It’s not too late to sow seeds, and kids love to watch them grow into little plants. Cress and lettuce are very fast-growing.
Get older children help you to take cuttings and pot them up. You can take cuttings from shrubs and perennials, such as fuchsia, choisya, lavender, hydrangea, petunia and pelargoniums.
Take a 10cm cutting from a new shoot that isn’t flowering. Cut just below a leaf joint and replant in gritty compost. For shrubs, dip the tip in rooting hormone before replanting. The cuttings will need to go in a propagator, or cover the pots with a plastic bag and place out of direct sunlight.
