What you’ll be able to do

Take a photo of your garden as it actually is right now, weeds and all, and get an AI assistant to hand you back a proper plan. Not just “plant some flowers here” but a season by season list, suggestions that suit your soil and light, and a job list for the first weekend you actually have free. It won’t dig the beds for you. But it will save you hours of squinting at plant labels in the garden centre wondering if that fern will survive against your north facing fence.

Before you start

You need three things, and none of them cost money.

First, a clear photo. Stand at one end of the garden, get the whole space in, and take it in daylight. If your garden’s an odd shape or has different zones (patio, lawn, a shady bit under a tree) take a few photos rather than one squashed panorama.

Second, honest information about your plot. Which way does it face? South facing gets sun most of the day, north facing gets very little, and that changes everything about what will grow. If you don’t know, check which direction the back of your house points using your phone’s compass app, or just notice where the sun is at midday. Soil matters too. You don’t need a lab test, a cheap pH testing kit from a garden centre will tell you if you’re acidic, alkaline or neutral, and that alone rules out or rules in a lot of plants.

Third, be honest about what the garden is actually for. A garden for a toddler and a dog is a completely different brief to a garden you want to sit in with a glass of wine, which is different again from one you want to grow vegetables in. AI can’t guess this. You have to tell it.

One more honest question: how much time will you actually spend on this? Not how much you’d like to spend, how much you will. A “low maintenance” answer changes the whole plant list.

Get set up

You don’t need to buy or download anything new for this. Any of the mainstream AI assistants that support image uploads will do the job: ChatGPT, Claude, Gemini, or Copilot all let you upload a photo and ask questions about it directly in the chat window, on the free tier in most cases.

Open whichever one you already have on your phone or laptop. If you’ve never used one before, it’s the same shape every time: a text box at the bottom, an option to attach a photo (usually a small paperclip or image icon), and you type what you want underneath it.

There are dedicated garden design apps out there too, things like Garden Planner or iScape, which let you drag and drop plants onto a 3D model of your space. They can be useful if you want a very visual, precise layout. But for a beginner just wanting a sensible plan, a general AI assistant with a photo does the job without any extra downloads.

Try it yourself

Here are three prompts, each doing a different job. Use them in order, or just take the one you need.

The first is for getting an overall assessment of what you’re working with.

Here's a photo of my garden. It faces [north/south/east/west]. 
The soil tested as [acidic/neutral/alkaline] with a cheap pH kit. 
I spend about [X hours a week/month] on gardening and want it to be 
low maintenance beyond that. The garden is mainly for [sitting out in 
the evenings/my kids to play in/growing some veg/all of the above]. 
Based on what you can see, what's realistic for this space, and what 
should I be thinking about before I plant anything?

The second is for the actual plan, once you’ve got a feel for what’s realistic.

Using the same photo and the details I gave you, put together a 
planting plan organised by season. Include plants that suit [north 
facing/south facing] gardens with [acidic/neutral/alkaline] soil in 
the UK. For each plant, tell me roughly when it flowers, how much 
sun it needs, and how easy it is to look after. Keep the list to 
plants that are commonly available at UK garden centres.

The third is for turning the plan into something you can actually act on this weekend.

Based on the plan above, give me a first-weekend job list. Assume 
I have basic tools (spade, fork, secateurs) and about 4 hours. 
What should I prioritise first, and what can wait until later 
in the year?

You can keep going from here, asking follow up questions about specific corners of the garden, or asking it to suggest a colour scheme, or asking what to do with a particular ugly patch you hate. Treat it like a conversation, not a one shot request.

Check the result

This is the part people skip, and it’s the part that matters most.

AI plant suggestions are often wrong for your specific climate and soil, even when they sound confident. So before you buy a single plant, check every single one against the RHS Plant Finder on the RHS website. Search the plant name, and it’ll tell you its actual light, soil and hardiness needs; if what it says contradicts what the AI told you, trust the RHS. This is the UK authority on “right plant, right place”, and it’s free to use.

Also worth checking: is anything on your list invasive? Japanese knotweed and a handful of other plants are illegal to plant in the wild or allow to spread from your garden in the UK, and an AI won’t reliably flag this for you. A quick search of the plant name plus “invasive UK” will usually surface it fast.

If you’ve got pets, check the RHS site or a vet charity’s plant list for anything toxic to dogs or cats. Foxgloves, lilies and daffodil bulbs are common garden plants that are also poisonous, and this is exactly the kind of detail an AI can miss or get wrong.

Beyond the plant safety checks, look at the plan against your actual garden. Does the layout make sense given where your shed is, or your washing line, or the tree roots you know are under that “sunny bed” it’s suggested? AI works from the photo you gave it, and photos don’t show everything.

If you’ve got a plant already growing that you’re not sure about, Google Lens or the app PlantNet are quick ways to identify it from a photo, separate from your design assistant. Handy for checking whether that thing taking over the back corner is worth keeping.

If it doesn’t work

Sometimes the AI gives you something vague, generic, or clearly wrong for your climate. Nearly always this comes down to one thing: it didn’t have enough real information to work with.

Go back and be more specific. Instead of “north facing”, say “gets about two hours of direct sun in summer, none in winter”. Instead of “low maintenance”, say exactly how many hours a week you’ll realistically spend. The more concrete detail you give, the less the AI has to guess, and it will guess.

If a plan feels wildly wrong, it’s often because the photo didn’t show enough. Try uploading a couple more angles and asking it to revise based on the fuller picture.

On privacy: don’t upload photos that show your house number, your street name clearly visible on a sign, your car number plate, or anything identifying like a name on a parcel or a school uniform. A garden photo is usually low risk, but crop out anything that gives away exactly where you live if that’s a concern for you. Don’t hand over your full address as text either, just the general orientation and postcode area is more than enough for plant advice. None of the mainstream assistants need your name, address or any personal details to do this job well, so there’s no reason to give them.

Keep exploring

If you want to identify a plant already growing in your garden before deciding whether to keep it, see “How to get AI to identify a plant”. If you’re doing a similar project indoors, “How to get AI to design my room” walks through much the same process for interiors. And if you want to see a rough visual of your planting plan before you commit to spending anything, “How to get AI to create an image” covers how to generate that from a description.
