About This Software

Vernalo is a garden planner for people who actually grow things. Plan your vegetable garden visually, track what you grow, and know exactly when to plant. Fertilizer recipes, quick-log buttons, and a succession slider keep you ahead of the season. No ads.

Why I Built This

I built Vernalo for myself. Keeping track of watering, rainfall, fertilizer types, and when I last applied them is a real task, and it only gets harder once you're juggling companion planting and what to grow after last season's crop. I wanted a little backup: a way to see at a glance that I already fertilized these tomatoes, or that this plant's growth stage means it needs less water this week, not more.

Life is busy, and it's frustrating when a plant underproduces, withers, or gets covered in aphids or cabbage moths. Vernalo shows me the companion plants that will help my existing garden before I plant them, warns me when I'm about to plant something that will hinder what's already growing, and helps me learn to read each plant's growth stages instead of guessing.

Plan Your Garden

Create raised beds with a click, or place individual plants anywhere on your canvas with spacing guides. For larger areas, paint a whole section with one crop and apply watering or fertilizer per area. For smaller ones, keep notes on each plant that stay with it in its history. Choose a standard fertilizer ratio or build your own recipe. Quick-log buttons mark watering and fertilizing in seconds, for a whole raised bed or a single plant.

Companion Planting and Crop Rotation

See which plants help each other and which ones clash, drawn from established gardening science. Companion planting suggestions are based on what is already growing in your beds, not a generic chart. Crop rotation warnings catch it when you're about to plant the same family in the same spot again.

Know When to Plant

A planting calendar tied to your local frost dates shows when to start seeds, transplant, and harvest. "What to Plant Now" gives today's best options for your location and the week ahead. The succession slider lets you plan months out, so you know what's going in the moment the current crop comes up.

Design the Whole Garden

Sketch paths, fences, and water features with the design paint tool, and drop in notes anywhere. As you harvest and replant, Vernalo keeps the history: what grew there, what came before it, and the year before that. It becomes a garden journal that fills itself in as you work. Every season builds on the last.

Works Everywhere

Available in 90+ languages with localized plant names and regional crop recommendations. Works offline, so your garden planning keeps working out in the yard, in the greenhouse, or anywhere the signal drops.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Claude Code was used to develop this app. This software uses AI and machine learning in the following ways:

- Plant identification: User-uploaded photos are analyzed by AI to identify plant species, mushrooms, and insects.
- Disease detection: A trained machine learning model analyzes plant photos to detect and diagnose diseases. - Thermal imaging analysis: AI assesses plant health from user-uploaded thermal images.
- Garden import: AI vision interprets uploaded garden
photos and documents to auto-populate garden layouts.

All AI features are user-initiated tools that proces user-provided images. No AI was also used to populate the intitial set of image tiles, while I am paying an illustrator to replace them with hand created art.
