Did You Know You Have Help In Your Battle to Control Landscape Weeds?
It’s springtime in the Mid-Atlantic. The day time temperatures are warming up, you’re hearing birds everywhere singing their welcome to spring songs and there is one other thing that also seems to get a big kick in their step about this time, WEEDS.
When the air temperature warms, in turn, warming your soil, you will start noticing weeds coming up everywhere. Your once clean planting beds are now covered with little corn stalk looking green things popping out all over the place.
Even in your turf, that thick lush looking stand you thought you had, weed seeds are present, everywhere in the soil waiting to poke out their little heads to bask in the sunlight. When the soil warms, weeds germinate at the soil line under the canopy of your existing grass, going unnoticed until they have grown big enough to compete with the grass around them.
Mother Nature what were you thinking?
It seems like Mother Nature starts a battle every spring that keeps the weeds one step ahead of us never allowing us to catch up. The quantity of weeds seeds waiting to germinate at any given time in the soil around your house is uncountable. We pull six here, twenty pop out over there. You pull one here and as you remove this one, fifty seeds spring off the plant starting the cycle over again. A neat thing to watch but a real pain in the you know what.
Luckily, there are some products available that we can use to help control this massive population with relative ease. These are called pre-emergents and post-emergents.
What is a Pre-emergent?
A pre-emergent is a chemical formulation that when applied to a planting bed or turf area will prevent weeds from germinating or starting their life cycle. This chemical needs to be present at the soil line before the weeds start to grow.
When applied, the pre-emergent will form a barrier at the soil line and any new seedling that tries to grow through this barrier will be killed. Remember, pre-emergents will not kill existing weeds and these weeds will need to be sprayed with a post-emergent like round up to control these weeds.
Pre-emergents are usually applied in either a granular or liquid form.
Some of the common names of pre-emergents for bed care are Snapshot, Gallery and Surflan. Apply to your planting beds before you mulch, will last about 2-3 months
Some of the common names of pre-emergents for turf care are Dimension, Barricade and Pendamethylin. Apply to your lawn the first week of April
What is a post-emergent?
A post-emergent is a chemical formulation that is applied to actively growing weeds in planting beds or turf. These weeds are already above ground, actively growing and there is a need to eliminate them.
Most post- emergents are used in liquid form sprayed out of a sprayer.
Common post-emergent for bed care is Round-Up.
Common post-emergent for turf care are Three Way, Confront and Momentum.
What does Selective and Non-Selective herbicides mean?
Post-emergents are applied to weeds that are actively growing and they can be selective and non-selective.
There is a wide variety of different types of weeds and each one has its own chemical make up. Over the years, chemicals have been formulated to control these differences in each weed so we can eliminate one and keep another when necessary. This means we can be select what we want to eliminate
There are grassy weeds that look like grass but not the type of grass you want in your lawn (crab grass, annual blue grass, goose grass and foxtail).
There are broadleaf weeds where the leaves on the plant are wider than a blade of grass. (dandelion, chickweed and clover).
How do they work?
Selective herbicides are formulated to kill specific weeds and those weeds only. A selective herbicide for broadleaf weeds can be sprayed directly over your turf grass and it will kill only the broadleaf weeds that it comes in to contact with, not the grass.
Non-selective herbicides are formulated to kill anything that is growing. This means that they don’t care what they kill, they kill everything.
Round up is a non-selective herbicide and it will kill anything that it comes in contact with that is actively growing. Round up needs the plants to have leaves for the chemical to be sprayed onto so the chemical can get into the system of the plant. If the plant does not have leaves, round up will not work.
If you have weeds in your turf that you want to kill and you sprayed round up on this area, not only would the weeds die but also any grass around the weeds that came in contact with the spray.
Do not use round up in your turf for weeds unless you want to kill everything.
Once again, information is power and the right info can take you a long way in your battle against our number one landscape nemesis, the weed and all of his cousins.
Good luck, be proactive, read the labels and be safe.
Achieve your best landscape,
