Ageratum Pink Ball

Soil Preparation 

 Soil type:

• Well draining sandy loam enriched with compost. 

 pH:

• 6.0–7.0 (slightly acidic to neutral). 

 Sunlight:

• Full sun (6 hours daily) to light afternoon shade in hot climates. 

Planting Steps 

Sowing Seeds: 

• Surface sow seeds to 3 mm in trays or directly into soil; press lightly (do not cover). 
• Keep moist with a spray bottle.
• Germination: 5–10 days at 10–25°C. 

Transplanting:   

• Space seedlings 50 cm apart. 
• Harden off indoor seedlings for 7–10 days before transplanting. 

Care Guide 

 Watering:

• Keep soil consistently moist but not waterlogged.
• Reduce frequency once established. 

 Fertilising:

• Apply balanced liquid fertilizer every 4–6 weeks. 

 Mulching:

• Use mulch to retain moisture and suppress weeds. 

 Pruning:

• Pinch tips early for bushier growth.
• Deadhead spent blooms to prolong flowering. 

 Pests/Diseases: 

• Watch for aphids, spider mites, and snails. Treat with neem oil or insecticidal soap. 
• Prevent powdery mildew with good airflow and avoiding overhead watering. 

Seed Harvesting:

• Allow flowers to dry on the plant.
• Collect brown seed heads and store in a cool, dry place. 

 Companion Planting Guide 

Best Companions:

• Marigolds: Deter nematodes and repel beetles; bright contrast with ageratum’s blue. 
• Tomatoes: Ageratum attracts pollinators, boosting fruit set. 
• Zinnias/Sunflowers: Create height contrast and share similar sun/water needs. 
• Basil: Repels flies/mosquitoes; thrives in same conditions. 

Avoid Planting With:

Fennel:

• Allelopathic; inhibits growth. 
• Aggressive spreaders (e.g., mint): Compete for resources. 
• Heavy feeders (e.g., corn): May deplete soil nutrients. 

 Regional Tips 

 Tropical North:

• Grow in winter to avoid wet season rot. 

 Arid Zones:

• Use mulch and water deeply to combat heat. 

 Temperate South:

• Protect seedlings from late frosts with cloches.
