Chunks of information

March 21, 2011 - The first day of spring. This year it also was the first day that felt like spring. In addition to a normal greenhouse, i like to work with a cold frame, so i built one of cheap materials. Cold frames are excellent for sowing seeds of plants that later are planted in the open, such as cabbage and salad. Cold frames also allow vegetables to be grown earlier in spring and later in autumn. The height of my cold frame is such that it can accommodate pepper plants. To start with, i planted a species of potatoes that grow very fast. Having them in a cold frame they are protected against frost and harvest will be three weeks earlier. By that time, the potatoes of last year won't taste very well anymore and are are depleted from vitamins.

A sun room, or greenhouse adjacent to the living house. This one is 10 x 20 feet and is kept above freezing temperatures with the heat of a wood furnace inside the house. Plants that cannot bear frost can winter here. It is also used to sow crops in pots starting in January, such as tomatoes, eggplants, sweet and hot peppers.
Greenhouse in winter. All these vegetables were sown or planted in November. They can withstand moderate freezing temperatures and will begin grow quicker when the first spring days arrive. Garlic, onions, corn salad, fava beans, peas, spinach.
A small cold frame. I built it in one day. Size: 3 x 4 m. Covered with UV proof plastic.
Greenhouse in the midst of summer. Visible plants: Tomato, Physalis peruviana
Lettuce can stand a little frost. Here lettuce is protected in a greenhouse with a sheet of plastic against frost. These plants survived several week of deep frost. Garlic in the background.
