Step‑by‑Step Planting Guide

Follow these steps for a successful, water‑wise lawn.

Soil Prep: Test pH, remove debris, and grade for drainage. Incorporate organic matter if needed.

Seeding: Broadcast seed evenly, lightly rake, and firm with a roller for good seed‑to‑soil contact.

Watering: Keep seedbed consistently moist until germination; taper to deeper, less frequent watering.

First Mow: Mow when grass reaches recommended height; ensure blades are sharp to avoid tearing.

Lawn Maintenance Hub

Seasonal guidance for watering, fertilizing, mowing, and renovation.

Spring: Deep, infrequent watering to encourage roots.
Summer: Adjust to conditions; TWCA grass tolerates longer intervals.
Fall: Maintain moisture during establishment and recovery.

Timing: Focus on fall and early spring feedings; follow soil test recommendations.
Notes: Avoid over‑fertilizing; water‑in per label.

Height: Keep within recommended range for species; raise height during heat.
Frequency: Follow the one-third rule: never remove more than one-third of the grass blade at a time, sharp blades protect turf.

Overseeding: Target thin areas in late summer/fall (cool‑season) with appropriate rates.
Aeration: Core aerate compacted soils; combine with overseeding for best results.

FAQ

Quick answers for homeowners using TWCA‑Qualified grasses.

What does TWCA‑Qualified mean?

TWCA‑Qualified grasses are proven to use less water while maintaining turf quality under drought stress. Qualification is based on rigorously designed, peer‑reviewed trials conducted over multiple years and locations.

When is the best time to plant?

For cool‑season regions, late summer to early fall is ideal; spring is a secondary window. In warm‑season areas, late spring into early summer is typical. Check the seasonal calendar above for guidance.

How do I water less without sacrificing quality?

Use deeper, less frequent irrigation after establishment to promote root depth. Pair with proper mowing height and seasonal fertilization for resilience.

Can I mix species (e.g., Kentucky bluegrass and tall fescue)?

Yes. Blends can balance texture, recovery, and drought tolerance. Follow the label’s recommended percentages and seed at the appropriate rate for the mix.

Is TWCA grass available as sod as well as seed?

Many TWCA‑Qualified varieties are available in seed products; some markets also offer sod from participating farms. Use the Where to Buy locator to check availability.

What mowing height should I use?

Follow species guidance in the Maintenance Hub. As a rule of thumb, avoid removing more than one‑third of the blade at a time and raise the height during heat stress.
