Raspberry Malling Promise- Rubus idaeus

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

Plant the seedlings every 80 cm (32in) in rows spaced 1.50m (5ft) apart. When planting, the collar should be level with the ground. It is advisable to train them with wire stretched 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 subject to various diseases if the growing conditions are not optimal (raspberry anthracnose, raspberry rust, powdery mildew, grey mold in rainy periods, or Botrytis). The damage observed in cultivation is due to unfavourable weather conditions, especially during cold springs that allow micro-fungi present in the soil to infest the vegetation. To protect the plants, it is advisable to fertilise raspberries with organic fertilisers that promote the multiplication of anaerobic bacteria in the soil, thereby strengthening the soil's ability to stimulate the plants' immune system. Raspberries can also be attacked by certain parasites such as raspberry worms, the larvae of a small beetle that lodges in the fruits without causing significant damage.

The Raspberry can easily be propagated by suckers that grow near the base: remove them and replant them in another part of the garden if desired.
