The Optimist F1 winter cauliflower has a relatively long growing season and requires a location with rich, well-drained soil. Because cauliflower is a heavy feeder, it's essential to provide sufficient nutrients. Fertilizing with compost or organic fertilizer before planting promotes vigorous growth and firm heads. During the growing season, an additional application of nitrogen-rich fertilizer can help support development.

To keep the cauliflower heads a beautiful white, the outer leaves can be folded over the head as soon as the head begins to form – this protects them from sunlight and discoloration.
