Helping the kids with their gardens a few years ago. (I'm laughing because I've just suggested tot spot chairs for all the kids and here I have only one out and I'm using it, ha.)
Ok, here's a photo of them in their chairs. (They help keep everyone happy.) Taking a break and soaking in their hard work.
This is the chair. I bought six of these from $5-$15 on Craigslist and Kijiji.ca. They fold up and come with a carrying bag and are so well made. They hold adults, too, and are comfortable. We use them in our backyard for extra seating for kids, at the beach, parades, etc
OK, step 1. Dig a hole. Yup, pretty simple.
Step 2. Pour some water in the hole so the plant roots aren't sitting in dry soil.
Step 3. Have them turn their plant upside down, holding container with one hand, the other hand holding the base where the plant meets the soil.
Step 4. You want to loosen the pot-bound roots. Gently pull soil and roots apart with hands.
Step 5. Place plant into hole and move the dirt back into the hole and around the plant.
Step 6. Press down around the base of the plant to ensure it is securely stable and set in the dirt at ground level.
Step 7. Water! (In any position that works.) Get them watering in the mornings before the sun hits the garden for best water absorption.
