Choosing a Site:
Raspberries produce best in full sun, but can tolerate partial shade. Raspberries grow best on a raised bed 8-10” high and 18-36” wide. We suggest working Gypsum into the raised beds. This will help prevent root rot. The pH should be between 5.5 and 7.5. If your pH is below 5.5 add lime.
Dig a shallow hole large enough to accommodate the roots. Prune off any damaged root parts. Spread the root mass and set the plant in the ground. Raspberries should be one inch deeper than the plant grew in the nursery. Cover the roots and press firmly on the soil to remove air pockets. Fertilizing should be done 4-6 weeks later. Space plants 2-3ft apart in a row. It is wise to trellis all raspberries. A simple trellis system 6’ tall of wire supports strung between posts is preferred.
Pruning should be done in the early spring. First look for canes with no buds or no new growth. These canes were the ones that produced fruit last year and should be pruned away. This will allow better air circulation and higher quality berries.
Berries should be harvested every 3 to 6 days depending on weather and cultivation. When ripe the berries come right off the vine. To extend the shelf life, pick berries when they are dry and refrigerate as soon as possible.
