Grubs, Fungus & Spring Dieback: What to Expect in Your Lawn This Season

As we enter the middle of the warm season, lawns in South Carolina begin showing signs of stress from insects, disease, and environmental changes. Homeowners often notice brown areas, thinning patches, or irregular dead spots, but aren’t sure what’s causing the damage.

At Lawn Doctor, the most common mid-season lawn issues we diagnose include grub activity, fungus outbreaks, and spring dieback—especially in centipede lawns.

Here’s what you need to know.

  1. Grub Activity: The Hidden Lawn Killers

Grubs are beetle larvae that feed on the roots of your grass. This root damage causes the turf to peel up like carpet, leaving large dead patches.

  • Signs of grub damage:
  • Soft, spongy turf
  • Irregular brown patches
  • Animals digging (raccoons, armadillos, birds)
  • Sections of grass lifting easily from the soil

Preventing grubs early is far easier than repairing grub damage later. Lawn Doctor’s grub prevention treatments shield your lawn before the larvae become active.

  1. Fungus Problems: Brown Patch & Zoysia Patch

Warm, humid weather creates perfect conditions for lawn fungus. The most common fungal diseases in our area include:

  • Brown Patch (Tall Fescue & Other Cool-Season Grasses)
  • Circular brown rings
  • Soft or rotting grass blades
  • Zoysia Patch
  • Orange or copper-colored ring edges
  • Slow-spreading patches
  • Take-All Root Rot (TARR)
  • Widespread yellowing
  • Grass that looks starved or weak

Once lawn fungus sets in, it spreads quickly. Professional fungicide treatments from Lawn Doctor stop the spread and protect new growth.

  1. Spring Dieback: The Centipede Lawn Problem
  • Centipede grass is unique—it is sensitive to:
  • Temperature swings
  • Winter injury
  • Nutrient imbalances
  • Thatch buildup

As a result, many centipede lawns experience “spring dieback” each year, where grass fails to green up in certain areas.

How Lawn Doctor repairs spring dieback

Soil testing (to diagnose pH or nutrient issues)

Custom fertilization adjustments

Targeted seeding or plugging

Fungicide if root rot is present

Thatch reduction and aeration

Catching spring dieback early leads to faster recovery.

✔ Monitor for early fungus symptoms
