When summer heat hits it doesn’t just make your AC bill climb – it puts your lawn and garden under serious pressure. Scorched soil, dried-out plants, stubborn weeds, and bare patches aren’t just frustrating, they’re signs that your yard is begging for reinforcements. That’s where mulch and soil enhancements come in.

But if you’ve ever stood in the gardening aisle staring at mulch types like shredded hardwood, straw, or rubber chips – or wrestled with clay soil that refuses to drain – you already know this isn’t always a DIY-friendly job. That’s why many homeowners turn to expert landscapers in Decatur. Read on!

What is mulch and does it help in summer? 

Mulch is simply a layer of material spread over the surface of your soil. It comes in two main types: organic options like wood chips, straw, or grass clippings, and inorganic ones like rubber, gravel, or plastic sheeting. It locks in moisture, so your soil doesn’t dry out as fast under Decatur’s blazing sun. It also helps keep the ground cooler, which gives your plant roots a much-needed break from the heat. Plus, a good mulch layer kills weeds before they can sprout, and during heavy downpours, it prevents erosion by holding the soil in place.

For DIYers, spreading mulch sounds simple, but choosing the right type and knowing when not to use it can make a huge difference.

What is the best mulch to improve soil? 

If your goal is to improve your soil’s long-term health, go with organic options. The top performers usually include:

• Shredded hardwood bark: Affordable and slow to break down, it adds structure to the soil.
• Composted leaves: Rich in nutrients and ideal for garden beds.
• Straw or hay: Great for veggie gardens, but make sure it’s seed-free to avoid weeds.
• Grass clippings: Use sparingly and only if untreated with chemicals—they can compact easily.

As these mulches break down over time, they enrich the soil with nutrients and improve its texture, giving your flower beds, tomato plants, and lawn exactly what they need to thrive.

When should you not mulch? 

While mulch is mostly beneficial, there are times it can do more harm than good:

• Right after planting seeds: Mulch can block light and trap too much moisture, causing seeds to rot.
• Heavy clay soil that needs drying out: Decatur soils are often clay-heavy. If the ground is soggy, adding mulch may worsen drainage issues.
• Near tree trunks or plant crowns: Mulch piled up (“volcano mulching”) can trap moisture and rot the base of trees and shrubs.

Timing is also key. Wait until the soil is thoroughly warm (usually mid-to-late May in Decatur) before applying mulch in spring. Applying it too early can slow growth.

What are other soil enhancements?

Mulch is only part of the puzzle. If your soil lacks nutrients or structure, it may need an extra boost. Here are some effective enhancements:

1. Compost

Compost is the ultimate natural fertilizer. Mixing it into garden beds or topdressing your lawn helps support microbial activity and boosts fertility. It’s especially helpful if your yard is lacking organic matter.

2. Worm castings

These nutrient-rich droppings from earthworms improve plant growth, water retention, and soil structure. Great for raised beds and container gardening.

3. Gypsum

Ideal for heavy Decatur clay, gypsum loosens compacted soil and improves drainage without affecting pH levels.

4. Soil testing kits

Before adding anything, consider testing your soil’s pH and nutrient levels. This small step can prevent over-fertilization and save you money and time.
