Blueberries rooting?
What is the best way to root blueberry cuttings?
I have looked up some information online but am having trouble finding specifics- I am trying the method using root stimulator and a tubering method but here are some things I would like to know-
what should i look for when choosing the cuttings to use- should there be certain characteristics or certain parts of the cuttings that I should be using?
How long should it take, how long should I give it and at what point should I give up if there are no roots?
What works best root stimulator and planting them vertically in sandy soil or tubering?
What is the best environment for propegating new plants?
Any experience you can share is greatly welcome and appreciated.
I have 7 viable blueberry bushes in my yard- three are fully mature and 4 are newbies and will probably not produce for about 2 more years
the cuttings I have are from my mature bushes- I just want to know how to make sure I use cuttings that have the capacity to root and how best to ensure rooting.

There are several methods of blueberry propagation, hardwood cuttings can be taken during winter before bud break and stratified in the refrigerator until mid-spring. Take whip cuttings 4-8 inches long, about as thick as a pencil. These cuttings should be from the new growth that the plant has sent off. They should be planted in a fine, acidic peaty soil, with sand or perlite. They should be planted upright, after being dipped in a commercial rooting hormone to stimulate buds to produce roots, the brand is not important, they are all the same. Depending on the severity of your summer, plants should be misted intermittently, and have partial shade. Rooting may take occur quickly or slowly, plants could be put into the ground the following year normally. If the plants do not root, you will be able to tell, they will turn brown, leaves will drop, and they will look dead. Softwood cuttings can also be taken in much the same fashion throughout the year. Rooting blueberries is not easy, so expect varied success rates. Sometime we can attain 85%, sometimes 10%.
