The Boston Natural Areas Network, which boasts a 10,000-gardener membership, is currently working on expanding its operations in Dorchester with new programming and community gardens. Upcoming programs include a gardening workshop on June 18 at City Native horticulture center in Mattapan and a July 9 garden “workout” at Nightingale Community Garden off Park St. in Dorchester.

Both programs are meant to technically and physically train what BNAN organizer Grantley Payne expects to be an influx in Dorchester gardeners. “We’re working on acquiring more plots this year, so we’re expecting more gardeners who will tend those plots,” said Payne, who oversees the BNAN’s Dorchester operations.

Of the BNAN’s 10,000 gardeners, about 1,200 live in Dorchester, according to Payne’s estimates. The network currently owns 250 plots in Dorchester, but plans to increase that number by almost 50 percent by the end of this month with the completion of a Nightingale Community Garden redevelopment project. Payne’s long-term goal for Dorchester is to have 500 community gardens in operation.

The gardens, many of which are small plots formerly owned privately or by the city, cost about $20 each year to maintain – water being the only cost – and are each tended by one or two community members.

Those interested in learning more about succession and companion planting, vertical growing, mulching, and water conservation can attend the June 18 event, “The Well Tended Vegetable Garden,” hosted by BNAN staff member Erika Rumbley. Payne will be hosting his July 9 workout, titled “Are You Garden Fit?” that will feature yoga, strength training, and Zumba to get participants fit for gardening season.
