Choose a location that gets plenty of sun. It should also have a trellis behind it, or you can add one made of wood, wire or other sturdy material. These bushes must be supported in order to grow properly.
Prune the canes down until they are about 6 inches tall before you plant them. This will help the plant get a good start.
Dig a hole large enough to hold the olallieberry’s root ball with about 3 extra inches around it and under it. Take all of the soil out of the hole.
Mix the soil with aged compost, using about half soil and half compost. Break up any large lumps. Be sure the compost is well aged so that it doesn’t burn the plant’s roots.
Put a layer of the soil and compost mixture into the hole so that it supports the olallieberry at the same depth it was at in its nursery planter. Test the plant to make sure, and if necessary remove it and adjust the soil until you have it correct. If you plant it too deep the stem is likely to rot, and if it is too shallow the roots may dry out or encounter disease and insect damage.
Fill in around the roots with the soil and compost mixture. Pat it down firmly so that it supports the plant, and also so that there are no air pockets around the roots.
Tie the canes to the trellis as they grow with soft cotton string. Tie the verticals in an upright position, and support all lateral growth horizontally.
