Pounce on seeds when time is ripe

I’m keen to grow new plants from my existing garden. When can I collect seed? – Mary via email DAVID: You have to wait until seeds are ripe because unripe seed won’t germinate, which means waiting until late summer to autumn for most plants. But watch the specific plant you want closely so you can judge when it is ready for harvesting. It can be hit and miss so collect as many as you can for the best chance.

Nuts and bolts of stressed-out veg

How can I stop my root crops from bolting? – Jack Doyle, London DAVID: Bolting – when plants or veg prematurely run to seed – is usually caused by stress such as drought. The plant believes it’s in trouble so reproduces quickly. The best thing you can do is make sure the soil stays moist – but not sodden. If they do bolt, best to chuck them on the compost heap.
