If they are in bags they need extra water ESPECIALLY when in flower Mrs S
I heard somewhere that when the flowers appear you should then cut storks back to ground and let potatoes grow for a further 2 weeks before digging up - to give the potatoes extra growing power without having to put energies into the storks and flowers. Is this right? (hopefully this is a confused emotion and not anything else!)
It is the leaves that feed the tubers -so no you do not cut them off
OK, one less job to do!
@Julie J, with main crop potatoes the shaws/haulms/storks are sometimes cut off if blight is spotted. You wait the fortnight before you lift, to let the blight spores die off. With new potatoes if they are the size of a small egg; we have tatties for tea !
Kestrel can be left for 20 weeks if desired,at which time they will have produced some quite large Potatoes which are ideal for baking.
