Q.Taking starts off blackberries
I have 3 blackberry bushes I got 2 months ago I would like to take as many starts as possible off. They have thorns; the type is prime ark. When should I do this? Can you tell me how to do it? Thank you

This will be a lot like rooting any plant cutting, with the exception of one detail... In nature, the tips of the canes will bend down, and where they touch the soil will root. You will have to mimic this by taking the cuttings, and rooting them upside down. That is, the tips down into the soil.
