Reducing temperatures during finishing (RTF) can reduce energy and input costs when producing poinsettias. Check out research from Purdue University and University of New Hampshire on how RTF influenced plant height, bract area index and time to marketability and first pollen shed.
Finicky yellow petunias require ample nutrition through aggressive fertilizer use during propagation.
As I talk to growers around the country, I often find that there is confusion between (1) photoperiodic lighting used to create a long day for flower induction of long-day plants and (2) supplemental lighting used to increase the total quantity of photosynthetic light received over the course of the day, which is referred to as
Research at Purdue University is determining how LEDs, providing light of different wavelengths, compare to traditional high-pressure sodium lamps.
Cuttings of vegetatively propagated bedding plants are frequently rooted in late winter and early spring to meet the spring and early summer market demand for flowering bedding plants. However, this is also the time when dirty and old glazing material, interior superstructures, and hanging baskets suspended above benches reduce already seasonally low ambient outdoor daily
Managing all the different environmental and cultural aspects of greenhouse crop production can be an intimidating and daunting task, especially during the peak production season. But it’s necessary to produce a high-quality, salable plant. The greenhouse is full of moving targets, from root zone pH and EC to plant growth, air temperature and light. Managing
Have you considered replacing perlite with whole parboiled rice hulls (PBH) or peat with ground PBH in your growing substrate for finishing spring bedding plants, but are not convinced they are an effective substrate component? Alternative substrates are a hot topic, as many growers are looking for more sustainable growing mixes, lower production costs and
It is fairly common for substrates used in cutting propagation to be comprised of sphagnum peat moss and perlite or other materials. While there is no doubting the usefulness and effectiveness of peat and perlite as substrate components, some growers are looking for alternatives. Propagation substrates do have particular requirements compared to mixes used for
This is the second article in a two-part series looking at the effects of light during cutting propagation. While the first article focused on the effects of daily light integral (DLI) during propagation of rooted cuttings, this article will focus on finished plants. We wanted to see how DLI during propagation affected growth and flowering
Whether you are a propagation specialist or are rooting cuttings for your own in-house production, the goals of propagators are the same — to efficiently produce high-quality rooted cuttings. In order to meet the spring and early summer market dates for flowering bedding plants, cuttings are typically rooted in mid- to late-winter and early spring
