The new fescues are finer … just as unthirsty

The deep roots of tall fescue have interested water-conscious grass breeders for years. By the time the top foot of soil dries out, most grasses are parched. But with tall fescue, roots go much deeper, so healthier tall fescue can last longer into drought before it turns brown.

The first tall fescues to be introduced were on the coarse side. But now two new tall fescues, 'Bonsai' and 'Twilight', have finer blades and a slower growth habit than all the tall fescues that have gone before. These grasses require much less mowing than more vigorous lawn grasses like rye and bent. Of the pair, 'Twilight' is the deeper green. Both form denser turf than most fescues (which have a tendency to clump).

They require relatively warm soil temperatures to germinate. In California and desert areas, you could sow them into November. In colder climates, September is the last month to sow until May. Both kinds are available as sod or seed, blended or straight.

Like any new grass, these require good soil preparation, fertilization, and regular watering for the first several months until they take hold' start a new lawn now only if you have water to spare. Thereafter, these grasses need periodic watering to maintain them. But their deep roots will take them further into drought without damage.
