How do I prune Delaware Valley White Azalea Shrubs?
Azalea Delaware Valley Shrubs, commonly known as Deciduous Azalea, are closely related to our native azaleas. This deciduous shrub is known for its brilliant summer display of cheery pink blooms early to mid-summer. The flowers bloom during the previous growing season, so you must wait to prune until blooms expire to avoid cutting off the developing flower buds. Many times, Azaleas that have not been pruned in a few years will develop dead or degenerative twigs. Removing the dead and dying limbs will minimize the possibility of diseases such as “dieback” and allow the plant to re-concentrate its energies and produce flowers. Another reason for pruning Azalea Shrubs is that it may outgrow its intended size in the landscape and must be pruned to re-define its purpose. Pruning should always be associated with re-invigorating a plant by allowing it to focus its energies on producing more vigorous branches, foliage, and flowers. It is also vital to understand the specific growing characteristic of specific Azaleas when pruning that particular plant. During the second season following the severe pruning, the Azalea Delaware Valley Shrubs should resume normal bud setting and healthier blooms because of the increased vigor in the plant.
How do I mulch Delaware Valley White Azalea Shrubs?
We highly recommend that you mulch your Azalea Delaware Valley Shrubs with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any mulch will do, but cypress or hardwood mulch will be of a higher quality. They will also provide better nutrition overall as they break down. Mulching helps keep weeds away that compete with your new investment for water and nutrients. A 2 to 3-inch layer of mulch is sufficient but remember to take care not to cover any part of the stem with mulch. It's better to leave a one-inch gap of space between the mulch and the stem or trunk of the plant.
How do I fertilize Delaware Valley White Azalea Shrubs?
Azalea Shrubs grow best if fertilized lightly in the spring once frost has passed with a well-balanced, extended-release fertilizer such as Espoma Holly-tone. Fertilize Azalea Delaware Valley again 6 to 8 weeks later to encourage extra flowers or faster growth of young shrubs. Either chemical fertilizers or organic matter can be used successfully with Azalea Shrubs. If chemical fertilizers are used on your Azalea Shrubs, applying a slow-release, balanced fertilizer once a year is probably the simplest solution. However, slow-release is certainly not the only way to fertilizer Azaleas such as Azalea Delaware Valley. A less expensive fast-release fertilizer such as a 10-10-10 will work just as well if applied twice during the early spring and very early summer. Do not fertilize Azalea Shrubs after August.
How do I water Delaware Valley White Azalea Shrubs?
After backfilling and lightly compacting the 50/50 mix of existing soil and compost, give the Azalea Delaware Valley Shrubs a deep watering. Do not rush this process. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example, when watering a one-gallon pot, do not stop until you count to 5. For a three-gallon container, you would count to 15 before stopping watering. For the first week, check the plant daily and then every other day. Be sure to water using the counting method for the first few weeks.
