so, to stop cold?
yeah, i see... i wasn't familiar with this outside of cloche for frost.
if it isn't cold, then there is companion planting for insects and birds and rodents (mainly rodents) and there is windbreaks for wind
probably need to think about more integrated use of the space if either of those are inconvenient, it's summer so i can rule out cold and thus wind and insects are the bane, or what?
Often used for sun too
To stop cabbage moths from eating our brassicas!
