Avocado trees can grow more than 80 feet in height. This means they cannot be grown indoors or in smaller yards. However, dwarf avocado trees only grow to a maximum of 10 feet in height, which means they can be grown in smaller yards or indoors.
In this post, you will learn everything important you need to know about the height of avocado trees and how to grow them.
Let’s get to the heart of the matter.
How Big Can An Avocado Tree Get?
The avocado trees most common in the United States can get to a size of more than 80 feet. This is equivalent to more than twenty-four meters. In other words, they can get too big. Too big to grow in small spaces.
If you are wondering how big an avocado tree can get because you want to grow one or more in a small yard or indoors, I have got some good news for you. There are varieties of avocado trees that only grow to a maximum of 10 feet in height. They are known as dwarf avocado trees.
What You Need To Know About Dwarf Avocado Trees
As mentioned in the section above, dwarf avocado trees exist. They are called dwarf avocado trees because they do not grow very tall. While several varieties exist, the most famous one is the Wurtz avocado tree.
This tree is capable of producing avocados from May until early October once it matures. Unlike normal avocado trees that can to more than 80 feet in height, the Wurtz avocado tree rarely grows beyond 10 feet in height.
Because it is a dwarf avocado tree, the Wurtz avocado tree can be container-grown. It, however, requires a big container to thrive. Many experts agree that this avocado is the best avocado for growing in containers.
The Wurtz avocado tree is a hybrid between two key avocado species – the Guatemalan and the Mexican avocado species. It is a stable hybrid that starts producing plenty of avocadoes after just 12 to 24 months of planting when the conditions are right and it is given the care it needs.
Wurtz avocado trees particularly do well in areas that experience mild-winter e.g. parts of California. They like soil that is well-draining, well-aerated, and compost-rich. Therefore, if you want to grow Wurtz avocados in containers, you should make sure you use good potting soil that is all these three things.
And the container should obviously be big enough to accommodate large roots. It should also have holes through which water can drain to avoid waterlogging and root rot.
While it might seem wise to add manure to the potting mix or the soil where you want to grow your Wurtz avocadoes, it is not wise. This is because manure tends to make the ground too salty for the Wurtz trees.
What is important to note about dwarf avocado trees grown in containers is that they need to be watered every day particularly during the hot months of summer. Watering can be minimized during winter to compensate for the reduced evaporation and water loss from the soil.
Wurtz avocado trees and similar dwarf avocado varieties can tolerate 25 degrees F. However, they do best when grown in locations with mild winters or when grown protected inside a greenhouse.
It is also important to note that during summer, Wurtz avocado trees need to be shaded. If they are not shaded, their bark, branches, and leaves will burn. They can be shaded using a greenhouse shade netting. However, this is only necessary for the first 1.5 years. Beyond these years, Wurtz trees often get tough enough to do well in the sun without needing shade.
How To Grow Wurtz Avocado
The Wurtz avocado tree has the potential of providing you with fresh avocados from May to September. The tree is also attractive and will improve the aesthetic of whatever location you position it whether indoors or outdoors.
The best thing about growing this avocado tree or any other similar dwarf avocado tree is that you only need a height of about 10 feet. So you can grow it indoors in a container or outdoors in a greenhouse.
Follow the steps below to grow one or more Wurtz avocado trees.
1. Get Wurtz Avocado Tree Seedlings.
Search online for Wurtz avocado seedling sellers and note the ones nearest to you. After noting the sellers nearest to you, do more research about them to discover who sells the best seedlings and then buy the avocado seedlings from them.
2. Transplant Your Seedlings.
Once you get seedlings from the best seller you could find, transplant them into the ground. Make sure you loosen the ground and use potting soil to give your seedlings a good start.
3. Add A Layer Of Mulch Around Your Seedlings.
Mulch is important for Wurtz avocado trees. Add a thick layer of mulch around your seedlings but not too close to them. This is because the mulch can make the bark of your avocado tree seedlings to start rotting.
The purpose of adding mulch is to cut moisture loss and protect the shallow roots of your seedlings.
4. Irrigate Your Avocado Seedlings Correctly
. You should only water your avocado seedlings when the top two inches of soil are dry. You can confirm this using the finger moisture test. If you wait for the top two inches of soil to dry out before watering, you will only need to water your avocado about twice a week. In some places, you may need to water your avocado tree seedlings more because of the soil and the weather. However, be careful not to overwater them as this could trigger root rot.
5. Feed Your Avocados Correctly.
Feed means fertilize. You should fertilize your avocadoes as recommended by experts if you want the best results. In the first year of growth, you are not supposed to apply any fertilize according to experts. From the second year of growth to the fifth year, you are supposed to fertilize your avocado trees with a 15-15-15 fertilizer.
The fertilizer should preferably be a slow-release fertilizer to ensure your trees get the nutrients they need slowly throughout the year for good growth. Mix the fertilizer with the topsoil about 4 inches from the base of your trees.
6. Mix Zinc Sulfate With The Topsoil Around The Base Of Your Avocado Trees.
You should do this about once every year when the trees are unfurling new leaves. The quantity of zinc sulfate you should apply around every tree is 1.5 pounds. You should mix it thoroughly with the topsoil around 5 inches to the base of every tree and then water the area until it becomes very moist. The purpose of applying zinc sulfate is to prevent stunted growth, improve yields, and kill fungi.
7. Wash Off Dust From The Leaves Of Your Avocado Trees Periodically.
When dust settles on your avocado leaves, it often attracts insects/pests. Therefore, you should periodically wash dust off the top and bottom of your avocado leaves using moderate water pressure. You should also inspect the leaves while washing them and apply a suitable natural pesticide if you notice any pests.
8. Remove Diseased, Damaged, Or Dead Leaves And Branches.
This will help your avocado trees to stay lean and focus their energy on growing stronger and maturing rather than supporting or sustaining non-beneficial leaves and branches
9. Harvest Avocadoes When They Reach Full Size.
If you take good care of your Wurtz avocados as per the guide above, they should start producing avocados in a few short years. You will know they are ready when they reach full size and become easy to remove by a simple twist.
The Final Word
Avocado trees can get as big as 80 feet. This makes them unsuitable for smaller yards and growing indoors. However, there are dwarf varieties such as the Wurtz avocado that can be grown in smaller yards. Follow the tips above on how to grow Wurtz avocado trees.
