Well-drained soil. Dislikes wet Winter soils. Monitor for Aphids. Cold growing at 55°F (13°C); add 4 to 5 weeks crop time. See GrowerFacts for more details on overwintered production. 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. Do not plant plugs too deep. Keep plug surface at the same level as the media surface. Avoid wet and overly dry. Needs well-drained medium.

No - vernalisation not needed when sold for foliage

Do not plant plugs too deep. Keep plug surface at the same level as the media surface. Grow relatively dry. Needs well-drained medium.

Annual , 4"/4.5"/Quart/10 cm , 1 (ppp), 10-13 (weeks), Summer PGR daminozide/chlormequat chloride tank mix 750-2,500 ppm Spray Annual , 5"/6"/1 Gallon/15 cm , 1 (ppp), 10-13 (weeks), Summer PGR daminozide/chlormequat chloride tank mix 750-2,500 ppm Spray

No - damage to plugs results below 41°F (5°C)

Does not need pinching. Maintain media in high moisture. Growing plant too dry will result in flower bud abortion. Monitor for Thrips, Aphids and Spider Mites. Growth stops and lower leaves turn yellow when grown below 68°F (20°C). In Southern climates, stronger PGRs may be needed; option is paclobutrazol 0.5 ppm drench. High light will promote branching and reduce plant height. Spacing when plants touch each other is highly recommended.

Overwinter , 4"/4.5"/Quart/10 cm , 1 (ppp), 26-36 (weeks), Early Spring

Yes - minimum 8 to 10 weeks. Plants should be bulked for about 8 to 10 weeks before being receptive to cold treatment.

No pinch needed. Allow enough bulk time; grow in active climate. Monitor for Downy and Powdery Mildew; spray preventively.

Annual , 4"/4.5"/Quart/10 cm , 1 (ppp), 9-10 (weeks), Summer, ADT 60°F (16°C) PGR daminozide 2,000-3,000 ppm Spray Annual , 4"/4.5"/Quart/10 cm , 1 (ppp), 9-11 (weeks), Late Spring, ADT 60°F (16°C) PGR daminozide 2,000-3,000 ppm Spray Annual , 5"/6"/1 Gallon/15 cm , 1-3 (ppp), 9-10 (weeks), Summer, ADT 60°F (16°C) PGR daminozide 2,000-3,000 ppm Spray Annual , 5"/6"/1 Gallon/15 cm , 1-3 (ppp), 10-11 (weeks), Late Spring, ADT 60°F (16°C) PGR daminozide 2,000-3,000 ppm Spray

Avoid planting plug too deep. Keep plug surface same as medium surface. Grow low RH and high light. Let top soil dry in between waterings, but do not allow medium to dry, as high EC could cause root damage. Monitor for Botrytis, Root Rot, Leafspot, Aphids and Mites. For shipping, keep soil moist and plant dry. Use Avignon Early Blue for annual early Southwest and Northwest season and Ellagance Purple for annual early Southeast season. Lavance is best for Summer production, has best bulk. Do not plant this variety for early season. Growth is delayed in cool conditions. See the Lavender Scheduling Tool at panamseed.com for finishing schedules by region. For overwintered production, cut back just below top foliage; do this mid-Autumn, approximately 4 weeks before dormant period, or in Spring just before regrowth.
