Every summer, we hear from homeowners doing their best to keep their lawns green, thick, and healthy through the heat. The instinct to protect your turf during hot, dry weather is a good one, but it’s easy to fall into habits that seem helpful on the surface but can actually cause long-term damage.
Things like watering every day, mowing too short, or over-applying fertilizer might look like proactive care, but in many cases, these practices create shallow root systems, invite pests or disease, or put unnecessary stress on the lawn when it’s already dealing with heat and drought.
At Aspen Tree and Turf, we understand that good lawn care starts with good information. With that in mind, we’re breaking down some of the most common summer lawn myths we hear from our clients, and sharing what your grass really needs during the hottest part of the year.
Myth #1: “Watering every day keeps the lawn green.”
It’s tempting to think more water equals a healthier lawn, especially when temperatures climb. However, frequent, shallow watering encourages grass roots to stay near the surface, where they’re more vulnerable to heat and drought.
What your lawn really needs:
Less frequent, deeper watering. This encourages roots to grow deeper into the soil, where they have better access to moisture and nutrients. Most established lawns do best with about an inch and a half of water per week, ideally delivered early in the morning.
Myth #2: “The more fertilizer, the better.”
Fertilizer can give grass a boost, but too much—especially in hot weather—can burn your lawn or cause excessive growth that weakens the root system.
Our approach:
We tailor fertilization to the time of year, current weather, and the specific needs of your lawn. Mid-summer is a time to be cautious, not heavy-handed.
Myth #3: “If it's green, it's healthy.”
A lawn can look green while still struggling with underlying issues like soil compaction, disease, or pest activity. Certain weeds also mimic turfgrass in color, tricking the eye into thinking everything’s fine.
What to watch for:
Thinning patches, off-color spots, and irregular growth patterns are all signs something may be off. Our technicians are trained to catch these subtle cues and respond before things get worse.
Myth #4: “Cutting the grass shorter means mowing less often.”
It might seem efficient to mow low and stretch the time between cuts, but that approach actually weakens your lawn. Short grass exposes the soil to sun, dries it out faster, and stresses the turf, making it more susceptible to weeds and heat damage.
A better approach to summer mowing includes:
- Mowing once or twice a week, depending on growth rate.
- Setting your mower height to 3 to 3.5 inches.
- Never cutting off more than one-third of the grass blade at a time.
- Leaving clippings on the lawn to return nutrients back into the soil.
- Always mowing with a sharp blade for a clean, healthy cut.
These small adjustments can make a big difference in the overall appearance and resilience of your lawn throughout the summer.
