STARTING, FINALLY!!

Hello All, Yes it's always fun to do something that you have NO clues on how its to be done!!;) well thanks to this site and a couple of others, answers can usually be found!:cool:

I have 2 blackberry mothers, 1 is just over 5 feet tall and the other is a just over 3.5, here's my dumb question, can clones be a foot or taller? or is that to tall for a clone??

I know that I've waited to long and the plants could have been cloned before now but like I stated above "NO CLUES"! I now have these 3 huge mothers (3rd is durban poison) and am looking forward to cloning, but want to make sure to do it right! thanks.

here are some pics of the blackberry's, sorry for the poor pic quality.:(
