Blueberries
Cover your
blueberries with a thick layer of mulch --- approximately six inches --- to
help retain soil moisture throughout the winter and protect the roots from
fluctuations in temperature. Mulches such as bark, peat moss or pine needles will
add acidity to the soil, helping to maintain the pH level that blueberries
prefer. Straw or hay will also work. Manure and compost are not recommended.
Keep mulch around your blueberries year round to improve soil drainage and keep
down weeds. Winter mulch should be about six inches thick to provide adequate
protection from cold weather, while during the growing season a mulch level of
three to four inches is adequate.
Prune your
blueberry bushes late in the winter or early in the spring, when the plants are
still completely dormant. Use pruning shears to remove any diseased, weak or
spindly branches and any canes that are more than six years old. Blueberry
bushes should be pruned once a year to ensure good fruit production.
