Same. I think I planted them too late last summer and now have gone to seed and virtually inedible. Planting more now.

Why have my leeks all gone hard and woody inside. They are beginning to flower but are still quite thin and woody

I have just lifted a fantastic crop of leeks. They grew so easily which I didn’t expect through the summer months but so happy they did. Would it be ok to replant leeks in the same soil for winter.
