Rubus idaeus Sumo 2 - Raspberry

The Raspberry prefers humus-rich soils that retain moisture, even in summer, without too much chalk. It appreciates partially shaded but bright exposures. In the north  it will tolerate the sun well, while in the south, it prefers partial shade. Plant from October to March, in ordinary soil enriched with compost and well-rotted manure.

Place the plants every 80cm (31.5in) on rows spaced 1.50m (4.9ft) apart. For bare-root plants, soak the roots for a day to prevent the formation of air pockets between the roots and the soil. When planting, the collar should be level with the ground. It is recommended to train them with wire between stakes or on a trellis.

Water regularly to promote root growth in the first year of planting. During periods of high heat or prolonged drought, provide additional water. Weed the surface, especially at the beginning of planting and apply mulch to retain moisture in summer.

The Raspberry can be susceptible to various diseases if the growing conditions are not optimal (raspberry anthracnose, raspberry rust, powdery mildew, grey mould in rainy periods, or Botrytis). The damage observed in cultivation is due to poor weather conditions, especially during cold springs that allow micro-fungi present in the soil to infest the vegetation. To protect the plants, it is recommended to feed raspberries with organic fertilizers that promote the multiplication of anaerobic bacteria in the soil, strengthening the soil's ability to stimulate the plant's immune system. Raspberries can also be attacked by certain pests such as raspberry worms, the larvae of a small beetle that lodges in the fruits, without causing significant damage.

Raspberries easily multiply through suckers that grow near the base: dig them up and replant them in another part of the garden if desired.
