FROST ALERT

A FREEZE is unlikely before December, but it’s good to prepare for low night temperatures. Unheated greenhouses are safe — but not frost-free. Check that doors and vents are close-fitting. Have horticultural fleece handy to place over vulnerable plants at night. It will keep them 1c to 2c warmer than if left

unprotected. Spread mulch around other plants to safeguard roots.
