To ensure that you have flowers throughout the winter, use hardy perennials such as salvia and bee balm.
If you want to conveniently bring flowers inside during cold snaps, you should use containers.
Spread mulch over plants to prevent frost damage to the roots and to help maintain moisture.
When flowers are withering or dead, prune them on a regular basis to stimulate new growth.
Fertilize the plants sparingly so that they can maintain blossoms without being overpowered.
To create the appearance of spontaneous growth, place flowers in bright areas, even within the house.
In times when blooms are sparse, it is important to provide fresh sugar water as a backup source of sustenance.
