This has been a terrible, dreadful year for stuff sprouting up where I don't want it.
When Spring arrived, I started seeing a certain sprout many places -- even in my pond! Eventually, I searched on the web and discovered that these were maple tree seedlings. They're easy to pull up when they're only 5" tall.
The bad part was, I had a few growing among my shrubs and didn't know it. They were already at least 3 feet tall. I could tell that it would be very difficult to dig them up, because they were in some difficult to reach places, or in beds with decorative rocks.
You don't want maple tree seedlings taking hold in your yard. Believe me. You don't want an unplanned tree in a spot where it is likely to spread its roots and do damage.
Nothing against maple trees, of course. The silver maple is very popular here, and I suppose that there might be a Japanese red maple around my area, throwing its seeds into the air.
I determined that the only reasonable thing to do would be to buy some strong Roundup. I haven't used any in years, but Monsanto does have a version that is strong enough to kill poison ivy or shrubs.
I got some, and sprayed it on carefully, taking care not to get it on the other shrubs. I've now got some dead maple trees, although it took about a week to see that they were truly dead.
I'm also having more difficulty with vines that grow in my yard. I've had to dig some of them up in the front yard. They tend to send out horizontal runners, but not too deep. My front yard has a huge live oak, so the grass does not take hold well at all. This gives invasive plants a good foothold.
Once in a while, you have to do something you don't want to. I'm going to tolerate the dichondra which has invaded parts of my lawn, because it's not too objectionable. However, I can't have maple trees coming up on my property.
