Frequently Asked Questions
How do I stop leafy greens bolting to seed in summer?
Heat and long daylight hours are the main triggers, so timing matters more than technique — sow through the cooler months, and switch to heat-tolerant substitutes over summer.
Do leafy greens need full sun?
Not necessarily — most leafy greens tolerate part shade well, and a little afternoon shade in a hot climate can actually help prevent bolting and bitter leaves.
