1. Raspberry cultivation in the garden

Location and Soil:

  • Location: Raspberries love full sun, so they need at least 6 hours of sunlight a day. They can grow in partial shade, but yields will be lower.
  • Soil: Raspberries prefer well-drained soil with a pH of 5.5-6.5. It’s a good idea to add compost or well-composted manure before planting. Avoid heavy clay soils that can cause root rot.

Planting:

Timing: The best time to plant raspberries is early spring or late summer. Choose healthy raspberry seedlings for a longer fruiting period.

Spacing: Plant raspberries 60-90 cm apart to allow room for growth. Rows should be spaced 1.5-2 m apart.

Care:

Watering: Raspberries require regular watering, especially during dry periods. Keep the soil moist but not soaked. A crucial care procedure is also pruning raspberries, which should be tailored to the specific type of raspberry.

Fertilization: Fertilize every 4-6 weeks with a balanced fertilizer. Use a potassium-rich fertilizer before flowering to support fruiting.

Support: Raspberries need support, especially large-fruited varieties. Use wooden stakes or special trellises.

Pruning:

  • Summer Raspberries: Prune in spring, removing all old, dead canes and leaving only new ones that will bear fruit in the current year.
  • Autumn Raspberries: Prune in autumn after harvesting, removing all canes that bore fruit.

2. How to cultivate raspberries

Choosing Varieties:

  • Summer Raspberries: Bear fruit in mid-summer. Choose disease-resistant and productive varieties like ‘Glen Ample’ or ‘Autumn Bliss.’
  • Autumn Raspberries: Bear fruit in late summer and autumn. Varieties like ‘Polka’ or ‘Heritage’ are known for their long fruiting period.

Care:

  • Watering: Regular watering is key, especially during dry periods. Mulching helps retain moisture in the soil.
  • Fertilization: Regular fertilization, especially before flowering and fruiting, is important for good yields. Raspberries should be harvested at the right time using methods that do not damage the plants, allowing you to enjoy their flavor and health benefits.

Protection Against Pests and Diseases:

  • Diseases: Raspberries can be susceptible to fungal diseases such as powdery mildew or rust. Ensure good air circulation around the plants and use plant protection products if necessary.
  • Pests: Monitor plants for pests such as aphids or spider mites. Regular checks and protective treatments will help keep the plants healthy.

3. Autumn raspberry cultivation

Requirements:

  • Varieties: Autumn raspberries such as ‘Polka’ and ‘Heritage’ are suitable for temperate climates. They bear fruit from late summer to early autumn.
  • Soil: The soil should be well-drained and fertile, with a pH of 5.5-6.5.

Planting and Care:

  • Planting: Plant autumn raspberries in early spring or late summer to give them time to establish before fruiting.
  • Care: Regular watering and fertilization are important for growth and fruiting. Prune autumn canes after harvesting, removing all fruiting canes.

4. Raspberry cultivation for amateurs

Choosing Varieties:

  • Varieties for Amateurs: Choose varieties that are easy to grow and disease-resistant, such as ‘Autumn Bliss’ for autumn raspberries or ‘Glen Ample’ for summer raspberries.

Planting and Care:

  • Planting: Raspberries are ideal for amateurs as they are relatively easy to grow. Choose healthy seedlings and plant them at appropriate intervals.
  • Care: Regular watering and fertilization are important. Pruning is essential for healthy plants and good yields.

Harvesting:

  • Timing: Raspberry harvesting occurs from summer to autumn, depending on the variety. Regularly picking fruits ensures the best results.

5. Summer raspberry cultivation

Requirements:

  • Varieties: Summer raspberries, such as ‘Glen Ample’ or ‘Polka,’ bear fruit in mid-summer. Ideal for those who want to enjoy fresh raspberries in the summer.
  • Soil: They need well-drained, fertile soil with a pH of 5.5-6.5.

Planting and Care:

  • Planting: Plant summer raspberries in early spring to give the plants time to establish before fruiting.
  • Care: Regular watering and fertilization are important. Use supports for growing canes.

Harvesting:

  • Timing: Summer raspberries are ready for harvest from July to August. Regularly picking fruits ensures the best fruit quality.

Raspberry cultivation in the home garden is an activity that brings a lot of satisfaction. Raspberries are popular fruits that can be grown in both summer and autumn varieties. However, it is important to know the differences between them and to care for them properly to enjoy delicious fruits throughout the season.

Planting Raspberries

The best time to plant raspberries is early spring or late autumn when the plants are dormant. When choosing a location, remember to ensure good drainage and a sunny spot. Raspberries grow best in nutrient-rich soil, so it’s worth preparing it in advance by adding a multi-component or organic fertilizer.

Summer Raspberries vs. Autumn Raspberries

Summer raspberries fruit on biennial canes, while autumn raspberries fruit on annual canes. In the case of summer raspberries, the fruits appear in early summer, while autumn raspberries bear fruit in late autumn. If you want to extend the harvesting period, consider growing repeat-fruiting varieties that can yield for most of the year.

Caring for Raspberries

Caring for raspberries involves several key tasks. In spring, it is advisable to prune raspberries, removing non-fruiting and diseased canes. Prune raspberries low to encourage the growth of new canes that will bear fruit in the upcoming seasons. For autumn raspberries, which bear fruit on this year’s canes, pruning should take place in early spring, removing canes that have finished fruiting.

Fertilizing raspberries is equally important. Regular use of mineral and organic fertilizers will help keep the plants in good condition and provide them with the necessary nutrients. Remember to use nitrogen fertilizers during the growth period and potassium and phosphorus fertilizers before flowering and fruiting.

Harvesting Raspberries

Harvesting raspberries occurs when the fruits reach full ripeness. Repeat-fruiting raspberries can be harvested multiple times during the season, increasing the yield. In the case of summer raspberries, the fruits are harvested in the summer, and for autumn raspberries, they are harvested in late autumn.

Growing raspberries requires some work and commitment, but with proper care, you can enjoy delicious fruits and beautiful bushes in your garden. We recommend using organic fertilizers, as this will make their cultivation more efficient. Autumn varieties in home gardens are less common than summer varieties. Nitrogen fertilizers significantly increase fruit yields.

The biennial canes in raspberry cultivation are those that grow in the first year and bear fruit in the second year. After fruiting, these canes begin to dry out and should be pruned to make room for new, younger canes. In the case of summer raspberries, biennial canes are crucial, as this is where the fruits appear.
