Seed preparation

As with any crop, broccoli seeds are soaked before sowing. For this purpose, wet gauze folded in several layers is used.

Seeds of hybrids (F1), as a rule, go on sale fully treated with all necessary preparations against plant diseases and against pests. They are fully prepared for sowing, so they are sown dry or treated with growth stimulants.
