Factor Value
Soil texture Loam or sand (RHS); peaty or light loam with leaf-mould preferred (PFAF)
Drainage Well-drained or moist but well-drained, suited to boggy conditions (RHS); PFAF says moist or semi-boggy and dislikes drying out
Lifecycle Evergreen shrub. RHS records 10-20 years to reach maturity; PFAF gives a considerably faster timeline of about 5 years to come into full bearing, after which it can crop for 60-100 years.

Water: Keep moist all year round; genuinely boggy conditions suit it well (RHS). Needs shelter from strong winds (PFAF).

Growth Stages

Many cranberries ripening across a low mat of foliage — “Ecomare - cranberry in de duinen (cranberry-duinpark-sd)” by Ecomare/Sytske Dijksen is licensed under CC BY-SA 4.0.

Stage BBCH Notes
Planting and establishment 0 Propagate by softwood cuttings in late spring or semi-ripe cuttings in early summer (RHS); PFAF adds seed (needing about 3 months cold stratification), layering (about 18 months) and spring or early-autumn division of suckers as alternatives. Needs permanently moist, lime-free, acidic soil (pH 4-4.5) -- becomes chlorotic if lime is present (RHS; PFAF).
Vegetative spread 3 Long, slender, creeping stems root into the soil as they spread, forming a low, prostrate mat; upright flowering stems develop from the second year onward (RHS; PFAF). Nutritionally poor soil is tolerated well and can actually favour fruiting over excess foliage growth (PFAF).
Flowering 6 PFAF records flowering from June to August.
Fruiting and harvest 8 Productive fruiting begins by the third year (RHS); berries mature from September through early winter and should be picked before the first frost (RHS). Bird protection with netting may be needed.

Harvest & Storage

When to pick: Red fruit, 1-2cm diameter, ripens from September through early winter; pick before the first frost (RHS). The fruit is too acidic for most people's tastes eaten raw and is mainly used cooked, in sauces, pies and preserves (PFAF); it is particularly high in antioxidants and vitamin C (RHS).

Plan your Cranberries planting

When to sow and plant Cranberries depends on your own frost dates. Check the USA vegetable planting calendar. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.

Frequently Asked Questions

What problems affect cranberries?

Our data links 4 diseases and 1 pest to this crop. See the sections above for each one and how to manage it.

Plan next season before the problems start

Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.

How this guide is put together

The growing data on this page — planting windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against USDA hardiness-zone and frost-date data, with Cooperative Extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
