The widest age range on this list — 2 to 18 — through a Learning Garden ladder, plus family drop-in volunteering and Saturday Crop Mobs.

Waltham Fields is the answer when a younger sibling wants to come too. Little Sprouts takes children from age 2 with a caregiver; Garden and Farm Explorers covers ages 5–13 after school; and Garden Corps runs for 13–18-year-olds and counts toward school service hours — useful when the hours are a graduation requirement rather than a nice idea.
For a one-off, there is family drop-in volunteering and the Saturday Crop Mobs. The supervision rule is clear and worth reading before you arrive: 15 and under must have a parent volunteering with them, and 16–17-year-olds need signed permission.
