Growth Stages

1

Establishment

First 3-4 months after planting

New canes emerge from base; plant develops root system and establishes growth pattern

Keep soil consistently moist, mulch heavily (3-4 inches), protect from wind damage, prune any damaged canes

2

Vegetative Growth

Spring through early summer (4-5 months)

Canes grow tall and develop lateral branches; lush green foliage expands throughout growing season

Provide support for tall canes, thin overcrowded growth, monitor for pests, maintain consistent moisture

3

Flowering

Late March to May (4-6 weeks)

Attractive magenta, pink, or occasionally yellow flowers appear on second-year canes along branch tips

Avoid heavy pruning during flowering, ensure adequate moisture for flower development, pollinate manually if needed

4

Fruiting

June to August (8-10 weeks)

Flowers develop into large berries that ripen from yellow to orange, salmon, red, or purple depending on variety and sunlight

Maintain consistent moisture as berries develop, protect from birds with netting if desired, avoid disturbing canes

5

Dormancy

November to February (3-4 months)

Foliage dies back in fall; plant enters winter rest period with canes remaining visible

Prune out dead or diseased canes in late winter, remove old fruiting canes to encourage new growth, apply dormant oil if needed

Harvest Tips

Harvest berries when fully ripe (color fully developed and berries yield slightly to gentle pressure), typically June to August. Pick every 2-3 days as berries ripen sequentially. Berries have a short shelf life and are best eaten fresh immediately after harvesting; they can be refrigerated for 2-3 days or frozen for longer storage.
