Keep up your harvesting
Dig up the last of the leeks before they flower. In a warm spring, this can happen in just a few days, so catch them before they get ruined.
Keep picking the leaves of spinach, chard and salads. These plants will have perked up after the winter to provide a useful source of leaves but will also accelerate into flowering, so cut out any shoots that emerge from the centre of the plant. You’ll eventually lose the battle as they run to flower and seed, and they’ll then have to be lifted and put on the compost heap. Also, get ready to pick the new shoots of early brassicas such as purple sprouting broccoli.
