Cut your herbs and they’ll rise again

My windowsill herbs are getting a bit leggy. What should I do? – Jonny, Bromley, Kent DAVID: Keep eating them to stop them getting leggy. Cut off the leaves to use in garnishes and sauces.

Regularly using herbs like basil and mint keeps them healthy. Feed them to give them energy, and be sure to pinch off flower heads – they take strength from foliage.
