Shop for bare-root plants now. If you can’t find what you want, ask your nursery to order from a grower.
Store bare-root plants in moist newspaper until you are ready to plant; submerge the roots in a bucket of water the night before planting.
Amend the soil with compost, then dig a planting hole that’s wide enough for the roots to spread out evenly. Spacing varies by variety, so consult the plant tags; avoid overcrowding.
Berries appreciate some afternoon shade. Give them all regular water.
