Pinching and Growth Regulators
For pots 6" and smaller pinch at transplanting only. For hanging baskets and pots larger than 6" soft pinch at planting and trim around pot just prior to hanging. 5-10 ppm Sumagic or a B-9/Cycocel (2500/750) tank mix is effective. 500 ppm Florel on baskets and larger pots will promote branching.
Pest and Disease Management
General pest and disease practices as listed in notes. Calibrachoa are sensitive to pythium, phytopthera, and thelaviopsis. Maintaining proper pH (5.5-5.8) and good sanitation practices will help alleviate problems. Increased air circulation, proper water management and good soil porosity are also critical.
Scout regularly for aphids which can be problematic. Be sure to check hanging baskets that are hanging high, it can be easy to forget to scout for insect problems with pots high in the rafters.
Yellow growing tips is often an indicator of high pH.
Be sure to keep pH in optimum range. Cold is a good natural growth regulator.
