Golf Courses - Greens Turf
1. Greens Turf grown on USGA rootzone
Rootzone Turf was developed to eliminate the problem of incompatibility caused when turf grown on topsoil is laid onto a high specification sandy rootzone. It is grown on a layer of USGA specification sand, and managed as if it were a golf green. The seed mixture used is 50% bent and 50% fescue, giving a predominately bent sward at maturity.
The typical seed mixture used is:
- 25% Heriot browntop bent - Agrostis capillaris
- 25% BarKing browntop bent - Agrostis capillaris
- 25% Barcrown slender creeping red fescue - Festuca rubra litoralis
- 25% Bargreen chewings fescue - Festuca rubra commutata
The first mowings after sowing are by hand mower at a height of 12mm, and then the triple greens mowers take over. The height is gradually reduced to 6-7mm to give a very dense sward. Top-dressing, using the same USGA sand, is spread every two weeks at 2kg per m2, and brushed in. Verticutting takes place every four weeks. The mature turf is virtually free of Poa annua.
Lifting of the turf takes place when it is approximately one year old. This is the perfect time to lift turf of this type. At this age the turf is strong enough to handle. And, because of the regular top-dressing and verticutting, thatch has not been allowed to accumulate.
Rootzone turf is mown at 6-7mm

2. Greens Turf grown on topsoil
Our greens turf on topsoil is gown for use on pop-up greens, green surrounds, approaches and fairways. It is not suitable for use on USGA specification green constructions.
Because imported rootzone is not used in the production of this turf, it is a much cheaper option that the turf grown on USGA rootzone above. However, in all other respects the turf is grown in the same way.
The seed mixture used is 50% bent and 50% fescue, giving a predominately bent sward at maturity. The typical seed mixture used is:
- 25% Heriot browntop bent - Agrostis capillaris
- 25% BarKing browntop bent - Agrostis capillaris
- 25% Barcrown slender creeping red fescue - Festuca rubra litoralis
- 25% Bargreen chewings fescue - Festuca rubra commutata

3. Creeping bent turf on USGA rootzone
Creeping bent turf is grown on a layer of USGA rootzone. The typical seed mixture is:
- 50% A4
- 50% G6
The first mowings are by hand at a height of 7.5mm, and then the triple greens mowers take over. The height is gradually reduced to 3.5mm. The turf is top-dressed every 10 days with 1kg per m2 of the same USGA sand. Verticutting takes place every four weeks.
