Community Gardens – Planting Outside the Box! (July 15 and 18, 2017)
Community gardens are special places and through partnerships and imagination they can meet many needs of a neighborhood. First they are places for families to grow food which can be achieved through many methods including raised beds, in ground plantings, forest gardens, and orchards. All of these methods are in practice at the Rooting for Families Community Garden at Manchester Community College, which serves nearly 40 Manchester area families saving them at least $500 each on their grocery bills.
The design of the garden also builds community and gives inner-city families a place to reconnect to nature. It includes an outdoor classroom, a community space for larger gatherings, smaller picnic areas for families to gather, and an orchard spiral that includes herbs, small fruits, pollinator plants, and a bench for reflection. Most recently a natural playscape adds more activities for families to do outside the garden.
If you are thinking about beginning a community garden or if you are already part of one, think outside the traditional garden bed and see how other needs of your community can be met. For a future community garden space in Manchester or to help out, contact The Way Home at (603) 627-3491.
Grubs in the Lawn, Oh My! (July 8 and 11, 2017)
How do I know if I have grubs in my lawn? Why does my lawn have grubs but not my neighbor? Home lawn areas in New Hampshire often are subject to severe and extensive injury by the larval stages (grubs) of various species of scarab beetles. Japanese beetles and European chafer grubs are the predominant damaging white grub species associated with home lawns. Several other white grub species including Asiatic garden beetle, May and June beetles, and Oriental beetle are occasionally observed in home lawns and may cause significant damage. Tune in and learn what to look for and how to manage them.

Protecting Trees and Shrubs from Lawn Mowers and String Trimmers (July 1 and 4, 2017)
Prevent mechanical damage from mowers and trimmers by incorporating trees and shrubs into larger planting beds that are separated from lawn areas. In nature trees and shrubs aren't found surrounded by single plantings of lawn, but typically grow with several other plants. Creating beds, separated from lawn areas, around your trees and shrubs and under planted with lower shrubs, perennials, and groundcovers, provides many benefits. For example planting beds keep the mowers and trimmers away from vulnerable bark. Mowing and trimming grass at the base of even older woody plants causes damage and can lead to the plant's demise as the growing tissue or cambium layer is just under the bark. With plants in a planting bed it is much easier to mow around the edge of the bed and the plants are protected.
Once you have a plants in a bed you can cover any exposed soil with a mulch. Making sure the mulch is no more than 3 inches deep and an inch or two away from the base of the plant. No volcano mulching please as it keeps too much moisture up against the bark and encourages the roots to grow up rather than out and down as the plant searches for air and water.
