The maincrop potatoes should be ready now.
You may well have reasonably sized parsnips now but they will stay perfectly happy in the ground and do taste better after they have had a frost on them.
The runner beans and French beans will be continuing to produce and the last of the peas should be coming in. Compost the foliage of the peas but leave the roots in the ground as the nodules on them contain nitrogen.
From the greenhouse you should be picking aubergines, chilli and sweet peppers as well as cucumbers and tomatoes.
If you grow fruit then the picking should be in full swing there as well:
Apples, pears, plums, peaches from the trees, blackberries and raspberries from the canes and strawberries from the bed.
Sowing, Planting and Cultivating
There’s not a great deal to sow now but surprisingly it’s the right time to sow winter lettuces.
The other salad crop is the winter hardy spring onion.
Your spring cabbage plants can be planted out now and over wintering (Japanese) onion sets can go in for an early onion harvest.
You can plant out garlic as well although I prefer to plant it out later in the year.
Keep feeding your tomatoes, peppers and cucumbers. It’s not really worthwhile feeding other plants at this time of year as they are nearly finished and the nutrients are best saved for the spring. Keep the side shoots in check on the tomatoes.
Tidy up the summer fruiting raspberries, cutting off the canes that have fruited and tying in the new shoots that will bear next year.
The summer fruiting strawberries can be attended to now as well. Cut off the foliage about 1″ from the ground, clearing and weeding as you go. Any runners can be planted up to replace 3 year old plants that are best replaced now.
Keep an eye on your brassicas for butterfly eggs and caterpillars, these will most probably be under the leaves.
