Getting rid of privet
My husband and I bought a pre-civil war house with 10 acres of land, of which about 3 acres is yard with many old, and lovely, plantings. Unfortunately, the house was vacant for a number of years and the flower beds, containing heirloom roses, bearded Iris, daffodils, etc. are also overgrown with vetch, privet, and honeysuckle. The vetch and honeysuckle I can deal with, but the privet is the bane of my existence. I'm scared to use Round Up or a similar herbicide because I don't want to kill the desirable plants. I've tried cutting the pivet back and "painting" the stumps with Round Up but they come right back. For the last couple of years, I've just cut the privet back to ground level but have to repeat this several times a year and the yard is too big (and I'm too old) to do this everywhere. Any advice on a permanent solution?
