What is the best fertilizer for Fothergilla gardenii shrubs?

Answer 1

An acidifying fertilizer or compost are the best fertilizers for gardenia shrubs (Gardenia spp).

Specifically, gardenias appreciate soils that are more acidic than neutral. They therefore benefit from acidifying fertilizers that keep the soil pH below the neutral range of 6.5-7.0 on the 1-14 scale. They get the same benefits when compost is applied at fertilizer along the drip line or as mulch. Additionally, compost as mulch controls weedy competitors, favors drainage, increases soil fertility and keeps temperatures even.

Answer 2

Compost is the best fertilizer for dwarf witchalder shrubs (Fothergilla gardenii).

Specifically, dwarf witchalder shrubs do not have to be fertilized when they grow in grass, ground cover, lawn or turf that benefits from regular fertilizer applications. But as is the case with many herbaceous and shrubby plants, it responds well to compost, either as fertilizer along the drip line or as mulch. Either way, the shrubs take in by the roots the slow but direct and steady release of nutrients from the compost. The compost also works to control weeds, keep in moisture and maintain even temperatures.
