Your landscape plants communicate through their leaves, flowers, and overall growth. When something isn’t right, plants often show warning signs long before serious damage occurs. Learning how to recognize these signals—and more importantly, how to prevent them—can help keep your Indiana landscape healthy and thriving all season long.
At Aspen Outdoor Designs, we believe that a little preventative care goes a long way toward protecting your landscape investment.
Yellowing Leaves: A Sign Something Is Off
Yellow leaves often indicate stress, but the cause isn’t always obvious. Overwatering, poor drainage, nutrient deficiencies, and root issues can all contribute to yellowing foliage.
How to Prevent It
- Water deeply but only when needed.
- Ensure planting beds have proper drainage.
- Refresh mulch annually to help regulate soil moisture.
- Consider soil testing if plants consistently show nutrient deficiencies.
A good rule of thumb is to check the soil before watering. If it’s still moist a few inches below the surface, wait another day or two.
Wilting Plants: Not Always a Watering Problem
Wilting is commonly associated with drought stress, but plants can also wilt when roots are sitting in overly saturated soil.
How to Prevent It
- Water deeply and less frequently instead of shallow daily watering.
- Avoid watering on a strict schedule without checking soil conditions.
- Monitor newly installed plants more closely during hot weather.
- Ensure downspouts and drainage systems aren’t directing excess water toward planting beds.
Deep watering encourages strong root development, making plants more resilient during summer heat.
Brown Leaf Edges: A Sign of Environmental Stress
Brown, crispy leaf margins often appear during periods of heat, drought, or inconsistent watering.
How to Prevent It
- Apply 2-3 inches of mulch around trees, shrubs, and perennials
- Water thoroughly during prolonged dry periods.
- Avoid excessive fertilizer applications.
- Pay extra attention to newly planted landscapes during their first year.
Mulch is one of the most effective tools homeowners can use to conserve moisture and reduce summer stress.
Fewer Flowers and Poor Growth
If plants aren’t blooming or growing as expected, they may not be receiving the right conditions.
How to Prevent It
- Plant sun-loving species in areas that receive adequate sunlight.
- Follow proper pruning schedules for flowering shrubs.
- Remove weeds that compete for nutrients and water.
- Fertilize only when needed and according to plant requirements.
Many flowering shrubs perform best with at least six hours of direct sunlight each day.
Damaged Leaves and Pest Activity
Small holes, chewed foliage, discoloration, or sticky residue can indicate insects or disease.
How to Prevent It
- Inspect plants regularly throughout the growing season.
- Address pest issues early before they spread.
- Keep plants healthy through proper watering and maintenance.
- Remove dead or diseased plant material when noticed.
Healthy plants are naturally more resistant to pest and disease pressures than stressed plants.
Early Leaf Drop
Trees and shrubs sometimes shed leaves early when under stress from drought, improper watering, or transplant shock.
How to Prevent It
- Water newly planted trees and shrubs consistently during their establishment period.
- Maintain proper mulch depth around root zones.
- Avoid damaging roots with lawn equipment.
- Monitor plants during periods of extreme heat or drought.
The first year after installation is often the most critical period for long-term plant success.
The Best Prevention: Regular Walk-Throughs
The easiest way to prevent major landscape issues is surprisingly simple: spend time observing your landscape.
Take a few minutes each week to look for:
- Changes in leaf color
- Wilting or drooping foliage
- Signs of pests
- Poor flowering
- Dry or overly wet soil conditions
Identifying small issues early often prevents costly replacements and more significant problems down the road.

Your landscape is constantly telling you how it’s doing. Yellow leaves, wilting, browning foliage, poor growth, and leaf damage are all signals that a plant may need attention.
