GARDEN REVOLUTION TALK IN SHARON

If you care about your chickadees, what do these numbers mean: 350 to 570? My environmental and social justice pal Ellen Schoenfeld-Beeks let us know at her “Garden Revolution” talk at the Unitarian Church of Sharon, MA earlier this month. The answer is, 350 to 570 is the number of caterpillars a pair of chickadees needs every day to nuture their chicks from hatching to fledging. That’s just one pair of one kind of bird! Ellen inspired us to think and learn about every plant and practice in our gardens, and whether and how each helps or harms the natural systems that support all living things.

Ellen, who manages the church’s extensive gardens, showed examples of native plants at the church’s gardens and at her own home through the seasons, and how they support or harm our native pollinators, wildlife and local ecosystem at large. She even talked about plants she introduced to her gardens on purpose, only to find out years later that they were actually exotic invasive look-alikes of native plants. For example, she thought she was planting yellow marsh marigolds (Caltha palustris), but they turned out to be fig buttercups (Ranunculus ficaria, or, Ficaria verna), which are on the MA list of plants that are prohibited from sale.

After about three years they had spread like a spring carpet of yellow, in part because they aggressively reproduce by three different mechanisms. Once she realized her error, Ellen  took responsibility and removed them by hand, an intensive but organic gardening practice. It took three seasons to bring their numbers to a manageable level.

Ellen also reminder us that one of the Unitarian Universalist Church’s guiding principles is respect for the interdependent web of all existence of which we are a part. She urged us to think carefully and learn about the impact of each of our plantings, as every plant in our landscapes matters, and your landscape supports, or doesn’t, those chickadees who need all those caterpillars every day to raise their young.

WANTED: DEAD NOT ALIVE Invasive Plants Exhibit Wins Educational Excellence Award

Invasive plants exhibit at Sharon Garden Club September Garden Medley

WANTED: DEAD NOT ALIVE received an Educational Excellence award at the Sharon Garden Club’s September Garden Medley on September 9, 2017. The exhibit featured potted exotic invasive plants and illustrated some of the environmental damage they cause. Left to right are Carol Lundeen of Easton and Brenda Minihan and Ellen Schoenfeld-Beeks of Sharon. The trio played roles as invasive plant sheriffs, engaging visitors in conversation and offering invasive plant checklists, images, and ideas for native plant alternatives. Photo by Carol Lundeen.

WANTED: DEAD NOT ALIVE received an Educational Excellence award at the Sharon Garden Club’s September Garden Medley on September 9, 2017. The exhibit featured potted exotic invasive plants and illustrated some of the environmental damage that invasives cause. Carol Lundeen of Easton and Brenda Minihan and Ellen Schoenfeld-Beeks of Sharon played roles as invasive plant sheriffs, engaging visitors in conversation and offering invasive plant checklists, images, and ideas for native plant alternatives.

Exotic invasive plants have no natural predators and diseases that would naturally control their growth. Some invasive plants have escaped from our home gardens and public plantings into natural areas and cause profound environmental and economic damage. Massachusetts has developed a list of problematic plants. Some are even illegal to sell, including Norway maple, Japanese maple, burning bush, all hollow-stemmed honeysuckles, garlic mustard, oriental bittersweet, and Japanese knotweed.

The exhibit also included a “Talking Tree,” a young pin oak tree that posed the question, “When I turn one hundred years old, what do you hope I will say?” Visitors then wrote their answers on a card and tied their card to the tree with yarn. The tree will be planted at the Unitarian Universalist Church in the center of Sharon.

The sheriffs urge folks to learn about the species considered invasive in the area, generate a list of those on your property or in your town, create a plan for eliminating them, and execute your plan. Contact the Sharon Garden Club or Carol Lundeen for further information.

Is Bitter-cress a Weed to Worry About in Early Spring?

 

Bittercress blooming in early April in Sharon, MA

Hairy bitter-cress, Cardamine hirsuta, in bloom now in Sharon, MA.

 

Hairy bitter-cress is very pretty up close, but is it a weed? If you could ask your MA soil if it’s a weed, the soil would say, “Yes, it’s a weed.” If you ask the whole ecosystem of your MA yard, the system  would agree that it’s a weed.

This is hairy bitter-cress, a native to Asia, that as an exotic invasive plant has an unfair advantage over our native plants, blooming and casting its seed well before most of our natives have even formed flower buds. So, is it a weed to you? If so, better destroy those pretty flowers before they turn to seeds. If you need more info about how, please let me know!r-cress, Cardamine hirsuta, in bloom now in Sharon, MA.
