Master Gardener Q&A: Gifting raspberry starts not best idea

Question: I got some raspberry starts from my neighbors but am not getting them to grow very well. How do I grow these things?

Answer: Part of the problem is the source of the plants. Unfortunately, raspberries are susceptible to insect or pollen-transmitted viruses, so over time, these viruses infect the plants and weaken them. If you get starts of these plants from a neighbor, they will come to you with these viruses, so your plants may lack vigor. It is better to start with nursery-raised plants that are virus-free. Although you’ll have to purchase them, they are a better way to begin.

Another problem with raspberries is soil. They are best grown on a raised bed to avoid problems with root rot. After you amend your soil with organic matter, form a bed about 1 foot tall and 2 to 3 feet wide before planting. Also ensure that your site is in full sun, and remember that raspberries require regular summer water to thrive.

See the Oregon State University Extension publications EC 1306 “Growing raspberries in your home garden” and PNW 655 “Raspberry cultivars for the Pacific Northwest” for more information.
