Peggy really wanted to grow food but she wasn’t sure if she had the time or the place. We were meeting over Skype for a coaching session and I was trying to inspire her to just get growing.
“Grow a sprout overnight, a micro-green in a week or a radish in a month,” I said with a grin. “It’s so simple!”
Peggy was ready to give greens a try in her small apartment because she wanted home-grown edibles ASAP. Sprouts are the speediest but micro-greens take less than a week from seeding to eating and they look more like real food. And if she had more time? I suggested she grow radish – it only takes a month.
A garden in the traditional sense is too far off for Peggy, especially in Canada in February
when we are months away from outdoor gardening. With fingers twitching and green thumbs fading, Peggy wanted to get growing. So I prescribed micro-green pea shoots. All she needed was a few seeds, an open plastic tray, potting mix, and a heat mat.
Seed left over from last year’s garden is good enough. You can also buy special seed at Mumm’s Sprouting Seeds. The plastic plant tray is probably in your shed or garage, left over from last year’s bedding plant season. Whatever you use, make sure it has drainage holes in the bottom.
I recommend filling the tray with moistened, sterile potting mix such as Pro-Mix instead of real soil. I’ve seen seeds rot and mildew when grown in compost or garden soil. In fact to prevent disease it is best to use clean, sterile soil for each batch planted. All the energy needed for greens is in the seed, but disease can cling to the flats or soil. I fill the flat with 3 cm. (about an inch and a half) of new potting mix and generously sprinkle the seed in a fairly thick single layer. Then I spread additional soil to cover the seed and water well so the soil is completely saturated.
I use a “diaper” under the soil-filled tray so the water doesn’t pour out as soon as it is added to the standard 28 by 44 cm. (11 by 17 inches) plastic tray. A layer of felt or section of newspaper makes a great diaper and stops the flooding.
Once excess water is drained away, I place the flat on a heating mat such as the Jump Start heating seed mat. If you have a grow light or an in-floor heating system (as is common in Canadian homes) you can start seeds on top of the lights or warm floor instead of on the special mat. Seeds will sprout in a day or two like regular sprouts. In six days micro-greens are tall, tasty, and edible.
For traditional seed starting I generally use a four-foot bank of lights. The stacked lighting is a fabulous luxury, if you can afford it, but only if you are going to get serious about growing salads. If you just want a few micro-greens to add to store-bought salad mix, you can do without lights.
The mistake I first made growing micro-greens was to put them under grow lights. This kept them short and stocky. This is fine if you’re starting full-sized plants for the garden but they were so short they were hard to cut as greens. As soon as I balanced the trays on top of my bank of lights instead of under them, my luck and my crop changed. The roots were warmed by the lights below them while the stems were forced to reach for the light. With this change the micro-greens looked just like the sprouts I saw for sale at the market – tall, delicate, and thin. Who doesn’t want to grow something that looks as good as store-bought?
Not long ago I wrote about this on my website. When I was getting photographs taken for my page I forced Dan, my photographer, to try a bite of some pea greens I had grown for the photo shoot. He winced. Pulled away a bit. But I pushed them up to his mouth. He was forced to take a bite.
“Mmm, that is good. It tastes like green peas.” Not surprisingly, onion microgreens also taste like onions and kale greens taste like kale.
As you dream of spring, you can enjoy the taste of summer if you start growing micro-greens on a regular basis. Depending on the size of your family a tray of greens might be enough for a week’s worth of salads. My coaching student Peggy decided to start with half a tray because she lives alone.
It is great to keep the rotation going by starting new seeds again in a second tray the day you start harvesting the first batch. Then, like Peggy, you can grow food even when the outdoor temperatures are frigid and nothing inspires you to step outside.

My goal when starting a container garden design business ten years ago was simply to earn enough money to put our two children through college. My husband was earning a healthy paycheck in the IT industry so I had the luxury of accepting or declining clients as whim and inspiration called. However, after a series of injuries, I realized that this physically demanding career was going to be short lived. I needed to diversify – fast.

It therefore makes sense for me to spend more time sending out a newsletter every month or quarter (with plenty of calls to action and links to buy services and products) than I do writing informative but non-income generating blog posts.

Outside there’s a garden photo opportunity pulling at me. A section of lettuce transplants that I covered with a worn out piece of fiber row cover is doing much better than the plants on the side that didn’t get covered. My camera is currently outside, acclimating to the temperature/humidity of Texas so I won’t be frustrated with a fogged lens when the time comes to snap photos of that lettuce.
the perspiration flows more freely when I’m trying to capture a clean, creative photo than it does when I’m hoeing weeds. I remind myself, “Look, and look some more before you click the shutter because fixing it in Photoshop is a pain in the A—.” But I have to admit that digital photography is wonderful and pixels are cheap. One SD card can last me for months, if not years.

However the date change to early December did not make sense for the landscapers, designers, and garden center workers who were all at the height of their Christmas decoration craziness! Many of those landscape professionals simply could not get away at this busy and lucrative time of year to go to an industry show in Boston. As a result the show floor was stocked with heavy equipment but other categories appeared to be under-represented this year.

When he arrived in Arizona in 1969, Ron took on the challenge of finding plants suitable for Southwest landscapes. That same year he founded Mountain States Wholesale Nursery (MSWN). His goal was to find native and arid-adapted plants with improved flowering, larger blooms, and less maintenance. Over the years this nursery has become a preeminent grower and developer of arid-adapted plants.
Nicholas Staddon, serving as our host. Members shared with each other the challenges and joys of being a garden communicator in the Southwest. We agreed that people are expressing more interest in gardening. People see it as a way to enrich their lives while benefiting the earth as they focus on growing native plants or plants adapted to the regional climate.
After the field tour we strolled through collections of plants that were introduced by MSWN throughout their 47-year history. Then we enjoyed lunch underneath white tents. Conversation flowed freely between landscape professionals – except for the occasional interruption of F-16 fighter jets from the Air Force Base next door.
