SoilIQ™ 2.2.0 expands the app’s soil intelligence platform with LawnIQ™, a new lawn-focused guidance experience designed to help users make better decisions around mowing, watering, seeding, green-up, heat stress and timing windows.
Introduction
For many homeowners, gardeners and lawn-care enthusiasts, outdoor decisions still begin with the same familiar routine: check the weather, look at the calendar and make an educated guess.
A few warm days arrive and it feels like time to seed. A dry afternoon makes it tempting to water. A mild spring week raises questions about mowing, green-up and pre-emergent timing. But what is happening above the surface does not always tell the full story.
SoilIQ™ was built around a simple idea: lawn and garden decisions should not be based on air temperature alone.
Soil temperature plays an important role in seed germination, root activity, lawn recovery, seasonal growth and planting readiness. SoilIQ helps users look below the surface by combining soil temperature, forecast trends, frost risk, saved locations, journal activity and optional probe calibration into one app.
With the launch of SoilIQ™ 2.2.0, the app now introduces LawnIQ™ — a soil-powered lawn guidance system built directly into SoilIQ.
What SoilIQ Does
SoilIQ is an iOS app designed to help homeowners, gardeners, growers, landscapers and lawn-care users make more informed timing decisions using soil temperature and forecast context.
The app shows soil temperature across multiple depths, including the surface, 2 inches, 6 inches and 21 inches. Users can view current soil conditions, 14-day soil forecasts, frost risk, weather context, planting windows and soil timing signals for any location.
The goal is to help users answer practical questions such as:
- Is the soil ready for seed?
- Should I water today or wait?
- Is frost still a concern?
- Are planting conditions improving?
- Is my lawn entering active growth?
- Is this a good time to mow?
- Should I hold off because rain, heat or cold conditions are coming?
SoilIQ is not intended to replace local expertise, product labels or professional judgment. Instead, it gives users another layer of information to support better lawn and garden timing decisions.
Introducing LawnIQ™
LawnIQ is the newest major feature inside SoilIQ.
Where SoilIQ originally focused on soil temperature intelligence and planting readiness, LawnIQ brings that same soil-first approach into lawn care.
LawnIQ helps users understand what their lawn may need next based on grass type, mower type, lawn goal, irrigation setting, soil temperature, forecast trends and recent lawn activity.
The feature is designed to support lawn-care decisions such as:
- mowing timing
- watering guidance
- seeding and overseeding windows
- green-up and active growth conditions
- heat stress awareness
- pre-emergent timing awareness
- lawn status
- whether it may be better to wait
Rather than only showing raw data, LawnIQ turns soil and forecast context into practical guidance. A user can open the app and quickly see whether conditions are favorable, whether watering should be monitored, whether seeding conditions are improving or whether recent activity changes the recommendation.
Lawn Activity and Field Notes
One of the most important parts of LawnIQ is the Lawn Activity log.
Most lawn apps show current weather or basic reminders, but they do not always know what the user actually did. SoilIQ allows users to log actions such as mowing, watering, overseeding, fertilizing, aeration, rain and treatments.
That activity history helps make the app more useful over time.
For example, if a user recently mowed, LawnIQ can reflect that context. If the user logged rain, watering guidance can acknowledge that local rainfall may differ from model data. If the user is tracking a lawn over time, the Journal and Lawn Activity log create a more complete record of what happened, when it happened and what the conditions looked like at the time.
SoilIQ also includes Field Notes for broader observations, photos, planting records and seasonal tracking. This makes the app useful not only as a real-time decision tool, but also as a record of lawn and garden activity over time.
PlantAI™ for Garden and Crop Timing
Alongside LawnIQ, SoilIQ includes PlantAI™, a crop-specific planting guidance system for more than 130 crops.
PlantAI helps users understand what may be ready now, what should wait and what may be approaching a better planting window based on soil temperature, forecast conditions, frost risk and timing signals.
For gardeners and growers, this helps reduce reliance on calendar dates alone. A warm spring afternoon does not always mean the ground is ready, and a frost-free date does not always capture what is happening in a specific location or soil profile.
PlantAI gives users a more grounded starting point for planting decisions.
Saved Locations and Probe Calibration
SoilIQ also supports saved locations, allowing users to monitor different lawns, gardens, properties, fields or client sites from one app.
Each location can maintain its own soil conditions, forecast context, lawn profile, journal history and calibration settings. This is especially useful for users managing more than one growing area or comparing conditions across different locations.
For users with their own soil thermometer or probe, SoilIQ includes optional probe calibration. A user can enter a measured reading for a specific location and soil depth, helping align SoilIQ’s model-based soil temperature estimates with observed local conditions.
This can be useful for properties with microclimates, shaded areas, irrigation differences, compacted soil, slopes or other site-specific factors.
Built for Apple Devices
SoilIQ is built for iPhone, iPad and Apple Watch.
On iPhone, users can check current soil conditions, LawnIQ, PlantAI, saved locations, journal entries, activity logs and forecast trends. On iPad, users get a larger planning view for forecasts, planting windows and journal history. Apple Watch support gives users quick soil and lawn insights from their wrist.
SoilIQ also supports widgets, Siri and Live Activities, helping users keep key soil and timing information close without needing to open the app every time.
Why Soil Temperature Matters
For lawn and garden timing, air temperature is only one part of the picture.
Soil temperature influences how quickly seed may germinate, how roots behave, how turf transitions through seasonal stages and whether conditions are moving toward or away from a favorable window.
For lawns, soil temperature can help inform mowing rhythm, green-up, seeding readiness, pre-emergent timing awareness, heat stress and watering context. For gardens, it can help users understand whether the ground is becoming more favorable for specific crops.
The value is not in treating soil temperature as a magic number. The value is in using it alongside forecast trends, local conditions, site observations and user activity to make better decisions.
That is where SoilIQ is focused.
A More Practical Lawn and Garden Advisor
SoilIQ 2.2.0 is a major step toward making the app more actionable.
The app is no longer just showing soil temperature. With LawnIQ and PlantAI working side by side, SoilIQ is becoming a broader lawn and garden timing platform.
A user can check current soil temperature, review forecast trends, see what crops may be ready, understand lawn timing signals, log what they did, calibrate readings with a physical probe and track multiple locations — all from one place.
For homeowners, the value is simplicity.
For serious lawn-care users and gardeners, the value is context.
For professionals and creators, SoilIQ can serve as a useful tool for explaining why timing decisions should be based on what the soil is doing, not just what the air feels like.
