Wolbert's Inc BBB Business Review


“Why is my lawn turning brown? Wolbert's is fertilizing and my irrigation system is running, so what’s the problem?”

We are seeing a lot of this
Typical moisture stress

The problem is the soil is dry in the brown spots and the grass is going dormant as a result.  No irrigation method is perfect whether it be an automatic system or hose a sprinkler. Without rainfall, areas where coverage is poor will be the first to turn brown. Thatch and compact soils can exacerbate the problem. Irrigation system repair and adjustment is imperative to correct the stressed condition.

With WaterMax treatments, followed by proper watering, water will move rapidly to the soil. When the soil is moist, new blades will grow again and the lawn will green up.

Recovery time is significantly faster with WaterMax treatments.

Watering Tips

Using a water gauge, or any flat bottomed container, is the sure way to know how much water your system is delivering, and how even the sprinkler coverage is.

Turf quality is directly linked to available moisture in the root zone (up to 12” deep). Improper watering is the main reason for dry, brown patches in lawns. As a rule, one inch of water each week is adequate for healthy turf. Rocky or sandy soil conditions may require a bit more, but usually 1/2 inch of water every 3-4 days is adequate, as long as the soil stays moist.

Individual sprinkler spacing and coverage may deliver differing amounts in the same amount of run time. It’s a simple process to determine water output by using the water gauge provided today, or any flat bottom, straight sided container. Place the gauge or container under the sprinkler pattern and record how long it takes to collect 1/2 inch of water. For instance, if it takes an hour to collect 1/2 inch, set your irrigation to run an hour every 3 or 4 days, and you should be supplying adequate water for healthy turf. If you don’t measure the water output, it becomes a guessing game; if you’re wrong, drought stress may occur.

To check for drought stress, use a small shovel or hand trowel to expose a few inches of soil in a brown area, and compare it to the soil in a green area. If the soil is dry in the brown spots, and moist in the green areas, check the sprinkler coverage, as it may need adjustment or repair. As with aeration/dethatching, we have recommendations for irrigation specialists who can help.

As mentioned already, it’s best to water infrequently, and deeply. The key is
to keep the soil moist for optimal uptake by the roots. Infrequent watering encourages surface drying between watering days, minimizing fungus potential. Watering in the early morning is recommended, so the grass dries before nightfall. In addition, water pressure is usually better in the early hours, the dew is reclaimed, and the winds are usually calm. Evening and night watering may invite fungus problems. But, if it’s the only time you can water, please do so!

Our last couple of hot, dry summers have given rise to an often overlooked, but damaging pest on Pieris Andromeda shrubs. These plants, like most types of azalea (also a target for lace bugs), prefer a partially shaded environment, away from hot afternoon sun. When exposed to excessive heat and sunlight, they become prone to […]
