HUMBOLDT

Another step towards ideal turf

STRI Bingley top rank
In all trial types HUMBOLDT reaches the top level.

Green trials
Outstanding scores for shoot density, visual merit and resistance to red thread. Can advantageously be added to mixtures with Browntop bent and Slender creeping red fescue on top playing golf greens. For further sustainability in pure fine fescue greens: Chewings + Slender creeping red fescue.

Chewings fescue has one of the very best winter hardiness levels.

Uniformity at top level
Density and fineness at an extreme level
Suitable & sustainable for lawns and even golf greens
Very high winter hardiness
