Help shoppers choose the right plant before checkout.

Give every variety a clear climate-fit verdict: will it grow, will it fruit, and when can it go in the ground. Help customers buy with confidence and catch bad-fit purchases before they become refunds.

NOAA climate records USDA hardiness zones University extension research

Every plant buyer is asking three questions.

SoilStack turns those questions into product-page answers before checkout, so shoppers buy with confidence before confusion becomes support questions, replacement claims, or bad reviews.

See the climate-fit tools

SoilStack checks the shopper's location against the variety's growing needs, then shows a clear climate-fit answer your product page can use.

Climate-fit verdict

For fruit trees and perennials, SoilStack checks whether the shopper's location gets enough winter chill, the part a hardiness map cannot answer.

Winter-chill verdict

SoilStack uses local frost history to show a safer earliest planting date, instead of leaving shoppers with a generic regional guess.

What it is

A climate-fit layer for
your catalog

SoilStack turns each catalog variety and shopper location into guidance your product page can use before checkout: climate fit, fruiting outlook, planting timing, and a better-fit option when needed.

Step 1 · Your inputs

Start with two inputs

Catalog variety Honeycrisp Apple
Shopper location ZIP 50309

Your product page already knows the variety. SoilStack adds the shopper's location.

Step 2 · SoilStack checks

Check the climate fit

Hardiness Can it survive winter?
Winter chill Will it set fruit?
Frost window When is it safe to plant?
Step 3 · Product-page guidance

The shopper gets a clear next step before confusion becomes support questions, replacement claims, or bad reviews.

Winter chill

Hardy does not always
mean fruitful.

A tree can be hardy enough to sell into a region and still be the wrong fruiting fit there. SoilStack checks the shopper's location against the variety's chill needs, so your product page can show when a variety is a strong fit, borderline, or short on winter chill before checkout.

Winter survival is not fruiting suitabilityUSDA zones are based on average annual extreme minimum winter temperature. Winter chill is a separate requirement that affects dormancy, bloom, and fruit set.
A store-ready answer, not another research taskMany nurseries publish a variety's chill requirement. SoilStack adds the local side, how much winter chill the shopper's location usually gets from NOAA climate normals, and turns it into a clear product-page fit signal.

Frost windows

A zone is not a planting date.

Customers often use hardiness zones like planting calendars, but a zone does not tell them when frost risk usually drops enough for outdoor planting. SoilStack turns local freeze history into product-page timing guidance, so your store can show a clearer plant-after date instead of leaving shoppers with broad regional advice.

Local freeze history, not generic zone adviceUSDA zones describe winter cold hardiness. Frost windows help answer when outdoor planting becomes lower risk in a specific location.
Both ends of the seasonSoilStack checks the last spring freeze and first fall freeze, so guidance can cover planting, seasonal shipping, and harvest.

Climate Fit

Turn climate checks into one buying decision.

Climate Fit is designed to combine hardiness, winter chill, and frost timing into one product-page verdict for a variety at the shopper's location. When a variety is a poor fit, SoilStack can point the shopper toward a better-fit option from your catalog before a bad-fit order happens.

One verdict, not three lookupsZone, chill, and frost timing become a single product-page answer instead of separate numbers for the shopper to interpret.
A better-fit path, not a dead endWhen a location is short on chill, frost timing is not right yet, or the fit is otherwise borderline, SoilStack can guide the shopper toward a better-fit option you already carry.

Partner setup Coming soon

Built to work with your catalog

SoilStack is designed to drop the climate layer into the store you already run, mapped to your catalog and styled to match.
Here is how a partnership comes together.

1

Match your catalog

We map the climate layer to the plants you sell, by variety, SKU, or collection, so every product page knows exactly which crop it is talking about.

2

Pick the placement

Show the guidance however fits your store: a compact badge, an inline panel under the product, or a paste-in widget you drop onto any page.

3

Match your brand

Colors, labels, and wording are tuned to your site, so the climate guidance reads like a native part of the page, not a bolted-on tool.

4

Start with a pilot

Begin with one high-risk category like fruit trees or bare-root stock, prove it out on real orders, then roll it across the rest of your catalog.

Complementary products

More decisions the same climate layer can power

Climate Fit is the starting point. The same location-aware layer can extend into adjacent decisions your store and shoppers face, from pest risk to freeze monitoring to support-ready plant knowledge. These are on the roadmap, not live yet.
