There are some things to plant with raspberries. Raspberries grow mild in some places in the USA. Raspberries grow really well in in well drained, slightly acidic soil that has lots of organic materials in it. Before planting, you may want to add some organic materials and nutrients. Growing a cover crop is also a good idea.
Key Takeaways:
- Raspberries grow wild in most places in the U.S., planted here and there by birds or spreading from prolific underground runners.
- Under this assumption, you buy some raspberry plants and stick them in the ground, but all season they struggle and produce very little fruit.
- One way to do this is to plant and grow a cover crop for one season prior to planting raspberries in that location.
