Hi. I took some offshoots from a tree that was being felled for road widening... I have kept them in water since February.. They are about a foot long.. They had very small buds on when first picked.. One off the buds have now just started to leaf. It is right near the top. There are no roots at the bottom in the water.. I would love to carry on to grow this if possible, but don't know how to... Thanks.
