Horticulture

Propagation, soil and growing media, plant relationships, and whether a plant will thrive where you are.

The Horticulture domain covers questions about how to multiply a plant from what you already have, what a soil or growing medium is doing and how to improve it, which plants help or hinder each other and why, and whether a given plant actually suits a given place.

Specialist Horticulture Tools

Companions

Companion Planting Engine

ONLINE

Examines how plants growing together actually affect each other. It names the mechanism behind every interaction, identifies traditional lineage where it exists, and distinguishes research-backed relationships from practices with limited study.

Cut & Root

Global Plant Propagation Engine

ONLINE

Determines how to propagate any plant from seed, cuttings, grafting, or layering, anywhere in the world. It works from your actual conditions rather than a zone chart, and explains what to adjust when propagation stalls.

Dirt

Plant Growing Media Engine

ONLINE

Examines soils, potting mixes, substrates, and growing media to explain what they are made of, how they behave, where their limits are, what they suit, and how to improve them.

Niche

Plant & Growing Conditions Matcher

ONLINE

Reads the relationship between a plant and a place — what the plant needs, what the location offers, and whether they match for your goal. It returns a fit score, the gaps, what can compensate, and the realistic ceiling.

How the Horticulture Engines Connect

Growing something involves four questions that are usually asked together and answered separately. What the plant needs and whether this place can supply it. What the medium it grows in is doing. How to make more of it. And what its neighbours do to it.

They are not independent. A cutting that will not root may be sitting in the wrong medium. A plant struggling in a bed may be competing with what is next to it rather than failing on light or water. A soil problem and a site problem produce the same symptoms.

Niche, Dirt, Cut & Root, and Companions each take one of those questions directly, so a plant that is not thriving can be diagnosed at the right level rather than treated at the wrong one.
