If your baskets are showing signs of stress after overzealous watering, it may not be too late to help them recover, says gardening expert John Negus. 'Start by removing the plants and reset your charges in fresh compost,' he says, recommending a mix of two-thirds potting compost and one-third coarse grit. Work in slow-release fertilizer granules, and don't line the baskets with paper, as it may trap moisture, he adds.
'Consign your baskets to the greenhouse to become established. Then, when they are looking perky, gradually harden them off before positioning them outdoors.'
