RENOVATE LAWNS
The end of October
was traditionally the time to give the lawn its last cut, but with the
prevalence of milder winters the grass often continues to grow till the end of
November. If your lawn is firm enough to take the mower without causing any
damage then continue to cut the grass. However for these later cuttings raise
the blades to leave the grass a bit higher to help it through the winter. Local
authorities have the same problem, but as they
use large heavy ride on mowers
the weight can do serious damage to the surface so they are more likely to stop
cutting earlier if the surface is too wet.
Raking out moss and thatch |
A couple of weeks
after the grass has recovered from cutting the autumn renovation works can
proceed to put back good health into the grass sward.
When the grass is
dormant we can carry out some serious repair and renovation works. Lawn edges
often break down but can be repaired easily, with a wee bit of hard work. Bare
areas (dog and cat damage) can either be returfed or prepared for a spring
sowing. Moss control can now be tackled and surface aeration can be given to
help drainage. Any weed problem will have to wait till spring as most chemical
weed killers require the weeds to be actively growing to absorb the weed killer
and translocate the chemical to all parts, especially the roots. Always read
the labels when buying lawn weed killers as most broad leaved weeds respond
quite well to chemical eradication, but clover is a lot tougher and needs
chemicals especially formulated to act on these weeds.
Surface renovations in autumn
Where ever there is
poor surface drainage often after a lot of compaction if the lawn is used a
lot, moss can take hold and grow rapidly. This can also weaken the grass
especially in winter as the moss continues to grow and smother the grass.
This
is another good reason to leave the grass higher than normal after the last
cut. This is where the springbok rake is used to rake out as much moss as
possible from the surface as well as thatch built up over the year. The debris
raked up can go on the compost heap. If you have a large lawn you can hire or
bring in lawn specialists with machines to scarify the surface. It is faster
and more efficient than the springbok rake.
Spiking the lawn for surface aeration |
This is usually
followed by spiking or hollow tining the lawn. You can buy a hollow tining hand
tool or on a small scale use the garden fork, but for the folk with large lawns
a machine will carry out this work fast and effortless. Hollow tining removes a
complete core, whereas the garden fork creates a hole without removal of soil.
Cores left on the surface need to be brushed off and again added to the compost
heap. These holes require filling with a lawn autumn top dressing of sand,
sterilised soil and a slow release lawn fertiliser which often has a moss
killer added, (usually sulphate of iron). Brush this in until it all
disappears. These lawn top dressings can be purchased already made up to assist
drainage, feed the lawn and control moss.
Small bare patches
can be scarified and top dressed with compost or sterilised soil, but do not
sow fresh grass seed till early spring.
Attention can now be
turned to edges, if any damage has occurred over the year. Repair edges by
cutting a turf one foot by one foot and one inch or so deep in from the damaged
edge and lift and turn the turf around so the new straight cut is on the edge.
Firm it down and make sure it is level.
Now the lawn is
sorted turn attention to the mower. Winter is the time for cleaning, repairs
and maintenance to make sure the blades are sharp and the rollers the correct
height for the next year.
