Q What has caused my poinsettia to wilt?
A Poinsettias wilt when they get too hot and dry. They do best at a draught-free 15-21°C and should keep flowering for 12 weeks. To extend the flowering and keep the leaves in tip-top condition, place the pots on a pebble tray, mist the leaves and feed regularly. Put your plants in the brightest possible winter light to maintain the 'petal' (bract) colour at its best. Water the poinsettia from the top of the pot, allowing the compost to become completely dry before the next application. But if the leaves start to wilt, water thoroughly with tepid water. If your plant’s leaves start turning yellow, it means its environment is either too hot, dry or dark, or a mix of all three.
