Caroline raspberry has a larger berry than Heritage and is more productive, with a rich, full, and intense raspberry flavor. It is a very vigorous variety, with more tolerance for root rot than Heritage. The farther south you grow it, the earlier it will ripen. Caroline is widely adapted, growing everywhere from the East Coast to the West Coast. This variety does not tolerate high heat and drought.

Maintain your Raspberry Plants
- 1" – 2" rainfall or equivalent per week throughout the growing season.
- Side–dress the row(s) with ¾ lb – 1 lb of 10–10–10 per 100 sq ft in the Spring Commercial growers should use 500 lbs per acre or fertilize according to soil test.
- Side–dress again in July and August.
- Occasionally test your pH and make amendments to keep the soil pH between 6.0–6.5.
- Do not fertilize in the fall.
- Regular cultivation is necessary during growing the season.
- Roots are shallow–don’t cultivate more than an inch deep.
- Contact your local extension for chemical recommendations.
- We do not recommend mulching your raspberry plants after the establishment year.
- We strongly recommend keeping plants supported by a trellis.
Ever–bearing (Fall–bearing) varieties
- To have one highly productive Fall crop, mow or cut all canes to the ground in the early Winter or early Spring while the plants are dormant. Always leave as little stub as possible.
- To produce an earlier crop as well as a Fall crop, prune as a Summer-bearing variety.
- After harvest, cut canes that fruited at the base of the plant. Leave as little stub as possible.
- Cut weak damaged or diseased canes at the base.
- Cut more canes if needed to leave 6–8 canes per running foot of row.
Don't forget Grower Accessories
Healthy berry plants require these important elements:
- Early planting! Plant as early as possible in the spring. Snow or occasional frost will not hurt most new plants (green tissue culture plants excepted), and spring rains will foster growth. Planting in the fall is not recommended in the Northeast and Midwest.
- A sunny, weed-free location with at least a half-day of sunlight.
- Clean beds that are frequently weeded.
- Well-drained soil. For poor drainage conditions, consider raised beds.
- Proper soil pH. Matching soil pH to plant requirements can be a huge factor in your success. Sample the soil before planting and contact your local cooperative extension office for assistance.
- Crop rotation. Avoid planting strawberries or raspberries in soils where previous crops have included strawberries, raspberries, potatoes, tomatoes, eggplant or peppers. These crops may harbor the soil pathogens Verticillium, Phytophthora and nematodes and may affect your new plants.
- Irrigation. Maintain proper moisture levels throughout the season and, most importantly, during the establishment period. Drip irrigation is imperative when planting in raised beds.
Avoid Common Mistakes
- Read free planting guide 1-3 months before planting.
- Plants will fail to flourish if roots are too deep or too shallow.
- Pack soil firmly around the roots.
- Do not plant near wild plants or plants whose origins are unknown.
- Water well one to three times a week, not every day.
- Avoid fertilizer burn by fertilizing only after plants are established.
- Do not soak plants in water more than 1 hour!
- Plants orders shipping to CA, OR, WA and HI will be charged a $15.00 fee for phyto-sanitary inspection.
- From Mid-May on, (depending on seasonal weather) orders shipping to states with a 4 or 5 Day ground transit time from MA will automatically be upgraded to 3DAY expedited shipping so that plants will arrive in optimal condition. This will be reflected in shipping charge.
- All plants are dormant, bare root, and ship from our Massachusetts nursery.
- We do not ship online orders outside the US.
- We use Federal Express as our standard shipper
- For large commercial orders, we offer various methods of Truck Shipments
