B-Nine ® WSG (3,500–5,000 ppm) can be used. Sprays of Configure ® (300 ppm) or Atrimmec ® (200–400) early on can be used to improve branching. Bonzi ® drenches (0.5–2 ppm) can also be done to control growth and reduce leaf size, especially under very hot growing conditions.

Tech Tips: Madinia Maximo dipladenia are very slow rooters. Provide ample heat and rooting times during propagation. Plants are also chilling sensitive so avoid storing cuttings<48 °F (9 °C). Madinia Maximo has a controlled growth habit and bred for improved branching. They make very nice quart products. An early pinch (either in propagation or shortly after transplant) will encourage branching. High light and warm temperatures will improve quality and help reduce crop times. Higher light intensities and longer photoperiods help reduce the natural vining of the plants.

Not needed. Control by pinching if needed.

Tech Tips: Mezoo is a trailing succulent-type vine that makes beautiful baskets and combo plantings. It is a relatively slow starter and is best grown warm to get it established and growing. Under high light, it will develop small colorful red flowers that add character to the plant. This is a very tough plant that grows and performs under a range of environmental conditions.

B-Nine ® WSG (2,500 ppm) can be used. Drenches of Bonzi ® (1–2 ppm) or Sumagic ® (0.5–1 ppm) also work well to control growth or to hold plants before sale. Plant size can also be controlled by pinching.

E Tech Tips: Stick unrooted cuttings immediately to reduce bottom leaf yellowing and drop that can occur if cuttings are held for too long. Euphorbia is very sensitive to ethylene damage during shipping. Euphoric is a slow starter both in propagation and finish, but grows quickly when established and growing under warm temperatures. High light and warm temperatures will improve plant quality and reduce root diseases. If grown too cold and wet, fungal root can develop. Plants can be trimmed to shape at any point during production. Bonzi ® drenches work well to control growth mid to late in the production cycle.

Florel ® can also be sprayed at 350–400 ppm early in the crop cycle, especially for larger pots and baskets, to improve branching and control growth. A Bonzi ® drench (0.1–0.25 ppm) can be used at the end of production.

Tech Tips: Caldera is relatively vigorous and requires regular PGR applications, especially under warm growing conditions. Provide relatively high light levels and warm temperatures early on to establish the plant and to allow it to respond adequately to PGRs. Early Florel ® sprays are key in making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH between 5.5–6.0 to avoid iron deficiency (tip chlorosis).
