Azaleas - Unhealthy

A check list of cures and cares for azaleas.

Azaleas are shallow rooted and require lots of water in a well-drained and aerated soil. If an illness results in the plant check these clues.

Poor growth, overall yellow and small foliage and a general unthriftiness describe too many of our azalea plants. A number of reasons can cause our plants to fit that description and not to grow and flower as we expected.

The more usual causes are:

• poor soil,
• planted too deeply
• improper fertilization and water
• soil born diseases
• insects.

Generally, if we meet the cultural requirements of our azaleas they will be attractive in foliage and in flower.

Check list…

If you have one or more ailing plants, run through this check list:

• azaleas grow best in partial shade
• a well drained, slightly acid soil
• careful attention is given to the depth of planting, mulching, watering and fertilization.
• Gardeners will have more success if they prepare a bed of azaleas rather than individual plantings.
• Deep spading or plowing is advisable.
• Also, the selected planting site should be sloped enough so that water does not accumulate
• When planting be sure that you do not set the plant any deeper than it grew in the nursery or container. If in doubt, set the plant slightly higher than the surrounding ground.
• Pull the prepared soil up and over the root ball until it is covered by one inch of soil.

Mulch

A good mulch of 3 inches of pine straw, hay, leaves or bark will help keep the soil from drying or from becoming excessively warm. A mulch is also very useful in reducing weed problems.

Remember azaleas are shallow rooted and will require a thorough watering once a week if soaking rains do not occur.
