Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with cotyledons and first true leaves appearing within 7-14 days. Plants are delicate and require high humidity.

Maintain consistent moisture and warmth (70-75°F). Provide bright, indirect light. Use a seed mat for optimal germination. Avoid damping off by ensuring good air circulation.

2

Vegetative Growth

3-4 weeks

Seedlings develop multiple sets of true leaves and begin branching. Stems become more robust and the plant takes on a bushy form.

Thin seedlings or transplant to individual containers when 2-3 true leaves appear. Begin light fertilization every 2 weeks with half-strength balanced fertilizer. Maintain consistent moisture.

3

Pre-Flowering

2-3 weeks

Plant becomes fuller and more compact. Flower buds begin to form at branch tips. Foliage is dense and vibrant green.

Continue regular watering and feeding. Pinch back growing tips if a more compact shape is desired, though Blitz variety is naturally bushy. Ensure adequate light exposure.

4

Flowering

8-12 weeks (spring through first frost)

Abundant small flowers appear in solid colors or patterns depending on cultivar. Flowers continuously appear as older ones fade. Plant maintains lush foliage.

Deadheading is not necessary as Blitz is a prolific self-cleaning bloomer. Continue regular watering and weekly feeding with diluted liquid fertilizer. Maintain humid conditions in very hot, dry weather.

5

Late Season & Frost

Continues until first frost

Plant continues blooming until temperatures drop near freezing. Flowers and foliage may become sparse or damaged by cold.

In cool climates, plants will decline as temperatures approach freezing. May be brought indoors as houseplants if desired. Hardy only to zone 10 and warmer; treat as annual in cooler zones.

Avoid planting near:

Black walnuts (juglone toxicity) Dense tree root systems that compete for moisture

Common Pests

  • Spray with insecticidal soap or neem oil. Increase air circulation. Use yellow sticky traps for monitoring and control.

  • Increase humidity and mist foliage regularly. Spray with neem oil or miticide if infestation is severe. Avoid excessive heat and low humidity.

  • Allow soil surface to dry slightly between waterings. Use sand mulch on soil surface. Apply BTI (Bacillus thuringiensis israelensis) to soil if severe.

  • Remove with rubbing alcohol on a cotton swab. Spray with insecticidal soap. Quarantine severely infested plants.

  • No cure; remove and destroy infected plants. Control thrips which vector the virus. Choose virus-resistant varieties when available.
