Holly-tone is an organic & natural fertilizer that's not just for Hollies. It can be used for any acid-loving plants, such as blueberries, camellias, rhododendrons, evergreens, hydrangeas and more. You will want to fertilize your plants twice a year – In early spring and late fall.

Holly-tone ® is a fertilizer designed to feed plants that prefer to live in acidic soils. Some examples of acid-loving plants are: azalea, dogwood, rhododendron, ferns, hemlock, holly, hydrangea, juniper, arborvitae, magnolia, Japanese Andromeda (pieris), pachysandra, vinca and many other evergreens.

Espoma Holly-tone is an excellent choice for blue hydrangeas since it contains sulfur to lower pH. Espoma Plant-tone is ideal for feeding pink hydrangeas since it does not contain the additional sulfur.

Fertilizing Your Arborvitae After planting, we recommend applying a slow-release fertilizer, such as Espoma Holly-Tone. Slow-release fertilizer also provides additional acid to the soil, which allows Arborvitae to thrive.
