Top Dressing Bermuda Grass: Leveling, Crabgrass Control, and Organic Solutions

The Problem: Bumpy Lawn, Scalping, and Crabgrass Invasion

A homeowner applied a thick top dressing to level a Bermuda grass yard that was difficult to mow. While the grass initially grew thick and green, the uneven surface created ankle-twisting hazards. The lawn was scalped during mowing but has begun to recover with irrigation. Now, however, crabgrass has exploded across the yard, and the Bermuda grass remains green but stagnant. The homeowner is intrigued by the "sugar technique" for soil health but worries about attracting ants.

Organic Solutions: Sugar, Beneficials, and Soil Building

Charlotte, an experienced organic gardener, explains that ants are not a problem if sugar is watered in thoroughly. A healthy soil environment attracts beneficial insects, toads, lizards, and even grass snakes that naturally control ants and other pests. She notes that her own garden thrives with these allies.

To jump-start growth while soil microbes multiply, she recommends applying organic fertilizers such as alfalfa meal or lava sand. Howard Garrett, a leading organic authority, highly recommends lava sand for its mineral content. Charlotte has recently begun experimenting with alfalfa meal, brewing it as a tea for container plants and broadcasting it on the lawn.

Assessing Soil Compaction

Compacted or clay-heavy soil prevents root penetration, limiting top growth. Charlotte advises testing the soil by trying to insert a shovel or sharp stick. If penetration is difficult, the soil needs loosening. For tight clay, incorporating cedar bark mulch (which also repels insects) at a 1:1 ratio with existing soil can create a friable root zone. Organic matter applied topically will gradually work downward, improving structure over time.

Sugar Application and Weed Management

Apply plain white sugar at 1 pound per 250 square feet and water deeply. If no growth improvement appears in two weeks, supplement with alfalfa meal and/or lava sand. For crabgrass, Howard Garrett recommends corn gluten meal—a byproduct of corn syrup production—as a natural "weed and feed" that also suppresses fungal diseases. It is available at some nurseries and feed stores.

Encouraging a Self-Regulating Ecosystem

By eliminating synthetic chemicals and nourishing soil life with sugar, compost, and mineral amendments, the lawn becomes a balanced ecosystem where weeds struggle and beneficial organisms thrive.
