PERSPECTIVES | BY MATTHEW LEHMANN
Irrigation at a large
container farm
When I started working at Bailey Nurseries, I
was blown away by the size of the operation. The
bulk of my prior experience was working at a
much smaller production facility where we hand
watered containers of annuals, perennials and
shrubs. This gave me a great foundation on the
principles of plant water requirements.
Fast forward to my career at Bailey Nurseries,
where I work at our container facility in Illinois.
We are growing fields and fields of perennials and
shrubs in containers, mainly 2 gallons. At peak, we
can have one million containers on the ground. Watering
is accomplished using overhead sprinklers, four
100-horsepower pumps and a wireless radio controller,
all working in conjunction to move over two million
gallons of water every day. No hand watering here!
Since we are operating on a large scale, there's a lot of
planning to make sure things go as smoothly as possible.
This includes making a new watering schedule every day
for the following day. That schedule is distributed to our
irrigation staff and field supervisors allowing them to see
what lines are coming on and when. This helps them plan
the day for their crews.
There are many things that affect what we water and
when we are watering it. Varieties, crop stage and weather
are the biggest factors. For example, varieties of cornus
use a lot of water during the growing season but once
the temperatures start to decrease they require very little
water. Then, at the end of the season, they need to dry
down some as they don't tolerate wet roots throughout
the winter.
I also work closely with our production department to

technologies to improve

and efficiency in

help group varieties of plants together that have similar
watering requirements. This is especially important when
we start growing new varieties. Sometimes, it takes a
little trial and error to figure out the best placement for a
new variety.
Over the last few years, we have implemented different
technologies to improve our effectiveness and efficiency in
irrigation. We have weather stations at various locations
around the farm with built-in cellular modems allowing us
to monitor conditions in real time. When a storm comes
through, we can see exactly how much it has rained. This
helps us determine if we can decrease our run times or
turn the irrigation off completely for the day. We also
use wind data to determine how many pots may have
blown over to help decide staff needs for resetting plants.
Having this data available immediately allows us to make
decisions right away, even if we are off-site.
