How to Plant a Sunshine Blue Southern Highbush

Southern Blue is a southern highbush type of blueberry bush. It is a semi-dwarf blueberry, growing to 3 feet tall with an equal spread. Southern highbush varieties require fewer chill hours than their northern counterparts and the Sunshine Blue only requires 150 hours. Sunshine Blue does best when grown in full sun in zones 5 through 10 on the U.S. Department of Agriculture Plant Hardiness Zone Map. All blueberries require acidic soil and the Sunshine Blue is no exception.

      Loosen the soil in a 2-foot-square area, 1 foot deep. Remove half the soil and add the same amount of moist peat moss to the area. Combine the peat moss with the soil.

      Dig a hole the same depth as the blueberry's pot and three times the diameter. Place the blueberry's roots into the hole and fill it one-fourth of the way with soil. Fill the hole with water and when it drains, add soil until the hole is three-quarters full. Add water again, allow it to drain and then finish filling the hole with soil. Use your hands to pack the soil around the base of the Sunshine Blue bush.

      Spread a 2-inch layer of mulch on the soil around the blueberry bush. Pine needle or bark is the ideal mulch material for the Sunshine Blue southern highbush. Mulch helps to regulate soil temperature, keeps the soil moist and discourages weeds. Pine needles help maintain the soil's acidity.
