What to do to your Lawn in April & May!

“April & May are the best months to Aerate and a good time to put down a Spring Fertilizer.  If you activate your sprinkler system this time of year you are safe from things freezing in ground, however your backflow preventer could freeze up if temperatures fall below 32 degrees for an extended period of time.  To prevent this from happening and to enjoy the ease of using your system, just wrap the pipes on the side of the house with installation or even use a simple blanket and cover with a plastic bag to keep the cold edge off.  It is also a great time to Power Rake before your turf gets too green…call us to see if you could still benefit from a power rake & or fertilization.  Due to the extreme dry winter we have had, we are finding extreme cases of mites & spiders in turf areas.  If you have patches of brown that are not greening up or brown patches that are getting larger…you could possibly have spider mites eating away at your turf…Call us for an evaluation.”

Bugs to look for in Late April

Bugs to look for in Late April

Late April

Household Insects

Ants:  Foraging ants in homes are common until temperatures allow them to seek food outdoors.

Tree/Shrub Insects

Cooley spruce gall:  Insects continue development and usually begin to produce egg sack in late April.

Lilac/ash borer: Flights of adult moths may begin.

Poplar twiggall fly: Adults emerge and begin to lay eggs in emerging aspen shoots.

Spider mites on pines:  Populations may increase rapidly on ponderosa and other susceptible pines

Spiny elm caterpillar:  Small colonies of these caterpillars may be seen on willow, hackberry, aspen, elm and other trees.

Douglas-fir beetle:  In forested areas, adult emergence, flights and tree attacks may begin.

Brownheaded ash sawfly:  Adults may lay eggs during warm days following bud break.

Zimmerman pine moth:  Approximate treatment timing for overwintered larvae. 


Turfgrass mites:  Clover mites continue to feed on lawns and enter homes in nuisance migrations.

Nightcrawlers: Tunneling activities and associated lawn lumps continue.

Midges: Non-biting midges emerge from ponds and mating swarms may be observed over lawns.


Spinach leafminer: Egg laying and tunneling begins in older spinach foliage.

Quick Facts…

  • Ascochyta is a fungus that is usually just an aesthetic problem on Kentucky bluegrass lawns in Colorado.  It may also occur on tall fescue and perennial ryegrass.
  • Leaves usually start dying back from the tips & severe areas of affected turf will turn straw-colored however your turf is not dead.
  • Ascochyta can occur throughout the growing season, but is more prevalent in the spring when there are extended wet periods symptoms may develop throughout the growing season but are more common when cool rainy conditions are followed immediately by hot dry conditions. The overall appearance of the disease may resemble drought stress, except that the symptoms of Asochyta blight appear quickly (i.e. sometimes overnight).

Treatment for Ascochyta!

  • Reduce thatch and promote water penetration through the soil by aerating.
  • Sharpen blades & maintain grass height between 2 ½ and 3 inches. Avoid mowing during wet weather.
  • Although the fungus can be spread from one location to another on grass clippings it is unlikely to contribute significantly to disease development because the fungus is already present throughout every lawn.
  • Maintain a balanced fertilizationprogram.
  • Try to maintain uniform soil moisture. Check your sprinkler system to make sure all sprinkler heads are working properly and that water is being distributed uniformly to avoid drought stress. On the other hand excessive irrigation and poorly drained soils may also promote disease development.
  • The damage usually takes several weeks to disappear.
  • If you can’t wait, a fungicide can speed up the healing process especially on more severely damaged lawns…Call us for a free evaluation!

Bleached leaf tips and banding are characteristic of Ascochyta leaf blight.

Grub Worm

Quick Facts…

We see Grub damage way less often than other turf damages such as spider mites.

Grubs are a root-feeding immature (larval) stage of beetles, which include the following: Japanese beetle, European chafer, masked chafer, Oriental beetle, green June beetle and the Asiatic garden beetle.

The beetles lay their eggs 1 to 2 inches deep in the soil and the eggs hatch in 2 to 4 weeks.  The young grubs begin feeding on grass roots immediately.  They grow to full size within 3 to 4 weeks.  This is their most damaging time to the turf.  The grubs move deep in the soil for hibernation just before winter arrives.  They come back to the root zone and start eating again in the spring.

Around May, depending on your location, the grub transforms into pupae and a few weeks later they emerge as adult beetles.

Their most visible damage can be seen in the late summer months when the turf is most stressed.

Severe infestations may see numbers of up to 50 grubs per square foot.  Your turf will roll back like carpet & your lawn will yellow and die quickly.

Treatment for Grub Worms!

Usually grub worms are not that large in numbers to severely damage your lawn, so just let nature take its course.

If there are large numbers, insecticides may be necessary to control them. Applications should be done when they are close to the soil surface and before they have damaged the lawn.

Fairy Ring

Quick Facts…


Fairy rings are almost perfect 1ft to 12 ft circles that sprout in lawns after prolonged periods of wet weather, often in areas where dead organic matter has accumulated. Old tree roots, stumps or home construction debris, especially sawdust, encourage their growth.

Mushrooms may grow in a circle around grass, forming “fairy rings.” Grass inside these rings can be a darker green and grow more quickly. In some cases, there are so many mushrooms in these rings water cannot penetrate into the soil and the grass dries out, sometimes dying. This leaves a ring of dead, brown grass and another ring of darker green, healthy grass.

Treatment for Fairy Ring!

Fungicides don’t usually kill fairy ring mushrooms in this region but will sometimes help. Spring and fall aeration and several applications of a few ounces of dish washing solution in a gallon of water on the ring will sometimes make the ring less noticeable.


While there are many fungi that cause fairy rings, the presence of mushrooms in the lawn does not mean fairy rings will form. Most mushrooms that grow in lawns are feeding on dead organic matter which has accumulated in the lawn. The mushrooms can be mowed off or removed with a rake.

Lawn mushrooms may be poisonous or may cause allergic reactions and should not be eaten by humans or pets unless proper identification shows they are edible.

What to do to your lawn in July!

You should have fertilized your turf already for the 2nd time this season.  If you have not, you should still apply fertilizer at this time!  It is a huge mistake to water more often in the hotter days coming up.  It is better to water less often for a longer duration to get the roots to develop deeper into the soil so the turf can sustain the heat.  Use polymers such as a dish soap to help hold the water in the soil longer for a healthier turf.  If you have brown spots at this time look for rabbit droppings in those areas or have your sprinkler system tested for proper coverage.
