Frequently Asked Questions

When should I pick Marrow for the best flavor?

Harvest the fruits young and tender — letting Marrow grow too large results in tougher, less flavorful flesh, so pick regularly to keep the vigorous vining or bush plants producing.

Is Marrow the same thing as Courgette?

They're the same species (Cucurbita pepo) grown differently — Marrow is typically left to grow larger than Courgette, giving it a milder, more versatile flesh that's a staple in British and Mediterranean cuisine.
