Do bedding plants get very hungry?

How often should I feed my summer bedding plants? Val, Worcester DAVID: They usually benefit from a once-weekly feed with a high-potash, low-nitrogen fertiliser. This helps to feed and prolong blooms without encouraging too much bushy leaf and stem growth. Feed plants throughout the growing season. Make sure they are well hydrated first – if soil is dry, it can burn roots and hinder water and nutrient uptake.
