Sweetheart was developed by the USDA breeder Dr. Mark Ehlenfeldt and introduced in 2010. It is a cross of a southern and northern highbush with the outcome of a rare multiple yielding crop. One in late May to early June and a second yield in August. You can expect up to 15 lbs. from a mature plant. This bush grows 4-6 feet tall with beautiful white blooms in the spring. It produces medium-large, plump, dusky blue berries with a pleasingly sweet blueberry flavor. Sweetheart will make a great addition to any edible landscaping and does well as a patio plant.
Planting Instructions: High Bush
Start with selecting a sunny location in well- drained soil free of weeds and well worked. Locate in an area where irrigation water is available as best results will be obtained by keeping the root zone moist throughout the growing season. Where the soil is poor or marginally drained, raised beds 3-4 feet wide and 8-12″ high work very well for blueberries. Blueberries can be planted as close as 2-1/2 feet apart. If planted in rows, allow 8-10 feet between the rows depending on equipment used for mowing or cultivating. Mulching – Blueberries do best with a 2-4″ mulch over the roots to conserve moisture, prevent weeds and add organic matter. Bark mulch, sawdust, grass clippings, etc. all work well. Repeat every other year.
