Website says to fertilize in early spring or summer so does that mean you only fertilize one time? But it also says follow instructions on label, which mine says feed every 14 days. I bought the Scots company garden pro water soluble miracid acid loving plant food. So do I only do this once or do I feed every 14 days?
I can understand your confusion! We do recommend fertilizing just once – either spring or early summer. Too much fertilizer isn’t necessarily a good thing. And, fertilizing late in the growing season will increase the risk of winter kill. Be certain the fertilizer that you purchased is higher in phosphorous rather than nitrogen. The middle number (P, phosphorous) on the NPK ratio should be higher than the first and last number. Phosphorous is the nutrient that helps hydrangeas grow flowers.
