This is a follow-up to my May article, Grow It Eat It Celebrates 15 Years of Teaching and Promoting Food Gardening! I visited a number of amazing Grow It Eat It (GIEI) projects and activities in 2023 that demonstrate its essential role in helping Maryland residents and communities become more food secure. 

So far in 2023, University of Maryland Extension (UME) Master Gardener Volunteers from 18 counties and Baltimore City worked 7,544 hours on GIEI projects, educating 10,125 residents! Here are some snapshots from the growing season.

GIEI demonstration plots and gardens allow for hands-on learning about new sustainable techniques. MG Volunteers in Montgomery County used “micro-mesh” insect netting to exclude insect pests, making insecticides (synthetic or organic) unnecessary.

Visitors and classes also learned how to use drip irrigation with a simple timer to water container plants automatically.

Signage at the Master Gardener Learning Garden at the State Fair helps new and experienced gardeners make informed decisions. MGs from Baltimore City and 12 counties had 3,617 direct educational contacts during the State Fair.

Home, school, and community gardens are essential parts of local food systems. Food gardeners collectively produce enormous amounts of produce, much of which is shared and donated. GIEI projects, classes, and demo gardens teach science-based information and practices, help connect gardeners to resources, and facilitate a shared, respectful learning environment. 

I have no doubt that more great work will be happening in 2024!

Grow It Eat It Celebrates 15 Years of Teaching and Promoting Food Gardening!

Maryland Grows2 Comments

Food gardeners are an important part of any local food system. In Achieving Sustainability through Local Food Systems in the United States (PDF) (2013), agricultural economists Dale Johnson and James Hanson, Ph.D. state: “By far the greatest, but often overlooked, local food source in the United States is gardening.”

About 35% of Maryland households are doing some type of food gardening and have lots of important questions: What’s this worm eating my kale? How do I improve my soil and test it for lead? How do I start a school garden? Where can I take a vegetable gardening class?

Since 2009 many residents and communities have received science-based food gardening answers and help from Grow It Eat It (GIEI)– one of the six major sub-programs of the University of Maryland Extension (UME) Master Gardener Program that teaches and promotes home, school, and community food gardening. This article serves to introduce this amazing program and some of its successes. I plan to write a second article later this year on some of the exciting 2023 GIEI projects from around the state.

What is GIEI?

Grow It Eat It was developed late in 2008 by UME staff, faculty, and volunteers in response to the Great Recession. Many people were already interested in trying their hand at food gardening as a way to eat more fresh produce and connect with nature. The economic collapse forced folks to find ways to reduce household expenses.

The main GIEI objective has been to increase local food production by combining the power of grassroots education and technical assistance delivered by field faculty and Master Gardeners, with UME’s digital gardening resources. Master Gardeners (MGs) have taught hundreds of classes, developed demonstration gardens, and helped thousands of individuals and groups start food gardens and learn and use best practices. Residents can learn about GIEI classes and events by visiting their local Extension web pages and connecting on social media. MGs also help residents solve food gardening problems at Ask a MG Plant Clinics around the state. The Home and Garden Information Center (HGIC) supports GIEI by training MGs, creating and maintaining digital resources, and answering food gardening questions through the Ask Extension service.

GIEI intersects and collaborates with other MG sub-programs– Bay-Wise Landscaping, Ask a MG Plant Clinic, Composting, and Pollinators– and with UME’s nutrition, natural resources, youth development, and urban ag programs. This helps the program address four of the five Strategic Initiatives guiding the College of Ag & Natural Resources.

As the faculty lead, I have loved every minute spent working with UME faculty, staff, and volunteers to shape, improve and expand the program. Master Gardener Coordinators and Volunteers decide how to best shape GIEI to meet local needs. The State MG Office organizes regular GIEI statewide planning/sharing meetings and continuing education classes, and provides seeds, teaching, and marketing materials. MGs responded to the pandemic by moving GIEI classes online. GIEI projects and activities steadily increased in 2021 and 2022 and should surpass pre-COVID levels in 2023.

Microgreens: Tasty Accents from Small Spaces

Maryland Grows3 Comments

My first response to microgreens was: “Why would I spend my time growing 3-inch tall plants to eat?”

Then I thought about all of the tiny leafy green plants (beet, lettuce, kale, basil, etc.) I had eaten over the years in the process of growing transplants at home and in greenhouses. And it started to make more sense: why not plant seeds closely in a container to just grow baby plants?

Benefits: When you eat microgreens you are ingesting the cotyledons, stems, and small expanded true leaves of edible plants. Some reasons to give them a try:

  • High in anti-oxidants and other health-promoting substances, like vitamin C, vitamin E, beta-carotene, and lutein
  • Can be grown year-round inside with strong natural light or inexpensive fluorescent tubes
  • Great for kids at home and in school- sow seeds, watch them sprout and grow for 10-14 days, and eat!
  • Wonderful assortment of colors, flavors, and textures

Claytonia, or miner’s lettuce

Maryland GrowsLeave a comment

I’ve grown a lot of different vegetables at this point, but there’s always something new for me to try. Last fall I planted some Claytonia perfoliata, or miner’s lettuce, alongside spinach in my vegetable garden. Both of them have wintered over nicely and are being harvested now.

Claytonia is a odd-looking small edible green plant.

That specific epithet “perfoliata” refers to the way the leaf is pierced by the flower structure. Each of those leaves is about the size of a quarter, so you need a lot of them to make a meal, but you wouldn’t want to overdo it anyway because they contain oxalic acid which is toxic in large quantities. (More than you would want to consume; don’t worry.) You can use claytonia in a salad, or briefly braise or wilt it in a cooked dish. It has a nice lettuce-like, slightly sour flavor.

The plant is native to the western U.S., and gets its common name from the California Gold Rush miners who ate it for vitamin C, to avoid getting scurvy.

I’ve seen claytonia seed for sale in a number of seed catalogs. Try planting it this fall for a spring treat next year. Definitely a cool-weather plant, it will bolt in the slightest heat, so overwintering seems the best way to go. I didn’t give it any protection at all, but if you live in a particularly cold climate you could try it in a cold frame.

Four-season lettuce

Maryland GrowsLeave a comment

One project we’re embarking on this year in the Derwood Demo Garden is growing lettuce year-round (or as close as we can get). Lettuce is a perfect crop for spring or fall: quick-growing, tolerant of cool weather, useful. But it often flags, turns bitter and bolts in hot weather, and heavy frosts will kill it.

The solutions to this are:

  • Grow in an area that gets more sun in the spring than in the summer – in the shade of a tree is great, or use shade cloth to alter the environment;
  • Choose varieties that suit the season;
  • Keep well-watered in hot weather;
  • Grow under a cold frame or plastic-covered tunnel in the winter.
Our salad tables are shaded by a large maple tree, so that’s where we will grow our summer lettuce. We’ve had success growing well into July before there, but haven’t systematically planned to keep going – it should work, though. We’ll try a few in the sunnier parts of the garden to see how they do, as well. And we’ll get the cold frame out for winter.
We’re starting our spring lettuces indoors for transplant.
Summer lettuces will be started directly in the salad table in part, plus we’ll start more seedlings indoors. We’ll use succession planting to start new plants every couple of weeks. If we are lucky with the weather and our varieties, we should be able to continue this through to fall, when more cold-tolerant lettuces will go in – some in the salad tables and some in the ground to be covered by a cold frame.
You can grow just about any lettuce for spring and fall. Some are particularly cold-tolerant and good for holding over winter. Here’s the list of varieties we’re trying for summer, all of which are supposed to be heat-tolerant and bolt-resistant.
  • Buttercrunch
  • Cherokee
  • Concept
  • Green Star
  • Muir
  • New Red Fire
  • Seafresh
  • Summer Bibb
  • Toretto
There are lots of other similar varieties out there, which we’ll try in subsequent years. This is a growing market niche, for obvious reasons – it’s hot out there, and we love our summer salads. We’re keeping track of which ones do best for us. If you have had success with summer-grown lettuce varieties, leave a comment – we’d love to hear from you.

Early Garden Chores

Maryland Grows2 Comments

I like Erica’s post about getting some garden chores done early.   And like her, I’m planting some early season cool weather vegetables seeds in the garden and getting some early weeding done.  But, unlike Erica, I am putting down my drip tape (see MG 6 Drip Irrigating Your Garden) to water the bed and covering the it with row cover to provide some frost protection for those emerging spinach and kale seeds.

Extended forecasts for our region (temperature and precipitation) show a good chance of above average temperatures and below average rainfall.  Of course, this could mean by a tenth of a degree or several degrees.  But when comparing the cost of a few seeds to some earlier than expected fresh vegetables for the table, I’ll always plant a few seeds early.

To my surprise, my arugula wintered over and my garlic looks great. My onion sets have been ordered as have my new red and yellow raspberries and new strawberry plants. After all this is the year of small fruit and there is nothing like fresh strawberries or raspberries from the garden

I’m also finishing up the rejuvenation of my 30 year old blueberry bed and will be pruning my trellised black raspberries in the next week or so.  Here are some before and after pictures.

Seeds started in the basement under florescent lights are broccoli, cauliflower, cabbage, lettuce, leeks, kale and fennel.  Toward the middle to end of March will be eggplant and peppers.  And just a reminder.  Fluorescent tubes start to lose some of there brightness (lumens) after about 15 to 20 percent of their life (20,000 hours).  So I change my fluorescent tubes out every two years (16 hours a day x 100 days x 2 years = 3200 hours or about 16% of the tubes expected life).  So if your seedlings grown under lights looked spindly and you had the tops within an inch of the lights, try changing the tubes.
