How can I remove invasive species (primarily bush honeysuckle) in order to prepare land for crop and orchard production?
Answer: Though bush honeysuckle is very invasive, it’s generally only difficult to eliminate from a “natural” environment. In a cropping environment, where bushes are repeatedly mowed, grazed, plowed, etc., they generally don’t last long. The key is simply knocking the top growth back to exhaust energy reserves in the roots. You can accomplish this with grazing by goats or sheep (they love honeysuckle, and it is nutritious), burning, brush-hogging, dozing, or even heavy applications of horticultural oil. Though all these methods will result in some grow-back, simply do it again once or twice more, and you will probably have eliminated the problem. You can always pull them out with chains and tractor power, but doing so is often unnecessary.For more information, you should find two ATTRA publications helpful.
