Better gardens start with better soil.
Growing vegetables? Planting flowers? Trying to improve your lawn? A simple soil test can help you understand what is already in your soil — and what it may actually need.
For vegetable gardens, flower gardens, lawns and home landscapes.
Give whatever you're growing a better place to start.
Home soil testing isn't just for lawns.
The vegetables in the backyard, flowers along the house and grass under your feet all depend on the soil beneath them. Testing can help identify nutrient levels and soil conditions before you add fertilizer, amendments or another season of guesswork.
One yard. Different growing needs.
Different parts of a yard can have different soil conditions. Testing the area you're actually growing in gives you a better starting point for deciding what it needs.
Grow food with fewer guesses.
Understand soil pH and measured nutrient levels before planting tomatoes, carrots, cucumbers, peppers, herbs and other backyard crops.
Give flowers the soil they need.
Get a clearer picture of the soil beneath annuals, perennials and garden beds before adding fertilizer or soil amendments.
Know before you fertilize.
Soil testing can help identify nutrient levels and soil conditions that may influence lawn growth and fertilizer decisions.
Before adding more, find out what's already there.
A soil test replaces some of the guesswork with actual information about the soil you're trying to grow in.
Understand soil pH
Learn whether your soil is acidic or alkaline — an important factor in how plants access nutrients.
Check nutrient levels
Find out more about the nutrients measured in your soil before automatically adding more fertilizer.
Make informed decisions
Use your results and guidelines as a starting point when planning fertilizer and soil amendments.
Test different areas
A vegetable garden, flower bed and lawn may have different conditions. Separate samples can provide more useful information.
Sometimes the problem isn't the plant. It's the soil.
Starting a new garden
Get a baseline before planting or investing in fertilizer and amendments.
Plants aren't thriving
Nutrients or soil conditions may be one piece of the puzzle when growth isn't meeting expectations.
Before fertilizing
Find out what's already present before adding nutrients your soil may not need.
Planning next season
Use testing as a starting point when planning future garden or lawn care.
A little soil. Three simple steps.
Start by checking the instructions and submission requirements with the Corvian Labs location serving your country.
Collect & mix
Take small amounts of soil from several spots in the lawn or garden you want tested, at a depth of 0–6 inches. Mix them thoroughly in a clean container.
Bag & label
Put approximately 1 lb of the mixed soil into a clearly labelled plastic bag. Give it a simple name such as “vegetable garden,” “flower bed” or “front lawn.”
Complete & send
Complete the appropriate submission form. Confirm payment and delivery instructions with your local lab, then drop off or mail your sample.
Know more about your soil. Then decide what comes next.
Your results and guidelines provide a starting point for caring for the things you're growing.
See what the analysis found in your soil.
Understand measured conditions such as soil pH that may affect plant growth.
Use your results as a better starting point than guessing what to add.
If something still isn't growing well, your soil results provide useful context for the next step.
Choose your lab. We'll help with the rest.
Check current pricing, turnaround times and submission requirements before sending your sample.

New to soil testing? Start here.
Can I test soil from my vegetable garden?
Yes. Home soil testing can be used for vegetable gardens, including backyard and raised-bed growing areas. Tell the lab what you are growing when submitting your sample.
Can I test flower beds and gardens?
Yes. Flower gardens and landscaped growing areas can be tested to better understand measured nutrient levels and soil conditions.
Can I still test my lawn?
Absolutely. The service can be used for home lawns as well as vegetable gardens, flower beds and other growing areas.
Should I combine soil from my lawn and garden?
A lawn, vegetable garden and flower bed can have different soil conditions and care needs. Keeping different areas as separate samples may provide more useful information.
When is a good time to test garden soil?
Testing before planting or before making major fertilizer and amendment decisions can provide useful information for planning. Contact the lab if you have questions about timing for your specific situation.
Can a soil test explain why my plants are not growing?
A soil test can help assess the nutrients and soil conditions included in the analysis. Plant problems can also involve watering, drainage, sunlight, insects, disease and other factors.
What if I don't understand my results?
Contact the Corvian Labs team with your report and questions. Tell us what you are growing and what you want to improve so we can help you understand the next step.
Before you add more, find out what your soil needs.
From tomatoes and carrots to flower beds and the front lawn, start with a soil test and make your next growing decision with better information.
