Azaleas Are Colorful Garden Plants

Many varieties grown in southern gardens are not adapted in certain conditions. Given proper conditions they can become outstanding plants in the garden. Some varieties of the deciduous species are hardier. There are better adapted to colder areas. Most popular of the evergreen azaleas are the Kurume hybrids. Their masses of flowers cover the entire, plant, from about mid to late April. Some Kurume azalea varieties endure temperatures around zero, but may be injured unless protected.

Gable hybrids are another relatively hardy group of evergreen azaleas. They were bred especially for hardiness. Some suitable varieties are Elizabeth Gable, Herbert, Boudoir, and Rosebud. Kaempferi hybrid azaleas are somewhat evergreen but may become deciduous. They flower a bit later than most of the above types. Suitable Kaempferi varieties include Fedora, Cleopatra, Thais, Atlanta, and Lilac Time.

Deciduous azaleas, generally more hardy than evergreen azaleas, include the Mollis, Ghent, and Exbury hybrids. Many have survived temperatures as low as 15 degrees below zero. Among the many different types and varieties, a complete range of colors may be had with the exception of blue. Deciduous varieties do not differ in cold hardiness as much as in evergreen types.

Azaleas can be planted when in full bloom. With so many types and varieties to choose from, the most satisfaction often comes from plants purchase in bloom. Azaleas planted well and in healthy condition will tolerate winters better than weak plants. In cold areas, select a location protected from wind in winter and shaded after about 1 p. m. in the summer. North or east sides of buildings often provide these conditions. Azaleas may be grown beneath pine trees. However, root competition often makes summer watering necessary.

Azaleas require acid soil and good soil preparation. Large planting holes should be dug or entire planting beds worked up. Remove the soil and add liberal amounts of peat moss or leaf mold. In heavy clay soils as much as 50 per cent by volume organic matter should be added to the soil. Set plants so they are no deeper than they have been growing in the nursery. Make sure plants are placed high enough so stems will not be covered as the soil settles.

After planting, mulch with leaf mold, sawdust, wood chips, or similar available organic materials. Do not cover the stems with these materials during the summer. However, in late fall, they may be pulled up around the plant to help give winter protection.
