Frequently Asked Questions

Does Kale really taste better after a frost?

Yes — frost improves flavour by converting starches to sugars, giving Kale a sweeter, milder taste. It's hardy enough to survive frost and can be harvested throughout winter in many climates.

How much fertilizer does Kale need?

It's a hungry feeder — a high nitrogen feed applied monthly supports its dense, nutritious leaf growth, since Kale is one of the most nutritious vegetables you can grow and rewards regular feeding.
