Frequently asked questions.

Most gardening apps either identify plants or track watering schedules. I do something different — I learn your specific climate, watch your weather, and tell you what to do, when, and why. Closest comparison: a knowledgeable friend who texts you the right advice at the right time.

Not a thing. I'm built for the person who killed every houseplant they've ever owned. Every task is explained in plain English. Every guide assumes you've never planted before.

Very, for common garden plants and most weeds. I use a combination of visual recognition and your context — where you live, what you've planted — to make smart guesses. If I'm unsure, I'll tell you, and offer the most likely options.

For most common issues — yes. Yellowing leaves, pest damage, fungal spots, nutrient deficiencies. I combine what I see in the photo with what I know about your conditions to suggest causes and fixes. For the tricky ones, I'll be honest and tell you what to look for next.

Anywhere. Climate-specific data is most accurate in the UK and US right now, but the core features — tasks, chat, guides — work globally. We're expanding hyperlocal data to more regions through 2026.

Your data helps me get smarter for you — what you grow, where, when, what works. That's it. No third-party sharing. No advertising network. You can export everything or delete your account anytime.

Yes. Tasks, plant info, and growing guides all cache locally. Chat, plant identification, and weather updates need a signal — but the daily plan you wake up to works in any garden, even ones with terrible reception.

A small team in Lithuania, led by Justas and Nojus. They've been working on tools for gardeners for years and watched too many people give up because the instructions weren't enough. I'm what should have been there all along.

I have a generous free tier that covers daily briefings, basic plant identification, and your garden timeline. Paid plan details are coming soon. Two minutes to set up, no card needed to start.

Yes — there's no lock-in. You can export your garden data and delete your account anytime from settings. Nothing follows you out the door.

No. Your garden data lives in the cloud, tied to your account — uninstalling the app doesn't delete it. Reinstall, sign back in, and everything is still there.

Both. I do houseplants, vegetable gardens, ornamentals, herbs — indoors and out. The daily morning briefing is most useful for outdoor seasonal crops, but the plant ID, symptom diagnosis, and care reminders work for anything growing in soil.

Yes — log in on iOS and Android, and your garden syncs across devices. Add a plant on your phone in the morning, check on it from a tablet that evening.

Toxicity data for every plant in our library is sourced from the ASPCA's Toxic and Non-Toxic Plant Database — the same authority US vets reference. When you identify a plant or add one to your garden, Growli flags whether it's safe around cats, dogs, or both, and includes the mechanism (calcium oxalates, saponins, etc.) so you understand the actual risk. For species not on the ASPCA list, we say so explicitly rather than guessing.

Both, calibrated differently. For US users we use USDA hardiness zones 1-13 and US frost-date averages. For UK users we use RHS hardiness ratings H1a-H7 and Met Office UK climate norms. Our planting calendar, frost alerts, and species recommendations adapt automatically based on your location. UK retailers (Crocus, Sarah Raven, Marshalls, etc.) and UK-specific cultivar names appear in UK-targeted content.

Our zone and frost data comes from authoritative sources (USDA ARS for US, RHS + Met Office for UK). Planting timing, frost protection alerts, and species hardiness recommendations are calibrated against those. For specific cultivars, retailer names, and current-year regulatory facts (pesticide approvals, etc.), we fact-check via current sources rather than relying on stale training data. If we can't verify a specific number we soften the claim rather than invent it.

PictureThis is excellent for plant identification head-on; Greg has community Q&A and strong species depth. Growli's wedge is different: conversational AI dialog (ask follow-up questions, not just get a species name), proactive daily morning briefings (you don't have to open the app to know what to do), symptom diagnostics with cause analysis, frost and weather alerts, and UK-specific climate data. Many gardeners use Growli alongside another ID app rather than instead of it. Try the free tier and see which combination works for your garden.

We combine your specific conditions (zone, light level, soil, history of what worked) with our species and care library to recommend what's most likely to thrive for YOU. We also cross-check against authoritative sources — RHS, USDA Extension, ASPCA, university horticulture departments — for any safety-critical claim (toxicity, pesticide use, edibility). If a recommendation depends on a regional or seasonal factor we don't know yet, we ask before recommending.
