I have planted bulbs in early spring but I needed to trick the bulbs by placing the bulbs in a brown bag then I added some peat moss and a few drops of water. In addition, I placed the bag in the crisper section of my refrigerator. I left the bulbs in the refrigerator for 6 to 8 weeks. I then took the bulbs out and planted them in containers. The tulips and daffodils grew, however the blooms were small and the foliage was not healthy. I think a force growing such as this is hard on the bulb. It is better to plant your spring bulbs in the fall and use markers so in spring you will know where all of your spring flowers are. Overall, spring bulbs need a nice cozy sleep throughout a cold winter, and when they awake in spring and start to bloom, they will be healthy and beautiful.
