How to Care for Azalea Johanna
Be sure to read our planting instructions to ensure a healthy and happy plant for years to come!
How Often Should I Water My Johanna Azalea Shrub?
After backfilling and lightly compacting the 50/50 mix of existing soil and compost, give the Azalea Johanna Shrubs a deep watering. Do not rush this process. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example, when watering a one-gallon pot, do not stop until you count to 5. For a three-gallon container, you would count to 15 before stopping watering. For the first week, check the plant daily and then every other day. Be sure to water using the counting method for the first few weeks.
How Do I Plant My Johanna Azalea Shrubs?
We suggest when planting your newly purchased Azalea Shrubs that you dig a hole twice as wide as the root system but not deeper. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots of Azalea Shrubs to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted.
How Should I Mulch My Azalea Johanna Shrub?
We highly recommend that you mulch your Johanna Azalea Shrubs with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any mulch will do, but cypress or hardwood mulch will be of a higher quality. They will also provide better nutrition overall as they break down. Mulching helps keep weeds away that compete with your new investment for water and nutrients. A 2 to 3-inch layer of mulch is sufficient but remember to take care not to cover any part of the stem with mulch. It's better to leave a one-inch gap of space between the mulch and the stem or trunk of the plant.
How Do I Fertilize My Azalea Johanna Shrubs?
Azalea Shrubs grow best when fertilized lightly in the spring once frost has passed with a well-balanced, extended-release fertilizer such as Espoma Holly-tone. Fertilize Azalea Johanna again 6 to 8 weeks later to encourage extra flowers or faster growth of young shrubs. Either chemical fertilizers or organic matter can be used successfully with Azalea Shrubs. Since an organic method of applying manure and/or compost around the roots produces excellent results and improves the condition of the soil, this would be an excellent first line of attack. Organic additions to the soil can be combined with a shot of chemical fertilizer for maximum effect. If chemical fertilizers are used on your Azalea Johanna shrubs, applying a slow-release, balanced fertilizer once a year is probably the simplest solution.
