Fertilize in spring with blueberry-specific fertilizer. Prune to maintain open center and remove diseased wood. Continue mulching
Flowering
4-6 weeks, typically April-May depending on zoneBell-shaped white to pale pink flowers appear in clusters along branches
Protect flowers from late frosts if possible. Avoid excessive nitrogen which reduces flowering. No pruning during flowering
Fruiting
6-8 weeks, June-JulySmall green berries develop and gradually swell and ripen to blue color with silvery bloom coating
Maintain consistent watering during berry development. Monitor for pests and disease. Birds may require netting for protection
Harvest & Dormancy

Harvest Tips
Berries are ready to harvest when fully blue with white powdery coating (bloom) and easily detach from the stem. Pick in morning after dew dries. Catskill berries ripen progressively over 2-3 weeks in July. Ripe berries will not ripen further after picking. Leave slightly underripe berries for next picking day—fully ripe berries are delicate. A mature plant can yield 4-8 pounds per season
Fun Facts
- 🌱 Catskill was developed by USDA scientists at the Genetic Resources Unit in New York and released in 1981, specifically bred for cold hardiness and reliability in northern climates
- 🌱 Blueberry plants can live 30-50+ years with proper care, with some wild highbush specimens exceeding 100 years old, making them a long-term garden investment
- 🌱 Catskill is largely self-fertile, unlike many other blueberry cultivars, but cross-pollination with other highbush varieties like Duke or Blue Crop increases berry set and yield
