Autumn work decides the state the garden will be in when spring arrives. The height of the last cut, the timing of leaf clearing and a potassium-rich autumn feed all matter, but the most important job is draining the irrigation system: a cracked valve costs far more in spring than the autumn service does.
How to prepare your garden for winter
Autumn work decides the state the garden will be in when spring arrives. This is the season when you can gain, or lose, the most.
The last cut
Do not let the lawn go into winter long, because mold can develop under grass that lies flat. The last cut should be around 4 centimeters, usually in late October or early November.
Leaves are not waste, but they cannot stay on the lawn
Under a thick layer of leaves the lawn overheats and thins out. It is worth clearing leaves in several passes. In the beds, though, leave them: they are a natural winter cover and food for spring.
Autumn feeding
An autumn lawn feed rich in potassium and low in nitrogen strengthens the grass against frost. Late September or early October is the best time to apply it.
Draining the irrigation system
This is the job not to postpone. Before the first serious frost the pipework has to be blown through with compressed air. A cracked sprinkler or valve costs far more in spring than the autumn service does.
Plant protection and pruning
Cover frost-sensitive plants, but leave ornamental grasses standing: the straw-colored stems look good through winter and protect the crown. Their pruning can wait until spring.
