Tall Fescue Care
Lolium arundinaceum (syn. Festuca arundinacea)
The most heat-tolerant of the cool-season grasses, but it needs plenty of water to survive Manisa's harsh summer months and can catch diseases. It performs best in autumn and spring.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Fertilizing: Not needed. Mowing: growth is very slow, so it is not needed or only once a month.

- Watering: Water deeply once a week (about 25 L/m²).
- Fertilizing: Continue fertilizing. Mowing: continue mowing once a week.
- Plant protection: Use selective herbicides containing 2,4-D for broadleaf weeds.
- General care: This is its healthiest and most lush period.
- Watering: Water deeply 1-2 times a week (25-30 L/m² in total).
