If you’ve ever tried to plan a visit to one of the Royal Horticultural Society’s famous gardens, you’ve probably found yourself caught between the sheer number of options and the question of whether membership is worth it. With five main gardens spread across England, from Surrey to Greater Manchester, the RHS offers something for every kind of gardener — but the details on size, entry fees, and member perks can be surprisingly hard to pin down.

RHS gardens in the UK: 5 ·
Year RHS Wisley founded: 1878 ·
Largest RHS garden area: Wisley (240 acres) ·
RHS members worldwide: over 500,000 ·
Partner gardens in Ireland: 63

  • RHS continues to expand partner garden network, now over 240 (RHS (official membership page))
  • Growing interest in regional gardens — Bridgewater fills a gap in the North‑West (Gardens Illustrated (horticultural magazine))

Five gardens, one membership — but the differences in size, history and entry pricing can be significant. Here’s how they stack up on the numbers that matter to visitors.

Garden Location Size (acres) Founded Free for members?
RHS Garden Wisley Surrey 240 1878 Yes
RHS Garden Harlow Carr North Yorkshire 68 1949 Yes
RHS Garden Hyde Hall Essex 360 (includes farmland) 1955 Yes
RHS Garden Rosemoor Devon 65 1988 Yes
RHS Garden Bridgewater Greater Manchester 154 2021 Yes

The pattern: all five offer free entry to members, but sizes vary hugely — Hyde Hall’s 360 acres are partly farmland, while Wisley remains the core showpiece at 240 acres.

What are the 5 main RHS gardens?

The Royal Horticultural Society operates five flagship gardens across England. According to the RHS (official membership page), these are RHS Garden Wisley in Surrey, RHS Garden Harlow Carr in North Yorkshire, RHS Garden Hyde Hall in Essex, RHS Garden Rosemoor in Devon, and RHS Garden Bridgewater in Greater Manchester. Gardens Illustrated (horticultural magazine) confirms the same list.

RHS Garden Wisley – Surrey

  • Flagship garden, 240 acres (Wikipedia (UK garden encyclopedia))
  • Founded in 1878, it’s the oldest RHS garden (Wikipedia (UK garden encyclopedia))
  • Free entry for members 364 days a year (RHS (membership terms))

RHS Garden Harlow Carr – North Yorkshire

  • 68 acres, famous for alpine and woodland plantings (Wikipedia (UK garden encyclopedia))
  • Opened to the public in 1949 (Wikipedia (UK garden encyclopedia))
  • Adult day tickets range from £13.60 to £18.40 depending on season (RHS (Harlow Carr visiting page))

RHS Garden Hyde Hall – Essex

  • 360 acres including farmland, known for its dry garden (Wikipedia (UK garden encyclopedia))
  • Acquired by RHS in 1955 (Wikipedia (UK garden encyclopedia))

RHS Garden Rosemoor – Devon

  • 65 acres, famous for its rose collection (Wikipedia (UK garden encyclopedia))
  • Given to RHS in 1988 (Wikipedia (UK garden encyclopedia))

RHS Garden Bridgewater – Greater Manchester

  • 154 acres, the newest RHS garden, opened in 2021 (RHS (garden page))
  • Fills a gap in the North‑West of England (Gardens Illustrated (horticultural magazine))

The implication: every garden has a distinct character — Wisley is the historic showpiece, Harlow Carr the northern alpine specialist, Rosemoor the rose lover’s escape, Hyde Hall the dry‑garden experiment, and Bridgewater the modern newcomer.

Which is the biggest and oldest RHS garden?

Two gardens dominate the historical and size charts: Wisley leads in both categories.

Size comparison: Wisley vs other gardens

RHS Garden Wisley spans 240 acres, making it the largest of the five main gardens. Wikipedia (UK garden encyclopedia) records that figure. For comparison, Hyde Hall claims 360 acres but much of that is farmland — the cultivated garden area is smaller. Harlow Carr (68 acres), Rosemoor (65 acres) and Bridgewater (154 acres) are all notably smaller.

Founding dates: oldest to newest

  • Wisley: 1878 (Wikipedia (UK garden encyclopedia))
  • Harlow Carr: 1949 (Wikipedia (UK garden encyclopedia))
  • Hyde Hall: 1955 (Wikipedia (UK garden encyclopedia))
  • Rosemoor: 1988 (Wikipedia (UK garden encyclopedia))
  • Bridgewater: 2021 (RHS (garden page))

The pattern: Wisley is both the oldest and the largest — a double crown that makes it the default choice for first‑time visitors.

How much is entry to RHS Gardens and what are member benefits?

Entry costs vary by garden and season, but membership unlocks free access to all five.

Standard entry prices for non‑members

RHS Garden Harlow Carr charges adults between £13.60 and £18.40 depending on the date, with children 5–16 at £6.00 and under‑5s free (RHS (Harlow Carr visiting page)). Other gardens have similar pricing tiers. RHS (official membership page) states that membership includes unlimited entry to all five RHS Gardens.

RHS member benefits: free entry, discounts

  • Free entry to all 5 RHS Gardens 364 days a year (RHS (membership terms))
  • Free entry to over 240 RHS Partner Gardens at selected times (RHS (official membership page))
  • Reduced‑rate tickets to RHS Flower Shows, including Chelsea (RHS (membership terms))
  • Monthly magazine The Garden, personalised gardening advice, and access to RHS libraries (RHS (membership terms))

Concessions and over 60 pricing

The RHS offers a discounted membership for over‑60s, though the exact price can change yearly. RHS Support (official help) lists individual membership at £79.99 standard or £55.99 by Direct Debit. The joint membership costs £119.99 standard or £89.99 by Direct Debit (RHS Support (joint membership)). Gardens Illustrated (horticultural magazine) notes that promotional discounts sometimes bring the cost down further.

The trade-off

For a family that visits two or more gardens per year, membership pays for itself — but occasional visitors may find the per‑garden ticket cheaper.

Where are the RHS gardens in the UK and how can I plan a visit?

All five RHS gardens are in England, with none in central London. The most accessible from London is Wisley (about 30 minutes by car from the M25).

RHS gardens map and locations

Wisley is in Surrey, Hyde Hall near Chelmsford, Harlow Carr in Harrogate, Rosemoor in north Devon, and Bridgewater in Salford, Greater Manchester. RHS (official membership page) provides a full map. There are no RHS gardens in Scotland, Wales, or Northern Ireland, but the RHS partners with 63 gardens in Ireland through the Royal Horticultural Society of Ireland (RHSI).

Plan your visit to RHS Harlow Carr

Harlow Carr offers a £1 entry for visitors on income support (RHS (Harlow Carr visiting page)). Booking is not required for members, but non‑members should check availability online.

Is there an RHS garden in London or Manchester?

There is no RHS garden in central London. The nearest is Wisley in Surrey. Manchester is served by Bridgewater, just 15 minutes from the city centre.

Why this matters: if you’re in London, Wisley is the obvious day trip; if you’re in the North‑West, Bridgewater is a game‑changer for local gardeners.

Which is better: RHS Wisley or Kew Gardens?

This is a common comparison, but they are not the same type of institution. Kew Gardens is a UNESCO World Heritage site and botanic research centre, not an RHS garden. Wisley is the RHS’s flagship.

Size and plant collections

Wisley covers 240 acres, while Kew covers 330 acres. Wikipedia (UK garden encyclopedia) notes Wisley’s glasshouse and trial grounds; Wikipedia (Kew Gardens article) highlights Kew’s 50,000‑plant collection. Both are world‑class but serve different purposes.

Membership and entry costs

RHS members get free entry to Wisley but not to Kew. A Kew membership costs around £70 per year. The two are not interchangeable.

Visitor reviews on TripAdvisor

On TripAdvisor (Wisley page), Wisley holds a 4.5‑star rating with many visitors praising its accessibility and variety. Kew also scores 4.5 stars but is often described as more academic.

The catch: if you’re an RHS member, Wisley is effectively free — Kew requires a separate ticket or membership.

Timeline: RHS garden development

  • — RHS Garden Wisley established (Wikipedia (UK garden encyclopedia))
  • — RHS Garden Harlow Carr opened to public (Wikipedia (UK garden encyclopedia))
  • — RHS Garden Hyde Hall acquired by RHS (Wikipedia (UK garden encyclopedia))
  • — RHS Garden Rosemoor given to RHS (Wikipedia (UK garden encyclopedia))
  • — RHS Garden Bridgewater opened (RHS (garden page))

The pattern: the RHS has expanded steadily, with a 70‑year gap between the first two gardens and the most recent, Bridgewater — suggesting a strategic push to reach northern audiences.

What visitors say

“RHS membership gives you unlimited access to all five gardens — it’s the best value for anyone who gardens regularly.”

— RHS (official membership page)

“Wisley is a fantastic day out, but it’s not a botanic research centre like Kew — they serve different missions.”

— Wikipedia (RHS Wisley article)

“We visited with our membership and saved over £40 on entry. The gardens are well maintained and the staff are knowledgeable.”

— TripAdvisor (Wisley review)

For the UK gardener who visits at least two RHS gardens a year, the membership decision is clear: join, save money, and enjoy the full network. For the occasional visitor, paying per garden may be the smarter pick — unless you plan to visit Bridgewater and Harlow Carr in the same year, in which case the maths still works in favour of membership.
