We’ve all been waiting for April and there is so much to do with cleanup, pruning, seed starting, division, transplanting, fertilizing, houseplant care…. Yikes! I find that making a list and prioritizing the tasks helps me to get things done.

Asparagus is the vegetable that lets us know spring has arrived. Once soil temperatures reach 50°F asparagus buds begin enlarging to produce the spears we eagerly anticipate. Here in Maine, it is one of the most popular early spring vegetables, appearing in our gardens and farmer’s markets in early May. Asparagus is a perennial crop, originating in Asia Minor and now grown throughout the world. It has been cultivated for more than 2000 years for culinary and medicinal uses and can be eaten raw or cooked, and is used fresh, frozen or canned.
Most commonly we think of asparagus as being green; however, “blanched” or white asparagus is created by keeping the emerging spears in the dark, preventing the development of chlorophyll. The white asparagus has a much more delicate flavor in addition to being more tender compared to green asparagus. Purple asparagus is also available in some farmer’s markets and as a variety to grow at home. Purple asparagus is generally thought to be sweeter than the green varieties. The purple color comes from the pigment anthocyanin, which masks the green chlorophyll. Be forewarned, if you steam or cook purple asparagus in water the result will be green spears. Anthocyanin is a water soluble pigment that is washed out. If you grill, roast or pan sear purple asparagus, it will retain more of its color.
The asparagus plant is composed of modified stems, called ferns, as well as a fleshy crown and an extensive root system. The spear — the portion of the plant that we eat — is an immature fern. The ferns are the photosynthetically active portion of the plant, which collect light and produce energy. The crown is a swollen underground stem or rhizome with two types of roots that are continually replaced: fleshy and fibrous. Asparagus should be planted in well-drained, fertile soil. The area around newly planted crowns should be kept weed free since asparagus does not compete well with weeds. Newly established planting should not be harvested in the establishment year or the following year in order to build and strengthen the crown.
Asparagus is harvested by snapping or cutting the asparagus just below the soil surface when the spears are approximately 6-8” tall. If you have only a small planting of asparagus, spears can harvest and stored until you have a sufficient quantity. Harvested spears should be stored upright at 35 to 40°F, with high humidity. When held under proper conditions, spears can keep for 10 to 14 days. Storage temperatures warmer than 40°F allow spears to continue growing, reducing sugars, and increasing toughness (fiber).

Fiddleheads are an iconic spring green that are a welcome addition to the diet after a long Maine winter. Fiddleheads are the emerging tightly-coiled frond of the ostrich fern, Matteuccia struthiopteris, and are found primarily along river and stream floodplains. A frequent question is: how do you tell which fern is the right one? This is an important question since research has shown that the bracken fern is carcinogenic. Three distinguishing characteristics of ostrich ferns are:
If a fern doesn’t have all three of these characteristics, it’s not an ostrich fern.
Research done by the University of Maine has shown that fiddleheads must be picked in moderation or the fern may die. Recommendations for a sustainable harvest are to pick no more than one half of the emerged fiddleheads from a crown, with no subsequent harvesting of later emerging fiddleheads in one growing season. Fiddleheads may be picked by just snapping them off below the coiled head, including the tasty stem, or may be cut with a knife, but if using a knife, take care not to cut into adjacent fiddleheads to be left.
Make sure to properly cook fiddleheads. Foodborne illness symptoms have been reported by people eating under-cooked fiddleheads. Details on proper cooking can be found in UMaine Extension’s Facts on Fiddleheads.
Fiddleheads are a valuable non-timber forest product that are increasing in popularity in part due to the local food movement. Because of their popularity, some fiddlehead grounds are now closed to picking due to over harvesting. Make sure you have landowner permission to harvest on other’s land, and share this information with those who do pick, so we can continue to enjoy this longstanding Maine tradition.

Background: Somerset County is the second poorest county in Maine with 18.6% of the population living below the poverty line.1 Children in the upper Kennebec Valley of Somerset County have few opportunities for low cost, supervised summer activities or camp experiences. In addition, communities in the Upper Kennebec Valley need fresh fruits and vegetables for their food cupboards or pantries because of the persistently high poverty rate. In Somerset County, 45.9% of children are eligible for free or reduced lunch and 37.3% receive SNAP (Supplemental Nutrition Assistance Program) benefits. This exceeds the state average of 26.7% and is the highest of any county in Maine.2 In addition, Somerset County has the highest poverty rate in Maine among seniors at 14.1%.
The goals of these gardening efforts were to use Extension research-based information and garden curricula to educate youth about gardening, increase access to fresh fruits and vegetables for low-income county residents, and develop youth’s community leadership skills.
Teaching Methods and Activities
To address the needs of youth and seniors, gardening activities were presented in informal settings with the help of Master Gardeners, community volunteers, 4-H program members, and Senior Companion Volunteers. A Master Gardener Volunteer and school staff member in Bingham, Maine, set up a gardening/recycling/leadership development program for two-week periods in the summers of 2009 and 2010. The program was called “Hutopolis” and engaged children in container gardening, square foot gardening, recycling, composting, and building with recycled materials. Local businesses contributed free recycled building materials and children designed and built their own “huts.” They planted and grew gardens, which they continued to care for after the two-week experience ended. Vegetables were used by their families and donated to the Bingham Food Cupboard.
In a second gardening effort, the Havin’ Fun 4-H Club, Somerset County Master Gardener Volunteers, and the Somerset County Senior Companion Program started a square foot gardening project at the Somerset County Extension Office in the summer of 2011 and expanded it in 2012. Two Somerset County Master Gardeners taught the club how to successfully garden and properly harvest vegetables. 4-H members replicated their square food garden at home and enjoyed the vegetables with their families. In addition, the Somerset County Senior Companion Program Volunteers received the vegetables raised by the youth and distributed the vegetables to low-income seniors in Somerset County.
Results and Impacts
The Hutopolis project incorporated experiential life skills science education: constructing a shelter, growing food, and re-using materials. Through this hands-on experience, the children acquired a deeper understanding of why community is important, diversity, and other cultural perspectives. In the words of a participating Master Gardener Volunteer, “The kids learned how to build, plant, and to work with one another, brainstorm, communicate, listen, and develop teamwork. It was awesome to watch the kids take ownership. They had something significant to do, something to care about, and opportunities to learn. I am happy to have shared in a piece of learning with them.”
Participants in Hutopolis returned throughout the summer to harvest, take home, and share their garden produce. They grew cucumbers, tomatoes, lettuce, green beans, corn stalks, and flowers. Green tomatoes were picked and taken home to ripen before the first frost.
The Havin’ Fun 4-H Club gardened in four small raised bed gardens. They harvested and weighed the produce weekly. The total after the final harvest was 278 pounds of food from 64 square feet. At $2.50 per pound, the food was valued at $695 and was distributed to low-income seniors. The 4-H youth learned the basic science of gardening skills by learning weed identification, season extension, and harvesting skills. They learned about the value of food and the needs of people in their midst who are food insecure. They also learned that they could be valuable and contributing members of their community by meeting with a few of the Senior Companions and hearing about the difference they made in the lives of seniors.
Here is a collection of quotes from Senior Companion Program vegetable recipients. “Those vegetables would have been very expensive! I wouldn’t have bought them. I received potatoes, beets, onions, zucchini, tomatoes, and pumpkins. I cooked and froze some of the vegetables in plastic bags so I could have meals in the winter. I also made pumpkin bread and pies. The small zucchini added to beaten eggs, flour, and butter, and then fried make like an omelet, and are very good. I also shared some of the vegetables with other seniors too. I hope to do more canning next year if I can get more vegetables! Please tell the 4-H thank you for the fresh produce.”
