Q: I have a weed with flowers along the stem which grows in my flower bed in late summer. How do I get rid of it?
A: The most common fall weed I see is mulberry weed, so named due to a slight resemblance of its leaves to those of a mulberry tree. It is the very devil to get rid of. Each plant can have hundreds of seeds and they seem to have a 110% germination rate. The weed can be prevented with a pre-emergent but it grows so vigorously in places where flowers self-seed that this may not be practical. Personally, I use a non-selective organic spray to kill it whenever it shows itself. I prefer not to use glyphosate (Roundup, etc) because the weed is so often snuggled close to my garden plants and I don’t want to risk hitting a good plant with a chemical that can travel from the affected leaf site to the rest of the plant. With rigorous attention to pulling it out, I have less mulberry weed now than three years ago but it still pops up more than I’d like.
