Garden design is one of those careers people dream about from an office window: working outdoors, making beautiful spaces, being your own boss. The good news is that it is genuinely achievable, and you do not need to start young or hold a specific degree. The path is part training, part plant knowledge, and part building a body of work that proves what you can do. This guide sets out the routes in, the skills and qualifications that help, how to build a portfolio, and what the job actually pays, drawn from my own route into the profession.
It is an honest picture, including the slow, lean early years. But for the right person, few careers are as rewarding as handing a client the keys to a garden you have brought to life.
Is garden design the right career for you?
Before the how, be clear on the what, because the job is broader than most people imagine. Garden design combines creativity with plant knowledge, technical drawing, budgets and client management, so it suits people who enjoy both the artistic and the practical. It is not just choosing pretty plants.
A designer surveys a site, listens to what a client wants, then produces plans that balance beauty, function and budget. That means drawing layouts, planning levels and surfaces, choosing and combining plants, and often managing the build. You move between studio work and muddy sites, and between creative freedom and a client’s wishes.
The people who thrive have a genuine love of plants, a good eye for space, and the patience to deal with clients, weather and budgets. If you are drawn only to the creative side, the practical demands can come as a shock. Reading our guides to garden design principles and the biggest design mistakes gives a feel for the thinking involved.
Garden design blends the creative and the technical: surveying, drawing plans, choosing plants and managing budgets. It is far more than choosing pretty flowers.
Routes into garden design
There is no single road in, which is both freeing and confusing. Most garden designers train through a diploma or degree in garden design, often after an RHS horticulture qualification, though some are self-taught. Pick the route that fits your time and money.
A garden design diploma is the most popular route, taking around a year part-time, and many run in the evenings or online so you can study while working. A full degree in garden design takes three years and goes deeper, suiting those starting fresh. Short courses and self-study can work for the determined, especially alongside hands-on experience.
Whichever you choose, ground it in plants. An RHS Level 2 or 3 qualification in horticulture builds the plant knowledge that design courses often assume. I took the RHS route first, then a diploma, and the order helped: I could design with plants I actually understood. The Society of Garden Designers lists accredited courses, and the RHS qualifications are the standard horticultural grounding.
A diploma is the most popular route, often studied part-time or in the evenings. Ground it in plant knowledge, ideally an RHS qualification, before or alongside design study.
The skills you really need
Qualifications open the door, but daily success rests on a spread of skills. A garden designer needs plant knowledge, spatial and drawing ability, and the people skills to manage clients, budgets and builds. Weakness in any one shows in the work.
Plant knowledge is the foundation: how plants grow, combine, and perform across the seasons, so a planting plan still looks good in February. Spatial and drawing skills let you plan a space and communicate it clearly, whether by hand or with design software. Increasingly, clients expect clear plans and visuals they can understand.
Then there are the human skills that no course teaches well. You must draw out what a client truly wants, set realistic budgets, and keep a project on track, often managing contractors. Our guides to planning a mixed border and using colour in design show the kind of detailed thinking the planting side demands.
A clear plan is how you communicate a design. Plant knowledge, drawing skill and an eye for space combine in a planting plan a client and a builder can both follow.
Training routes compared
The right route depends on your time, budget and starting point. This table compares the main ways into garden design.
| Route | Time | Cost | Best for |
|---|---|---|---|
| Garden design diploma | Around 1 year part-time | Medium | Career changers working alongside study |
| Degree in garden design | 3 years full-time | High | School leavers, deep grounding |
| RHS horticulture plus self-study | 1 to 2 years, flexible | Low to medium | The plant-focused and self-motivated |
| Short courses and workshops | Weeks to months | Low | Testing the water, topping up skills |
| Apprenticeship or work experience | Ongoing | Earn while you learn | Hands-on learners, site experience |
For most career changers, the diploma plus an RHS qualification is the sweet spot, giving credibility and plant knowledge without three years out of work. A degree suits those starting young who want the deepest grounding. Whatever route you pick, pair study with real, hands-on experience, because design on paper and design that survives contact with a real garden are different things.
Why we recommend grounding in plants first: The most common mistake I see in new designers is gorgeous plans full of plants they do not really know. A scheme can look perfect on paper and fall apart in the ground because the plants fight, flop, or sulk in that soil. When I trained, doing the RHS horticulture qualification before the design diploma meant every plant I drew was one I understood: its size, its needs, its season. That grounding has saved me from countless planting failures and given clients gardens that actually thrive. Learn your plants first, design second. A designer who knows plants deeply will always outperform one who only knows how to draw.
Building a portfolio and finding clients
This is where careers are really made, and it starts before you are fully qualified. A portfolio of real gardens, even unpaid early ones, is what wins clients, so build and photograph it from your very first project. Clients hire from evidence, not promises.
Start with what you can get: your own garden, friends’ and family’s plots, even a community project. Design them properly, see them built, and photograph the results well, because good photographs are what sell you. Three or four strong projects, beautifully shot, beat a dozen scrappy ones. My first portfolio had six gardens, half of them unpaid, and those photographs won me my first paying clients.
Then build a presence. A simple website showing your portfolio, word of mouth from happy clients, and local visibility all bring work. Membership of the Society of Garden Designers adds credibility once you qualify. Studying real gardens helps too, so visit the best, and our guide to designing a garden from scratch mirrors the process you will sell.
Clients hire from photographs, not promises. Design real gardens, even unpaid ones at first, see them built, and photograph them well. The portfolio is your shop window.
What you can earn and going professional
Be realistic about the money, especially at the start. Early fees in garden design are modest, but established designers can earn a solid living, with income rising as reputation and portfolio grow. It is a build-up, not a quick win.
Most designers start part-time or charge low rates while building a name, and the first year or two can be lean. As your portfolio and reputation grow, day rates and project fees rise. London and the South East command higher fees than rural areas. Most income comes from design fees, charged per project or as a percentage of the build, and some designers add project management of the build for extra income.
Going fully professional means treating it as a business: insurance, contracts, clear fee structures, and good record-keeping. Many designers keep a foot in related work, planting, maintenance or consultancy, especially early on. The reward, once established, is creative, varied, outdoor work that is genuinely your own.

The job moves between studio and muddy site. Surveying a plot, listening to the client, and working to a real budget are as much the craft as drawing the plan.
Frequently asked questions
Do you need a qualification to be a garden designer?
No, there is no legally required qualification to call yourself a garden designer in the UK. However, most successful designers train through a garden design diploma or degree, often after an RHS horticulture qualification. Training builds the plant knowledge, drawing skills and credibility that win clients, so while not compulsory, it is strongly worth doing.
How long does it take to become a garden designer?
It typically takes one to three years of training, plus time to build a portfolio. A garden design diploma can take a year part-time, while a degree takes three. Many people retrain while working, then build up clients gradually. Allow a few years from starting study to earning a steady living, as reputation and portfolio grow with each project.
What skills does a garden designer need?
A garden designer needs plant knowledge, spatial and drawing skills, and the people skills to work with clients and budgets. You must understand how plants grow and combine, how to plan space and levels, and how to draw plans clearly. Project management, an eye for detail, and good communication matter just as much as creativity and plant choice.
How much do garden designers earn in the UK?
Earnings vary widely by experience, location and reputation. Early fees are modest, and many designers start part-time or charge low rates while building a portfolio. Established designers can earn a solid living, with day rates and project fees rising with reputation. London and the South East pay more. Most income comes from design fees, with some adding build management.
Can you become a garden designer later in life?
Yes, garden design is one of the most common careers people move into later in life. Many designers retrain in their forties, fifties or beyond, often bringing useful skills from previous careers in art, project management or horticulture. Life experience and a mature eye are real assets in design, and clients often value a designer who has run projects before.
Train in plants first, build a photographed portfolio, and treat it as a business, and a career in garden design is well within reach at any age. The Society of Garden Designers is the professional body to aim for, and our garden design guides will help you master the craft along the way.
