A Bermuda lawn in Georgia and a Tall Fescue lawn in Ohio need completely different care calendars. LawnBook's Seasonal Planner generates month-by-month recommendations based on each client's specific grass type, USDA hardiness zone, and local climate patterns. This guide explains how to generate, customize, and share seasonal plans.
What Goes Into a Seasonal Plan
The planner combines three inputs to generate a care calendar:
- Grass type — Set on the client's property record (warm-season vs. cool-season, and specific cultivar)
- Region and climate zone — Derived from the property address, cross-referenced with USDA zone data
- Current date and season — The plan adjusts based on where you are in the calendar year
The output is a 12-month calendar with specific actions called out for each month, including the reasoning behind the timing — not just "apply fertilizer in April" but "apply slow-release nitrogen in April as soil temperatures reach 55°F and before spring growth flush."
Supported Grass Types
Generating a Plan
- Open any client's profile page
- Ensure the property record has a grass type and address set
- Tap Seasonal Plan from the client overview
- Review the generated 12-month calendar
- Make any adjustments based on your local knowledge
- Save to the client's record or export as PDF
Plans can also be generated from the AI tab by asking the Lawn Assistant: "Create a seasonal plan for [Client Name]" or by browsing to AI → Seasonal Planner and selecting a client from the list.
Tip: Generate seasonal plans for all your clients at the start of each year. Even if you don't share them with clients, having a written plan per property keeps you from relying on memory for when each lawn needs what treatment.
Fertilizer Schedules
The fertilizer section of each plan specifies:
- Number of applications per year (varies from 2 for low-maintenance types to 6+ for Bermuda)
- Timing of each application relative to seasonal transitions
- Recommended N-P-K ratios for each application
- Whether slow-release or quick-release formulas are appropriate
- Application rate guidance based on property square footage
These recommendations are general guidelines based on turf science best practices. Soil test results should always take precedence when available. If a client has had a recent soil test, you can note the results in their client profile and the AI incorporates them into recommendations.
Aeration and Overseeding Timing
Aeration timing is critical — aerating a warm-season lawn in fall when it's heading into dormancy causes unnecessary stress. The Seasonal Planner flags the correct aeration window for each grass type:
- Warm-season grasses (Bermuda, Zoysia): Core aerate in late spring to early summer, during peak growth
- Cool-season grasses (Fescue, Bluegrass): Core aerate in early fall, 6–8 weeks before first frost
Overseeding windows are similarly specific. Overseeding cool-season lawns requires soil temperatures between 50–65°F for reliable germination. The planner calculates the typical window for your client's location based on historical climate data and flags the target weeks in the calendar.
Tip: Use seasonal plans as a upsell tool. When you present a client with a written year-round care calendar, it makes the value of regular service tangible. Many operators report converting single-service clients to ongoing contracts after sharing a seasonal plan.
Pre-Emergent Application Windows
Pre-emergent herbicide timing is one of the most time-sensitive decisions in lawn care. Applied too early and it breaks down before the weed seeds germinate; applied too late and the weeds are already up. The Seasonal Planner provides the target soil temperature threshold and typical calendar window for pre-emergent applications specific to your region.
For crabgrass prevention (the most common application), the target is soil temperatures consistently reaching 55°F at 2-inch depth for several consecutive days. The planner estimates this window for your client's location and adds a reminder to your schedule timeline.
Exporting and Sharing Plans
Export any seasonal plan as a branded PDF from the client's profile page. The PDF includes:
- Client name and property address
- Grass type and region
- Month-by-month care calendar
- Your business name and contact details
Share the PDF via email, text, or AirDrop directly from the export screen. This is effective for commercial accounts, HOA contracts, and clients who appreciate documentation of the work being done on their property.
Seasonal Plan Reminders
When a seasonal plan is active for a client, LawnBook can generate schedule suggestions as seasonal windows approach. For example, when the pre-emergent window is two weeks out, you'll see a prompt in the Dashboard to schedule that application for affected clients. This keeps critical timing windows from slipping past in the busyness of a full season.
