Azalea Fertilizing in 7 Easy Steps

Azaleas are beautiful flowering shrubs that can add a splash of color to any garden. But to keep them looking their best, they need to be fertilized regularly. Here's a step-by-step guide on how to fertilize azaleas:

1. Choose the right fertilizer. Azaleas prefer a fertilizer that is acidic, with a pH of 4.5 to 5.5. You can find fertilizers specifically designed for azaleas at most garden centers.

2. Fertilize in the spring. The best time to fertilize azaleas is in the spring, just as they are starting to grow. This will give them the nutrients they need to produce flowers and foliage.

3. Apply the fertilizer evenly. When applying fertilizer, be sure to spread it evenly around the base of the plant. Avoid getting fertilizer on the leaves, as this can burn them.

4. Water the fertilizer in. After applying fertilizer, water the plant deeply. This will help the fertilizer dissolve and reach the roots of the plant.

5. Fertilize again in the summer. Azaleas can benefit from a second application of fertilizer in the summer. This will help them continue to produce flowers and foliage throughout the growing season.

6. Avoid over-fertilizing. Over-fertilizing can damage azaleas. If you are not sure how much fertilizer to apply, it is always best to err on the side of caution and apply less.

7. Test your soil. Every few years, it is a good idea to test your soil to make sure that it is still acidic. If the pH of your soil has risen above 5.5, you may need to add sulfur to lower it.
