Kentucky Bluegrass and deep rooting (amenity type) Tall Fescue are already proven performers in the American turf industry. In fact, they are by far the most popular drought resistant lawn seed combination sold in the United States to date. With new and improved varieties being bred for ‘Better Shade and Drought Tolerance’, ‘Superior Turf Quality’ and ‘Excellent Disease Resistance’ the full potential of these combined species has finally been realised by the UK lawn seed trade.
With good management Kentucky Bluegrass and deep rooting Tall Fescue will produce a very dense, drought resistant, visually pleasing and durable lawn. The unique feature of Kentucky Bluegrass is it becomes dormant in periods of hot or dry weather but then recovers extremely quickly once rainfall and cooler temperatures return. The root system of Tall Fescue draws its moisture requirements from much deeper in the soil than any other lawn grass and stays green for much longer in extended periods of dry weather. It is also far more heat tolerant than other cool season grasses. Both species are extremely well suited to the UK’s temperate climate along with it’s charateristic occasional summer heatwave and together produce an excellent Drought Resistant Lawn Seed mixture.
The Amenity Perennial Ryegrass acts only as a basic, green cover while the Kentucky Bluegrass and Tall Fescue become established. On free draining soils an Autumn sowing is stronglely recommended as this gives seedlings time to establish a far better root system than anything sown in the spring. Broadcast sow the seeds onto a fine, loose seedbed. Lightly rake over (to mix the seeds and the soil) and then roll the area firm to squeeze the seeds into intimate contact with the soil This blend may also be autumn sown over any hardwearing type lawn that burn up (dry out) during dry, summer weather.
Avoid cutting lower than 25mm in height and feed well in the spring and autumn with a compound fertiliser to produce a darker, more even colour turf with excellent root stock.
