3. Preparing your Seeds
Before planting cauliflower seeds the first thing that you should do is to check for the recommended planting dates for your particular climatic zone.
Generally speaking, you want to start seeds a month to six weeks before the last forecasted frost date. Cauliflower grows best when it is started in seed trays with some seed compost instead of multipurpose compost.
When you are ready to plant your seeds you will want to plant one or two seeds in each cell. You should push them in at about a half-inch depth. If both of the seeds germinate, choose the one that is most robust and snip the other one using gardening shears.
Do not pull out the second plant as this can cause damage to the roots of the stronger plant. Place the seed tray in a greenhouse and gently wet it. It will take about four weeks for the seeds to germinate.
