Fruit & Seeds
After flowering, lilacs produce small, brown seed capsules, though they are rarely grown from seed due to slow maturation.
Cultivation & Care
Ideal Growing Conditions
- Sunlight: Full sun (at least 6 hours daily for best blooms) 
- Soil: Well-drained, slightly alkaline to neutral pH (6.5–7.5)
- Hardiness Zones: USDA Zones 3–7 (can tolerate some colder and warmer regions with care)
Planting Tips
1. Best Time to Plant: Early spring or fall
2. Spacing: 5–15 feet apart (depending on variety)
3. Depth: Plant at the same depth as the nursery pot
4. Mulching: Helps retain moisture and regulate soil temperature
Watering & Fertilizing
- Watering: Moderate—keep soil moist but not waterlogged
- Fertilizer: Light feeding in early spring with a balanced fertilizer (avoid high nitrogen, which reduces blooms)
Pruning & Maintenance
- When to Prune: Immediately after flowering (pruning later removes next year’s buds)
- How to Prune: Remove dead wood, thin out old stems, and shape as needed
- Rejuvenation Pruning: For overgrown lilacs, cut back ⅓ of the oldest stems each year
Common Pests & Diseases
- Powdery mildew (white fungal coating on leaves)
- Lilac borer (a wood-boring insect)
- Aphids (sap-sucking pests)
Prevention includes proper air circulation, avoiding overhead watering, and using organic treatments like neem oil.
