Planting against a fence or house is useful for supporting plants, but make sure they’ll get enough sun. If you aren’t sure where to plant, watch your yard throughout the day to see where the best sunlight is.
If you are planting somewhere that’s never been planted, tilling is even more important. If you’ve planted before, you don’t need to till quite as thoroughly. Boysenberries grow well in sandy, loamy, or clay-rich soil. They need moist soil, but they are also resistant to drought.

When you use two pieces of wire, attach one to the poles at three feet (. 9 m) and the second at one and a half feet (. 45 m).
The main goal is to plant the boysenberries near something they can cling to and be tied to. Otherwise, they will slump over and produce less fruit. Set up a ladder, an old kitchen chair, or stick a broom handle into the ground. Tie the plants to these to support them as they grow.
Boysenberries are pretty resilient in the face of cold weather, so they can handle if it stays cold for a little while after you plant them. Plants grow into full size throughout the summer.
If you want to add a big shovelful, it won’t hurt. Also, mix some compost into the soil you’ll pack around the plant once you bury it.
If you don’t have much room, you may want to consider only planting one or two plants. Otherwise, set your plants up in more than one space in your yard so they have room to grow. Another option, if you have limited space, is to grow the plants in containers. However, keep in mind that container-grown plants will need heavy pruning in order to keep the plant from getting oversized.
Don’t let the soil become dry. Get a soil moisture meter from your local garden store or order one online. This makes it so you don’t have to guess if the soil is moist enough.
Use twine or thin string to tie the plants up. Tie them first at the one and a half foot (. 45 m) high wire, then at the three foot (. 9 m) high wire. If you used wire mesh instead of wire, tie the plants at the same heights listed. If you planted along a fence or wall, adapt this tying method to help them cling to the surface.
Cut the canes that produced fruit down to the ground. Also cut any withered or diseased-looking canes. Compost non-diseased canes for next season.
Bird netting is most effective when installed 2-3 weeks before the berries are ready to be harvested.
Always thoroughly wash berries from a plant that has been treated with fungicide. Use water with a fruit and veggie wash.
