Calibrachoa

Conga is an all-new compact series of calibrachoa featuring four bicolors. These varieties work well in pot-tight programs with no pinch or plant growth regulators. Use a well-drained, soilless medium and maintain pH at 5.4 to 5.8. Media should be routinely tested every 14 days or when early signs of elevated pH become visible. Recommended temperature is 50 to 58° F nights and 71 to 76° F days. High temperatures will cause poor branching, unwanted stem stretch and reduced flowering.Keep light intensities at 5,000 to 8,000 foot-candles. Low light levels cause stem stretch and poor flowering. Flowering is best under long days of spring and summer. Generally, flowering will begin in mid to late spring and will be heaviest in late May to September.Plants are susceptible to root diseases if over-watered. Allow the media to dry slightly between watering, but avoid any wilt. Provide plants with adequate air flow at all times.Caibrachoa require heavy fertilization. Use constant feed with a balanced fertilizer at 225- to 300-ppm nitrogen with additional iron as needed. A full complement of minor elements should be provided. Use clear water with every third watering if high soluble salt problems occur.
