Self-Hosted Garden Planning & Plant Databases: OpenFarm vs Permapeople vs GrowVeg Alternatives

Introduction

Planning a productive garden requires more than good soil and seeds — it demands knowledge about plant spacing, companion planting, crop rotation, and seasonal timing. Self-hosted garden planning tools let you manage plant databases, design garden layouts, and track your growing seasons without relying on commercial services that may disappear or lock away your data behind paywalls.

Whether you are managing a backyard vegetable patch, a community garden, or a small-scale permaculture project, open-source garden planning software gives you the digital tools to plan smarter and grow more. This guide compares the leading self-hosted platforms for garden design and plant knowledge management.

OpenFarm: The Wikipedia of Plants

OpenFarm is a free, open database of plant growing knowledge. Think of it as Wikipedia meets gardening — a collaborative platform where gardeners worldwide contribute planting guides, growing tips, and environmental requirements for thousands of plant varieties.

OpenFarm’s key features:

• Comprehensive plant guides: Each plant entry includes sun requirements, water needs, soil preferences, germination temperature, spacing guidelines, and harvest timelines
• Community contributions: Anyone can add growing tips, pest management advice, and variety-specific notes
• REST API: Integrate plant data into your own garden planning applications
• Search and filter: Find plants by hardiness zone, sunlight needs, water requirements, or edible parts

Permapeople: Visual Garden Design

Permapeople takes a more design-oriented approach, offering a drag-and-drop garden layout builder alongside its plant database. It is built with permaculture principles in mind — emphasizing polycultures, guilds, and ecological design patterns.

Key differentiators:

• Garden bed designer: Create raised bed layouts with drag-and-drop plant placement that enforces spacing rules
• Polyculture guilds: Pre-built companion planting groups with documented synergies
• Seasonal planning: Visual timeline showing when each crop needs to be started, transplanted, and harvested
• Seed inventory: Track your seed collection with viability dates and variety notes

Why Self-Host Your Garden Planning?

Garden planning data is deeply personal and accumulates value over years. Commercial garden planning apps can shut down, change their pricing, or restrict access to your historical data. Self-hosting ensures:

Permanent access to your garden history: Years of planting records, variety performance notes, and harvest data belong to you permanently. When you self-host, no SaaS sunset can take away your accumulated growing knowledge.

Customizable to your climate: Most commercial apps use generic USDA hardiness zone data. Self-hosted platforms let you add micro-climate notes, frost pocket locations, and hyperlocal growing conditions that commercial services cannot capture.

Community knowledge sharing: OpenFarm’s collaborative model means the plant database improves with every contribution. Unlike walled-garden commercial databases, open-source plant knowledge compounds over time as more gardeners contribute.

Integration with home automation: Connect your garden planner to soil moisture sensors, weather stations, and irrigation controllers. For automated garden watering, see our self-hosted garden irrigation guide.

For broader home management, check our home inventory management guide. If you are interested in indoor growing, our hydroponics guide covers automated systems.

Seed starting calendar: Track indoor seed starting dates, germination rates, and transplant readiness. A self-hosted database can calculate optimal seed-starting dates by working backward from your average last frost date — accounting for each variety’s specific “weeks before transplant” recommendation. This replaces the generic paper seed packet instructions with a calendar customized to your actual growing conditions and historical frost data. The system can also alert you when it is time to harden off seedlings, ensuring they transition smoothly from indoor grow lights to outdoor beds without transplant shock, resulting in healthier plants and earlier harvests.

Soil and Climate Data Integration

Modern garden planning goes beyond plant databases — it increasingly integrates with environmental data sources to make intelligent recommendations. Self-hosted platforms allow you to connect these data pipelines directly.

Local weather station integration: Connect your garden planner to a personal weather station (via WeeWX or an MQTT sensor network) to track actual rainfall, soil temperature, and frost events at your specific location. This is far more accurate than relying on regional weather forecasts that may be 50 miles from your garden. OpenFarm’s API can be extended with webhook consumers that adjust planting schedules based on real-time conditions.

Soil test data management: Professional soil tests provide detailed NPK levels, pH, organic matter percentage, and micronutrient profiles. A self-hosted garden database lets you store multi-year soil test results alongside planting records, revealing trends — such as declining phosphorus levels in a bed that has grown heavy-feeding tomatoes for three consecutive seasons.

Historical harvest tracking: Record yield data (pounds harvested, number of fruits, quality ratings) alongside your plant database. Over multiple seasons, this builds a hyperlocal knowledge base of which varieties perform best in your specific microclimate — data that no generic gardening app can provide.

Companion planting validation: Use your own garden records to validate or challenge companion planting claims. Document which plant combinations thrived and which struggled in your conditions, building an evidence-based companion planting reference tailored to your garden.

FAQ

Can OpenFarm work offline for gardens without internet access?

OpenFarm requires a database and search backend, but you can deploy it entirely on a local network using Docker. Once deployed, all plant data is available locally — no cloud dependency. For completely offline garden reference, you can export OpenFarm’s plant data as JSON and build a static site using a static site generator.

How accurate is the companion planting data?

Companion planting recommendations come from community contributions and are reviewed by the OpenFarm editorial team. The data reflects both traditional knowledge (Three Sisters planting, etc.) and modern horticultural research. Permapeople includes scientifically-validated guild designs from permaculture literature. Always cross-reference with your local extension office for region-specific advice.

Can I import plant data from other garden planning apps?

OpenFarm provides a REST API for programmatic data import and export. You can use it to sync plant lists from spreadsheets or migrate from commercial apps. For bulk imports, the API supports JSON payloads with plant attributes. Permapeople offers CSV import for seed inventories and plant lists.

Does self-hosted garden software support multiple users and community gardens?

Yes. OpenFarm is multi-user by design — it is a collaborative platform where multiple gardeners can contribute guides and share knowledge. You can set up separate garden spaces within Permapeople for different plots or community garden members. Both platforms support user accounts and role-based access.

What about integration with smart irrigation controllers?

Garden planning software provides the “what to plant and when” layer, while irrigation controllers handle the “when to water” execution. You can connect them via MQTT or REST APIs. The plant database can inform irrigation schedules (e.g., tomatoes need more water during fruiting), and the garden layout helps map irrigation zones to plant groups.

Can I run this on a Raspberry Pi?

OpenFarm requires more resources than a typical Raspberry Pi can provide — primarily because Elasticsearch needs considerable RAM. A Raspberry Pi 5 (8GB) can run a simplified deployment with SQLite search instead of Elasticsearch for a personal garden database. Permapeople’s lighter stack runs comfortably on a Raspberry Pi 4 with 4GB RAM for small to medium gardens.
