Collection of 3 Raspberry Bushes for a Spreading Harvest.

Raspberry bushes prefer humus-rich soil, without too much limestone, that remains moist even in summer. They appreciate partially shaded but bright exposures. They can tolerate the sun in cool climates, but prefer partial shade in warmer ones. Plant them from October to April in ordinary soil enriched with compost and well-rotted manure. Regularly water them to promote root growth in the first year of planting. During periods of high heat or prolonged drought, provide them with additional water. Raspberry bushes can be subject to various diseases if the growing conditions are not optimal (raspberry anthracnose, raspberry rust, powdery mildew, grey rot during rainy periods, or Botrytis). The damage observed in cultivation is due to unfavourable climatic conditions, especially during cold springs that allow micro-fungi present in the soil to infest the vegetation. To protect the plants, feed the raspberry bushes with organic fertilisers that promote the growth of anaerobic bacteria in the soil, thus strengthening the soil's ability to stimulate the plants' immune system. Raspberry bushes 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.
