Never grow bamboo. 20 years ago I planted bamboo at the house-.................edit................
(I tend to ignore statements that say "never"or always", because there are usually exceptions. But with bamboo........)
. That label should strike fear into any plant-person.
------ As a quick, pointless aside, when I first read the label on a contact cement can years ago, it said to apply the glue to both surfaces and then wait for them to become "aggressively tacky." I thought that was hilarious. Like Christmas sweaters or bad hairdos. But I digress....
Bamboo, kudzu, autumn olive, oriental bittersweet
. Those are some of the scary aggressively invasive plants where I live. They all spread by roots/rhizomes, and some also by berry seeds from bird droppings. They will all choke out the native plants that have been supporting the local wildlife for hundreds of years. The results are not good. Kudzu and autumn olive were both introduced with the best of intentions to stabilize the soil on hillside projects and reclaimed strip mining land. They definitely stabilized the soil, but then they "escaped" and took over wherever they went. The area I circled in the picture is an example of 2 seasons of growth from an area that was cleared of trees. Goats will help with keeping it under control, but you have to keep the goats under control, too.
CONTROLLING THE INVASIVES WITH HERBICIDES
Unfortunately, it takes herbicides to control these. No way can you remove the plants and get all of the roots.
Trichlopyr (Crossbow is one commercial name), mixed with about 4 parts diesel fuel, and then, either: 1) sprayed on the bottom 16" of each small trunk, 2) cut them down and then paint the stump within 5 minutes with the same mixture, 3) hack a notch or 2 in the bottom 16" of a larger trunk, and immediately squirt the trichlopyr mixture into the hack-marks. These 3 methods with trichlopyr work in the dormant season, also. Glyphosate (Round-up) is much less effective and only works when the plants are actively growing. In my experience on these super aggressives, the Trichlopyr seems to be about 80% effective and the glyphosate is 50%.
