Pinching and Growth Regulators

For all sizes of containers, pinch the liner 1–2 weeks after transplant; for containers larger than 6” and for hanging baskets, trim around the edge of the container as needed prior to spacing or hanging of the baskets.

Florel should not be used, stunting and flower delay will occur. 10-15 ppm Sumagic spray is effective on Summer Wave. Catalina should not need PGRs as they are naturally compact.

Pest and Disease Management

General pest and disease practices as listed in notes.

Grower Tips

-Bronzed foliage is likely indicative of too cold of temperature and/or too high of light.

Catalina is more compact than Summer Wave. Torenia prefers warmer temperatures.
