4"/4.5"/Quart/10 cm , 1 (ppp), 6-7 (weeks), Spring
5"/6"/1 Gallon/15 cm , 1 (ppp), 5-6 (weeks), Spring 5"/6"/1 Gallon/15 cm , 1 (ppp), 6-7 (weeks), Summer
Don't grow too wet. This can cause root rot and black foliage. Stretching of plants can be avoided by using damonizide and chlormequat.
4"/4.5"/Quart/10 cm , 1 (ppp), 6-7 (weeks), Spring 5"/6"/1 Gallon/15 cm , 1 (ppp), 7-8 (weeks), Spring
4"/4.5"/Quart/10 cm , 1 (ppp), 10-11 (weeks), Spring 5"/6"/1 Gallon/15 cm , 3 (ppp), 10-11 (weeks), Spring
Best in tropical and semi-tropical climates. For cooler (Northern) growing areas, add 3 weeks to crop time or grow for Summer sales.

Drench with a fungicide at transplant. Use growing media with excellent aeration. It does not perform well in dense soils. Do not overwater the plants. Provide high light to avoid stretch. Low light levels will reduce branching.
Cuphea is very vigorous and temperature sensitive. Growing cool can reduce PGR needs. Conversely, growing above 73°F (23°C) may need higher PGR rates or additional applications. Adjust based on your conditions. No pinch needed; if you choose to pinch in young plant stage, follow with 2 to 3 treatments of paclobutrazol spray at 20 ppm. Flowering is delayed by ~3-10 days under LDs, depending on the variety and growing environment. Cuphea is sensitive to ethylene, so take proper precautions when shipping. Very responsive to daminozide. Also responsive to day/night temperature differential (DIF), and plants are shorter with a negative DIF. Grows best under high light intensity (DLI≥10 mol·m¯²·d¯¹) and cool nights. Under low DLI and shorter daylength, crop time will be delayed by 2-3 weeks. Dianthus Coronet timing is also influenced by temperature. An increase in ADT from 60°F to 67°F decreased flowering time by 3 weeks. Strawberry and White Purple Eye are more compact and can use half the rate or no PGR. Dart will benefit from being grown under high light levels for promoting plant branching and flower colour and quality. Plants grow bigger and fill pots easier under higher DLI. Providing high light will also keep plants compact and will reduce the need for PGRs. Plants will develop faster and will be earlier to flower when Dart is a naturally compact plant. Responds well to paclobutrazol (bonzi) when necessary. temperatures increase. Total crop time will be around 2 weeks faster when average day temperatures change from 62°F/16°C to 68°F/20°C. Dart can be grown cool in outdoor containers, field or in cool tunnels after transplant at 40°F/5°C night temperatures. Greenhouse production is possible as well. Avoid Summer finishing. Plants will develop very fast due to high temperatures and stay much more compact. Example: To fill a 5"/6"/Gallon/15 cm, 1-2 ppp are necessary. Autumn finishing is possible as well. Plants will finish faster because of higher average day temperatures. For southern areas with mild winters, Winter and early Spring production can be done as well. Lower average day temperatures increase flower shelf life. Pinching is not required or needed. Dash dianthus has a naturally compact plant habit and good basal branching when compared to other barbatus-type dianthus, making it more suitable for container production. Provide 65 to 75°F (18 to 24°C) day temperatures and 60°F (15°C) night temperatures for the first 2 weeks of greenhouse production to establish the plants. Finish at 60 to 70°F (15 to 21°C) days, with nights in the low 50°Fs (11 to 12°C). Lower temperatures can be tolerated as plants mature.
