Make sure you water the day before feeding, and don't feed on very hot days. Feed spring bloomering shrubs that are now setting buds. The exception is once blooming old roses. If you have an old rose that is a repeat bloomer, you should feed it so that it blooms well this fall. Fertilize the lawn Feed chrysanthemums and fuchsias and all other perennials about to bloom.
Check leaves to see if iron chelate is needed.
Feed azaleas, camellias, hydrangeas, and rhododendrons with an acid type fertilizer. Fertilize summer bulbs like dahlias and glads to nutrify corms, tubers, and bulbs for next year. Continue to feed peonies. Annuals, if needed Feed container plants. Fertilize berries or top-dress with compost.
