Cut down asparagus foliage

Harvest the last of the globe artichokes

Pick marrows, pumpkins and squashes – leave them to dry off and ripen before storing in a cool, dark place

Lift maincrop potatoes

Lift and dry onions

Sow a winter variety of lettuce

Plant garlic

Plant out spring cabbages sown last month

Earth up trench grown celery for the final time

Plant autumn onion sets
