Introduction
Blueberry 'Sharpblue' (Vaccinium corymbosum 'Sharpblue') is one of the most popular low-chill blueberries for Florida, producing medium to large, flavorful berries over a long harvest season. It is a moderate warm-season shrub that is vigorous, productive, and well-suited to the state's warm climate. Available in a #5 container for a more established plant.
Growing conditions
- Light: Full sun.
- Water: Moderate; keep soil consistently moist.
- Soil: Acidic (pH 4.5 to 5.5), well-draining, organic-rich soil.
- Fertilizer: Acid-forming fertilizer such as azalea or blueberry formula in early spring and again in early summer.
- Season: Warm-season fruiting shrub; low-chill requirement makes it ideal for Florida.
Planting tips
Plant with another variety such as 'Gulf Coast' or 'Emerald' for best cross-pollination. Space plants 4 to 6 feet apart. Mulch with pine bark or pine straw to maintain soil acidity and retain moisture. Prune lightly after harvest to encourage new fruiting wood.
Troubleshooting
Yellowing leaves
Iron chlorosis from high soil pH. Lower pH with sulfur amendments and use acid-forming fertilizer.
Poor fruit set
Lack of cross-pollination. Plant a second compatible variety nearby.
Root rot
Overwatering or poor drainage. Improve drainage and reduce watering frequency.
Pet safety
Blueberries are non-toxic to pets and are generally safe if consumed in small quantities.
Quick care summary
