Don’t Sweat to Maintain Your Summer Landscape
Discover the easy summer landscape care system that keeps your yard healthy, colorful, and thriving all season long.
Summer can be brutal on landscapes. One week you’re admiring lush green lawns and colorful flower beds from all of the spring rain. The next week, a stretch of hot weather leaves plants drooping, grass turning brown, and weeds becoming more energized overnight.
After a few decades as a landscape architect, I’ve noticed that homeowners often make summer landscape care much more complicated than it needs to be. Many people assume that keeping a yard looking great requires applying tons of water, constant fertilizing, and spending every weekend pulling weeds.
The reality is much simpler.
The healthiest landscapes usually follow a few basic principles consistently. That’s why I like to think of summer landscape care as a simple 1-2-3 system:
- Water Wisely
- Protect from Stress
- Feed and Maintain
Follow these three steps, and you’ll be well on your way to an awesome yard that stays attractive during the hottest and driest part of summer.
Step 1: Water Wisely, Not More Often
If there is one thing that causes more landscape problems during summer than almost anything else, it’s improper watering. Many homeowners assume that if a plant looks weakened, the answer is always more water. Surprisingly, that’s often not the case.
Why Overwatering Creates Problems
Plants need oxygen just like they need water. When soil remains saturated for long periods, roots are unable to breathe, which can lead to weak root systems, fungal diseases, and unhealthy plants.
I once worked with a homeowner who insisted on watering his lawn every day during July because he had always done it that way. Despite all that water, the lawn looked terrible. The grass was thin, disease problems were appearing on other plants, and the soil felt constantly soggy.
He had sandy soil so we reduced watering frequency and switched to deeper irrigation sessions just two times each week. Within a month, the lawn and other plants looked significantly healthier. Sometimes less really is more.
Water Deeply and Infrequently
Deep watering encourages roots to grow downward into the soil where moisture remains available during droughty periods.
Shallow daily watering allows roots to stay near the surface. When temperatures climb into the 90s, those shallow roots dry out quickly. You want plant roots to work to access water and not be lazy and susceptible to weather extremes.
As a rule:
- Water early in the morning.
- Water deeply rather than frequently.
- Allow the soil surface to dry slightly between watering cycles.
- Adjust irrigation based on rainfall and temperature.
Morning watering is especially important because it minimizes evaporation and allows foliage to dry quickly, reducing disease pressure.
Signs Your Landscape Needs Water
Many homeowners wait until plants are severely wilted before watering. By that point, stress has already occurred and in some cases, permanent damage.
Watch for:
- Wilting leaves during morning hours
- Curling leaf edges
- Footprints remaining visible in turf
- Dry soil beneath mulch
- Slower plant growth
You can avoid getting to the point where your landscape needs water by simply checking. Make a habit of checking your planting beds weekly during the summer. Feel underneath the mulch and if it’s cool and moist there’s no need to water. If it’s warm and dry under the mulch, water slowly and deeply. Like my old mentor used to say, “Use your water meter”, as he would hold up a single finger. Learning to recognize these early warning signs saves a lot of headaches later.
Step 2: Protect Your Landscape from Summer Stress
Summer heat affects landscapes in many ways besides drying them out. Plants are constantly dealing with high temperatures, intense sunlight, wind, insects, diseases, and competition from weeds.
Fortunately, a few simple practices can dramatically reduce stress.
Mulch Is Your Landscape's Secret Weapon
If I could recommend only one summer landscape improvement, it would be proper mulch application.
Natural mulch acts like insulation for the soil.
It helps:
- Retaining moisture
- Moderate soil temperatures
- Reduce weed growth
- Improve soil quality over time
- Create a cleaner appearance
A two-to-three-inch layer of organic mulch helps steady soil conditions and protects plant roots from extreme temperature fluctuations.
Mulch is very effective when used properly, just don’t pile mulch over the stems of shrubs and against tree trunks. Something I remember being trained not to do when I was a teen working on a maintenance crew is “mulch volcanoes”. They continue to cause unnecessary damage to trees and shrubs throughout the country.
Stay Ahead of Weeds
Weeds are opportunists; they grow aggressively during summer and compete directly with your landscape plants for water, nutrients, and sunlight.
The key to controlling them is consistency. Spending ten to fifteen minutes each week removing young, shallow rooted weeds is far easier than spending an entire Saturday battling a jungle of mature, deeply rooted, woody weeds.
One of the biggest mistakes I see homeowners make is waiting until weeds become established before acting. It’s all too common for a homeowner to see a few sprigs of grass popping up in their planting bed one day, just to let them turn into a small patch the following week, which then turns into a bed of established turf by the end of a growing season. Weeds rarely improve with age.
Monitor for Pests and Diseases
Summer is prime time for many landscape pests and diseases. The earlier you spot problems, the easier they are to manage.
Look for:
- Chewed leaves
- Yellowing foliage
- Spots on leaves
- Premature leaf drop
- Distorted growth
- Branch dieback
A quick weekly walk through your landscape can often reveal issues before they become severe. A walk through the garden can also be therapeutic for a homeowner. Think of it as a wellness checkup for your yard.
Don't Forget Container Gardens
Container plants often require extra attention during summer. Unlike plants growing in the ground, containers have limited soil volume. That means they have the potential to dry out much faster.
I’ve seen beautiful patio plantings go from thriving to struggling in just a few days during a heat wave. Check containers regularly and water as needed. In extreme heat, some containers may require daily watering, especially if they are growing in a coco coir based soil mix.
Step 3: Feed and Maintain for Continuous Growth
Summer isn’t just about survival. It’s also about maintaining healthy growth and thriving landscape throughout the season.
Fertilize Thoughtfully
Not every plant needs fertilizer during summer. In fact, excessive fertilization can sometimes create more problems than it solves. Other than annuals, I recommend that my clients don’t fertilize at all in the summer to avoid a flush of tender growth during the heat of summer. Tender young shoots in the summer is an invitation to aphids to come feast.
For most landscapes:
- Follow soil test recommendations.
- Avoid excessive nitrogen applications.
- Use organic, slow-release products when appropriate.
- Water thoroughly after fertilizing.
A balanced approach is almost always better than chasing rapid growth.
Avoid Major Pruning During Extreme Heat
Summer is not the time for intensive pruning. Removing large amounts of foliage exposes plants to additional stress and can increase water demand.
Instead, focus on:
- Removing dead branches
- Eliminating damaged growth
- Cutting out diseased material
Save major structural pruning for more appropriate seasons like late fall and winter whenever possible.
Proper Lawn Care Makes a Huge Difference
Many homeowners unintentionally stress their lawns by mowing too short. You might like the look, but short grass creates several problems:
- Increased moisture loss
- More weed pressure
- Greater heat stress
- Shallower root systems
- Yellowing out
Raise the mowing height during summer. Taller grass shades the soil, conserves moisture, and promotes stronger root development, which leads to a better-looking lawn in the summer.
Leave Grass Clippings Behind
One of the easiest lawn improvements costs nothing. If your lawn isn’t too long, leave the grass clippings on the lawn. Clippings return valuable nutrients to the soil and help reduce fertilizer requirements.
Modern mulching mowers make this process simple and effective.
Bonus Tips for an Even Better Summer Landscape
Once you’ve mastered the basic 1-2-3 approach, a few additional strategies can take your landscape to the next level.
Add More Shade
Shade can dramatically improve landscape performance during summer. Trees provide one of the best long-term investments for any property.
They are also effective at:
- Reducing heat stress
- Lowering cooling costs
- Improving outdoor comfort
- Increasing property value
Even small ornamental trees can make a noticeable difference over time.
Choose Plants That Want to Live Here
One lesson I’ve learned over the years is that the right plant in the right place avoids countless maintenance problems. Native plants and regionally adapted species generally require:
- Less water
- Less fertilizer
- Fewer pesticides
- Less maintenance overall
When plants are well suited to local conditions, they spend less energy surviving and more energy thriving.
Perform Weekly Landscape Walkthroughs
This may be the simplest yet most valuable tip in this article. Spend five minutes walking your property each week.
Look for:
- Wilting plants
- Pest problems
- Broken branches
- Weed outbreaks
- Irrigation issues
Most landscape problems start small. Finding them early can save significant time and money later.
Conclusion: Great Summer Landscapes Are Simpler Than You Think
Many homeowners assume that beautiful summer landscapes require endless work. In my experience, the opposite is usually true. Summer is the time to sit in the shade with a cool drink and admire the work you put in during the other seasons.
The best-looking landscapes are often maintained by people who focus on a few important practices and perform them consistently.
Remember the simple formula:
- Water Wisely
Give plants deep, thorough watering when needed.
- Protect from Stress
Use mulch, control weeds, and monitor for pests and diseases.
- Feed and Maintain
Support healthy growth through proper mowing, pruning, and feeding.
Follow these three steps throughout the summer, and you’ll spend less time fighting landscape problems and more time enjoying your yard. And honestly, that’s what a great landscape is supposed to do—make life outside more enjoyable, not create another full-time job.
