Yep, without any effort of your own, they will come back in greater numbers. Yes, by definition. But in practice, some bulbs, notably many tulips, are finicky and require optimal soil, water, and light conditions in order to thrive. Tulips are native to Central Asia and Southern Europe, but many cultivated tulip varieties sold in the US will not naturalize. Most American gardeners treat tulips more like annuals, as they tend to peter out after the first season.
Third, figure out the general size and shape preferably curved and asymmetrical of your natural plant colony; consider using a garden hose or rope to map out the area. Then, literally scatter your bulbs within the border of this space and dig holes where they land. Add compost as you plant the bulbs and water well.
The key, in fact, is to leave them alone. After flowering, the foliage on naturalized plantings should be allowed to die back on its own which can take as long as eight weeks. The wild daffodils such as Narcissus lobularis , N.

You wait for them. They come back as "friends. Spring-blooming bulb flowers — including daffodils, species tulips, grape hyacinths, crocus, scilla, and more — can be planted to naturalize in beds, ground covers, even the lawn where you can tuck the bulbs right under the grass.
Pace yourself. Each year treat yourself to something new or something more. Many spring-blooming bulbs will thrive in a wide variety of garden conditions. Some, including many tulip varieties and hyacinths, are best treated as annuals. Technically, naturalizing bulbs are those that accommodate themselves fully to their new sites, feeling so at home that they multiply naturally, on their own, increasing in numbers year after year. Why will some bulbs naturalize and others won't?
Actually, most bulbs are, by definition, perennials. But, in reality, not all bulbs will adapt to diverse growing conditions so readily. A lot depends on the particular type of bulb and the particular planting site. Soil, climate, water, and other conditions all play a part in determining which types of bulbs will be the best repeat performers in any given environment.

In garden beds, work organic matter such as compost, well-aged cow manure, or peat into the soil, mixing it in deep enough to provide drainage at root level. Consider the sunlight. Most bulb plants prefer full sun. For early and mid-season spring bloomers, most deciduous trees will not yet have leafed out.
