This spring application may be all you need, but if you live in an area with a lot of rainfall and a long growing season, you may want to make a second application in mid to late summer, making sure not to fertilize after August 1st.
The mix is well-balanced if the 3 numbers on the packaging are the same or similar. These numbers represent: (N) Nitrogen – promotes new growth/foliage; (P) Phosphorus – promotes plant blooms; (K) Potassium – strengthens roots/stems.
If you need to fertilize again, do so before August, as Encore Azaleas are sensitive to heavy fertilization. Apply liquid fertilizer directly to foliage and roots for an additional nutrient boost. Always follow label instructions and water well, no matter the brand.
