Tech Tips: Keep the pH down in the mid 5.0s to avoid tip yellowing—drench with iron chelate if necessary. Avoid overwatering of young plants. Plants can be pinched twice on baskets and larger containers (once in prop, once after transplant). An early Florel ® or Florel ® + B-Nine ® WSG spray improves branching. Mid-season Bonzi ® drenches are the key to beautiful mounded baskets. Watch for aphids. High DLIs and moderate-to-cool finishing temperatures produce high-quality calibrachoas. Use proper sanitation when pinching or shearing calibrachoa to prevent possible virus spread. Calocephalus WHIMSY ™ Calocephalus brownii MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM pH: 5.8–6.2 SME 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm 4,000–6,000 foot candles Day neutral 70–72 °F (21–22 °C) 62–64 °F (17–18 °C) 125–175 ppm N 1 Pinch 1 pt. | 1 ppp | 4–6 weeks 1 qt. | 1 ppp | 4–6 weeks 1.25 qt. | 1 ppp | 4–6 weeks Tech Tips: Whimsy calocephalus is a compact plant that has low water and fertilizer requirements. Use plastic tenting or Reemay ® fabric during propagation if needed to keep high humidity, and to minimize excess water on the foliage. Provide moderate to warm temperatures early on after transplant to get the plants established. Avoid over-saturated media and overly cool temperatures. Whimsy may form bright yellow flowers on very mature plants, but its main value is its unique silver foliage.

Provide moderate to warm temperatures early on after transplant to get the plants established. Avoid over- saturated media and overly cool temperatures. Helichrysum italicum may form golden yellow flowers on very mature plants, but its main value is its unique silver-colored foliage. Trimming plants is the best way to control growth.

Tech Tips: Long-day lighting (daylength extension or night interruption) is needed during propagation to avoid premature flowering and tuber formation. The ideal photoperiod during finishing to provide the correct balance between vegetative growth and flower formation is between 13-14 hours. Growing under very short natural days (< 12 hours) will result in short plants, fast flowering, and root tubers. Provide warm temperatures early on in finishing to allow plants to establish after transplant. Cut flower dahlias grow best under moderately warm temperatures. Avoid extreme heat stress, especially under relatively high light intensities. Scout and treat for a range of insects and diseases, including spider mites, thrips, and powdery mildew.
