How to choose
Most growers do not need to compare every feature. Three questions narrow the field fast:
- 1. Indoor only, or indoor + outdoor? Planta and Blossom are indoor-houseplant-first. Growli covers both at parity, with frost alerts and outdoor planting calendars. Greg covers both but US-only.
- 2. US, UK, or both? Most apps are US-leaning. Only Growli ships native RHS hardiness ratings (H1a–H7) and UK Met Office weather integration. UK gardeners save mental conversion time by starting here.
- 3. Identification, or ongoing care? PictureThis wins on raw species identification (400,000+ species claimed). Greg has the deepest care library. Growli wins on the conversation after identification — diagnosis, daily plan, weather.
Beyond those three, the free tiers vary more than the paid prices do. Growli is free to download with the garden plan, weather-timed care tasks and frost alerts included; Greg has the next most generous free tier; PictureThis and Blossom have short auto-converting trials.
