Weed and Feeds kill both weeds and grass, but you don’t want to apply it to your hydrangeas. Weed and feed products typically contain a high level of salt and can cause leaf burn. It is best to use a granular fertilizer and water it in well so the salt does not burn the leaves. This will also give the nutrients time to be absorbed into the soil and foliage.

For weed and feed fertilizer for hydrangeas, there are a lot of options available. While there are several factors that go into fertilizer selection, the first thing that you should look for is if there is a balance in the fertilizer or not. 

A balanced fertilizer will include the three major nutrients, nitrogen, phosphorous, and potassium. A lot of weed and feed fertilizers have no balance, so read the ingredients list.

The main nutrients that hydrangeas need come from the soil and the water, and the weed and feed only provide three of the nutrients that your hydrangeas need: nitrogen, potassium, and phosphorous. If you’re using a high quality granular fertilizer that is made for flowering plants, then you should get enough nutrients to sustain your hydrangeas through the growing season.
