How deep are the roots of an azalea?
Consequently, how do you kill azalea roots?
You can kill an azalea slowly by over-fertilization. The plant is especially susceptible to excess amounts of sulfur – it tolerates only a pound of sulfur per 100 square feet of planting soil. Apply excess elemental sulfur to kill the plant; once it is dead, you can easily pull it up by its trunk, root system and all.
Additionally, how deep are the roots on a rhododendron? Unlike deep-rooting shrubs such as yews, rhododendrons' and azaleas' roots run relatively close to the surface, usually within the top 12 inches of soil. They also have a vertical root structure from the center of the shrub which plunges the same depth or deeper, but which is fairly easy to free.
In this regard, are azaleas hard to dig up?
Newly planted azaleas (1 to 5 years old) should be easy to dig, while established plants will be more difficult. Dig as big a root ball as possible. A good rule of thumb is that the root ball should be half the diameter of your azalea.
How do you dig up old azaleas?
Dig a trench 12 inches out from the edge of the shrub, and about 12 inches deep, moving in a complete circle around the plant. This will help you cut the roots and give you leverage for removal. Push the shovel under the plant's roots toward the center of the circle, loosening the soil and creating a cone.
