We get questions about trees all the time. Two of the most frequent questions we get are why do roots of the tree grow above the ground and up out of the lawn. The reason that they grow up above ground is to make sure they have enough oxygen and that's where the water is. The first thing we can do is manage our trees with water to try to force those roots down into the soil. So what we do is we water less often with more water. Once those roots have grown above ground we really can't do a lot about them. We have a girdled here that we're actually going to get rid of. But once they're above ground we can't do a lot about that. The second one is what do you do about suckers that are growing into our lawn and out of the ground? We can mow them out. We can deal with them and just let them grow. Or we can clip them out and use a hormone to restrict growth for that year. Since this is a chemical I'll put some gloves on and some glasses on to protect me. But this is a ready for use chemical. What we'll do is we'll come in and we'll cut this sucker off as close to the ground as we can and then we're going to treat it with this plant and hormone. That will take care of growth for this year. We'll have to do it again next year to any suckers that start in the lawn. This is Hudson Hill University of Wyoming Extension.
