Pruning tips


Indica azaleas are taller growing azaleas that put on an amazing blooming show for about a month, every spring. This plant sets the following years flowers in June so you will need to prune then immediately after they bloom but not after June. Other preferred varieties of Indica Azaleas are Judge Solomon, which is pink, Mrs. G. G. Gerbing, white and George L. Tabor which is light pink.Take a look at our 11 Shade Loving Shrubs.


It is not difficult to keep our landscape plants pest free. Proper plant selection is the first step for keeping a healthy landscape. Select plants that are less prone insects and plant plants that require sun in a nice sunny area. Keep islands and flower beds with a fresh thick layer of mulch to prevent competing weeds and to supply plants with ample water. Maintain and trim bushes regularly to give plants growing room and good air circulation to prevent diseases that attract unwanted insects.

Azaleas are not strangers to the occasional insect. In the southeast united States Azaleas are most likely to get Lace Bugs that will discolor the leaves but seldom kill the plant.

Because lace bugs hang out on the bottom of the leaves you will need to coat the tops and bottoms of the leaves with Bayer Tree and Shrub Systemic Insecticide with imidacloprid or Insecticidal Soap. There are many other pests that like to feed on azaleas. Scale, whiteflies and leafminers are commonly found on azaleas as well. 


STEP 1: Digging the hole

  • Find a location that has suitable sun exposure for your particular type of plant.
  • Dig your hole an inch or two shallower than the rootball of the plant.
  • Dig the hole twice the diameter of the rootball.
  • Scuff up the sides of the hole with a shovel to help roots break through the native soil.

STEP 2: Putting plant in hole

  • When removing the plant from the pot, check to see if the roots were circling the pot.
  • If the plant is rootbound, gently break up the roots with your hands until loosened up.
  • Set plant level, in the center of the hole.
  • Make sure the top of the rootball is just above soil level.

STEP 3: Amending the soil and filling in the hole

  • Amend the soil with proper amendments for your soil type.
  • Incorporate 50% native soil with 50% amendment soils like garden soil, composted manure or soil conditioner.
  • Make sure dirt clods are broken up or removed from hole along with rocks.
  • Fill the hole with soils to the soil level and pack down. Do not cover top of rootball with dirt.
  • Water in thoroughly to remove air pockets.

STEP 4: Mulching and fertilizing

  • Cover the planting site with at least 2 inches of the mulch of your choice (pinestraw, cupress mulch,etc.)
  • High Phosphorus root stimulator fertilizers like Quick Start from Miracle Gro are great to use at time of planting.
