- Acidic houseplant fertilizer
- Peat-based potting soil
- Spray bottle
- Clay pot
Step #3: Keep the soil moist during the day. The soil should feel damp when you touch it, and not soaked completely. Do not drown the plants in water. If the flowers haven't bloomed yet, use a spray bottle filled with water to clean the leaves at least once a day.
You can use tap water to mist and water the plants. If you live in an area where you get alkaline water, add a tablespoon of vinegar to a gallon of water while watering, and not misting the plants.
Step #6: Once the plants grow in number, repot them during late summer or early fall. Most azaleas need repotting every 2 to 3 years in bigger clay pots. For repotting, add peat-based potting soil in the new clay pot and then transfer the plant along with the root system.
