Keep in mind when planting that Green Windsor is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea).
Aim to sow
1.95 inches (5.0 cm) deep and try to ensure a gap of at least
9.75 inches (25.0 cm).
By our calculations, you should look at sowing Green Windsor about 21 days before your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Green Windsor is a hardy plant.
The Green Windsor is the main ingredient for “Brown Windsor Soup”.
