Is it ok to sow leeks now or am I too late? I'm thinking of sowing and bringing on in a polytunnel......whats your advice? I do already have some in the ground but wanted to have more as its one of our favourite veg.
The books suggest it is too late, but if you have seeds you don't lose much sowing in modules. A problem will be ensuring the soil remains moist for germination as summer comes on.
