Planting Depth: For planting the root ball maintains its upper section at an even elevation with the surrounding earth.
Backfill: Create a hole filling mixture combining local soil with compost then gently pack it down to evict air spaces.
Water: Before backing into place add water to help the root base establish stable contact with the soil.
Mulch: Put a 2-3 inch layer of mulch around the base to keep the soil moist and handle temperature properly. Static mulch should not be applied directly against the stem.

Watering and Fertilizing

Watering

New Plants: Water deeply once or twice a week during the first year.
Established Plants: Regular watering during dry periods must maintain appropriate soil moisture levels that stay between soaked and dry.

Annual application of compost with organic content helps make your soil healthier.

Pruning and Maintenance

Pruning

Cut spent flowers from your lilacs along with dead branches while also addressing weak stems that are too overcrowded.
Heavy summer-fall pruning should be avoided because it decreases flowering in the following season.

Maintenance Tips

Regular plant inspections must include detection of pests and disease indicator signs.
New mulch needs to be added yearly as it prevents weed growth.

Common Pests and Diseases

Pests

Lilac Borers: When Lilac Borers drill holes into plant stems the affected area becomes wilted. Use insecticidal sprays or traps.
Aphids: Infestations need treatment with insecticidal soap or neem oil applications.

Diseases

Powdery Mildew: For healthy growth maintain airflow through the plant space and use methods other than overhead watering.
Root Rot: Growth should be positioned in areas with well-drained earth to protect against potential problems.

Seasonal Care
