Growing blueberry plants from cuttings is a quick and easy way to get new bushes. Cuttings can be done from both hardwood and softwood, but hardwood cuttings tend to be easier to work with and more likely to root properly.
Hardwood cuttings are best taken in the late winter or early spring, before the leaf buds begin to open. Choose shoots that are about the diameter or a pencil and have no side branches growing from them.
To prepare your shoots, remove all fruit buds. Leave the leaf buds. (The fruit buds are the fatter of the two.) Trim the shoots to 4-6 inches. Make sure your leaf buds are pointing upward, then strip the bark on the lower ½ inch to inch of the shoot to help with rooting. You will want to plant them in a mixture of half peat moss and half either sand or perlite.
Bury each shoot about half way. If you have multiple shoots, keep them 2 or 3 inches apart. Water right away, then again weekly. You need to keep your cuttings in full sun and keep the soil temperature around 70 degrees. In 3-4 months, you can expect to see leaves sprouting and the roots should be ready for transplant in about another month. Plant them 3-5 feet apart.
Blueberries love acidic soil. Coffee grounds or a mixture of 1 tablespoon of white vinegar to 1 gallon of water makes a great fertilizer.
