f1 cucumbers

can anyone give advice as what is best way to train these in the greenhouse please

 

Grow trailing types up supporting fences, nets, or canes, or allow them to climb up string. Nip out the growing point after 5 or 6 leaves have appeared and train the resulting stronger growths up the support, tying as needed.
when the shoots have reached the top of the support, nip them out 2 leaves beyond the flower; latterals will develope on which more fruits will form.
As fruiting continues, feed the plants every 2 weeks with a high potash fertiliser or equivalent organic liquid feed.
Regular watering is essential during the growing period, particularly after transplanting so that plants establish quickly, and during flowering and fruiting.
