How to grow Romanesco Veronica Seeds
Romanesco grows best in cool weather. Buds will not develop well in extreme heat or drought. It will survive frost down to 20–25°F, although any mature heads will be damaged in a hard freeze. Romanesco does best in full sun but will tolerate partial shade. It prefers loose, well-drained loamy soils with a high amount of organic matter and consistent soil moisture. Add compost or an organic fertilizer that is higher in potassium and phosphorus than nitrogen to your soil before planting.
Sow Indoors 6 weeks before the last expected frost date. Transplant outside once the soil temperature is at least 60°F.
Sow Outdoors 2–3 weeks before the last expected frost date. For an autumn crop, sow 9 weeks before the first expected frost date.
Germination takes approximately 7-14 days and plants will be mature 75-100 days after sowing. When harvesting, leave at least 5cm of stem attached to the base.
