Title: Is non-native cotoneaster poisonous to goats from Eureka CA
Answered by: Barbara Medford
QUESTION:
I have heard that cotoneaster is poisonous to goats and other animals. We are trying to get rid of it in our yard, but I was hoping we could use goats to eat it back. What are our options in removing it?ANSWER:
We should begin by saying that Cotoneaster is native to China and the Himalayas and, as such, will not appear in our Native Plant Database. The Lady Bird Johnson Wildflower Center is dedicated to the growth, propagation and protection of plants native to North America. We can provide you with some links that may help you discover if your existing plants are poisonous to goats. We can also suggest an alternate way to get rid of those plants, since that is apparently your intent. Begin by cutting down the existing plants, as close to the soil as you can get. Within 5 minutes, using a disposable sponge paintbrush, brush that exposed trunk surface with a wide-spectrum herbicide. Do not use a spray, and be very careful not to spill or otherwise disperse the herbicide, as you will kill things you did not intend to do. Getting the herbicide on there quickly will allow the substance to enter the plant roots before they heal themselves over for protection. You can repeat this on every plant that is big enough to cut back. and will probably have to do it several times. As sprouts come up, clip or mow them back to the ground. Those sprouts provide leaves to continue to nourish the roots-no sprouts and the roots will eventually die, but not easily. If you don't already own hungry goats, we don't recommend you acquire any.
