Use holly bush cultivars for hedges, foundation plantings, stand-alone shrubs or accent plantings.
Holly prefers acidic soil with a pH level of 5.0 to 6.0. Soil testing confirms the pH level. Test the soil before planting and amend according to test results.
Ohio State University recommends mulching with organics such as sphagnum peat moss, pine needles, pine bark or chopped leaves. Organic mulch slowly releases nutrients.
Scatter a handful of balanced fertilizer such as 8-8-8 or 10-10-10, referring to ratios of nitrogen, phosphorus, and potassium, in late spring. Sprinkle the fertilizer on the mulch and water well.
Apply agricultural sulfur as needed to reduce soil acidity. Ohio State suggests maintaining soil under pH 6.
