In Britain, we’re likely to get a late frost well into spring. Many people make the mistake of planting sensitive plants like geraniums, fuschias and petunias early April as it starts to get slightly warmer, and then late frosts kill them off.
Solution: Hold off planting until the end of April. May onwards is safer, and it’ll prevent you from having to replant. You can always be prepared for frost by covering your plants when a bad forecast is announced.
