Turf Fertilization
Pest and Disease Control

Ninety-five percent of yard and garden visitors are harmless and some are even helpful with eating other insects, breaking down organic matter and pollinating flowers. However, that remaining 5% can cause great damage if left unchecked. If your plant life is ailing Garpiel Group can help determine what can be done to manage pests and disease in your outdoor spaces. Here are some known destructive culprits in the Great Lakes Bay Region:

Turf Fungi Can Be Controlled

When we experience frequent, heavy rain that causes slow-release fertilizers to break down faster than normal. The rain flushes out the nutrients faster than normal, leaving plants susceptible to damage, including turf fungi. In this part of Michigan, the most common turf fungi we see are Red Thread, Dollar Spot, Summer Patch, and Necrotic Ring Spot. If you think one of these has infected your lawn, Garpiel can recommend cultural control methods that may help.

Snow Mold

After the snow melts, you may find that your lawn is riddled with circles or patches of dead-looking grass. It will look gray, tan, white or even pink. While it could be that the grass is dead because of the extreme winter conditions, you likely have one of two kinds of snow molds: gray or pink. These diseases are related to the length of time your turf is snow covered (usually three or more months). A heavier thatch layer also promotes snow mold.

European Chafer Grub

To most people, a grub is a grub. If you’ve seen one, you’ve seen them all. In the state of Michigan, there are two varieties of grubs that we most commonly see: the Japanese beetle and European chafer. The European chafer may be the most serious grub pest of home lawns. Although not as wide spread as the Japanese beetle, the European chafer is more damaging to your turf in areas where both are found. Unlike the Japanese beetle, the European chafer is not a problem in daily irrigated turf.

New Strategy for combating crabgrass

Large and smooth crabgrass, a summer annual that germinates in the spring, is often considered to be the most problematic weed in turf. When soil temperatures reach a consistent 55 degrees, conditions are most favorable for germination. Crabgrass can continue to germinate throughout the summer until August. One square foot of crabgrass can produce at least 10,000 seeds.

The dandelion is a common perennial broadleaf member of the daisy family with a thick, deeply penetrating taproot that is found in lawns and other open turfgrass areas. They grow directly from the crown of the plant with no stem, forming a rossette at the soil surface. It is distinguished by its yellow flower, hollow stem that secretes a milky juice when broken and tufted seeds.

Crabgrass is the most commonly found grassy weed in Michigan lawns. Crabgrass grows vigorously in full sunlight and high temperatures and will easily out compete cool-season grass under those conditions. The most notable areas in your turf would be along the driveway, sidewalks and rubber edging. Crabgrass is a summer annual. This plant has a life cycle of less than one year.
