Plot 205: Seed Potatoes and some pruning

Seed Potatoes and some pruning

Went to the allotment shop yesterday and bought nine kilos of seed potatoes for only £10.80.

Earlies: Arran Pilot - 3 rows
Main Crop: Pink Fir Apple - 3 Rows, Cara - 3 Rows, Pentland Javelin - 3 Rows.

Had a go at pruning the blackcurrants. Took off all the old wood with black bark at ground level, leaving some new shoots from last year. Still need to weed around them and lop some more of the tallest branches off the trees soon to get better fruit within easier reach.

The garlic and early onions are up and looking lovely and the spring cabbages are doing well. We're not so sure about the spring onions in the cold frame though.

There isn't much to eat at the moment; some sprouts and Jerusalem artichokes. There might still be the odd parsnip but it was too wet to dig. There is a row of celeriac beside the parsnips but it doesn't look like it's up to much. It went in way too late last year we think, but it's our second attempt at celeriac without success. The kale and and leeks are good to start eating in a week or so. They could maybe do with a feed of comfrey tea.

Our Crop Rotation

There are five beds in all.

One is a permanent bed for things like raspberries, currants, fruit trees, hops, strawberries, rhubarb and other perennials.

The other four beds have a simple rotation:

Year 1:

Potatoes. They are hungry plants so they like plenty of manure and compost. Later on, we plant out leeks in the space left after the early potatoes are harvested.

Year 2:

Peas, beans, onions and garlic. They like soil that has been previously manured. We plant a nitrogen fixing green manure such as Winter tares (vetch) once the onions and garlic are harvested.

Year 3:

Brassicas (including swedes) and sweetcorn. These like the nitrogen left in the ground by the previous crop. Lime is added in early Spring (or a sprinkling of crushed egg shells in the planting hole for cabbages). The brassicas need to be permanently netted because of the wood pigeons.

Year 4:

Roots such as carrots, parsnips and beetroot. These don't like rich soil.

Other things have to go in wherever we have space and we tend to grow things like tomatoes, herbs and salad at home.

Harvesting Calendar:

January The winter months are the time to enjoy root vegetables and stores of local fruit. Being harvested this month are leeks, green cabbages, parsnips, turnips, sprouts, celeriac, jerusalem artichokes, shallots, mushrooms and forced rhubarb. From store, apples and pears, beetroot and potatoes are available. Main crop carrots are either stored in the ground or kept in cold store to be available from September till the end of May. Onions are available most of the year.

February Winter root crops are still going strong. This is the month for early winter cauliflower, leeks, turnips, protected spinach, swede, celeriac, chard, forced rhubarb, and carrots. Potatoes, apples and pears are available from store. The sprout season comes to an end. Mushrooms are available most of the year.

March New crops of vegetables planted previous year come in to season, including purple sprouting broccoli, more cauliflower, spring greens, radishes, parsley, early rhubarb, and leeks. Carrots are available both from the ground and from store but beetroot from store is finishing. Potatoes, apples and pears are available from store.

April The stored crops start finishing in the middle of the month, but the new crops are not in full flow. Between mid-April and mid-June is the leanest time. But new season's lettuce and watercress come in, along with some overwintered spinach, radishes and purple sprouting broccoli. Rhubarb is in too. Carrots and potatoes are still available from store but apples and pears are finishing.
