Possibilities Shovel, glass, ax, spoon, rototiller, rake, dandelion picker. Do it myself or ask the kids to do it. Viability I don't have much time, and the kids only want to plant. Glass will break. Spoon, axe, and dandelion picker take too long.
Combinations Use shovel, then rototiller.
Use rototiller, then rake. Select Rototiller and rake. Apply Took about 45 minutes because the rototiller got caught on rootballs. Talked to kids about planting. Kids got seeds while I worked.
