Hello. Here in Vancouver I got from one of my neighbors black bamboo from 4-5 feet tall to 15 feet tall (some are about 3/4 of an inch wide) some branches have leaves 1/4 up only other are full with leaves. It took me 4 hrs to dug them out . I got root balls with many little feeders . I replanted all of them within 24 hours and kept the roots in a pot with wet earth while waiting . The 1st evening they looks 100% alright but today all the leaves seem to dry out. I had to cut dig them out with a steel shovel as it had grown under a concrete path. it was VERY knotted. I have divided it all and replanted in big strong plastic containers ( black plastic ex paint containers 100% cleaned with 12 drill holes in the bottom and two inside strong PVC pipes that are standing vertically in extremely fragile African clay pots. The roots could brake the pot after a few years. I brought them from Tanzania I can't risk that. I replanted all of them within 24 hours and kept the roots in a pot with wet earth while waiting the replanting. The 1st evening they looks 100% alright but today all the leaves seem to dry out. I understand there must be some stress BUT I would like to know from the experts out here . Will it survive the move or not I did not want to make all this work for nothing. I have transplanted black bamboo in South Africa no problem...I understand Canada is not South Africa BUT they were VERY HAPPY at my neighbor and growing wild and multiplying like a forest as he did not have them containers.
