Sowing

If you sowed onion seeds last month, these can be thinned, but take care not to disturb the remaining seedlings. Corn salad and dwarf early peas can be sown in a warm, sheltered border. Sow winter lettuces and other winter salad crops, like lamb’s lettuce: you may need cloches to protect these over the winter. Also, it’s the last chance to plant out cabbage seedlings this month: any plants not set out now should be left in the nursery bed over the winter.

As your plots are cleared you should also sow a green manure such as clover or rye grass to cover ground until next spring. Green manures will help prevent weeds establishing, and once dug into the ground the following spring they help return nutrients to the soil, helping the fertility of your plot.
