“Gardening for Health and Nutrition” is an ongoing program at the Essex County Environmental Center aimed at children ages 7 to 12. Participants learn the best ways to garden for plant growth, production and food quality, as well as gardening methods that keep the soil and land healthy. The next class, which is Wednesday, July 21 at 3:45 p.m., is part of a six-month series which provides a complete health and nutrition program for young gardeners. Your child doesn’t have to attend every class, but advance registration and payment is required for the ones you do go to. The cost is $8 per child per session, which includes a $2 materials fee.
