12. Use a Trellis
Raspberries bushes grow tall, and they require support to ensure that they don’t fall over. When raspberry bushes touch the ground, the foliage dies off, and the canes start to experience the onset of disease. Prevent your plant from falling over by using a straight trellis on a wall to support your raspberries. Raspberries like the morning sun, so make sure your place your trellis on an east-facing wall.
If you decide to grow your raspberries in a greenhouse, then build a trellis fence on one side of the flowerbed. Drive 8-ft stakes into the ground, at least 2-feet deep. Attach the trellis to the poles, and your raspberry bush is ready for training.
As the raspberry plant grows, weave the canes into the trellis to support its growth. This strategy places less stress on the plant, resulting in larger and sweeter raspberries during harvest season. Always build your trellis before the plant gets over 2-feet tall, as it may be challenging to support the canes when they get too large.
