You should feed your bedding plants every time you water them by diluting liquid plant food in the water.
Bedding plants are fast-growing and seasonal, usually categorised as spring bedding plants or summer bedding plants. Because they are fast-growing, most bedding plants deplete all food in their compost within just four to six weeks of planting. Therefore, they require feeding as well as watering, to keep them healthy and blooming all season.
Liquid plant food is an easy way to feed your bedding plants while watering them, simply by diluting the plant food in your watering can. Plant food contains nutrients and natural growth stimulants to help boost strong root growth and yield. Feeding your spring and summer bedding plants every time you water them can increase growth and longevity.
