Kentucky Bluegrass Lawn Care
Known for its dense, self-repairing texture and bluish-green color, but it germinates slowly and its care demands attention. It struggles in the summer months in hot regions like Izmir and is better suited to cool, high-altitude plateau climates.
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: Usually not required; winter rains are sufficient.
- Pruning: Growth slows or stops very much; if needed, cut monthly at a high setting (5-6 cm).
- General care: Avoid walking on the lawn when there is frost, as it can damage the leaves.
- Pests & diseases: In the winter months, pink snow mold (Microdochium nivale) can appear in humid, enclosed areas.
- Frost risk: Very frost-hardy; stays green.
- Pruning: Mow once or twice a month at a high setting (5-6 cm).
- General care: Toward the end of the month, you can begin weed control.
- Watering: If necessary (if there is no rain), 15-20 L/m².
- Fertilizing: Nitrogen (N)-dominant lawn fertilizer (e.g. 25-5-10 NPK), applied to soil at 20-25 g/m², to start spring growth. Do not overapply.
- Pruning: Lower the cutting height to 4-5 cm and begin mowing once a week.
- Plant protection: A pre-emergent herbicide can be applied for summer weeds such as crabgrass (Digitaria).
- General care: Active growth begins.
- Pests & diseases: Monitor for leaf spot and rust diseases (Pucciniales).
- Watering: 20-25 L/m² per week.
- Fertilizing: Second feeding with balanced NPK fertilizer (20-25 g/m²).
- Pruning: Mow once a week at a height of 4-5 cm.
- General care: If the thatch layer is thick, dethatching (raking) and core aeration can be done.
- Watering: 25-30 L/m² per week.
- Pruning: Mow regularly at 4-5 cm.
- Plant protection: If needed, apply an insecticide against soil-dwelling grubs (Scarabaeidae larvae).
- General care: This is the strongest growth period.
- Watering: 30-40 L/m² per week; watering is critical when the hot weather begins.
- Pruning: Raise the cutting height to 6-7 cm to reduce stress.
- Plant protection: In hot and humid weather, apply a protective fungicide against fungal diseases (brown patch).
- General care: Heat stress begins. If possible, water early in the morning.
- Pests & diseases: Brown or ring-shaped dying patches can be a sign of Summer Patch disease.
- Watering: 30-40 L/m² per week or more; water deeply.
- Fertilizing: Not required, fertilizing may encourage disease.
- Pruning: Mow on a high setting (6-7 cm) and only when needed.
- Plant protection: Continue spraying for fungal diseases.
- General care: This is the period of most intense stress. The lawn may yellow and go dormant, which is normal.
- Pests & diseases: Damage from grubs becomes most noticeable this month.
- Watering: 30-40 L/m² per week; continue watering.
- Pruning: Continue mowing on a high setting.
- Watering: Continue regular watering (25-30 L/m² per week) and reduce frequency as the weather cools. Carry out this month's care.
- Fertilizing: If overseeding, apply a starter fertilizer; if not, apply a nitrogen (N)-heavy fertilizer (20 g/m²).
- Pruning: Begin mowing regularly at a height of 4-5 cm.
- Plant protection: If needed, apply an insecticide against soil-dwelling grubs (Scarabaeidae).
- General care: The most important period for repairing the areas damaged in summer. The ideal time for raking (dethatching), core aeration and overseeding.
- Pests & diseases: Dry, dead areas may be caused by summer stress or damage from soil-dwelling grubs.
- Watering: Usually not required; autumn rains are starting.
- Fertilizing: To prepare for winter, apply a "winterizer" fertilizer high in potassium (K) (e.g. 13-25-12 NPK), 20-25 g/m².
- Pruning: As growth continues, keep mowing at 4-5 cm.
- General care: The best period for strong root development. Regularly clear tree leaves that fall on it.
- Pruning: Growth slows; make the final cut slightly higher, around 5-6 cm.
- General care: Clear accumulated leaves from the lawn, otherwise the lawn will be deprived of air and rot.
- General care: It enters full dormancy.
