Rocalba organic Ramoso Calabrese broccoli seeds, very resistant to cold weather
Broccoli (Brassica oleracea) belongs to the Cruciferae family. It is a plant very resistant to low temperatures (down to -5°C), producing deep green compact flower heads on a thick and strong stem.
It requires a substrate rich in nutrients especially N and K. Thus, it is advisable to use a mixture of peat, perlite, vermiculite and worm humus with quality compost, with aerated texture and maintaining a good humidity retention. The substrate should be provided with sufficient fertiliser for a proper development.
The seeds are germinated in late summer (August-September) by placing them in a seedbed or small pot at 0.5cm depth and with the soil not compacted. It requires a considerable light and a stable temperature. When they reach about 10-15cm, they are ready to be transplanted.

Once planted, they require the substrate to always be moist but not waterlogged. It is very convenient to install an automatic irrigation system to facilitate this task and avoid constant control of the substrate's condition.
In order to facilitate moisture retention, the soil surface can be padded with a vegetable layer. Also, padding the trunk makes it easier to keep the plant upright. It is advisable to plant in rows, with each plant about 50-60cm apart, as they grow quite large when fully grown.
They are ready to harvest between December and March. First the central heart is harvested, so new secondary inflorescences sprout which can later be collected increasing the production.
