Cucumber 'Adam F1' BIO

Cucumber 'Adam F1' is suitable for cultivation in a greenhouse, because the plants do not need pollination. Thanks to the firm and crunchy flesh, this cucumber is ideal for pickling. One bag is for approximately 5m2, and the planting distance is 150x40 cm.

Cucumber 'Adam F1' is an early, vigorous variety and develops beautiful smooth fruits of 7 to 10 cm. The plants do not need pollination, which makes them perfect for growing in a greenhouse. Due to the firm, crunchy flesh, these cucumbers are very suitable for pickling.

Fertilizing is recommended after the first flowering. Repeat this after three weeks and if necessary do this again when there are signs of nitrogen deficiency. Yellowing and bronze of the leaves can indicate potassium deficiency. If the fruits are regularly picked at a young stage, new cucumbers will continuously form. The harvest can then be extended over a longer period.

Saving seeds

Store seeds in a cool, dry and dark place, such as a sealed box in a cupboard. Pay attention to the expiration date on the packaging and use them before that time. If the packaging has been opened, make sure it is sealed properly and check the germination capacity before use.

You can easily test the germination capacity of seeds with a germination test :

  1. Place a few seeds (for example 10) on a damp piece of kitchen paper.
  2. Fold the paper towel closed and place it in a plastic bag or place it in a sealed container.
  3. Place it in a warm place, such as on the windowsill.
  4. After a few days, check to see if the seeds have started to germinate.
