Eliminate Different Weeds Before Planting Your Sod
Neil Sperry
DEAR NEIL: We have two kinds of weeds in our lawn. One is some type of ivy I can't seem to kill. It stays very low. The other grows tall and has thorns. You can pull on either of them and you'll get a runner that may be 2 feet long. Can I place sod over these as I start a new lawn, or what can I use to eliminate them?
I would try to eliminate them before planting the sod. The thorny plant sounds like smilax briar. It has glossy, heart-shaped leaves, often with silvery markings. Mowing alone will usually eliminate it. In those rare cases when it is so well established that mowing won't stop it, it's usually easiest just to hand-dig the big tuber and mass of roots around its crown.
As for the ivy, the same broadleafed weedkiller spray we mentioned earlier would work on it, but you need to apply it while the weed is growing most actively.
DEAR NEIL: Can I successfully dig and replant a climbing rose that we've had for 4 or 5 years? I need to put a walk around that side of my house now, and the rose is right in the way. When should I do it?
You can certainly move a climbing rose, and early February is the best time to do so. However, transplant it as you would an established shrub, that is, by digging a ball of soil around its roots. Use a sharpshooter spade for the digging. You'll probably want a soil ball that is 16 to 18 inches in diameter for a plant of that age. Cut the top back to about 3 feet before you start the digging.
That will compensate for the roots you'll be severing. It will mean that your rose won't bloom next spring, but it will help it survive the digging.
DEAR NEIL: A county agent told me years ago that I could eliminate clover by applying ammonium sulfate fertilizer (20-0-0) to the lawn while the clover leaves are moist with dew or irrigation. It would soon kill the clover, but the grass would not be harmed. Thought you might want to know.
I learned the same thing from my own father. He was in charge of herbicide research for Texas A&M, and we did that to eliminate clover in our lawn in College Station when I was a teenager. However, that was a long time ago, and the modern broadleafed weedkillers are far more dependable now. Those fast-release nitrogen fertilizers are damaging to turfgrasses in that they cause excessive bursts of growth and can lead to thatch accumulations.
