DEMENTIA Central to designing a garden for people with dementia is to understand what dementia is and how it affects human health and behaviour. Dementia is a syndrome, a group of related symptoms that is associated with an ongoing decline of the brain and its abilities, including thinking, language, memory, understanding, and judgement. People with dementia may also have problems controlling their emotions or behaving appropriately in social situations. Aspects of their personality may change. Most cases of dementia are caused by damage to the structure of the brain (NHS, 2010). This decline in brain function can have the effect of causing confusion, hallucinations, agitation and difficulties in controlling body movements. The majority of people with dementia are over 65 years of age and may have additional sensory impairments associated with aging such as deteriorating eyesight and hearing. They may also have declining physical mobility and strength as well as painful arthritic conditions etc. For further resources on understanding the needs of those with dementia see the Resources section on pages 5-6. Approximately 71,000 people have dementia in Scotland in 2010. Around 2,300 of these people are under the age of 65. The numbers of people with dementia in Scotland are expected to rise to 127,000 by 2031 (Alzheimer Scotland, 2010) Fundamental to helping people with dementia to garden is being able to provide an appropriate level of support and a focussed, manageable activity which appeals to the person at the time. One-to-one and one-to-two support is often useful to facilitate tasks depending on individual ability. In addition, gardening activities are an enjoyable way for family members and carers to spend time together with those they care for.

Having access to a garden can meet many health needs for people with dementia and their care
givers, for example:
Physical health benefits. Garden activities provide exercise, for large and small muscle groups.
This maintains and improves muscle tone and hand & eye co-ordination.
Opportunities for Vitamin D production in skin in response to sunlight (Cobley 2003) Provides stimulation with colour, smell and sounds of wildlife. Multisensory stimulation (Cobley
Opportunities to relieve tension, frustration and aggression and bring about positive mood change
Provides personal space for reflection and privacy; reminiscence opportunities for self-expression
and reinforcing a sense of self (Cobley 2003)
Provides different social environments: group activity reinforcing intimacy, privacy for solitude
Caring for plants may alleviate feelings of helplessness and of being dependent on others for care
GARDEN DESIGN A garden for people with dementia should be one that is easy to use and understand, free from ambiguity and one that provide opportunities for meaningful activity within it. To compensate for the various perceptual changes experienced by a person with dementia, garden design should strive to provide structure and reduce anxiety and confusion. Consider including the following elements: Access from garden to adjoining building should be obvious and visible e.g. visible,
accessible doors, porch and path leading to garden or building entry.
An enclosed garden may be useful to keep wanderers in and provide shelter. The fencing,
walls should be visually inconspicuous and can be disguised by planting.
A returning path system is useful to lead you on a journey through the garden returning
back to the house or building (Kennard 2006), e.g. a figure of 8 or a more freeform loop.
Sturdy, comfortable seating, ideally with line of site from one seating area to another to
provide opportunities to admire, rest, contemplate, socialise and continue the journey around the garden.
GARDEN DESIGN continued Easy visible access to toilet from garden. Consider the mood and feeling of the garden. Create areas for communal activity and
areas for being alone or in smaller groups. Include places to sit, shelter from the sun and the wind. Bushes and trees provide structure and can direct movement around the garden.
Think about garden access in all weathers. Provide protection from the extremes of
weather throughout the four seasons of the year. Conservatories, greenhouses, pergolas, portable parasols, summerhouses or an indoor/outdoor activity room with access to the garden, all offer shelter and extend gardening access throughout the seasons, especially in the changeable Scottish climate. Protection from the sun in summer is important as certain medications, e.g. largactil (Thorazine) or mellaril (thioridazine), can make the skin more prone to sunburn.
Think broadly about who will use the garden, e.g. those with dementia, friends and family,
residential care staff .Plan for a range of ages and abilities. Include activities and play facilities that allow generations to interact, e.g. a slide, a games table, garden, BBQ. Think about visibility and observation so caregivers can still relax if they use the time for separate pursuits.
Consider locality and cultural trends as they may suggest appropriate objects to include in
garden, e.g. mining area; seaside setting; residential home for those in media professions. These may all have bearing on items to include in the garden which reinforce the sense of setting or of self-identity. For further resources on understanding the needs of those with dementia see the Resources section on pages 6-7.
Incorporate bird feeders or a bird table or bath, with opportunities to sit comfortably and
As well as dementia, consider specific disabilities that deny use of one or more senses –
gardens can be designed to have specific design features to compensate for that disability e.g. impaired vision – planting that can easily be reached, touched, smelt and with accessible signage, e.g. Braille; large text and high visibility tools that are easy to see against soil and vegetation.
Consider physical access for gardening activity, i.e. provide seating or wheelchair access –
‘table top’ beds, potting benches with space to allow chair users legs to slot in underneath and allow people to have hands in contact with plants & soil.
Use the Dementia Design Checklist to see if your garden design is dementia friendly. From

First steps to designing a garden
Consultation is another key aspect of designing a garden for people with dementia, as it is for any
Directly consulting all those who will be involved in using the garden can reveal many aspects and
issues which would otherwise be unknown and can lead to a garden that will be well used and become
a vibrant and useful social space. Consider who you consult, include:
Service users - people with dementia are individuals, with particular needs, abilities, likes and
Consider how you consult. In order to enable views and preferences to be expressed consultation can be carried out in a series of discussions and events as part of daily activities. For those with dementia which affects their ability to communicate, using a series of pictures to communicate garden features, plants, likes and dislikes and other preferences may be a useful tool. It is useful to find out What are everyone’s expectations of a garden? What specific features, planting etc would they like? What resources/funding is available for now and in the future?
Providing a safe garden
Safety issues are central to good garden design for people with dementia. The design should include: Pathways that are smooth, and low in glare.
Appropriate path width and patio area is very important if you are catering for wheel
chair users. As people with dementia tend to lose physical skills and ability over time, it may be a good idea to cater for mobility aids at the outset.
Too much light reflection or too many dark areas are not helpful to older people who can
have problems with their sight. A number of degenerative eye conditions are common in old age that can cause problems with perception, e.g. dark manhole covers can be perceived as holes in the ground
Use upward bevel edges on concrete walkways. This can keep wheelchairs from rolling
Handrails can be used along the pathways to help those who have difficulty in walking
Successful gardening relies on making the most of the local climatic and soil conditions. Many
general gardening resources can advise on this. In relation to planting gardens for people with
dementia, here are a few guidelines that may be borne in mind:
Avoid creating large dark shadowy areas with dense trees and shrubs. As well as create
difficult plant growing conditions, people with dementia can perceive these areas as being
forbidding or off putting. Trees such as birch or cherry can provide light cover.
To find more information on which plants grow in particular conditions try the RHS Plant
Maximize perennial planting. Annuals take up more time but seed sowing and propagation can
be incorporated into meaningful garden activity.
Place herbs, lavender and other scented plants so that when brushed they will release their
Use non-poisonous and nontoxic plants. Some plants can harm people if eaten; others can
cause skin rashes and irritation. Consult the Royal Horticultural Society listing of potentially
hazardous garden plants at
Plant spiky, thorny plants out of arms reach or at the back of a border, where their architectural
attributes can be admired, without presenting a hazard.
Always consult the person to see if the activity is something they would like to do, or do part of, or just
watch (Cobley 2003)
Remember that taking a family member or a friend with whom to share the garden experience with, is
often an enjoyable social activity.
Prompts for interaction and reminiscence can be found in the garden. For example, looking at flowers,
fruit, vegetable and herbs, admiring the beauty of the shape, colour, flower, texture and smell can all
stimulate the senses and provide enjoyment.
Be culturally aware, e.g. for older people, traditional garden plants such as roses, lillies etc. can evoke
memories. Also daisy chains, dandelion clocks, conkers, unusual wartime recipes and old remedies
from nature can all be brought up in conversation (Cobley 2003)
Using things grown in the garden suggests further activities such as arranging flowers (incl. drying &
pressing them), leaf/potato print cards, make lavender bags and sprays, pot pourri, muslin bath herbs
as well as preparing and eating produce from the garden (Cobley 2003).
Physical gardening can be enjoyed as well as garden watching, try bringing chairs into the garden
Plan the garden using plant catalogues, garden books, magazines, TV programmes and gardening
web pages such as the BBC.
