Temperature and light intensity have greater impact on flowering, especially during Winter and early Spring. Jolt will benefit from being grown under high light levels and is a facultative/quantitative long-day plant. It can flower under different daylengths, but will take slightly longer to flower under short days than long days. A small percentage (up to 3%) of early off-types can be observed with Jolt dianthus at 4 to 5 weeks from sowing. These plants should be removed/discarded at transplant. JoIt Purple is more sensitive to paclobutrazol than others and the rate should be reduced to half of others.

Grows best in warm and dry conditions. Use light feed. Rinse foliage after feeding to avoid salt burn.

Pinching not recommended. For height control, use daminozide as needed.
5"/6"/1 Gallon/15 cm , 1-2 (ppp), 5-8 (weeks), Spring, PGR daminozide 2,500-5,000 ppm Spray 8"/2 Gallon/20 cm , 2 (ppp), 6-8 (weeks), Spring, PGR daminozide 2,500-5,000 ppm Spray
Do not grow plants at temperatures below 62°F (16°C). Stretched plugs can be planted deep for better habit management. Pinching is not necessary. Daminozide may delay full flowering, but it is helpful early on in developing good branching. If starting with a daminozide spray for habit management, consider a paclobutrazol spray (10 ppm) or a low rate drench (1-2 ppm) to finish. Warmer temperatures and higher light levels can significantly reduce crop times. Do not grow plant at temperature below 62°F (16°C). Stretched plugs can be planted deep for better habit management. Pinching is not necessary. If starting with a daminozide spray for habit control, consider a paclobutrazol spray or low rate drench to finish. Daminozide may delay full flowering, but is helpful early on in developing good branching. Warmer temperatures and higher light will significantly reduce crop times. Crop time can be influenced by light levels; i.e., when grown in areas with low light levels or during period of low light intensity, crop time could be approx. 3 weeks longer. Plant Growth Regulators: If needed, use B-Nine/Alar (daminozide) at 3,500 ppm (4.2 g/l of 85% formulation or 5.6 g/l of 64% formulation) to tone the crop. One application at 2 to 3 weeks after transplant will be sufficient. May be grown cooler (50°F/10°C minimum) with additional 2 to 3 weeks crop time. High light, spacing and cooler temperatures will reduce stretching. A paclobutrazol drench at 4 to 10 ppm, 2 to 3 weeks after transplant, is commonly effective in controlling stretch. Paclobutrazol sprays may follow the drench to maintain plant structure.

Do not overwater and avoid watering plants late in the day, as constant wet foliage may make the plants susceptible to Botrytis. Does not require pinching.

TEMPERATURE: Growing under temperatures below 60°F/15°C for the first 6 weeks after transplanting is essential for uniformity of flowering. Warmer temperatures could significantly delay flowering and cause flowers to not be uniform. MOISTURE: Heuchera prefer average moisture levels. They do not tolerate overly wet or overly dry conditions. Do not allow the plants to dry out between waterings. Under high light intensities, marginal leaf burn may occur if the plants are grown too dry, with too low of fertilisation. PGRs are not needed. Grow cool and ensure an active climate.
