What blueberry plants grow best in Wisconsin?
What cultivar of blueberry should I use? When selecting blueberry plants, choose half-high bush cultivars as they are hardier in Wisconsin, and are relatively short in stature. Some popular half-high cultivars recommended for Wisconsin (i.e., hardy in zones 3 though 5) are ‘Northblue’, ‘Northsky’, ‘St. Cloud’, ‘Polaris’, ‘Chippewa’, ‘Northland’, and ‘North Country’. You can also select low bush blueberry cultivars such as ‘Top Hat’ (hardy to zone 5) for container production. Low bush cultivars have a dwarf (i.e., maximum 12 inch height) and spreading growth habit and typically produce smaller fruit. Most blueberry cultivars are self-fruitful and do not require another cultivar for cross pollination (‘St. Cloud’ and ‘Polaris’ are exceptions). In general however, growing more than one blueberry cultivar will improve pollination and enhance yield and berry size.

Make sure you follow the recommended rates described on the fertilizer label.Slow-release fertilizers will typically need to be supplemented periodically (usually every two weeks) with more fast-acting acidic liquid fertilizers (e.g., Miracid) when the blueberry plants are actively growing during the spring through mid-summer.
