“Raise your words, not voice. It is rain that grows flowers, not thunder.” -Rumi
Our farm here in the north is ready to batten down the hatches, it looks like the classic Humboldt County rains have begun. Puddles are forming, and it appears they are here to stay. Just east of here, our farm in
Willow Creek has had a dusting of snow and a few showers in the last week. To the south, our farm in
Oxnard is still enjoying a dry, windy autumn. Our farm in St. Catherines, Ontario, Canada has already been shoveling some serious snow, and at the farm in Baja, people are still wearing shorts…maybe they always wear shorts?
Here on the rugged north coast we are hardy people, many of which don’t even own a raincoat, while living in what is termed a “temperate rainforest.” The rain is essential to our ecosystem, which includes the tallest trees in the world and some of the most dramatic rivers in America.
Coho and Chinook Salmon are starting their amazing journey up the rivers to their ancient spawning grounds. About 2 miles from the farm, salmon are schooling up and preparing for the water levels on the Mad River to rise so they can begin swimming upstream, in some cases over a 100 miles, to reproduce. We are blessed here in Humboldt County with a stunning natural environment, and an
awesome community. This environment, although not ideal for suntans, air conditioners or sunglasses is perfect for growing
tulips,
lilies and
iris.
So what happens on the farm when the rain starts? Luckily, all our field crops have been harvested except our yummy
artichokes, which don’t mind the rain.
Our hoop houses are the most exposed to the elements. They don’t have much structure, just plastic sheeting stretched over arched metal poles. I asked grower Tim, “What happens to all the water that runs off the top of these hoops? It seems that you would need huge trenches to keep the water under control.”

Tim explained something you would never know without getting the inside scoop. When a hoop house is built on the farm, it isn’t just put up with metal stuck in the ground and the sheeting pulled over to cover it. Our team actually builds up the ground below the hoop house with about 3 feet of sand, and in that sand is a huge series of drainage pipes. This keeps the area well drained, water run-off is controlled and the flowers growing in the hoop house don’t get flooded. The main crops growing right now in our hoop houses are our
Royal LA Hybrid Lilies, Asiatic Lilies, Iris and
Freesia.

Our large complex of glass Dutch Greenhouses are where we grow the
Oriental Lilies and our
soil grown Tulips. These greenhouses have a steel infrastructure, thousands of glass panes, sliding doors and create a very controlled temperature atmosphere. When the rain comes; the humidity in the greenhouses spikes. A little humidity is great for the flowers; a lot of humidity is a recipe for disaster. A high level of humidity will encourage botrytis. Botrytis is the scourge of the flower farm. It is a fungus growth that will rot the stems and buds of lilies and turn them brown.

Grower
Antoon explained to me what they do to keep the humidity levels in check. The first thing they do is turn on the heat. Not your traditional heat, but a long series of white pipes through which they pump boiling water. This radiant heating system warms up the air in the greenhouse. Warm air holds more moisture than cold air, so the moisture which has accumulated in the greenhouse moves into the air, and away from the lilies and tulips. After a few hours of heat to pull the moisture into the air, the growers open up the vents on the greenhouse.
The hot, moist air rushes out of the greenhouse, rising into the sky, leaving the plants dry and safe from the devil botrytis. This clever system is repeated throughout the wet season and keeps our greenhouses producing year round lilies and tulips.
