Azalea bushes are known for their vividly colored blossoms, long-lasting flowers, and ease of growth in general. They can grow in a wide range of forms and sizes. You want to get one that is suited for your garden. You wonder which Azalea grows fast. How big do Azaleas get? What factors influence the rate of growth of Azaleas? Learn how to get big Azaleas by reading the articles below.
Azalea growth rates
Azaleas can grow up to 10 feet (1 meter) in height, depending on the variety. The average annual growth rate of these shrubs is less than 12 inches. Experts say there are dozens of different Azalea kinds, and their sizes can vary dramatically. Smaller ones might be as short as 12 inches (30 cm). The rate at which their leaves and height grow slower as they get older. Plants that are immature or juvenile grow more quickly than those that are mature.
Factors affecting Azalea growth rate
Let’s look at the aspects that influence Azalea growth rate before addressing the question “How big do Azaleas get?”
Season
Keep track of when you’re going to plant your Azaleas. Your plants are affected differently by each season. Some have positive effects on plants, while others have negative effects.
Azaleas grow quickly during certain seasons, such as spring and summer. In certain cases, they will be dormant and attempting to survive!
If you plant your Azaleas in the winter or fall, don’t expect rapid growth. Plants are resourceful and will conserve their resources.
When the temps begin to rise, they will begin to shoot. This normally occurs near the conclusion of the winter and the beginning of spring.
Transplanting or planting during this time may result in your plants being placed in an unfavorable location.
You may be impeding their ability to develop. As a result, they may become smaller than their species’ norms. This commonly manifests itself as stunted, slow-growing Azaleas.
Azaleas planted in the wrong season will not thrive. Alternatively, they will take a long time to mature and grow to their full size. If you don’t prepare ahead of time when planting your Azaleas, they might never bloom.
Types of Azaleas
A common question about Azaleas when planting and choosing varieties of them is “how big do Azaleas get?”
Deciduous and Evergreen Azaleas are the most common types. The size of Azaleas has something to do with the type of Azalea. Dwarf, medium, and big Azaleas exist.
As a rule of thumb, smaller Azaleas (dwarf Azaleas) develop slowly as a rule of thumb because their maturity size is smaller. Your large Azalea varieties may grow quickly as a result of their enormous mature size.
Let’s take a look at just a few of the numerous possibilities. Here are a few popular choices to help you understand the size range, color spectrum, and hardiness level you may expect to find when you go shopping.
Indica Azaleas
Indica Azaleas, often known as Indian Azaleas, feature big leaves and flowers. Late March to early April is their blooming season. Pure white pink is one of the colors. The height of Indica Azaleas ranges from 6 feet (1.8 meters) to 10 feet (3 meters).
Satsuki Azaleas
About Satsukis, they are resilient, low-growing plants that thrive in all climes. From May to June, they are in full flower. The colors white, pink, and white with a rose-colored border are among the options available. The height of Satsuki Azaleas ranges from 1 foot (0.3 meters) to 3 feet (0.9 meters).
Kurume Azaleas
Kurumes are small, hardy plants that can tolerate freezing temperatures. Their flowering season starts in late March and lasts until early April. White, pink, and red are among the colors available. Kurume Azaleas grow from 1 foot (0.3 meters) to 6 feet (1.8 meters).
Kaempferi Azaleas
Kaempferis are tall plants that can withstand extreme cold. Their flowering season starts in late April and lasts until the beginning of May. White and pink are two of the colors used. The height of Kaempferi Azaleas ranges from 4 feet (1.2 meters) to 10 feet (3 meters).
Flame (Rhododendron Calendulaceum)
Regarding Flame (Rhododendron Calendulaceum), it thrives in zones 5–8. This native bush can grow to be 6 to 12 feet tall and 4 to 8 feet wide. The flower hues are orange, red, yellow, gold, and apricot. It tolerates dry soil once established.
Soil
Azaleas have a precise preference and necessity for acidic soil, which you must adhere to. It’s possible that garden soil is naturally alkaline.
If you want Azaleas to bloom, much less grow in your garden, this is unacceptable.
Growing Azaleas in alkaline or neutral soil will take longer. The amount of time it takes will be reduced if the soil is acidic. This is due to the wide disparity between desirable and unfavorable circumstances.
You’ll need to enrich the soil well ahead of time and before planting. It’s difficult to do this once the Azalea has been planted.
Aluminum sulfate, elemental sulfur, straw, pine needles, and well-rotted compost (1-year-old) are examples of substances that can be used to increase the acidic character (lower pH value) of soil.
Watering
It may appear that watering your Azaleas is simple. When it comes to water, though, there is so much that goes unseen!
Azaleas should be watered with mineral water. These are unlikely to have an adverse effect on the soil. Rainwater is the greatest water for Azaleas to help them develop faster. Azaleas flourish in this type of environment.
Another thing to think about is your watering efforts. Are you adequately watering your Azaleas? Their physical appearance could reveal a lot!
Any yellowing could indicate that your watering efforts aren’t keeping up with your Azalea’s needs.
You’ll have to water your plants differently depending on the season. In the summer, there is more water, and in the winter, there is less. If the weather is warmer, you can also increase the frequency of watering. In the winter, watering should be done less often.
Pruning and mulching
Planting Azaleas in suitable locations and expecting them to thrive in a short period of time is an unrealistic expectation.
This isn’t all these plants require. They are in desperate need of inspiration! This is manifested in the owner’s concern.
Pruning and mulching are two tasks that fall under the area of care.
Actually, pruning is crucial since it encourages growth and gives the plants a shape. Pruning also has the potential to improve flowering. The removal of withering flowers is known as deadheading. It assists in redirecting energy back to the plant rather than these blooms.
Mulching hydrates and fertilizes plants in a natural way. It works by covering and surrounding the Azaleas with a layer of well-rotted debris. Plants will be fed by the progressive leaching of nutrients into the soil. It also aids in the retention of moisture throughout the summer.
Age
Another element people rarely consider when asking “how big do Azaleas get?” is age. You don’t always get young seedlings when you buy Azaleas from a nursery! This is especially true when purchasing an Azalea bonsai!
Growing young, healthy Azaleas might take a long time. When compared to older Azaleas, which will naturally grow less as they mature, this is a significant difference. Azaleas that are more than ten years old will finally stop growing!
Also, the age of Azaleas that have recently been transplanted has an impact on how long they will grow. A healthier, much younger Azalea plant will take longer to grow than an older Azalea plant.
How big do Azaleas get?
Find the right location
Consider what you want to get out of your Azalea plant first. How big do Azaleas get? Is it going to be used as ground cover in front of larger shrubs or trees? Is it going to be a focal point on the porch railing? These responses can assist you in determining the size of the plant you require.
When purchasing Azaleas, read the information tags carefully to determine the size of the plants. Some Azaleas that grow large can be quickly referenced in the information above.
Allow room to grow
When deciding where to plant your Azalea bush, keep in mind how big it will get. To allow for future growth, The Old Farmer’s Almanac recommends spacing plants 2 to 6 feet apart. When arranging Azalea plants next to porches or along with the house, keep in mind how large they will grow. To allow for appropriate plant growth and form, you should plant the shrub at least 2 feet away from the porch or house.
If you’re introducing evergreen Azaleas to an existing landscape, keep in mind the existing plants, shrubs, and trees. You don’t want your Azaleas to take over, suffocate or hide other plants in your yard.
How big do Azaleas get?
All types will only grow to a genetic size limit. A cultivar bred to reach 3 feet in height will not grow much taller. And some cultivars develop more quickly than others. Some can reach a height of a foot per year, while others only reach an inch or two. There are a few things you can do to help your Azalea reach its full potential, though:
- Make sure it can withstand the elements in your area.
- Plant in a suitable area. Although most kinds need dappled sun or morning sun with afternoon shade, some can handle more sun. None of them can survive in utter darkness.
- Check to see if the soil is in good shape. Acidic soil with a pH of 4.5 to 6 is required for these bushes. It’s also necessary to have loamy, well-draining soil.
- After planting, cover your new shrub with a layer of mulch to help it blend in with the forest floor. A 2 to 3-inch mulch layer around your shrub provides nutrients, regulates soil temperatures, and keeps weed seeds at bay. It’s also a good idea to mulch existing plants.
- Regularly water your shrubs. They need about an inch of water per week, which they can get through rain or additional irrigation.
- The use of fertilizer is not essential. They thrive without the need for fertilizer.
Q&A
How long do Azaleas take to get big?
How long will it take your Azalea to grow? Weeks or months? Regrettably, there is no set timetable.
The length of time it takes for your Azalea to mature depends on a number of things. Furthermore, any time frame is based on optimal conditions and care.
Azaleas typically require three years to reach their full mature size.
Gardeners, on the other hand, realize that this is fully dependent on the specific plant! Of course, other elements such as Azalea type, season, soil, watering, pruning, and age all have a role. All of this has already been mentioned.
Can Azaleas be used as a hedge?
For a magnificent spring flower show, nothing beats an Azalea hedge! This style of hedge is a wonderful, low-maintenance option if the conditions are correct. These bushes can also function as a privacy screen.
There are a wide variety of flower hues to pick from, with many of them being fragrant. To add to the wow factor, you can “mix and match” sizes and bloom colors.
An evergreen Azalea hedge is a great privacy hedge, but if you select deciduous varieties, you won’t have that privacy in the winter. The shrubs should not be planted too close together because they demand airflow. If you want a dense, year-round privacy hedge, choose evergreens like arborvitae or yews.
If you desire a formal hedge, Azaleas might not be the best choice. Shearing the bushes may result in the loss of the flowers for the following year. If you want to opt for a more natural aesthetic, Azaleas could be the right alternative.
These stunning flowers can also be used to create a varied border. Combine needled evergreens with other spring bloomers like forsythia or dogwood, summer-blooming shrubs, and shrubs with wonderful fall colors like aronia to make a four-season hedge.
