(upbeat music) – [John White] Hello, I’m John White. Today we’re gonna talk
about some plant problems that we’ve been seeing and
been getting some calls on. And one is that we’re starting to see a lot of yellowing of
plants, including lawns. A lot of this is an iron deficiency. And this yellowing of the grass here is an iron deficiency that’s
showing up in the grass. And if you look at the
leaf blade real real close, you can see some green veins and on grass, the veins of course,
run parallel with the leaf. So, if you look at them real closely, you can see the chlorosis
between the veins and that’s a sign of iron deficiency. So, the way to correct this
is the use of a fertilizer that does have a iron content in it and it will help to clear it up. You can also use some of the foliar iron so that you can just mix those up according to the directions, spray them onto the grass area, let them sit for a period of time, maybe a hour or so, and then
go ahead and water them in. It should bring it up very quick. The granular materials
might take a week or so. Whereas the foliar, should green
it up within a day or two. So that’s one of the things we’re seeing. Be careful with the iron products. It does stain concrete
and white backgrounds. So be real careful. Maybe do a test spot
first and that should help to green it up. So that’s one of our problems. Let’s go take a look at another. Another problem we’re having is weeds and weeds growing where
you don’t want them. And one that’s very common in
the southern part of the state is Bermuda Grass. And if it’s in a lawn situation it’s good, but if it’s not in the
lawn, then it’s a weed, and it’s a troublesome weed. It’s very, very invasive. And some of the products
that we do have available for control of Bermuda
Grass is Grass-B-Gon and Round Up. So these two products,
they’re also available in other trade names. So we’re not endorsing any
particular product here, but these are a couple
of the products out here. Finale is another product
that you can find. Finale is strictly a
contact killer, top killer. It does not go down to the roots despite what it might
even claim on the thing, on the label. So what we wanna do is
use this in a situation where we are afraid of damaging anything where it might translocate to roots of Bermuda that may be in the lawn area. So if you want to keep an area clean, you can use this without much damage. So in a situation like this, where we have Bermuda
growing up between brick in a walkway, in a sidewalk, a driveway, a lot of times what we see on top is just a small indication
of what is underneath. So the root system on
this grass can actually be quite a ways underneath it. So, keeping as much foliage
as possible on the surface and getting it adequately
sprayed to the full length of the grass that’s available so that it’s absorbed through
all the different sites is the best way to kill this out. It may take some repeated sprays. But again, let the foliage grow out a ways so that you have more absorptive area and you’ll get a much
better kill on it again. And the Round Up is deactivated
when it comes in contact with the soil particles. It’s bound very tightly
so you don’t have to worry about it moving offsite. Go ahead and let it air dry and it’ll be fine. So that’s one way to control
some of your problems. In cracks and crevices,
don’t just chop it off, ’cause it regrows. Now we’re gonna be
talking about fire ants. And this is a problem that there have been some isolated spots where the actual imported
red fire ant has been found. Luckily those sites are very far and few, but we do have what we
call a native fire ant and this is called the Southern Fire Ant. This is one that has shown up in the area. And as we’re starting to
get a little bit more rain in the area, and as we get more moisture, sometimes these mounds will show up and be of interest to people. But also, they can be of a
danger to a young child or maybe young pets, so
you want to be careful. As we see here, we have a mound of soil that looks fairly docile and doesn’t seem to be much of a problem, but this is the way the
fire ant protects itself. It stays underneath the mound, and when the mound is disturbed is when the ants come up. Of course, I can’t bring any up right now. You can see some ants are
starting to come up here. Not in a large number, which is good. But that’s what a fire
ant mound looks like. This one’s pretty hot so
they may be down pretty deep. What we want to do is
just take an ant poison and treat the mound area. You can see the ants are
starting to come out now after we disturbed it. But these are a fire ant. When they bite, they do
leave a little bit of a welt. And they usually come out
in fairly large numbers when they’ve been disturbed. So, you want to be careful of these as far as stepping into them or having a young child
put their foot on the mound and leave it there ’cause
they will crawl up on it and give you quite a few bites. If you have any kind of allergy to it, of course, that can cause some problems. So again, we like to
get these under control. There are several different
fire ant baits available. There are several that are a bait that you put around the base of it. The ants carry it in and take it into the nest. Again, read the labels on the products before you use them. Make sure they are the proper material. But, I wanted to show you what
a fire ant mound looks like so that you’ll be on the alert for it.
