Rhododendrons do not need a rich soil. We recommend light application (i.e. a handful per average sized plant) of 2 parts blood and bone and 1-part superphosphate fertiliser, at the end of September and again in late January.

What is the best fertilizer for rhododendrons?

We suggest using Fertilome Azalea, Rhododendron, Camellia Food which should to be applied every 4-6 weeks during the growing season between flowering in spring and bud set in early fall.

Do coffee grounds make soil more acidic?

Grounds are not acidic; the acid in coffee is water-soluble so the acid is mostly in the coffee. Coffee grounds are close to pH neutral (between 6.5 to 6.8 pH). Coffee grounds improve soil tilth or structure. Coffee grounds are an excellent nitrogen source for composting.
