Bags of bulbs, tubers, and rhizomes arrive in moist peat moss packing material or in paper bags.
- If packed in peat moss, keep moist and wrapped roots loosely to prevent them from drying out until you plant them. In general, before planting, bulbs should be stored where they will not freeze, at around 45°F. We recommend a garage or basement.
- Healthy bulbs are firm without soft or mushy spots. Some surface mold is normal and will not affect growth.
- You may see small buds at the crown of tubers (where the roots meet the top growth). Bulbs may sprout in the bag if temperatures are warm - just be careful not to damage the sprout when planting.
About Bulbs, Tubers & Rhizomes
Some plants survive winter by storing their energy in underground bulb, tuber, or rhizome structures. You'll often see these terms used interchangeably, and we typically refer to them as bulbs on our site.
- Tulips, Daffodils, Alliums, and Hyacinth are examples of fall-planted bulbs. Gladiolus and Elephant Ears are examples of spring-planted bulbs.
- Bearded Irises are popular flowers that grow from rhizomes.
- Dahlias are popular flowers that grow from tubers.
The plants do not have top growth, but these underground structures hold all of the energy and information a plant needs to grow vigorously into a full-size plant once they're in the ground. Typically, most flower bulbs and tubers grow into their full mature size in just one growing season.
Like bareroot plants, these are dug after they go dormant in fall. The soil is then washed from the bulb, tuber, or rhizomes, and they're packed in moist wood shavings, shredded paper, or peat moss.
