Not everyone has a large garden, an allotment, a vegetable plot to grow vegetables.
That doesn’t mean you can’t still grow a few home-grown, fresh vegetables when you want them. If you have room for a pot, grow bag, or even a window box.of any size then there is nothing to stop you from having a go at growing your own.
If you have the dreaded club root as I do then don't be put off form growing cauliflowers. My caulis grown from seed from Simply Seeds have been the envy of the allotment for the past 2 years. Clapton shows no signs of clubroot. Miraculous.
