Bulb species usually lose their upper parts during adverse conditions such as summer drought and heat or winter cold. The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle.

The yellowing leaves will continue to absorb sunlight, feeding the bulbs for the following year's flowers. Now, you can dig up the bulbs, let them dry and store them to plant in the fall. This ...
Like many bulb plants from temperate regions, a period of exposure to cold is necessary before spring growth can begin. This protects the plant from growth during winter when intense cold may damage it. Warmer spring temperatures then initiate growth from the bulb. O. umbellatum spreads aggressively in clumps by means of these offsets. [16] [30]
Flowering plant bulbs are planted beneath the surface of the earth. The bulbs need some exposure to cold temperatures for 12 to 14 weeks in order to bloom. [1] Flower bulbs are generally planted in the fall in colder climates. The bulbs go dormant in the winter but they continue to absorb water and nutrients from the soil and they develop roots ...

The bulbs of Nerine species need a minimum of two years growth and development in order to produce their first flowers. The largest bulbs can give rise to two stems or more if they have been grown under suitable conditions. They are used as cut flowers as they can survive up to 14 days in a vase with water without showing any staining. [12]
Prune panicle hydrangeas in late winter or early spring before new growth emerges. Pruning is not necessary but can be used to increase blooms, shape plants, or control plant size.
