Get
the Lawnmower out of storage. Clean and grease it and have it serviced
ready for using.
Treat moss if it
is a problem in your lawn.
Feed
with a general or spring fertiliser. Make sure that it is spread evenly.
The lawn may be growing
by now if the weather is mild but only cut if absolutely necessary and
only if the ground is not wet. Make sure that the blades are on the highest
setting.
