Cauliflower ready for harvest.

Cauliflower prefers cool weather to grow. Plant in the early spring for summer or early fall harvest and early summer for late fall harvesting. These vegetables are best transplanted as they get more growth before the heat of summer.

Some gardeners feel this is a difficult vegetable to grow.  It grows in similar conditions as Broccoli or Cabbage.  In my experience amending your garden soil with aged manures and adding in lime (if your soil is acidic) will help getting the best cauliflower.  

When growing this vegetable it often will be smaller and not as white as some you can purchase in the store.  Just remember a lot of veggies we buy in stores is genetically manipulated or enhanced in some way to make them look more appealing.

Give this wonderful vegetable a try in your own garden.
