Raspberry plants grow best in northern climates where the spring is a long, slow warming process. They will only survive and produce fruit in warmer climates if the are grown in light shade.Raspberries need full sun for the best berry production. They should be planted in rich, slightly acidic, well-drained soil that has been generously supplemented with compost and well rotted manure.
Raspberry plants must not be allowed to dry out during their flowering and fruiting seasons. Raspberries come in four colors, red, yellow, purple and black. The purple and black varieties have rigid, upright stems and are able to stand alone.
Raspberry plants can be easily propagated in late summer by tip layering the current season’s growth. By late August new canes will begin to arch down in an effort to self-propagate. As the tips of the cane touch the soil, they will often take root and begin to grow upward without assistance.
Raspberries can be planted any time from late fall up until early spring before new growth begins. They should be planted 30″-36″ apart in rows that are spaced 8 feet apart. Plant nursery grown Raspberry plants in a prepared bed, 2″ deeper than they were originally growing.
