Germination Information
Pre-treatment: Cuttings: Cut into 20-30 cm lengths, 1 cm in caliper, treat with 2000 ppm liquid IBA, and struck in mist bed with bottom heat. Seeds: Scarify by hot water at temperatures of 176-194°F for 5-10 seconds, transfer to cold water, imbibe water for 1 day, then cold stratify for 90 days.
Establishment: Cuttings taken in early May had the highest rooting percentages. Roots are susceptible to excessive moisture; cuttings should be uppotted into a well drained media and carefully stored overwinter. Seedlings need excellent drainage, good air flow, and sunlight. Damping off disease and foliar diseases can be a problem with this species. Careful attention to irrigation frequency is needed during the establishment phase and should be done in the early morning so foliage can dry during the day.
