TETRADRY

Excellent drought tolerance!

Excellent visual merit during severe drought

The picture shown at the bottom of this page was taken in our trials on July 6, 2017, after severe drought and high temperatures.

TETRADRY is as green as tall fescue whereas even the best diploid perennial ryegrasses show pronounced loss of colour.

When the target is stay-green during summer

Then TETRADRY is the optimal choice, whether in mixtures with tall fescue (e.g. 20% Tetradry by weight) or diploid perennial ryegrasses (50-60% Tetradry by weight).
