The cucumbers can only be sown outdoors, when the soil temperatures are values of +10 Display up to 12 ° C.
This point in time is usually after 15. or 20. May reached. In cold soil, the seeds will not germinate and easily rot, which often requires reseeding. It is therefore better, wait until late May or early June. The time lag is made up for by faster emergence and rapid youth growth. Sowing after mid-June is not recommended. Pre-germinated seeds can be used for later sowings. Pre-germination is carried out in the same way as checking germination. The seeds are planted in the ground, when roots about 5mm long have developed, and lay them out at the right distance. This shortens the period between sowing and emergence by a few days.
Who has sufficient cultivation area, can also pre-cultivate the cucumbers in pots. In the first days of May one lays ever 2, best pre-germinated seeds, into small pots and put them in the cold frame. After the development of the second true leaf, but not before 20. May, can be planted.
