Low-pollen native grasses or flat ground covers are preferable. If possible avoid mowing or brush cutting as these activities stir up pollens and mould spores. If it cannot be avoided, protect your eyes, nose and mouth with a mask and goggles. It is also wise to avoid freshly mown grass. Reduce weeds by using inorganic mulch such as pebbles and gravel and plant low maintenance ground cover plants.
Many weeds produce a lot of airborne pollen as well as taking valuable nutrients from the soil.
Organic mulches such as straw, hay and composts often harbour moulds which are allergenic for some people. Planting ground cover will reduce the need for organic mulch and less watering will be required. Choose lightly scented plants. Strong scents can act as an irritant for people with Asthma and allergies and cause symptoms similar to those caused by breathing in pollen or mould spores. Avoid compost heaps.
