• If you notice that the engine has difficulty keeping up its RPMs in a particular area, for example
because the machine is sinking a little deeper into the ground or the top layer is a hard dry
crust, you can push the handlebar down slightly in this area so that the blades are lifted slightly
and the load on the engine is reduced.
9.6.4. After overseeding
When overseeding, the residual soil is laid on top of the seed bed like a top dressing. The quality
of this residual material depends on the extent to which the terrain was prepared. If the old turf
has not been sufficiently cleared and a lot of felt, moss and dried grass has been left behind, part
of this contamination will also be thrown up during the overseeding. This may leave an untidy
appearance.
For your information:
it is important to carry out the preparations thoroughly,
to avoid a lot of work afterwards. (read § 9.3; page 34)
In such cases, you can do the following:
• Allow the residual dirt, that was thrown up as top dressing, to dry. Once the moisture has eva-
porated, the dirt will crumble and fall into the grooves.
• Now you can rake away any remains of moss or dry grass from the lawn with a rake.
• Any accumulations of residual dirt can also be spread out evenly.
Overseeding treatment has a good chance of success. Under normal conditions with sufficient
moisture and warmth, the new grass will emerge after 10 to 14 days.
If it is too dry or too cold, it may take longer for the grass to germinate. If the seed has not
received any moisture after overseeding and the germination process has not yet started, do
not
add any water The seed still has all its germination potential, and will germinate when sufficient
moisture is available. Be patient and wait for a rainy spell.
If the seed has started to germinate after overseeding and no rainy spell is expected, extra ir-
rigation is
necessary
to safeguard the overseeding treatment. If you do not do this, the germ will
dry out and the seed will be lost.
Which elements can influence the outcome:
•
Wind:
strong wind can cause the seed to be blown away or gathered in another place on the
site. There is more risk of this if the seed has not yet germinated and the wind follows a dry
period.
•
Too much water:
If there is a cloudburst with abundant rain after the overseeding, the soil
may not have enough time to absorb the water. The light seeds float and can be washed away
by the water or gather in less elevated areas.
•
Drought:
as described above, drought is the worst enemy of a young shoot. Especially if the
root of the young plant is insufficiently developed to absorb moisture from deeper soil, it
is highly vulnerable to dehydration. Particular vigilance must be exercised at this stage, to
tackle water shortages through irrigation if necessary.
