When to Start Your Landscaping Project
Timing matters more in landscaping than almost any other home improvement project. The wrong season can kill plants, crack hardscape, and cost you money. Here's when to do what.
Spring (March–May): The Planting Season
Best for:
- Annual flowers and perennials
- Garden beds and borders
- Mulch application
- Lawn repair and overseeding (cool-season grasses)
- Fertilization programs
- Irrigation system startup
Why: Soil temperatures are warming, rain is reliable, and plants have the entire growing season to establish root systems before winter.
Tip: Book your landscaper in February for spring work. By March, the best crews are booked 4–6 weeks out.
Late Spring to Early Summer (May–June): Hardscape Season
Best for:
- Patio installation
- Retaining walls
- Outdoor kitchens
- Walkways and driveways
- Sod installation
- Irrigation system installation
Why: Ground is fully thawed and dry enough for excavation, concrete, and grading work. Long daylight hours mean crews can work efficiently.
Tip: Hardscape projects often take 2–6 weeks from start to finish. Starting in May gives you a finished outdoor space by July 4th.
Summer (June–August): Maintenance Focus
Best for:
- Regular mowing and maintenance
- Watering new plantings (critical first summer)
- Minor additions (potted plants, seasonal color)
- Warm-season grass seeding (Bermuda, Zoysia)
Avoid: Major planting projects. Summer heat stresses new plants, and you'll spend more on watering to keep them alive.
Tip: If you must plant in summer, choose heat-tolerant native species and water deeply twice a week rather than lightly every day.
Fall (September–November): The Secret Best Season
Best for:
- Tree and shrub planting (the #1 best time)
- Lawn aeration and overseeding (cool-season grasses)
- Bulb planting (tulips, daffodils, alliums)
- Fall cleanup and leaf removal
- Transplanting existing plants
Why fall is ideal for trees and shrubs: Roots continue growing in cool soil even after leaves drop. Plants establish root systems all fall and winter, then explode with growth in spring. They also need less watering than spring-planted equivalents.
Tip: Fall planting can save 10–15% on plant costs because nurseries discount inventory before winter.
Winter (December–February): Planning Season
Best for:
- Landscape design and planning
- Getting estimates (contractors are slower)
- Dormant pruning of trees and shrubs
- Structural work (drainage, grading)
Why winter planning saves money: Landscapers are less busy and more likely to negotiate on large projects. Design time is free when you're not paying crews to wait.
Tip: Many landscapers offer 10–20% discounts for projects contracted in winter for spring installation.
The Worst Timing Mistakes
- Planting trees in summer: High heat + transplant shock = 50%+ mortality rate
- Installing sod in late fall: Roots don't establish before winter; sod dies or lifts
- Hardscape in winter: Frozen ground, concrete curing issues, and weather delays triple the timeline
- Booking a landscaper in April for May work: You're 6 weeks too late—book in February
Bottom Line
For the best results: plan in winter, plant in spring, hardscape in early summer, and add trees in fall. Phasing your project across seasons also spreads the cost and gives you the best chance of healthy, established plantings.
