Spring flowering bulbs need fall or winter planting. If you can dig the soil, you can plant cold hardy bulb such as tulips, daffodils, crocuses, hyacinths and some lilies.
Flowers like Tulip, daffodil, crocus and hyacinth do very well in full sun. Remember it is also important to pay attention to the drainage of the soil. If the soil does not have the proper drainage, the roots will drown. Bulbs like fertilizer and good soil.
Plant the bulbs at least 2 to 3 times as deep as the bulb is long. If you have sandy soil, they can be planted a little shallower.
The pointed side of the bulb faces up and the root plate faces down. Press the bulbs into the soil and then cover with soil. Tamp the soil down gently and water.
If you have rodents plague your yard, beware that they will dig up and eat most bulbs. They seem to really enjoy tulips, but usually ignore daffodils. To keep tulips coming back year after year, you may have to put each one in a little cage underground to keep the critters away.
