How to Grow Calibrachoa Kabloom Purple

Tiny seed germinates with cotyledons emerging. First true leaves appear as growth accelerates.

Keep soil consistently moist but not saturated. Provide bright light and maintain 70-75°F. Thin seedlings if overcrowded. Begin fertilizing at half strength once true leaves appear.

Plant develops branching stems and robust foliage. Compact, bushy form begins to establish. Multiple growing points develop.

Pinch growing tips once or twice to encourage bushier, more prolific growth. Gradually acclimate transplants to outdoor conditions. Water consistently and feed with balanced fertilizer weekly at half strength.

First flower buds form and open along branching stems. Purple flowers begin creating visible color.

Transition to full-strength fertilizer if not already. Ensure adequate sunlight for best color development. Continue watering deeply but allow brief drying between waterings. Remove any dead or diseased foliage.

Massive profusion of purple trumpet flowers covers the plant. Dense, mounding habit fully achieved. Flowers cover most foliage.

Kabloom varieties require minimal deadheading due to continuous bloom genetics. Water deeply 2-3 times weekly depending on heat. Feed every 7-10 days with flowering fertilizer (higher potassium). Remove yellowed lower leaves if desired for tidiness.

Flowering slows as temperatures drop below 55°F. Plant growth and bloom production diminish. Frost damage occurs at 32°F or below.

Reduce watering as growth slows. Stop fertilizing. In zones 9-11, cut back by half and provide winter protection for potential spring regrowth. In cooler zones, compost spent plants after first frost.
