Many people plant flower bulbs in neat garden plots and around the bases of trees or bushes. This gives a formal, orderly appearance to the yard. Others like to make a more natural look by planting flower bulbs right in their lawn. Before the first lawn mowing of the season, you will have a bright and colorful lawn filled with flowers. Over time, these bulbs will grow multiply, increasing the area of your yard covered with flowers. This is called naturalizing, and some bulb plants are better at it than others.
