   Dividing Tuberous Begonias   

" I've been growing the same begonia bulbs for a number of years and they are getting rather large. I normally start them mid-March by sinking the bulbs about one-half their depth in peat moss. As of today, most of the bulbs have buds and a few have leafy stems about 2 inches high. Is it not a good time to split them? When is the ideal time to split them? Do the cut surfaces need to dry before storage, or in the present case, before setting them back in the peat moss? Or can I split them right as they are in the peat moss? If so, do the cut surfaces need to be dusted with anything to protect them from deterioration? " - Read the answer


Growing Hibiscus
Hibiscus are large shrubs or small trees that produce huge, colorful, trumpet-shaped flowers over a long season. They are generally divided into four groups: Hardy Hibiscus, Rose of Sharon, Tropical Hibiscus, and all the various species of Hibiscus.
Should you use Epsom Salt?
After working with home gardeners for more than 10 years, I know that they love to use home remedies on their plants. From setting out beer traps for slugs to hanging bars of soap to repel deer, if the household product seems to work, gardeners try it. That's why I was intrigued by the often-mentioned idea of using Epsom salts as a fertilizer.
Growing Spirea
Among the easiest flowering shrubs to grow, spireas are often used in foundation plantings, as hedges, and in perennial gardens. Most spireas bloom in late spring to midsummer. Flower colors include pink, red, yellow, and white, depending on the variety.
Growing Foxglove
Foxglove's low-growing foliage is topped by 2- to 5-foot-tall flower spikes, depending on the variety. Flower colors include pink, red, purple, white, and yellow. Foxgloves are biennials or short-lived perennials.
Growing Ranunculus
Brilliantly colored flowers are 'ranunculus' chief attraction, and they are indeed special. They most often come in multiple layers of delicate, crepe paper--thin petals, looking like an origami masterwork. Ranunculus (R. asiaticus) excel in southern and western gardens, and make terrific container plants everywhere. They also make long-lasting cut flowers.
Growing Hyacinth
Favored for their intense colors and heady fragrance, hyacinths are a staple of the spring garden along with daffodils and tulips. The plants' stately appearance makes them prized in formal bulb plantings. Flower colors include rich magenta and deep indigo as well as paler pinks, baby blues, yellows and white.
