Parameter

Description

Scientific Name

Zinnia x hybrida

Hybrid

Profusion Double Mix

Plug Culture

Use a well-drained media with low nutrients. Water the plug tray before sowing until drip point. Sow seeds and cover with light vermiculite. Maintain 21°C day and 18°C night temperature. Plants are ready for transplanting after three weeks.

Pot Preparation

Peat-lite mixes with peat, perlite and vermiculite at soil pH 5.8–6.2.

Climate

Sensitive to disease in cool temperatures (below 16°C). Warm temperatures above 24°C may stretch plants. Profusion series is highly disease tolerant but recommended to follow proper temperature guidelines.

Season

Winter (Jan–April)

Fertilizers & Manures

Weekly application of 200–250 ppm Nitrogen using calcium nitrate-based fertilizer. Apply 0.25 ppm boron with each fertilizer application to prevent boron deficiency (tip abortion, crinkled leaves, leaf edge burn).

Irrigation

Water at the base to keep foliage dry and prevent stem rot and leaf spot. Drought tolerant once established but performs better with regular irrigation during dry spells.

Any Special Crop Practices

Pinching: Pinch at 3 inches height for bushier growth.
Photoperiod Control: Short days (<11 hours) promote earlier flowering and compact growth.
Deadheading: Not required but improves plant appearance.

Diseases

Name of the Disease	Symptoms & Management
Powdery Mildew	White powdery coating on leaves and stems. Control: Maintain spacing (12–15 inches), water at base, use potassium bicarbonate, neem oil or sulfur fungicides.
Alternaria & Cercospora Leaf Spot	Reddish-brown spots with gray centers. Remove infected leaves and apply copper-based or chlorothalonil fungicides.
Bacterial Leaf Spot	Angular dark spots with yellow halos. Prevent by sanitation and avoiding overhead irrigation.
Aster Yellows	Flowers turn green or deformed. No cure; remove and discard infected plants.

Pests

Name of the Pest	Symptoms & Management
Aphids	Yellowing leaves and stunted growth. Control: Water spray, insecticidal soap, ladybugs. Chemical control: Acepahte 75% SP (0.5 g/L), Dimethioate 1ml/L, Imidacloprid 30.5% SC @ 0.25 ml/L, Diafenthiuron 50% WP @ 1 gm/L.
Spider Mite	Brown spots and fine webbing in hot dry weather. Control: Insecticidal soap and proper irrigation.
Thrips	Scarring on petals and deformed buds. Control: Insecticidal sprays.
Japanese Beetles	Skeletonize leaves. Control: Hand-pick into soapy water in morning.

Maturity

Flowering begins approximately 70 days after sowing.
