White Azaleas are one of those amazing plants that offer interest four seasons out of the year. In the summer and fall they sport their gorgeous green leaves, and in the winter, some evergreen varieties even retain their leaves. In the spring, of course, they fill your garden with their stunning blooms!
In order to ensure that you get the most out of your white azaleas, it is important that you choose the perfect location for them. These plants can tolerate both sun and shade, however neither one of them should be excessive. They will also have two different effects to your plants. If placed in the sun, your bush will produce brighter and more frequent blooms but the blooms won't last as long. They will also be very compact and the bright flowers they do produce will be quickly bleached by the unforgiving rays of the sun. If planted in a fair amount of shade, they flourish but will have few blooms. It depends what you want from your azaleas, but it is generally recommended that they be planted in the shade.
The site that you select should also offer some form of wind protection. White azaleas are sensitive to windy conditions, and too much of it can cause damage. Therefore, planting them next to evergreen shrubs or trees such as pine will offer them some slight protection. The white azaleas will also contrast with their emerald green foliage, making for a nice combination.
Soil quality and it preparation is also important for the success of your plants. You should never plant in an area with inadequate drainage. White azaleas will never flourish in this environment, regardless of what you try and do to coax life out of them. If you are unsure of your soil's drainage, there are two methods you can try. If you wait until a heavy rainstorm, you will notice whether or not water is pooling at the surface, though this sometimes isn't enough of an indicator. A more exact way to test is to dig a hole 6 inches deep and then fill to the top with water. You want the water to drain from the hole in less than four hours. If it doesn't and you still want to plant your azaleas there, you can raise the bed a foot from ground level. This should fix the issue.
Preferred soils are ones where azalea's delicate roots can penetrate with ease, therefore, it is recommended that you plant in fertile soil. If your soil quality is poor, you can amend it with 3 to 4 inches of compost. It must also be slightly acidic, with a pH level between 5.0 and 5.5. If your soil is not acidic, you will have to amend it with fertilizers that will raise its acidity.
Plant location and soil quality are two of the most important factors when planting anything, especially plants as delicate as white azaleas. They will only require watering if your area doesn't receive at least an inch or two of rain per week, though you will need to water more than this until the azaleas are established in their new home.
