This means that you would dig a small hole with a tiny gardening tool and carefully place and cover every single bulb one at a time. Not an exciting task. Particularly, when dealing with hard clay soil (depending on the bulb, heavy clay soil may require amendment).
I began to think: Since the objective is to get the bulb in the ground at a particular depth and cover it fully with soil, why not plant just plant them in groups?
Here is what I did:
1. I dug a shallow hole to the depth of the bulb’s requirements (mine were 5 inches). I hug the hole in the shape and width of the general area that I would like to plant my bulbs (I planted them in areas of approximately 2 ft x 1 ft).
2. Place into the hole where I’d like for the flowers to grow and bloom.
3. Fill the hole with the soil that I removed; carefully covering the bulbs completely.
4. Mulch over the planting area to discourage weeds from growing.
I loved this approach because it only takes a few minutes to dig the hole, get everything planted. It also made it easier for me to space and arrange the bulbs to my liking. I was able to plant nearly 100 bulbs in well under 40 minutes where as the other method would have taken several hours.
Tip: I recommend that you ditch the hand tools for the project in order to speed things up. Use a full-sized shovel to dig or, if you have hard or heavy clay soil, consider using a pitchfork. I find it a bit easier to get a pitchfork into the ground than a shovel with our clay soil. Also, to cover the bulbs. I found it faster and easier to use my hands. Try different things out. See what works best for you.
