Allotments 4 All

I have very limited garden growing area and what I have is somewhat shady but I have a big greenhouse, now I don't need tons of tomatoes, peppers etc so am thinking about using one side of my greenhouse for regular veggies. Problem is of course it is in full sun and under glass so it gets hot so would like any advice from you poly tunnel folks as to what I could grow in there during the summer heat. Not, peppers, tomatoes, eggplant, cukes or melons though as I know about those, but what about any of the brassicas, carrots , turnips or parsnips..does anyone have any ideas for me.

Think sub-division, create a diffused radiation barrier with net curtains.Increase ventilation , possibly by removing a glass pane or two. Paint on whitewash shading onto the glass. Ensure sufficient watering and pay attention to humidity.

I have found that I can grow better carrots and climbing French beans(Cobra) in my greenhouse.

The carrots are usually free from carrot fly.

Obviously they require manual watering but that is no big deal considering I would be watering other specifically greenhouse plants in any case.

I hope that helps,incidentally having read Ancells comments the beans can offer some screening subject to where you place them.

At least you can eat beans not sure if I could say the same for net curtains

Tee Gee, I have never grown beans in the greenhouse except for some dwarf one s a few years ago. If you grow tall ones how are you supporting them? I don't have border soil but I have side by side  2 foot wide x 4 foot long containers

If you've never seen spider mite on your plot you might be OK, but beans under cover are even more of a magnet for them than aubergines (though the smooth-leaved ?turkish? aubergines seem almost immune).

Misting spider mites does control them, but then you have to worry about wetting your tomatoes and inviting blight in...

A row of tomatoes (without beans or aubergines) might be just as good a shade under a dry cover and less prone to bugs.

Cheers.

I grow them as a catch crop because they are quite fast growing and early to mature.

Usually I get two crops a season which allows me to crop fresh beans over a longer period.

As seen in the first picture they are planted out in rings in front of my sweet peppers then when the are cropped the peppers have more space to mature.

My second crop is usually put in after I have cropped something else and there is a space to put them in.e.g gap fillers, which is quite easy to do wnen you use rings or buckets.

Thanks Tee Gee, now I am pining for my UK Lottie and my 4 greenhouses.. boo hoo. Catch cropping is a great idea.

I have never seen spider mites here, I had them in my apartment once when I first came back to Canada, always baffled me as to how they managed to get to a 3rd floor window but they covered my trays of pepper seedlings which were destined to be sold at our community garden. I think they came in on an orchid  I had bought, boy where they a problem.
