Moss Management

We have this week applied a liquid moss killer to the 10^th & 11^th greens.

The mixture consisted of iron sulphate, seaweed extract and nitrogen.

The iron sulphate blackens and kills the moss, while the seaweed and nitrogen tonic stimulates grass re-growth and improves rooting.

What we have noticed this season is that there is no moss on the wipe up/perimeter cut that the greens mower makes, after the green has been mown.

This is probably because of the extra friction caused by the cutting units as they complete the wipe up cut.

No moss present on wipe up cut 

Usually the cutting units travel in a straight line when mowing, but during the wipe up cut the mowers units are being driven in a circular direction, which causes light scuffing of the turf.

Because moss does not have roots and it is only lightly anchored to the ground by threadlike rhizoids, this scuffing or extra friction seems to be gently removing the moss from the turf sward. 

Next week both these greens will be power raked, over seeded and top-dressed.
