Plot 205: Seed Potatoes, Onions & Shallots. Snow

Seed Potatoes, Onions & Shallots. Snow

Last night's snow partially demolished the brassica / fruit cage. Two of the uprights snapped at ground level. Alder doesn't seem to be as rot-proof as we'd been told.

Today we spent £28 at the allotment shop on seven varieties of seed potatoes and a lot of onion and shallot sets. We hope to become self-sufficient for onions and potatoes now that we have another half plot.

We got first early Foremost and Rocket, second early Charlotte, maincrop Pink Fir Apple, Maris Piper, Desiree and Cara: 16kg of seed potatoes in all- enough for around 20x 5m rows. We won't chit them just yet as the weather is very cold so they are in the shed but protected from frost.

We also bought 750g of Sturion onion sets (about 150) and 1.3kg shallots for planting later this month.

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.
