Whether you are replanting your blueberry bushes for relocation or establishing a patch transplanted from nursery containers, careful preparation of the soil and planting technique is of paramount importance. Blueberry plants can produce fruit over a long life of up to and beyond 25 years. Careful replanting will protect your investment and ensure the plants long term health and performance. Replant your bare root blueberry bushes in the late winter or early spring and your balled and burlapped or container grown plants in the fall for best acclimation in the soil.
Dig a planting hole in a full sun location that is twice the diameter of the root mass and at least as deep as the root mass when the roots are spread naturally. Loosen the excavated soil with your shovel and rake to make it light and friable.
Amend the planting soil with aluminum sulfate to create an acidic soil with a pH hovering right around 5.5 pH. Follow the package dosing directions and work the amendment into the soil with a shovel. Commission a soil test if you are in any doubt about the acidity or alkalinity of the soil.
Amend the planting hole and excavated soil with several pounds of organic matter so that roughly 3 percent of the soil is made up of enriched organics. Use a combination of aged livestock manure, compost, peat moss, sawdust or wood shavings. Line the planting hole and work the balance of the organics into the excavated soil with your rake or shovel.
Set the blueberry plants into the planting hole so that the top of the root mass sits level or just very slightly proud of the surrounding soil. Back fill the amended soil around the root mass tamping down lightly to make good contact with the roots.
Water the blueberries deeply after replanting so that the root mass and surrounding soil is drenched but there is not standing water.
Mulch with shredded bark, leaf mold or pine needles or another organic material in a 2 to 3-inch thick blanket. Replenish the mulch each year as it degrades into the soil to keep weeds at bay, hold moisture in the soil and protect the blueberry roots from temperature fluctuation.
