Total Lawn Renovation in Arizona: From Weeds to Grass

Total Lawn Renovation in Arizona: From Weeds to Grass

A smooth dirt lot turned into a solid weed mat needs complete renovation.

Step 1: Kill Existing Vegetation

• Apply glyphosate (Roundup) to actively growing weeds. Follow label.
• Wait 10–14 days; retreat any survivors.

Step 2: Choose Renovation Level

• Level 1: Overseed with minimal prep.
• Level 2: Overseed with significant prep (dethatch, aerate).
• Level 3 (recommended): Remove all existing vegetation, start fresh.

Step 3: Soil Preparation

• Rototill 6″ deep.
• Amend with compost, rotted manure, peat, organic topsoil.

Step 4: Grass Selection & Establishment

• Select adapted turfgrass for Arizona (see Arizona Master Gardener Manual).
• Seed or sod. Mow at max recommended height; frequent, 1/3 rule.

Step 5: Ongoing Weed Management

• Annual grass weeds: Dense canopy prevents most. If needed, preemergent herbicide applied 7+ days before germination.
• Perennial grassy weeds: Hardest to control; identify by early spring green-up.

Initial work is heavy, but a healthy lawn pays off for years.
