Azaleas require certain soil conditions to thrive. May is a great time to check the soil and make sure it is optimal for good growth. These bushes need well-drained soil which is both liquid and acidic.
Azaleas thrive in soil with a pH between 4.5 and 6.0. It’s a good idea to do a soil test every year to make sure the soil is properly acidic. You can quickly test your soil with a simple one at home pH test, like this one from Ace Hardware.
Now is also a good time to amend your soil working in compost to improve its nutrition, texture and quality. Pine-based materials, such as organic pine bark compost, improve drainage and add acidity.
2. Prune your shrubs

It is better to prune the azaleas as their flowering cycle ends. With most of them azalea varietiesyou will enjoy the flowers and see them fade and fall by May. Prune them immediately after flowering.
Azaleas set their flower buds for next year during the summer before. If you delay pruning after flowering, you may cut off next year’s flowers. Pruning in May ensures that your shrub will produce healthy growth in addition to branches full of flowers next year.
To prune azaleas in May, first gather your tools. You will need hand pruners and a pruning saw, such as that of Fiskarsfor use on larger branches. Clean the cutting edges of both tools with rubbing alcohol before you start pruning to disinfect them.
The next step is to remove dead branches. These are easy to see at this point, as they will be the branches without living stems or leaves. If the branch is wider than your thumb, use the pruning saw instead of the pruners. Don’t forget to disinfect the tool again before any further pruning.
Once dead branches are gone, identify branches that are overgrown or out of balance with the shape of the bush. Make cuts just above a node. Continue cutting branches until your azalea is shaped to your liking.
3. Keep the water coming

Throughout the growing season – before, during and after flowering – azaleas need plenty of water. They require about 1 inch (2.5 cm) of water each week.
If it rains in your area, the rain may be enough. But if it doesn’t rain much where you live, then water your plants every week. Mulching around the plants helps retain moisture, so it can reduce the watering requirement a bit.
You can tell your shrub needs extra water if the azalea leaves are falling. Note that if you just planted your shrubs, they may need water every few days until their root systems are established.
4. Apply Fresh Mulch

Mulch it is magical when it comes to holding moisture in the soil and regulating soil temperature. Mulching is essential for azaleas in May.
These shrubs need moist soil and mulch helps ensure this, reducing the need for irrigation. A suitable mulch, eg this acidifying pine bark mulch from Walmartit also protects the soil from getting too hot or too cold and prevents weeds from growing. Excessive weeds steal nutrients and water from azaleas.
Mulching azaleas involves applying a layer of organic material, such as pine needles or shredded leaves, around the base of the plants to conserve moisture, regulate soil temperature, and suppress weeds. It is recommended to use about 2 to 3 inches (5-7.6 cm) of mulch, keeping it a few inches away from the stems to prevent common azalea diseases.
THE the best type of mulch to use for azaleas it is organic and acidic. They decompose in the soil over time, improving soil quality. Good choices include pine needles, dried shredded leaves, pine bark chips and organic compost. Use about 2 inches (5 cm) around the base of the bushes keeping it away from the trunks of the bushes.
5. Fertilize after flowering

It’s a good idea to fertilize your azaleas after you have pruned your bushes. Applying fertilizer at this time supports the future growth of your plants. It may also produce larger and brighter flowers the following spring.
You can find different fertilizers specifically designed for azaleas, such as this organic azalea feed from Espoma. These contain all the nutrients azaleas need for optimal health. Choose a granular, organic fertilizer that is balanced and slow-release to feed shrubs all summer long.
