Connected community gardens
Bring people together around a garden
TerraCity helps neighbours meet around a shared garden: see what is growing, talk about it, share tasks, swap plants and know-how, and earn points by helping each other
A community around every garden
Everyone has a place in the group: simple first steps for newcomers, and tools to get organised for regulars
Tasks to share
Watering, weeding, planting, harvesting: everyone sees where to help and takes a task
Events
Workshops, work days, meetups: register and find them again in the app
Plant swaps
Cuttings, seedlings, surplus: offer and pick up between gardeners and between gardens
Talk about the garden
A discussion space built into the app: talk about what is happening in the garden, post, comment and react
Points to earn
Every task done in the garden earns points, exchangeable for vegetables
The garden becomes a meeting place, not only a place to grow
Who plants what, and when?
In many community gardens, information travels by word of mouth. The result is familiar:
Duplicates and oversights
Without an overview, people replant the same spot, water twice, or forget a zone
A garden that is hard to read
Until something has grown, nobody knows what is already in the ground
Newcomers left guessing
Changed hours, shifts, areas to maintain: the information doesn't reach everyone
TerraCity makes the collective life of the garden readable: a shared plan, the real state of the soil, clear tasks and information that reaches everyone
What TerraCity does
Six tools in one app
Garden map
Find nearby gardens, their opening hours and wheelchair accessibility, then join the community
3D garden plan
A digital twin: plots, beds, trees and sensors. See what is planted, and where
Soil sensors
The state of your soil is reported automatically in the app
Tasks and alerts
Soil needs attention? A task is suggested and the group is notified
Community
Posts, events and plant donations between gardeners and between gardens
Terra, the assistant
Terra advises you on what you can plant, based on your soil measurements. Ask questions by text or by voice
How it works
From soil to action, in four steps
The soil is measured
Sensors follow the state of the ground continuously
Data comes in
Measurements reach the app automatically, with no complicated installation in the garden
Terra advises you
Terra analyses this data and tells you what your soil can host
The group acts
Members share tasks and stay informed
Pilot garden in Metz
The first equipped garden is in Metz. Two zones, vegetables and fruit, are monitored by soil sensors, with their 3D plan and alerts
- Vegetable zone
- Fruit zone
The values shown in the app come from real measurements
Our ambition: to connect community gardens across the Greater Region (Metz, Luxembourg, Saarbrücken, Trier) in a cross-border approach
Who is it for?
Local authorities
A clear tool to follow several gardens, energise communities and make citizen action visible
Collectives and associations
No more word of mouth: plan, tasks, hours and announcements in one place
Residents and newcomers
Discover a garden, scan a QR code, join the group and know where to help
