I started my granddaughter with Zinnias when she was 3. She now helps with the other flowers, herbs, and vegetables. She kills bugs, weeds a little, picks veggies, plants most of our seeds, helps with watering, she can't seem to get enough. We are trying milk jug sowing...we have 30 jugs with a little of this and a little of that lol. Just her and I experimenting here in NNY zone 4a. She'll be 7 at the end of the summer. What a great time we are having!
