The Johanna Azalea is an evergreen shrub that produces masses of red ruffled blooms. This shrub looks great all year around. Spring and summer provide crimson colored flowers with dark green foliage while autumn and winter bring warm, red foliage.

The Johanna Azalea is a hardy shrub that is densely branched. Masses of intensely pigmented blooms are produced in mid spring and provide long lasting color. Foliage is dark and glossy in the summer, but soon turns red in the fall and winter. This shrub stays small and compact only reaching a height and width of 4 feet. It is virtually maintenance free!

The Johanna Azalea is great for many uses. It can be used as a foundation planting, border, or hedge. It adds a great pop of color to any shaded or naturally wooded area. Use it in a mass planting or even as a lone specimen. This Azalea is great for a container.

The Johanna Azalea prefers partial sun to partial shade and moist, highly acidic soil. When choosing and area for you azalea, be sure to keep this in mind. Dig a hole twice as wide as the pot that your shrub has arrived in. Remove the shrub from the pot and gently probe your fingers in the bottom of the root ball to break up the dirt.

Place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil. Backfill the hole while gently tamping the soil to remove any air pockets. Water thoroughly. Be sure to put mulch around the base of the shrub, to inhibit the growth of weeds and protects the roots from cold weather.

This shrub does not require regular pruning, however if you feel the need to do so, trim only after flowers have started to fade away. Apply our slow release fertilizer in the spring to ensure the best flowering results.

Johanna Azalea Care

When planting your Azalea be sure you have the right location and conditions for your new plants to thrive.

Planting time: Spring and Fall are ideal times to plant Azaleas. However, if you avoid freezing and extremely hot temperatures you can plant any time of the year.

Sun: Full sun tends to burn most Azaleas especially in warmer climates so look for a site that provides a balanced mix of shade and sun.

Soil: Be sure your soil is well-drained and acidic. If you have alkaline soil, be sure to amend your soil. To acidify your soil amend with compost, elemental sulfur, or use fertilizers specific for acid loving plants. Mulching with pine straw or pine bark will help over time as they begin to break down, but are not an immediate solution. To improve drainage in something like a heavy clay soil, add compost and be sure to loosen up the soil well before planting.

Fertilizer: Choose a fertilizer for acid loving plants. Fertilize in late winter or early spring to give the upcoming blooms a boost.

Pruning: You don’t need to prune azaleas, but pruning after they are done blooming can help encourage a bushier growth and renew an older plant.

Landscape ideas

The Johanna Azalea adds vibrant color to the southern landscape and beyond. Azaleas are excellent for borders and mass plantings. This evergreen shrub jazzes up gardens and mixed beds. At 3 to 4 feet tall and 4 to 5 wide at maturity this stunning azalea can even be used in foundation plantings.  For borders or hedges plant about 4 feet apart on center. Otherwise, plant about 6 feet apart to give your plants space in-between.
