There are a few fall blooming bulbs available for use in the landscape. Design Considerations Mass Planting - Keep in mind that planting bulbs of one variety or color in mass will have greater visual impact. This will provide uniform color and texture that is pleasing to the eye. Bulbs will be easier to care for since they will have the same cultural requirements and the foliage will mature at the same time. Never plant bulbs in a single straight row or in a single circle around a tree or bush, except in very formal gardens.
Bulbs look better when they are planted in mass.
Plants don't grow in a single straight line in nature. They tend to grow in irregular masses. Grouping Bulbs - With the major spring flowering bulbs such as tulips or daffodils, plant at least twelve bulbs of one variety in a grouping. The more bulbs planted of one variety and color, the greater the impact. The smaller spring bulbs should be planted in groups of 50 bulbs or more to have impact.
