September is the ideal time to sow seeds for hardy annuals such as cornflowers, marigolds, love-in-a-mist and poppies. If you have favourite plants in your garden, collect their seeds now and store them in labelled envelopes ready for spring sowing.
Border plants and shrubs can suffer in cold winter weather, and it’s a good idea to protect their roots now to keep them healthy throughout autumn and winter. All you need to do is put down some mulch or bark to provide insulation. Just remember to scatter cat repellent to avoid any visitors from kicking up the chippings.
Border plants and shrubs can suffer in cold weather, so protect their roots before winter sets in. A layer of mulch or bark provides effective insulation. To stop cats from disturbing it, scatter a little repellent around the edges. Your lawn needs attention in September. At the very least, apply an autumn lawn feed so the grass can absorb nutrients before the frosts arrive. For best results, scarify the lawn with a rake or scarifier to remove moss and let light and air reach the roots — especially valuable as days grow shorter.Read our article: Back to gardening in September
Golden leaves may look beautiful, but left on the ground they can cause problems. They harbour fungal infections, block light from reaching the grass and rot in places you don’t want, such as ponds. Collect them instead and store in bin bags or a chicken-wire cage to make rich leaf mould compost.
For crops like pumpkins and squashes, cut back some of the foliage so the ripening fruits can soak up as much late sun as possible.
If you have apple or pear trees, gather ripened fruits before they fall and bruise. Check daily and store your harvest in a cool, dry place or fridge — stalk side down on trays helps prevent damage. Remove any spoilt fruit promptly to stop mould spreading.
September is also a good month to sow hardy greens such as kale, pak choi, lamb’s lettuce and mustard for winter harvests. You can also sow hardy peas and beans for an early crop next year. If you’re growing tomatoes, keep them sheltered and warm to encourage the last fruits to ripen.
