Do you want to grow avocados as houseplant but concerned about how tall they will grow? You might also be worried if you grow them in your garden. Because if the trees fail to reach average height in due time, you may not get the expected number of fruits. But don’t worry, I’ll try to explain this issue as much as possible with my practical knowledge.
Avocado trees can grow up to 15 to 20 meters or 50 to 70 feet in height if you can provide the necessary care. In some cases, the trees can even cross 80 feet tall. But if you grow trees from a seed as a houseplant, their height will be much smaller compared to the garden or nursery trees.
Along with the environmental influence, it is your nurturing process that can affect the growth of the trees. You will eventually notice that regular care and preventive measures can enhance the growth of both standard and dwarf trees. Provided you can take enough care, you will receive more avocado fruit at the end of the season. So, follow along with us if you want to know more about how to enhance the growth of your grace to obtain better results.
What are Dwarf Avocado Trees and How Tall Do They Grow?
As you can guess from the name, these dwarf trees do not grow much tall. There are several types of avocado dwarf trees but the most popular one is the Wurtz avocado tree. You will find that in certain parts of California, these trees grow well in mild winter months. These dwarf trees can produce fruits from May to October as they become mature day by day. Compared to the standard trees that grow up to 80 feet in height, these dwarf trees cannot grow more than 10 feet.
You can easily grow these dwarf trees as a houseplant in a container. You will even get feedback from gardeners that the Wurtz avocado is the best one to grow indoor. If you can provide the necessary care and take precautions, you will receive a significant number of fruits within 12 for 24 months after plantation. So, be sure to contact any local gardener and check your local nursery or garden centers if you want to start growing avocado plants.
How to get Dwarf Avocado Trees to their maximum height?
- Provide them with such a soil that has adequate drainage, rich with compost, and has enough air pockets. Make sure you fulfill these three criteria if you want to grow the dwarf varieties in homemade containers.
- Always choose such a container to grow a dwarf variety that can accommodate their large root system. The dwarf avocado plants have a larger root structure than any other plants like their height.
- Make sure that there are enough water drainage holes at the bottom of the container. In this way, you can prevent waterlogging and root rot.
- You may have already known that adding manure in the soil or potting mix for standard avocado trees is good for their growth enhancement. But in case of dwarf trees, do not add manure and excess fertilizer because it will possibly make the soil too salty for the root system.
- Water the avocado trees every day, especially during the hot summer months. You can lessen the amount of water during winter as there is less evaporation and water loss from the soil surface.
- Provide adequate light but remember that these dwarf varieties can tolerate up to 25 degrees Fahrenheit temperature. However, you will find it convenient to grow them in locations with mild winters.
- Provide your trees enough shade during summer. If you fail to provide necessary shade from bright light in time, it is possible that the branches, bark, and leaves will burn. You can also use greenhouse shade netting for the first one and half years after plantation. After that, they will eventually get strong enough to take direct sunlight without requiring shade.
Factors that decide the Height of a Standard Avocado Tree:
As you start to grow avocado trees in your garden, you will eventually notice that there are significant factors that can affect the height of those trees. If you can take good care during the juvenile period of growth, be confident that your trees will have a good height bearing an abundance of fruits. Read about these factors carefully to understand what decides the height of your trees.
- Varieties of Avocado:
Keep in mind that different varieties of avocado trees have different heights. Along with the variety, the weather and atmosphere around the trees can affect its growth. You can find dwarf and standard varieties. There are also differences regarding the flowering of fruits.
You can easily find nursery-grown trees of standard varieties in your local garden centers. For example, Guatemalan, Mexican, and West Indian are the prominent ones. In case of dwarf varieties, the Wurtz avocado is the ideal one to grow as indoor plants. They reach a height of up to 10 feet only.
Depending on the maturity rate and size of fruits, the average height of the trees will be around 30 and 40 feet and in width about 15 to 20 feet. However, in some cases, you may find that the trees can even grow up to 80 feet in height.
Remember that avocados are divided into two groups based on flower types. These are A-type and B-type. The trees carrying A-type flowers shred pollen in the afternoon and become receptive to pollen during the morning. On the other hand, the trees carrying B-type flowers work vice-versa.
You may find Stewart, Mexicola and Hass etc. which are good examples of A-type flowers. Also, Zutano and Bacon are popular for B-type flowers. These types of avocado flowers are very popular among gardeners.
- Shape of Trees:
Although you might think the shape of a tree doesn’t have anything to do with its size, it has an impact upon it. If you consider an avocado tree, check its canopy. You will find its shape regular, symmetrical, and smooth. In this case, its branches and leaves are usually filled in the crown following a uniform fashion. The trees will continue to grow more like a pyramid shape in the initial stage and get rounded as they become old.
- Rate of Pruning:
You must not over prune the lateral branches; it may impact negatively on the growth of the tree. Although cutting some random branches here and there might look efficient at the beginning, the trees will seriously get damaged if you cut too much. As a result, it will require a recovery period that will slow down the growth. So, always take precaution when you prune the branches of the tree and try not to damage it.
- Age of the Trees:
If your avocado trees are middle aged or younger, they will follow a pyramid shaped structure, and the top of the trees will become round gradually as time passes.
- Growth Rate:
The trees will have a quick growth rate if your avocado trees are grown from grafted avocado plants of nursery or gardening centers. On the other hand, if you grow trees from seed, it is a very time-consuming process that can take up to 15 years for the young plants to become mature trees. They can grow more than two feet tall in a single season and gain maturity within 20 years.
- Climate & Temperature:
Don’t let your trees get exposed to freezing temperatures. This harsh and cold climate can cause your trees to die to the ground. Always grow avocado trees in a warmer temperature. This will allow a higher growth rate. But if you continue to grow in cold weather, it will slow down the growth process. As a result, the trees will require a longer time to gain maturity, attain maximum height and give you fruits.
Avocados are considered as one of the most sensitive trees to grow as a houseplant. That is why, you must take precautions and nurture them properly so that they can reach their maximum height in due time. Only after that can you expect them to become mature and provide fruits every season. Nevertheless, don’t lose hope and always be patient while growing from an avocado seed. We hope that all your hard work and patience will get rewarded with an abundance of wonderful fruits.
