Q.Growth of Lemon Tree Roots
I hope you can help. I am renovating my house and have taken up the backyard tiles and intend to retile the area. My neighbor has a lemon tree planted right up against the adjoining yard wall. We found roots, which came into our side and ran along the property and later under the property, theirs and ours. We have cut the root back to the wall and want to make certain that it does not regrow. What is your advice please?

Make a cut into the root and paint the fresh cut with undiluted Round-up. The fresh cut will cause the plant to pull the Round-up into its system and will kill it. You may need to repeat 2-3 times if the roots grow deep, but it will work.
