Eliminate a lawn problem
Moss on a lawn is a clear sign that the ground is poorly drained and that the grass has been ill treated. Moss killers based on dichlorophen and iron sulphate are available, but no matter how often you use them the moss will return unless you cure the underlying problem. First apply the Moss Killer, then, when the moss is dead, vigorously rake it up. If you do this when the moss is alive you simply spread the spores.
Prevent moss from growing on a lawn by improving drainage. Spike the lawn with an aerator. For a small area, a garden fork will do. Drive it 7.5cm into the soil, allowing about 15cm between each spiking, then, scatter a top dressing of dry horticultural grit or sand at 1kg a square metre. On a larger lawn a roller type aerator will save time.
High pressure help
Moss thrives in damp places, particularly on paving stones and roofs sheletered from the sun. Check gutters at the end of winter and clear moss deposits so the water flow is not blocked. Hire a high pressure hose to remove moss from drives, patios and low roofs. Work down from the top of the roofs to avoid the tiles or slates. Then spray the area with a moss killer that does not contain iron sulphate, which leaves a stain. Brush patios frequently to discourage moss and algal growth.
Wear safety glasses when preparing and scrubbing moss and algae killer into paving, and also when spraying it onto a roof.
Waste not want not
Collect the moss washed off the roof or collected from elsewhere. Leave it to darken and die, then spread it onto the garden as an acidifying mulch. Azaleas, camellias, heathers and heaths in particular will benefit. Nest for a pot plant
Moss makes a useful cushion for pot plants. When it is placed as a lining between the holder and the pot, its moisture retentive qualities create a humid atmosphere and stop the pot drying out. Moss also helps to insulate the plant roots from extremes of heat and cold.
