Guides
Zucchini in zone 6 go out in May and crop until the October frost
In USDA zone 6, sow zucchini directly outside from early May to early June, or start seeds indoors from late March to late April and plant out in May. Plants start cropping about 50 days from sowing and keep going until the first frost around mid-October.
Sow courgettes in late April and you'll be picking by July
Sow courgettes indoors from late March to late April and plant them out in May, once the risk of frost has passed. Or sow straight into the ground from early May to early June. Plants start cropping about six weeks after planting out and keep going until the first frost.
