- Use more bulbs than you think you need – this is not an attempt to increase your purchase, but a true landscapers’ tip. The best visual effect comes from a grouping of bulbs.
- The bulbs you purchase are in a dormant state – if you leave them unplanted they can sprout during a period of warmth. To prevent this, store them at cool temperatures (65-70°) until planting. (If you use a refrigerator take care to keep bulbs separate from fruit – fruit emits a gas that can destroy bulbs.)
- Check the plant height on the package – plant low-growing bulbs in front of taller ones. Think about the color when selecting your bulbs.
- Contrasting colors create bold displays (i.e., pink and purple, or red and yellow) whereas variants of a similar hue will result in refined, soothing plantings. The liberal use of white is another trick often used by professionals to add brightness and visually tie together the garden.
- For zones 1-4 or in any particularly cold climate, gardeners should consider covering their planting with a layer of leaves or a protective layer of 4″ of mulch.
- Southern gardeners in zones 8-10 may need to trick their bulbs or “precool” them prior to planting. Bulbs need a cold period of about 3-4 months in order to develop properly. The bulbs should be stored at about 40-45° for a period to 8-10 weeks, depending upon the upcoming cold period.
