Next year all the bamboo was still dead. However, the following year the patch

that the bamboo was gone. At the Fall conference of the Maryland Native Plant

bamboo patches we have cut down this year with pokeweed. We can go out soon to
the open space habitats where we are controlling bamboo and identify which ones
have pokeweed? Then we can treat half of the patches but leave the other half
alone and see if resurgent pokeweed outcompetes the bamboo. The bamboo

issue is how open the bamboo habitat needs to be for the poke weed to
work.</FONT></STRONG></FONT></SPAN><BR><BR><BR><BR></FONT><STRONG><FONT

contact?<BR><BR>Hi Marc,<BR><BR><BR>After I sprayed the bamboo we planted trees
and then noticed a resurgence of pokeweed which I know is weedy. So I just left
it alone and it actually inhibited the bamboo from massively regrowing. I know I
just have to control (with machetes) of the shoots that have made it to grow
tall.<BR><BR><BR>In some cases nature can help you if you know how to play with

try this as an experiment in the Spring for any that survive the spraying.
Jorge, would you like to describe and share this poke weed
project?<BR><BR><BR><BR>Marc Imlay, PhD,<BR>Conservation biologist, Park Ranger
