Title: Polytunnel in shade
Post by: Mark's Sussex Allotment on April 23, 2014, 19:54
Evening all,

My parents-in-law have just erected a polytunnel that is 25 foot long, but it only gets mottled sunshine throughout the day, and will be in shade for about 5-7 hours a day.

Are they likely to be able to grow anything. I have said no, but they are convinced they know best.

Lots of things will grow, but will probably be very leggy.

Leafy greens will probably be OK, but then you really don't need a polytunnel to grow them.

I'd agree with Totty that most of the stuff you would look to grow undercover - tomatoes, peppers, aubergines and the like - will get leggy and drawn through lack of sun.

Why did they site the polytunnel where they have wizzyfax?  Is it the only option or do they have a sunnier spot available? Might be worth moving it if they can or can they prune back whatever is shading the tunnel :)

My polytunnel is shaded by next door for some of the day and in full sunshine other times. I get a reasonable crop of tomatoes (2-3 kgs per plant) and cucumbers. Peppers don't seem to do as well and I get more lettuces than we can eat over the winter.

Any protected space is (almost) better than none  :D and the real problem I have is keeping the temperature down when the sun is on the tunnel (its up to 40C now with both ends open).

Unfortunately, it's the only place it could be situated.

I told them not to bother, but they wouldnt listen.

I'm just worried everything will ge too leggy, but hey ho, it's not my problem I guess.

Mottled sunshine at best and full shade for such a long period of the day is not ideal. 

It may prove a struggle to grow some of the more sun loving crops, but they will just have to try things and see what works  :)
