you can plant strawbs where ever you like, but if they are in pots you will need to water and feed more regularly. If in pots place them above trays of water(not in|) so as to avoid the Vine weevil.

i had 4 plants just in a plastic bag with water in out side 2 were for

a friend the other 2 still there and growing faster than the others in grow bags lololll

If planted in the ground its a good idea to put straw in and around the neck of the plants this in turn then keeps the fruits off the ground and avoids the fruits getting splshed with soil etc.

Thank you all for your help. I think I will keep them in the ground but make plenty of space around them for straw and netting to keep the birds off.
