Will Bone Meal Help Blueberries Grow?

Soil Requirement

• Blueberries require a very acidic soil to thrive. According to the North Carolina State University Extension, blueberries grow in a more acidic soil than the majority of small fruit. The recommended pH for blueberries is anywhere between 4.0 and 5.5. In areas with higher pH, it is recommended to plant blueberries in raised beds or containers as it is easier to maintain pH levels in smaller areas. Generally blueberries grow well in gardens that also support the optimal growth of other acid-loving plants like camellias and azaleas.

Properties of Bone Meal

• The use of bone meal raises soil pH and helps make acidic soils more alkaline. It is therefore not recommended for use with blueberries. Bone meal is obtained primarily from cow bones that are steamed and ground. The material is a form of organic fertilizer with high levels of slow release phosphorus, one of the three primary nutrients essential for optimal plant growth.

Fixing Soil pH

• The use of wettable sulfur is recommended to lower pH levels for blueberries in alkaline soils. Apply a pound or 2 ½ cups of sulfur for every 100 square feet of soil to lower a unit of pH from 6.0 to 5.0. This amount works on sandy soils. For plants that are growing in heavy soils like clay or silt, increase sulfur amount to 2 lbs. per 100 square feet. It is best to amend soils with sulfur three to four months prior to planting.

Site Conditions

• Plant blueberries in very well-drained ground for optimal growth and choose an area that receives full sun. Though plants also adapt well to areas that receive 50 percent shade, fruit production is reduced. Avoid excessive use of fertilizers as this can easily damage plants and do not fertilize immediately following planting. Apply a 3- to 4-inch deep layer of organic mulch as this conserves soil moisture and moderates soil temperatures. Recommended mulches include pine chips, bark or sawdust.
