Perennial Ryegrass Care
Lolium perenne
Because it is a cool-season grass, it cannot survive Izmir's hot summers and is generally used for overseeding in autumn to keep warm-season lawn areas, such as Bermuda grass, which usually turns yellow in winter, green.
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.
- Watering: If there is no rainfall, water every 2 weeks (10 L/m²).
- Fertilizing: If needed, a very light dose of nitrogen fertilizer may be applied.
- Pruning: Mow regularly at a height of 3-4 cm.
- General care: It continues to grow in winter, albeit slowly.
- Pests & diseases: In the winter months, be careful of fungal diseases.
- Watering: If there is no rainfall, water every 2 weeks.
- Pruning: Mow regularly.
- General care: Clear weeds by hand.
- Watering: If there is no rainfall, water once a week (10-15 L/m²).
- Fertilizing: To encourage growth, apply a nitrogen-dominant lawn fertilizer.
- Pruning: Mow once a week.
- General care: This is one of the fastest growth periods.
- Watering: Water 1-2 times a week (15-20 L/m²).
- Fertilizing: If necessary, continue fertilizing once a month.
- Pruning: Mow once a week.
- Pests & diseases: Leaf spot or rust may be seen.
- Watering: Water 2-3 times a week (20-25 L/m²).

- Pests & diseases: Heat stress begins.
- Watering: Water 3-4 times a week.
- General care: It begins to yellow and die off at high temperatures. Let the bermudagrass grow.
- General care: This grass species usually dies back completely this month. The warm-season grass beneath it takes over the area.
- General care: It is out of season.
- General care: Around now (20 September), it is time to prepare existing warm-season turf (Bermuda) for overseeding by mowing it very short and aerating it with a rake. Wait until October to sow.
- Watering: After sowing the seeds, keep the soil constantly moist until germination (light watering 1-2 times a day).
- Fertilizing: Use a starter fertilizer when sowing.
- General care: When the weather cools (soil temperature 15-20°C), sow the seeds (about 40-50 g/m²) and cover them with a thin layer of topsoil.
- Pests & diseases: Protect the seeds from ants and birds.
- Watering: After the grass emerges, reduce watering frequency and increase the amount (every 2-3 days).
- Pruning: Make the first mowing when the grass is about 5-6 cm; the blades must be sharp.
- Watering: If there is no rainfall, water once a week (10 L/m²).
- Pruning: Begin mowing regularly at a height of 3-4 cm.
- General care: The lawn area that will stay green in winter has become established.
