How to Grow

For optimal blueberry plants, choose a site with direct sunlight that is shielded from strong winds. Avoid areas that are poorly drained or prone to early frost. Blueberries prefer sandy soils with good drainage that are rich in organic matter. Clay soils should be avoided.

All perennial weeds should be cleared prior to planting. In preparing your soil, make sure to test the pH and fertility of the soil. Unlike other garden crops, blueberries need an acidic soil for reason able growth, so soil should be between 4.5-5.5. Space blueberries 1 to 1.5 meters apart and leave 2 to 2.5 meters between each row of blueberries.

After planting, consider adding a layer of straw n order to conserve soil moisture, reduce temperature variations as well as weed growth. Wood chips, shavings and pine bark may also be used in addition to or instead of straw.

However, before applying, check to ensure the soil contains no seeds of weeds and if the soil is damp. Blueberry plants must be watered regularly throughout the growth period. Try to keep the soil moist but not wet. Rainwater is ideal for watering.

Ensure that if you plant blueberries in a pot, that black pots are avoided, as they absorb heat and reduce moisture much faster. If using drip irrigation, place two emitters, one on each side of the plant.
