The most popular flowers that go best in hanging pots are also some of the easiest to grow. Colorful flowers trailing over the sides of the pots are not difficult to achieve. One problem growers face is that hanging pots dry out very quickly. Water often runs directly through a hanging pot, dripping out the bottom. Watering and fertilizing must be done diligently to maintain hanging pots throughout the growing season.
Wave petunias spill over the sides of hanging pots with cascades of flowers. One of these magnificent plants will fill a very large hanging pot and create a globe of colorful flowers. Feed Wave petunias weekly with a soluble fertilizer, or incorporate a timed release fertilizer in the planting soil. Provide plenty of water. Wave petunias never need to be pinched back. Instead, allow the trailing branches to cascade and bloom freely.
Fuchsias make ideal plants for hanging pots. Fuchsias are heavy feeders. Timed release fertilizer mixed into the soil, or a weekly feeding regimen, will encourage more flowers. Keep the spent flowers and seed pods picked off the plant, and it will continue to bloom until late summer. Propagate new plants from cuttings in late summer, and root them in small pots. The rooted plants should be moved into larger pots in a greenhouse or indoors in autumn. Begin pinching off the growing tips at this time, and continue pinching them all winter to promote well branched, bushy plants by spring.
The types of begonias used in hanging pots are tuberous begonias. They are grown from tubers, which are not cold hardy and must be brought indoors over the winter. Hanging pot begonias have trailing stem types that cascade over the sides of the pot. This type of begonia produces flowers 3 inches or more across, and they may be any shade of red, magenta, pink, orange or yellow.
Ivy geraniums trail over the edges of a hanging pot, with a fine display of shiny green leaves and bright flowers. Ivy geranium blossoms may be white, red or shades of pink. Some varieties feature variegated foliage. Ivy geraniums need regular fertilizing once every two weeks throughout the summer. Deadhead the plants to maintain flower production all season. Move your ivy geranium where it will not freeze in the winter, and it will go dormant; it will begin growing again the following spring.
