Hi to one and all, need some help with growing cucumbers in a greenhouse please. Tried last year and used tomorite to feed both cukes and tomato's, toms were fine but cukes made penty of flowers but failed to produce any fruits. Is there a different liquid feed I can use this year to improve the yield. Many thanks in advance. Dave

    There's no delicate way to put this but human urine is a great feed for tomatoes and cucumbers. Just don't tell people you feed the fruit to. o:)
    A great library has something in it to offend everybody.

    I should probably add that it sounds like a pollination problem rather than a lack of nutrients. Can bees and bugs get into your greenhouse?

    What is the variety? F1 all female cukes do not need pollinating. Marketmore is an outdoor ridge variety and does need pollination. Cukes like a more humid atmosphere than tomatoes.

    What variety is it? F1 plants are all female and don't need male flowers.
    Other varieties may need the male flowers to form fruits.
    I grew cue's last year for the 1st time and done lots of reading.
    I gather that Tomorite is OK for cue's, but a better balance for them is ordinary Miracle Grow plant food.
    I used that every 10 days alongside seaweed extract every 10 days (so they get something every 5 days).
    I had a great harvest - getting 12 from my 1 plant on 1 day was the record. Typically there were 1 or 2 ready every day from mid-June

  • Many thanks for your replies, it is much appreciated. 'Wildbones' I informed her indoors about the urine thing and she was not amused. I have read that cukes need lots of Nitrogen and that Tomorite does not have enough. 'Fidgetbones' and 'Pete 8' I am trying grafted cucumbers this year, the names are Grafted Cucumber – ‘Kuper F1’  (full size) and Grafted Cucumber – ‘ baby Rocky’  (Mini). Pete 8 you mention Miracle Grow plant food is that the liquid one or the soluble that you mix with water??? was looking at them today and the soluble has a more Nitrogen than the liquid one so was going to try that. Will look for the seaweed Extract one as well. Once again thanks for taking the effort to reply.

    Hi Dave - It's the ordinary Miracle Grow - the soluble one - not the slow release granules. It was the additional nitrogen (compared with Tomorite) that suggested it was a better match for cue's.
    Any F1 cucumber will be all female, so no pollination worries.
    Not sure if Baby Rocky is F1, but I would imagine it is as Rocky is an F1 variety.
    I get maxicrop seaweed extract from amazon - it's good stuff.
    Best of luck

    Hey Pete just curious, when do you start feeding your cucumbers from when they start fruiting or before?

    Hi Chris
    Last year was my first with cucumbers and I used the same plan as with tomatoes - start feeding every 10ish days with soluble miracle grow soon as the 1st fruits start to set. I give seaweed extract every 10ish days too.
    My Cucino is in a 2L pot atm and will be transplanting it into a 22L pot in the next few days. A big jump in pot size, but it's soon filled. And with a big pot less chance of it drying out between waterings - they are very thirsty
