I planted my Cauliflowers today. I sowed them with the tomatoes back in March and now they are about 10cm high. Because we have a walled garden the temperature is a little higher inside than outside so it’s totally safe to plant out Cauliflowers.
I watched a show once where they suggested mixing lime with potting compost. The idea was to dig a big hole for each Cauliflower and put the lime mixture in the hole before planting. Lime helps combat Club Root which, if you have it in your soil, can ruin your chances of growing Cauliflowers or other Brassicas for a good few years to come. So needless to say I’m taking every precaution to avoid that.
Despite taking these precautions, Cauliflowers are still difficult to grow well. If the club root doesn’t get at them then the Cabbage White butterflies will, and if their caterpillars don’t munch through the whole lot then Cabbage Root fly will make the leaves wilt and die. The reality is that Cauliflowers will probably take up a lot of your time and attention – probably more time and attention than is really worth it if we’re being honest.
