Bi-Mart was having a great sale on bulbs at the end of December, right before Christmas, and I bought a bunch. Then procrastinated - let the bulbs sit til about 12/31. Then bulb planting frenzy. I used containers and in the ground.
Here is a make shift container - garbage bag over a plastic milk crate, filled with compost and potting soil; then and planted with daffodils and tulips. This compost was home made, c2010-11. Just now using it.
I covered the bulbs with straw during the dead of winter.
Even though I wait til the last minute, the bulbs seems to do ok and come through!
