How to Get Rid of Dandelions and Weeds in Utah Lawns

The most effective way to get rid of dandelions and broadleaf weeds in Utah lawns is to spot-treat with a selective broadleaf herbicide (containing 2,4-D, dicamba, and MCPP) in early spring (April) or early fall (September) when weeds are actively growing. For natural control, hand-pull dandelions with a weeding tool, getting the entire taproot. Prevent future weeds by maintaining a thick, healthy lawn.

Step 1: Identify Your Weeds

Dandelions: Yellow flowers, deeply lobed leaves, long taproot. Clover: Three-leaf clusters, common in low-nitrogen lawns. Crabgrass: Coarse grass spreading horizontally. See our crabgrass control guide. Thistle: Purple flowers, spiny leaves. Bindweed: White trumpet flowers, twining vines.

Step 2: Chemical Control

Use broadleaf herbicide with 2,4-D, dicamba, and MCPP. Apply at 60-85°F with no rain forecast. Spot-treat individual weeds. Apply pre-emergent in mid-April before soil reaches 55°F.

Step 3: Natural Control

Hand-pull dandelions with a weeding tool after rain. Use corn gluten meal as natural pre-emergent. Horticultural vinegar (20%) kills top growth. Boiling water kills weeds in pavement cracks.

Step 4: Prevent Weeds

Mow at 3-4 inches to shade soil. Water deeply 1-2 times per week. Fertilize on schedule. Aerate annually. See our lawn aeration guide and Spring Lawn Care Tips.
