Growing Cut Flower Dahlias from URC with Dr. Alicain Carlson

Syngenta Flowers’ Dr. Alicain Carlson joins host Bill Calkins to discuss some key components of successful cut flower dahlia programs when starting from unrooted cuttings (URCs). Traditionally, most dahlia crops have been started from tubers, which were dug up and stored each year before replanting. Now, with beautiful dahlias available from URC, many growers are taking advantage of the benefits that come from this form of production. When buying from a reputable supplier, these inputs are virus and disease free with excellent uniformity across the crop, as well as simplified scheduling and potential cost savings. Dr. Carlson digs into the pros and cons of stating from URCs, as well as highlighting some key varieties in the Syngenta Flowers portfolio before moving into culture and production strategies.

Here's what you’ll learn throughout the discussion:

• Propagation tips for rooting into 50- or 105-cell trays
• Importance of long-day lighting in prop
• Rooting hormone trials and recommendations
• Why NOT to pinch young plants
• Winter dahlia production strategies
• Protocols for maximizing flower quality and “double-ness”
• Trial results from temperature research specific to dahlias
• How and when to perform a “hard pinch” after transplant
