A recent project led to considerable research into low-allergen gardens. Using careful plant selection and consideration to both hard and soft landscaping, it is possible to reduce the amount of airborne pollen. Furthermore, you can enjoy a beautiful garden all year round even with an allergy such as hay fever or asthma.
With diagnosis of hay fever having trebled over the last three decades (Gupta 2007) and currently 50% of children under 18 in the UK suffering from one or more allergies (Allergy UK) it is an issue that needs to be identified right at the start of the project.
Thoughtful design that considers site situation, material selection, plants and people, will ultimately result in a garden that can be enjoyed by all. In addition, incorporating more diversity into the planting design is good for wildlife and will encourage a wider range of insects, birds and mammals into your garden. Some trees, such as Birch, are particularly problematic and it is worth selecting a variety of different species to reduce the amount of airborne pollen.
