Tech Tips: To prevent tuber formation you must provide at least 14 hours of light and you must not let temperatures fall below 55 °F (13 °C). Short days and/or cool temperatures will drastically stunt growth.

B-Nine ® (2500 ppm) can be used to control growth. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® (1500 ppm) can also be used to control growth and improve branching early in production, especially if not given this treatment in propagation. A Bonzi ® drench (0.5–1 ppm) can be given 3–4 weeks before finishing and results in toned, high quality plants.

Mexican Gold ™ Semi-Double 70018302 E Tech Tips: Mexican Gold cuttings root quickly and should be transplanted on time. Plants are moderately vigorous and early flowering, and will fill out containers quickly. Mexican Gold forms a well-branched, mounding to semi-trailing plant with just one pinch. Gold Compact will take more time to fill out pots than the other varieties (Gold, Gold Jumbo, and Gold Semi-Double). These are great plants for mixed containers and the flowers mingle well with other species. M

M Tech Tips: Varieties vary between single and semi-double type flowers. Plants are relatively fast growers and fill containers and baskets quickly. Caleo Calendulas tolerate a range of temperatures and growing conditions. However, the best plant quality occurs when plants are grown under relatively cool temperatures and high light intensities. Extremely high temperatures will result in reduced flower size and more open habits. Caleo was bred and selected for Powdery Mildew resistance, but plants should be inspected periodically under high disease pressure.
