Continue regular watering, light pruning to shape, apply balanced fertilizer in spring, maintain mulch layer
Flowering
April-May (4-6 weeks)Clusters of small, white to pale pink bell-shaped flowers appear on branch tips in spring
Do not fertilize heavily (encourages foliage over fruit), ensure adequate water, protect from late frosts if possible
Fruiting

Harvest Tips
Berries fully ripen in mid to late summer (June-August depending on zone). Harvest when berries are deep blue and roll easily off the stem; they continue to ripen slightly after picking. Pick every 3-4 days at peak ripeness. Taste a sample—ripe berries are sweet and tart. Can be harvested by gently rolling berries off the stem into a container or by hand-picking individual berries.
Fun Facts
- 🌱 Blue Muffin was specifically bred as a compact blueberry for home gardeners and container cultivation, making commercial-quality fruit accessible in small spaces.
- 🌱 Blueberries require cross-pollination for best fruit production, but Blue Muffin can set some fruit on its own and will produce more abundantly with a compatible pollinator variety nearby.
- 🌱 The berries' blue color comes from anthocyanins, powerful antioxidants that give blueberries their health benefits and their distinctive color—more intense color indicates higher anthocyanin content.
