Planting cabbage, leek, potatoes

Depending on weather conditions, April is already suitable for planting vegetables such as cabbage, leek and potatoes. If you have not already brought on cabbage and leek yourself in the greenhouse (sowing then approximately from beginning/middle of February), you can obtain them from a gardener or gardening centre. Seed potatoes are also available there.

From the end of March/beginning of April, first place the seed potatoes in a cardboard box, which you then place in a light place at moderate room temperature to encourage the potatoes to sprout.

Place the pre-sprouted potatoes approximately five to ten centimetres deep in the loose soil, spacing 30 x 30 centimetres. After sprouting, when the seedlings are approximately one and a half hand-widths high, earth up the potatoes.

Plant the cabbage on a bed on which no cabbage or other cruciferous plants (such as red radishes or white radish) have previously stood. Add lime to the soil with 50 to 100 grammes of fertilising lime per square metre. Both measures serve to prevent the bacterial disease clubroot. The planting spacing of cabbage is approx. 50 to 60 centimetres, distance between rows also similar to the spacing in the row (cauliflower with 70 centimetres slightly further apart, broccoli, curly kale, Chinese cabbage, pak choi closer at 40-45 centimetres, the smaller varieties of kohlrabi around 30 centimetres). Plant the young cabbage plants a good centimetre deeper than the surface of the soil ball, as it then has more stability in the bed.

Also plant leek deeper, distance between rows 30 centimetres. The easiest way is as follows: loosen soil deep down, set plant twine and at the end of the rake handle make a mark “twelve centimetres”. Then along the plant twine, at intervals of 15 centimetres, make a vertical, twelve centimetre deep hole with the upturned rake handle. Then separate out the young leek plants from the seed tray, shorten the roots to two centimetres in length, also shorten the leaves so that they are still pointing upwards and not hanging over. Then place a leek plant in every plant hole – finished. You do not have to press them down.

When planting in early April, it may be useful to first cover the freshly planted seedlings with plant protection fleece. In areas with a greater risk of infestation by cabbage fly, carry out the complete cultivation period under a protective fleece – the same applies to leek and leek mining fly.

Tip: In the case of potatoes it is sufficient to plant them at the end of April or even at the beginning of May. An old farmer’s proverb says (approximately): “Plant the potato in April, it comes when it will. Plant it in May, it comes straight away”.
