A natural fertilizer for ericaceous and other acid loving plants. Pro-Holly 4-6-4 is a natural fertilizer blended from mineral and organic ingredients specifically made for ericaceous/acid loving plants.
PRO-HOLLY 4-6-4 is a natural fertilizer blended from mineral and organic ingredients specifically made for ericaceous/acid loving plants such as: Azaleas, Blueberries, Chrysanthemums, Ferns, Gardenias, Rhododendrons, Heaths, Heathers, Huckleberries, Hydrangeas, Marigolds, Mountain Laurels, Oak trees, Pachysandras, Lupine, Raspberries, Yews, Flax, and other acid loving plants.
Acid loving plants don't really love acid, but they need certain nutrients that become more available in soils with a lower pH (acid soil). These nutrients include iron, manganese, and sulfur. Many of these plants respond to base nutrients such as calcium, magnesium, and sodium with stunted growth, discoloration and stress related problems. Soils with a near neutral to alkaline pH generally contain more of these base nutrients.
Another misconception many people have about acid-loving plants is that they grow well in a poor soil. An acidic soil is not necessarily one that is in poor condition. It can be an environment that is rich in organic matter and soil nutrients. Acid loving plants, like most other plants, prefer more healthy soil conditions. Ample levels of organic matter increase the water holding capacity of the soil and provide a habitat for larger populations of microorganisms which, in turn, increase the soils nutrient exchange activity. Applications of Pro-Holly 4-6-4 provide nutrients not only for plants but also feed a multitude of beneficial organisms living in the soil.
Applications of 1 pound of Pro-Holly 4-6-4 per two feet of crown diameter spread under the drip line of the plant in the fall and again in spring are recommended. The feeder roots are close to the surface of the ground and spread from under the plants branches to well outside the dripline. Pro- Holly 4-6-4 should be broad cast in this area around the entire plant if possible. The fertilizer can be applied over mulch layers but the plant will respond faster if the mulch is removed and replaced after the fertilizer has been applied.
