How Much Water Do Azaleas Need?

Azaleas typically need 1 inch (2.5 cm) of water every 2 weeks. However, you may need to increase this frequency to once per week during hot summers. The key is to keep the soil moist as deep as the roots grow. Fortunately, the azalea is a shallow-rooted plant so keeping the soil moist to this root depth is simple. Deciduous azaleas and evergreen azaleas both need the same amount of water per week.

How Much Water Do Azaleas Need Per Day?

Daily watering is inadvisable for azaleas to bloom. Azaleas only need to be watered a handful of times a month. Even during hot and dry weather, you’ll rarely need to water more than once a week. Additionally, the amount of water they need per watering is only 1 inch (2.5 cm). Watering azaleas is all about ensuring consistent moisture. Typically, 0.5–1 gallon (1.9–3.8 liters) of water is sufficient for each watering session.

  • Azaleas only need 1 inch (2.5 cm) of water every 2 weeks.
  • You can provide an inch of water by providing 0.5 to 1 gallons (1.9–3.8 liters) of water during each watering session.
  • Mulch with organic matter and provide dappled sunlight to help reduce watering frequency.

Azaleas love cool weather and partial shade, both of which help retain soil moisture. On top of this, you can add a layer of organic mulch to help azalea soil retain moisture even longer. Additionally, deciduous varieties of azalea experience a dormant season in the winter months. Thus this variety of azalea will need much less water in winter.

How Do You Water Azaleas?

Water azaleas from overhead using a watering can or shower setting on a hose. Water until the soil is consistently moist. Use this watering can to control the flow of water. Stop watering before you have soggy soil. Once you have watered, you can test to make sure the water reaches the shallow root system. Insert a finger a few inches deep to verify there is moist soil down to the root ball. 

  • Water azaleas from above using a watering can or shower setting on a hose.
  • Be sure not to overwater and to keep a consistent schedule.

Be sure to establish a consistent watering schedule to keep your plant healthy. You will have to adjust some depending on whether you live in a colder climate or experience warmer weather. Azaleas in hot, dry climates may need more frequent watering and more water per session than those grown in cool and/or humid environments.

Do Azaleas Need A Lot of Water?

Azaleas need relatively little water compared to other plants. Most types of azalea are drought tolerant. So, your azalea can usually grow well in somewhat dry conditions.

  • Azaleas, like other drought-tolerant plants, need relatively little water.
  • Unlike some other plants, azaleas can adapt to dry conditions fairly well.
  • Azaleas have other needs like acidic soil with a pH between 5.0–5.5.
  • Use this soil gauge to test the acidity of your azalea’s soil.

Azaleas do need well-drained soil. Acidic soil is a must as well since azaleas are acid-loving plants. A pH between 5.0 and 5.5 is best for azaleas. Whether you’re growing azaleas in pots or in the ground, make sure the soil has high acidity before planting. If necessary, you can boost soil acidity by adding sulfur or using a high-acidity fertilizer.

Can You Overwater Azaleas?

It is very easy to overwater azaleas. Overwatering can lead to fungal disease and a rotting azaleas root ball. It’s best to avoid these issues by sticking to a consistent watering schedule. You can also use a moisture meter to ensure you never overwater. Use this moisture meter to track the soil moisture of your azalea plants.

  • It’s incredibly easy to overwater azaleas because of how little water they need.
  • Make sure to monitor soil moisture and ensure adequate drainage.

Make sure the meter never goes above the lower end of “moist.” If growing potted azaleas, make sure there is an adequate drainage hole for the indoor azalea plant. Azaleas require water, like all plants, but sitting in soggy, saturated soil can kill your azaleas.

What are the Signs of Underwatered Azaleas?

The earliest warning signs that your azalea lacks water will be that the leaves will dry out and then brown. If left untreated, this can eventually lead to the plant wilting and dying. The good news is that it’s hard to underwater these plants.

  • Underwatered azaleas will experience leaf browning and can eventually die.
  • Because azaleas are drought-resistant, it may take an extended period of neglect before they show signs of drought damage.
  • It can take a long time for azaleas to bounce back from being underwatered.

The best way to revive underwatered azaleas is by reintroducing ideal watering conditions. Because azaleas don’t need much water, it can take more than a month for them to bounce back. Just be patient in applying water every other week and you will see improvement.

How Often Should You Water Azalea Flowers?

Azaleas should be given 1 inch (2.5 cm) of water once every 2 weeks. You can typically provide this amount by watering with 0.5–1 gallon (1.9–3.8 liters) of water. The exact amount of required water can change depending on weather and location. For instance, an indoor azalea will get less direct sunlight and thus need less frequent watering. Here are some important points to remember for watering azaleas:

  • Provide 1 inch of water every 2 weeks (this can change depending on weather).
  • Water azaleas with a watering can or the shower setting of a hose.
  • Azaleas are very easy to overwater due to not needing much water.
  • Underwatering is rare but watch out for browning leaves as a warning sign of underwatering.

With proper watering and acidic soil, your azaleas will thrive. Resist the urge to provide more water or to water frequently—azaleas are easily damaged by wet conditions, so begin with less water and then gradually increase watering if you see signs of wilting, dry leaves.
