Large Backyard Project: Why You Need Competitive Bids & a Designer

Question: Need cost estimates for rock border flower beds (multiple dimensions), sprinkler system, new sod, pergola with concrete patio, more beds, and fruit trees. Want phased approach and priority advice.

Answer: Too Many Variables for Accurate Pricing—Get Three Bids

Labor rates, site access, plant sizes, mulch quantities, demolition, material choices (cedar vs. pine pergola), and regional price swings make blind estimates unreliable.

Best process:

1. List every plant (size, quantity), all scope, materials, finishes.
2. Hire a local landscape architect/designer (few hundred to several thousand dollars).
3. Get ≥3 competitive bids from contractors using the same plans.
4. Compare apples-to-apples; you'll quickly see who's fair.

Phasing: address drainage/grading first, then hardscapes, then planting. A designer helps prioritize.
