Question About Cucumbers
What am I doing wrong? for 3 years now I've tried to grow cucumbers in my Polytunnel without success. I have tried the female 'telegraph' and the mini cucumbers. Both start to wilt at the stage they are getting their 3rd or 4th leaf, last year they went squishy at soil level and died, this year the new leaves are turning brown and crispy. They are in grow bags and not over or under watered, any suggestions please?

The major problem with poly tunnels is ventilation. I get a lot of condensation with mine as there's no vents in the roof. Seeds are prone to damp-off so this year I've placed them near a vent in the tunnel wall & had good success. I leave the door & 2 of the vents partly open permanently & this seems to have helped also.Llast year was my 1st year using a PT & all of my...

Sebs, here's some helpful information - http:// tinyurl .com/qb gcrr9
The real key to your problem is the opening statement of your post; "... What am I doing wronf. For 3 years..."
Thing is one shouldn't plant cucumbers in the same spot one year after another, nor should they be planted where tomatoes have been grown and vice-versa.
Cucumbers (and tomatoes) are subject to black spot and other fungii... quite susceptible. Try growing any variety of beans in that soil next year (they replace the depleted nitrogen for one thing). Next, plant you cucumbers somewhere they haven't been grown for at least one year... two is better... Sorry about this year, although, if it were here in the U.S. a greenhouse might have a nice, sturdy cucumber plant or two to try as suggested...

Clanad, thank you for your post but my cucumbers are planted inside the greenhouse and I can't move them around the garden as we are in the UK. Last two years they were in a small glass greenhouse and died, this year they are in a large polytunnel and are on the way out again. The tomatoes are thriving.

carrust thank you for that tip. My polytunnel has 'windows' in it at about waist height, about 12 in all which you can roll up to let in air. The fist morning I went in and it was like a turkish bath so one window is permanently open, even in this cold spell. Maybe I should open the window next to the cucumbers?
