bamboo yellow leaves new culms dying
We have had dulce timber bamboo and a smaller bamboo version in a huge wooden box. For the last two years it has done wonderful. This spring the leaves on every plant are turning yellow and the new culms are coming up and then dying. They get about three feet or less and just start to shrivel up....we have done nothing different than in the past....what do we do. We are not over watering, or under watering. We put miracle grow on it for the fertilizer and still the whole thing is dying. There are not bugs or mold. Help it was an expensive box to set up and is beautiful, we hate to loose it.
