Raspberries is the edible fruit of a multitude of plant species in the genusRubus of the rose family, most of which are in the subgenus Idaeobatus; the name also applies to these plants themselves.
PLANTING
- Raspberry plants can be purchased as dormant, bare-root plants or as potted plants. Plant bare-root transplants in the early spring as soon as the soil can be worked. Plant potted transplants in the spring after threat of frost has passed.
- Pick a site with full sun to produce the most fruit. The plant will grow in part shade, but harvests will be meager.
- Your site needs rich and well-drained soil, great air circulation, and shelter from wind. Avoid a wet area, as well as a windy spot, as raspberries do not like to stand in water nor dry out.
- Prepare soil with a couple inches of compost or aged manure a couple weeks before planting. (A good rate is about 3 ½ cubic feet of compost per 100 square feet.) Till the soil well before planting.
- Plant far from wild growing berries, otherwise risk the spread of pests and diseases to your garden.
- Before planting, soak the roots for an hour or two.
- Dig a hole that is roomy enough for the roots to spread.
- Whether you’re planting bare-root or potted plants, keep the crown of the plant 1 or 2 inches above the ground.
- Space red and yellow raspberry plants from 2 to 3 feet apart, in rows 8 feet apart. Space black and purple types 4 feet apart.
CARE
- Mulching is important throughout the season to conserve moisture and suffocate weeds. Keep a thick layer of mulch surrounding plants at all times.
- Water one inch per week from spring until after harvest. Regular watering is better than deep soaking.
- The roots send up an abundant amount of shoots, called canes. Keep order by pruning away the majority of them, so that the survivors can produce lots of berries.
PESTS/DISEASES
- Keep an eye out for spider mites and Japanese beetles from June through August.
- Rabbits love to eat the canes in winter. A chicken wire fence will help prevent rabbit damage.
- Powdery Mildew
- Cane Borers
HARVEST/STORAGE
- All varieties will begin to produce fruit in their second season. In some cases, ever-bearers may bear small berries in their first autumn.
- In early summer, berries will ripen over a time of about 2 weeks. You will need to pick berries every couple of days.
- Try to harvest berries on a sunny day, when they are dry.
- Don’t tug too hard on your raspberries when picking. A ripe raspberry will leave the vine willingly.
- Raspberries can be kept refrigerated for about 5 days.
- If the fruit is to be made into preserves, it should be done straight off the plant.
- Raspberries can be frozen. As with freezing blueberries, make a single layer of berries on a cookie sheet. When frozen, place into airtight bags.
