Bring drill outside along with an extension cord.
Use a bulb drill bit/augur bit. We got this at our local garden center.
In early-mid Autumn, purchase bulbs. Place drill tip in ground where you want flowers to bloom.
With supervision if doing this with children, drill hole as far as augur blade goes (6-12").
Place bulb in hole. Make sure point faces up, root faces down. We're planting narcissi.
Fill hole with dirt. If you are going to fertilize, do so before filling hole.
Stamp on dirt.
Cover garden bed with mulch. Celebrate and wait for Spring!
