Poinsettia Production: 3 Steps To Healthy Roots
There are numerous times during a poinsettia crop that things can go wrong, but perhaps the most overlooked time is the period from when a cutting has rooted until the plant is established in the final container. During this time, roots can be lost and then the plant never grows at the normal rate in September and October. This article focuses on the critical establishment of a healthy root system during August, so your poinsettias will be uniform and vigorous during the vegetative phase of growth prior to flower initiation in mid to late September. Our primary goal is to help you establish healthy roots, because root loss shortly after transplant is common with poinsettias. Diagnosing the cause of root loss can be difficult. There are three main factors that contribute to healthy roots: 1) fungus gnat management; 2) pythium prevention; and 3) proper watering. Fungus Gnat Management Fungus gnat […]

Temperature management is the predominant factor that impacts the post-harvest performance of horticultural crops. Over the past several years, we have been working with cutting suppliers to improve the reliability of delivering unrooted cuttings that perform well in propagation. Inevitably, all roads lead back to temperature management. Cutting performance relies on strong cold-chain management. The strength of a chain depends on each of the individual links from the time of harvesting the cutting until the cutting is stuck on a propagation bench. This article will discuss why temperature management is so important and will provide guidelines for growers for handling boxes of unrooted cuttings. Post-Harvest Physiology 101 Temperature is so critically important because it directly affects physiological processes such as respiration and ethylene production. Let’s take a moment to review some basic post-harvest physiology principles. Respiration is the process by which carbohydrates (sugars and starches) are broken down into carbon dioxide. […]

Finishing Poinsettias Cooler
High fuel costs have our industry searching for opportunities to lower the thermostat, and poinsettias provide a unique opportunity for reducing greenhouse fuel inputs. Initially, the options may appear to be limited since poinsettias have historically not grown well at cooler temperatures. However, poinsettia has several attractive features. First, the scheduling and marketing calendar is identical from year to year. This makes it easier to compare data from previous years to determine how a current crop is progressing. Second, cooler temperatures can be compensated for by adding time to the front of the schedule. This is not usually a problem since greenhouse space is often available during the summer. Third, several new cultivars are extremely early to flower and thus a one- or two-week delay in flowering may be ideal for hitting the peak market dates. In 2006, experimental trials were conducted at four greenhouses situated in different parts of the […]
