Calibrachoa

The Cruze series showcases extremely large, brilliantly colored flowers on a mounded plant form. These calibrachoa are ideal for 4- to 8-inch pots, hanging baskets and combination planters.

Recommended temperatures are 65 to 70° F days and 60 to 65° F nights.

Keep soil evenly moist for optimal growth and plant quality. Overwatering — especially during cool, low-light conditions    — will cause root problems. Maintain pH at 5.5 to 6.2 to prevent interveinal chlorosis, which may occur due to minor elements being limited in availability due to higher pH.

Use a balanced feed at 100- to 200-ppm nitrogen. Clear water irrigation may be necessary to maintain lower salt levels for controlled growth and maximum flower production. Fertilizer stock may require additional iron to maintain leaf color.

Calibrachoa will respond with earlier flowering by using night interrupted lighting or extending the day during short day seasons.

Plant growth regulators are usually not required. A Bonzi drench at 1 to 3 ppm and possibly Sumagic spray application of 10 to 20 ppm will control excessive growth.
