When to plant raspberry
- Transplant out: ~-6 weeks after last frost.
Companion plants for raspberry
Plant with: Garlic, Chives, Yarrow.
Avoid near: Potato, Tomato, Blackberry (shared disease).
Common pests & problems
Japanese beetle, spotted-wing drosophila, cane borer.
Feeding & fertilizer
N-P-K ratio: Balanced 5-5-5, avoid fresh manure
Organic options: Compost mulch every spring · Blood meal + bone meal before flowering · Kelp meal after harvest
When to feed: Base feeding on a soil test and on how much new growth the plant made last year.
Watch for: Lots of leafy growth but little fruit = too much nitrogen.
N = nitrogen (leaves), P = phosphorus (roots and flowers), K = potassium (fruit and disease resistance). How to read a fertilizer label →
Grower's tip
Prune old floricanes (fruited canes) to the ground each winter. Everbearers can be mowed for one fall crop.

Soil & water for raspberry
Soil & pH
6.0-7.0 for most; confirm with a soil test
Deep, well-drained soil. Standing water around the roots causes root and crown rot.
Test soil before planting and correct pH then. Mulch with compost each spring, kept a few inches off the stem or trunk.
Watering
1-1.5 in / week; 2 in during fruit swell
Drip or soaker at the root zone. Keeping leaves and fruit dry lowers fungal disease.
Check soil 6 in down; water when it is dry there. Drought while fruit is sizing gives small fruit.
Knowing when to harvest
- Berry pulls off the receptacle with a gentle tug: leaves a hollow center.
- Pick every 2-3 days at peak; berries do not store.
- Refrigerate within an hour; sugar peaks at picking.
Storing & keeping
Single layer in fridge. 3-5 days. Freeze on a tray then bag; keeps a year.
What to expect
Per plant: 1-2 lb per cane; 5-10 lb per mature row
Troubleshooting raspberry
Wormy berries
Likely cause: Spotted-wing drosophila (SWD)
What to do: Netting (0.98 mm mesh); pick every 2 days; refrigerate to kill larvae.
Wilting canes with a swollen ring near soil
Likely cause: Cane borer
What to do: Cut and destroy affected canes below the ring.
Varieties worth the space
Not every name in a seed catalog. These are the ones growers order again, with what each one is actually good at and what it asks of you.
Heritage
Open-pollinated
Fall-bearing on new canes, mow the whole patch each winter and pruning is solved.
Anne
Open-pollinated
Yellow fall-bearer, honey-sweet, doesn't ship at all. A homegrown-only fruit.
Boyne
Open-pollinated
Summer-bearing and hardy to −35°F. The zone 3 raspberry.
Heritage (everbearer)
Fall crop; mow the whole patch each winter for easy upkeep.
Nova (summer-bearer)
Cold-hardy zone 3; big traditional summer crop.
Anne (yellow everbearer)
Golden berries, honey-sweet, ignored by birds.
Growing raspberry in containers
20+ gallon container; everbearing varieties only.

Common questions
Everbearer or summer-bearer?
Everbearer if you want simple pruning (mow to ground each winter). Summer-bearer if you want a bigger, concentrated harvest.

- NOAA NCEI 1991-2020 Climate Normals. Frost dates, growing-season length, and the probability bands on both.
