Establishment
First 1-2 yearsYoung vines are planted as rooted cuttings or runners and begin establishing root systems in acidic bog soil.
Keep soil consistently moist; control weeds aggressively; apply mulch to suppress competition; avoid allowing vines to dry out
Vegetative Growth
Year 2-3Vines spread horizontally and develop upright fruiting shoots; foliage becomes dense and darkens to deep green.
Allow vines to develop full canopy coverage; maintain consistent moisture; remove any dead wood; continue weed control
Flowering
Late May to early July (4-6 weeks)Delicate, pale pink to white flowers appear on upright shoots in early summer, attracting pollinators.
Ensure adequate pollinator access; avoid pesticide applications during flowering; maintain consistent moisture to support flower development
Fruiting & Maturation
July through SeptemberSmall green berries develop and gradually enlarge, turning red by late summer as they mature and develop full flavor and color.
Maintain consistent soil moisture; avoid overhead watering once berries reach full size; monitor for pest damage; begin applying fungicides if disease pressure is present
Harvest
September through NovemberFully mature berries are deep red and ready for commercial or home harvest in fall.
Harvest when berries are firm and deeply colored; use wet or dry harvest methods; store in cool conditions immediately after harvest

Common Pests
-
Monitor for moths in spring; apply Bacillus thuringiensis (Bt) during larval stage; remove affected berries; rotate insecticide classes if chemical control needed
-
Flooding during dormant season to kill pupae; insecticide applications targeting larvae in early summer; maintain vigorous plants through proper culture
-
Monitor trap catches; apply Bt or spinosad when larvae are present; flooding post-harvest can reduce overwintering population
-
Monitor for stippled foliage; manage water levels to reduce habitat; insecticidal soap in severe infestations
-
Maintain healthy plant vigor; flood in spring to kill pupae; avoid over-applications of nitrogen

Harvest Tips
Howes cranberries are typically harvested in fall (September-November) when berries are fully colored and firm. Use wet-harvest method (flood the bed and mechanically collect floating berries) for maximum yield and efficiency, or dry-harvest by hand-picking for premium fruit. Berries should float to indicate maturity. Harvest when at least 75% of the fruit is fully red. Store in cool, humid conditions (32-40°F, 90-95% humidity) for extended shelf life.
Fun Facts
- 🌱 Howes cranberries were named after A.D. Howes, a prominent cranberry grower in Massachusetts who developed the cultivar in the early 1900s for superior storage quality.
- 🌱 Cranberries float due to small air pockets inside the fruit; this is why wet harvesting is so efficient—the berries can be coralled and collected as they float on flooded beds.
- 🌱 A single cranberry vine can live for over 100 years and continue producing fruit, making cranberry beds multi-generational agricultural investments.
