the last 25-30 years was when companies supplying domestic growers moved to

programs such as tissue culture, but in terms of how the cuttings are handled
very few changes have occurred.”
began to do offshore propagation, chief operating officer Steve Rinehart began
to ask what the company could do differently in regards to handling vegetative
cuttings that were pre-stuck, that could be placed on the bench to root and
have the same results if they stuck the cuttings themselves without having the
labor costs and production input costs,” Williams said. “We have been working
with a company for about eight years to develop different kinds of packing
materials that could be used with offshore cuttings. Two years ago we
introduced the Ecke SNAP System™ (http://www.ecke.com/ecke/?page_id=1042) that
consists of a packing material for offshore callus cuttings that acts as a
rooting medium once the cuttings arrive here in the United States.”
System the company started by trying to merge packing foam with a growing
said. “We worked with a number of different iterations of this product to get
to a material that we were satisfied with. The most important factor was once
the cuttings arrived on shore we wanted them to root well. The Ecke SNAP System
provides a really good environment for root development. There is a lot of
porosity, good water-holding capacity, but also good aeration.”
Geraniums, poinsettias and spring annuals are stuck in a different medium prior
to being packed in the Ecke SNAP System.
Williams said. “Each variety has a different callusing time, usually anywhere
from 10 days to two weeks. Once the callus is established the cuttings are
removed from the medium and placed in the SNAP packing material.”

the cuttings and packing material to be as clean as possible.”
callus cuttings offshore is a quick process. For most customers there is
usually a 36-hour turnover. When a SNAP System order arrives at a customer’s
facility, they receive three strips of 26 cuttings in a tray that holds 78

most challenging part of propagation for many growers is the first two weeks
typically for most crops. During this time they require the most heat, the most
intensive care. With the SNAP System that part is done offshore. Growers save
two weeks of propagation and the inputs that they would require during those

planted, placed in the greenhouse, and then they move right into the next two
weeks of rooting. Typically during the two weeks that the callused cuttings are

final rooting stage. We are trying to eliminate as many of the variables as

the medium.” Williams said. “This commonly occurs with poinsettias because
growers are sticking cuttings during the hottest time of the year. The SNAP
System can provide a little more flexibility preventing the area around the
base of the stem from becoming oversaturated. Also, growers who are doing
direct stick with poinsettias can’t afford to fail because they are typically
on a tight schedule.”

rosemary, these plants can have issues sticking them as unrooted cuttings,” he
said. “We can harvest the cuttings and stick them offshore and once they are
callused they don’t have that same sensitivity to shipping. The SNAP System is
also enabling us to look at some crops that in the past were difficult to root
or ship. With the SNAP System we can look at those crops again because this system
may eliminate some of those issues and allow us to add them to our offerings.
