Soil pH Level 6.5

Position Full sun, in a spot that follows leafy green crops such as lettuce or cabbage.

How to Plant Sow the seeds directly into the veggie patch in early autumn if conditions are not too warm, otherwise propagate in a mini greenhouse and then transplant once conditions become more mild
