How to Grow Azaleas Near Brick


Acidic soil, shade and moist soil provide the best growing conditions for azaleas, ornamental shrubs in the rhododendron family. Often, homeowners find azaleas near brick foundations of their homes. Azaleas provide landscape appeal and help hide foundations. Learning how to grow azaleas near brick prevents structural property damage and increases shrub survival rate.

Step 1

Prune azaleas near brick with sterile pruning shears during regularly scheduled pruning care times during the spring and just before shrub dormancy. Spray the pruning shears with disinfectant spray and allow air drying between cuts. Additionally, prune the section of the shrub that is closest to the brick, even though this may reduce bloom yield. Frequent pruning prevents moisture from collecting on the brick that causes mold and mildew growth.

Step 2

Dig a 2-inch-wide by 6-inch-deep trench between the azalea shrub and the nearby brick. The trench can be located as close as 6 inches to the shrub without causing plant damage for new or established shrubs. Fill the trench completely with quick cement and add the appropriate amount of water according to the bag instructions. Cover the cement at the soil line with dirt to camouflage. The trench prevents azalea roots from growing into the brick, which could cause structural damage.

Step 3

Sever the roots near the brick to prevent structural damage. Cut the roots by inserting a sharp spade into the ground near the brick. Water to reduce shrub shock to the azalea afterward.

Step 4

Water azaleas weekly with 2 inches of water. Provide 4 inches of weekly water for shrubs in sunny areas, to compensate for soil moisture evaporation. Some types of brick reflect heat onto the soil and the shrubs. Avoid over-watering by cutting watering volume in half if the growing area receives regular rainfall or is located primarily in the shade.

Step 5

Fertilize azaleas monthly during the growing period with a liquid fertilizer specifically formulated for azaleas. Root systems near bricks receive fewer nutrients. The shrub requires regular fertilization for the highest bloom yield.

Tips and Warnings

  • Avoid root burn and only apply liquid azalea fertilizer to wet soil.
