The field instrument for plant professionals

Every verdict,
computed. Not guessed.

Meristem turns your phone into a standards-grade instrument for the green industry. Identify plants, diagnose health, evaluate pruning, assess tree risk, and grade nursery stock, with results computed against ISA TRAQ, ANSI A300, and FDACS. The core works offline.

ISA TRAQ/ANSI A300/FDACS Grades & Standards/Works offline/Built by a licensed Florida operator
Built for the green industry

For anyone who has to put a number on a plant.

Arborists & risk assessors

Deliver a defensible ISA TRAQ rating and hand the client a report, not a hunch.

Lawn & ornamental pros

Identify a weed or diagnose a decline in seconds, then log it to the property.

Nursery growers

Grade stock against FDACS before it ships, with leaf count and root-ball criteria applied.

Grounds & landscape managers

Track plant health and pruning quality across every property from one console.

How it works

From photo to verdict in three steps

1

Capture

Snap a photo, or take a few field measurements. Any phone, online or off.

2

Compute

The engine applies the published standard and returns a verdict with the reasoning shown.

3

Report

Save it to the property and generate a branded PDF to hand a client or keep for the record.

One instrument, five modes

Everything a plant pro measures in the field

01Identified

Identify

Name a plant from a photo with a cloud vision model, or the on-device Florida species model that needs no signal and no key.

02Root rot

Diagnose

Work up pests, diseases, and abiotic disorders against a curated Florida knowledge base built for the field.

03Proper cut

Prune

Grade a pruning cut against ANSI A300 and ISA practice, including over-pruning limits and palm frond rules.

04Moderate

Risk

Run an ISA TRAQ tree-risk assessment with the likelihood and consequence matrix applied for you.

05Florida Fancy

Grade

Check nursery stock against the FDACS Florida Grades and Standards: palm leaf count, root ball, and tree criteria.

The number holds up

Every mode shows its work. When a client or an inspector asks how you got there, you have the standard and the inputs on the record.

Why professionals trust the number

A field tool, engineered like an instrument

Computed, not guessed

Verdicts come from deterministic engines built on ISA TRAQ, ANSI A300, and FDACS. The same inputs give the same defensible result every time.

Built for the field

The core runs on your device. On-device identification and the assessment engines need no bars. Sync when you are back in range.

Questions, answered

Before you sign up

How does Meristem decide a verdict?

Every grade and rating is computed from a published standard, not guessed by a chatbot. Tree risk follows the ISA TRAQ matrices, pruning follows ANSI A300, and nursery grades follow the FDACS Florida Grades and Standards. You see the inputs and the rule that produced the result.

Does it work without a cell signal?

Yes. The pruning, tree-risk, and grading engines run entirely on your device, and an on-device model identifies Florida species with no connection. Inspect a back lot with no bars and sync later.

Do I need my own AI key?

No key is needed for the offline engines or on-device identification. For cloud vision (photo identification and diagnosis) you bring your own AI key, so the cost and the data stay in your control. Meristem never meters or resells AI.

Is my data private?

Your scans and photos are stored privately and are never sold or shared. You can export everything and delete your account at any time.

Who is Meristem for?

Arborists and tree-risk assessors, lawn and ornamental technicians, nursery growers, and landscape and grounds managers. Anyone who has to put a defensible number on a plant in the field.

Is there a free trial, and can I cancel?

Every account starts with a 14-day free trial with full access to every mode. A card is required to start, you are not charged during the trial, and you can cancel anytime before it ends. After the trial it is $19 per month or $190 per year, cancellable whenever you like.

Is Meristem a substitute for a licensed inspection?

No. Meristem is decision support that speeds up and documents your professional judgment. It does not replace a licensed inspection or your own field verification.
