Top 10 Landscaping Mistakes Homeowners Make (and How to Avoid Them)

Creating a beautiful landscape is one of the best ways to improve your home's curb appeal and increase its value. But even with the best intentions, many homeowners make common landscaping mistakes that can lead to unnecessary maintenance, poor plant health, drainage issues, and wasted money.

The good news? Most of these mistakes are easy to avoid with a little planning and the right landscaping materials.

Here are the 10 most common landscaping mistakes homeowners make—and how you can avoid them.


1. Choosing the Wrong Mulch

Not all mulch is created equal. Using low-quality mulch or applying the wrong type can lead to faster fading, weed growth, and poor moisture retention.

Avoid It By:

  • Choosing premium hardwood mulch or colored mulch for long-lasting appearance
  • Applying mulch 2–3 inches deep
  • Refreshing mulch annually instead of piling on new layers every year

Pro Tip: Bulk mulch is often more cost-effective than buying dozens of bags, especially for larger landscaping projects.


2. Using Too Much Decorative Stone

Decorative stone is beautiful and low maintenance, but covering every landscape bed with stone isn't always the best solution.

Too much stone can:

  • Absorb excessive heat during summer
  • Make future landscape changes difficult
  • Increase soil temperatures around sensitive plants

Avoid It By:

Use decorative stone where it provides the greatest benefit, such as:

  • Foundation beds
  • Walkways
  • Drainage areas
  • Around hardscapes

Mixing mulch and decorative stone often creates a more balanced, attractive landscape.


3. Ignoring Drainage Problems

Poor drainage is one of the most expensive landscaping mistakes homeowners can make.

Standing water can damage:

  • Lawns
  • Plant roots
  • Foundations
  • Walkways

Avoid It By:

Install the proper aggregate, gravel, or drainage stone beneath problem areas and ensure water flows away from your home's foundation.

Address drainage issues before adding decorative landscaping.


4. Planting Too Close Together

New plants often look small at the garden center, but they'll continue growing for years.

Crowded plants can lead to:

  • Poor air circulation
  • Increased disease
  • Constant pruning
  • Overgrown landscaping

Avoid It By:

Always plant based on the mature size—not the size of the plant when you buy it.

A little extra space today creates a healthier landscape tomorrow.


5. Choosing Materials That Don't Match Your Home

Landscaping should complement your home's architecture—not compete with it.

For example:

  • Modern homes pair well with gray, black, and white decorative stone.
  • Traditional homes often look best with natural river rock or earth-tone stone.
  • Rustic homes typically benefit from larger natural stone and warm colors.

Choosing materials that match your home's style creates a cohesive appearance and boosts curb appeal.


6. Forgetting Landscape Edging

Without edging, mulch and decorative stone gradually spread into the lawn, creating messy borders.

Avoid It By:

Install quality edging around:

  • Landscape beds
  • Trees
  • Walkways
  • Decorative stone areas

Edging creates clean lines and dramatically reduces maintenance.


7. Buying Too Little Material

Few things are more frustrating than running out of mulch or decorative stone halfway through a project.

Avoid It By:

Measure your project carefully before ordering.

Many landscape suppliers can help estimate:

  • Mulch
  • Decorative stone
  • Topsoil
  • Gravel
  • Aggregate

Ordering the correct amount saves time, money, and additional delivery charges.


8. Forgetting About Seasonal Maintenance

Landscaping isn't just a spring project.

Throughout Wisconsin's changing seasons, your yard benefits from:

  • Spring mulch refreshes
  • Summer weed control
  • Fall cleanup
  • Winter ice management

Planning for year-round maintenance helps your landscaping stay healthy and attractive in every season.


9. Choosing Looks Over Function

Beautiful landscaping should also be practical.

For example:

  • Decorative stone can improve drainage.
  • Gravel provides stable walking surfaces.
  • Mulch conserves moisture.
  • Topsoil supports healthy plant growth.

The best landscapes combine beauty with long-term performance.


10. Trying to Do Everything at Once

It's tempting to completely transform your yard in a single weekend, but large landscaping projects are often easier—and more successful—when completed in stages.

Avoid It By:

Break your project into manageable phases:

  1. Correct grading and drainage.
  2. Add topsoil if needed.
  3. Install edging.
  4. Lay mulch or decorative stone.
  5. Plant shrubs and flowers.
  6. Finish with decorative accents.

You'll enjoy better results while spreading out both the work and the cost.


Bonus Tip: Buy Materials from a Local Landscape Supply Company

Big-box stores often offer limited product selections and small quantities that aren't ideal for larger projects.

A local landscape supply company can provide:

  • Bulk mulch
  • Decorative stone
  • Topsoil
  • Gravel
  • Sand
  • Aggregate
  • Expert recommendations
  • Convenient delivery

Working with local experts helps ensure you choose the right materials for Wisconsin's climate and your specific project.
