Orchard Grass

Description: resembles crabgrass, forms in patches, lighter colored “V-shaped” blades
Peak Season: Perennial (year-round)
Treatment: non-selective herbicide and replant

Orchardgrass consists of a dense tuft of basal leaves from low vegetative shoots. These lighter green leaves can grow up to 10″ long and 1/3″ wide.

When will I see orchardgrass?

Orchardgrass is a perennial, meaning it grows year round like your lawn. Similar to your lawn, it begins to grow again in early spring and begins to go to seed in May.

How do I get rid of orchardgrass?

Since orchardgrass is a grass, only a non-selective herbicide can kill it. The drawback to this is it will also kill your lawn in that area, so it will be necessary to reseed the affected area.d

How do I prevent orchardgrass from infiltrating my lawn?

While there is no way to perfectly keep out all Dandelions, there are a few things you can do to help prevent new growth in your lawn. These include:

  • A Pre-emergence herbicide in April or May to help prevent germination.
  • Mowing your lawn on the second highest setting to help crowd out any potential growth and block out the sunlight.

Morning Glory

Monday, May 4th, 2009

Description: Long green vines up to 10 feet long. Heart-shaped leaves with bell-shaped flowers
Peak Season: Perennial (year round) Most aggressive in late spring (May- June)
Treatment: Herbicide

Morning Glory is characterized by bell-shaped flowers that typically open from dawn till midmorning and close for the rest of the day. They can be a variety of colors from blue and purple to white. The vines can grow up to ten feet long in as short as two months, riddled with heart-shaped leaves.

When will I see Morning Glory?

Since Morning Glory is a perennial weed, you will see it year round. As is common with most plants, the primary growing is done during the late spring time (May – June).

How do I get rid of Morning Glory and how long will it take?

Aside from hand pulling the individual taproots out of your lawn by hand, a selective herbicide is the best way to get Morning Glory out of your lawn. This should be applied every five to six weeks. After the second consecutive application you will see withering in the leaves. I can take up to six consecutive applications to completely kill the largest and most established plants.

How do I prevent Morning Glory from getting into my lawn?

While there is no way to perfectly keep out all Morning Glory, there are a few things you can do to help prevent new growth in your lawn. These include:

  • A Pre-emergence herbicide in April or May to help prevent germination.
  • Mowing your lawn on the second highest setting to help crowd out any potential growth and block out the sunlight.

Mallow is one of the harder weeds to kill with a selective herbicide, but it can be done. Apply this every 5 to 6 weeks. You should start to see damage and withering to the leaves after the first or second application, with the plant completely killed after 6 consecutive applications. If you don’t want to wait for the whole summer, you may consider weeding them by hand.

The Dandelion

Description: Broadleaf weed with deep, fleshy taproot; yellow flowers.
Peak Season: April – May
Treatment: Herbicide

Dandelions are a perennial broadleaf weed. They are characterized by a deep, fleshy taproot, broad and jagged leaves, and yellow flowers up to two inches in diameter. As the flowers go to seed, the yellow pedals are replaced with white, puffy seeds. When wind blows they are then disbursed throughout the region.

When will I see Dandelions?

While Dandelions are seen throughout the year from early spring to late fall, they are most rampant during the spring. During this time you will see an aggressive expansion phase.

Clover

Monday, May 4th, 2009

Description: Green, shamrock-shaped leaves. White or pink ball-shaped flowers.
Peak Season: Late summer (July – August)
Treatment: Herbicide

Clover is known for its shamrock-shaped leaves which are relatively easy to pick out. They have white or pink, ball-shaped flowers which can attract bees, and in a lawn that you walk on, is not a good thing. The root system aggressively expands above and below ground all from a main taproot.

When will I see Clover?

Clover is a perennial weed, meaning it can live for years. Therefore, you may see it in your lawn throughout the year as long as there is no snow, peaking during July and August.

How do I get rid of Clover and how long will it take?

Clover is one of the harder weeds to kill with a selective herbicide, but it can be done. Apply this every 5 to 6 weeks. You should start to see damage and withering to the leaves after the first or second application, with the plant completely killed after 6 consecutive applications. If you don’t want to wait for the whole summer, you may consider weeding them by hand. This can be effective if you completely pull out the taproot.

How do I prevent Clover from infiltrating my lawn?

While there is no way to perfectly keep out all clover, there are a few things you can do to help prevent new growth in your lawn. These include:

  • A Pre-emergence herbicide in April or May to help prevent germination from new growth.
  • Mowing your lawn on the second highest setting to help crowd out any potential growth and block out the sunlight.
  • Since clover grows best in moist soil with low fertility levels, decrease the frequency of your watering and increase the depth, leaving the water down too low for emerging clover to take advantage of. It also helps to increase fertilization in all levels except phosphorous to make it a less hospitable growing place for clover.
