How Do I Start An Avocado Tree From A Seed


Avocado trees are one of the most fun and rewarding plants to grow. But starting an avocado tree from a seed is often a difficult and confusing process. For those looking to start an avocado tree from a seed – it can be daunting. This guide focuses on providing some basic background information, relevant data, and perspectives from experts on starting an avocado tree from a seed. It also offers personal insights on the matter that can be both educational and engaging for the reader.

Getting Started

The first step to begin is to select a good and healthy seed. The best avocado seeds are the oval ones, which are smooth-skinned and unblemished. The bigger the seed, the better the quality. Once you’ve obtained a seed, clean off any dirt and place it in a bowl with lukewarm water. Allow the seed to soak for several hours, or even overnight. After it has been sufficiently soaked, the seed can be planted in a pot of soil, as long as the soil is well-draining.

Care Instructions

Once the seed is planted, it can take several weeks for it to sprout. During this stage, the seed should be kept in a warm, sunny spot, and watered regularly; however, excessive amounts of water should be avoided, since it can encourage fungal diseases. To ensure maximum growth, use a fertilizer to supplement the soil’s nutrients. Over time, the seedling will start to form leaves and roots, and eventually grow into a full-sized tree.

Nursery-Bought Trees

Alternatively, you can purchase a ready-made avocado tree from a nursery, which is a great option if you don’t want to spend a lot of time starting a tree from a seed. While it may cost more, it’s much easier, and you don’t have to worry about any potential failures. Nursery-bought trees should be treated with extra attention and allowed to adjust to their new environment before bearing fruit, which can take at least two or three years.

Environmental Considerations

Due to their origin as tropical plants, avocado trees need lots of sun and warmth to survive and produce fruit. The best climate for them is a temperate climate with mild winters and warm summers. Additionally, they require consistent moisture throughout the year, so if you’re in a dry area, daily watering might be necessary.

Different Varieties

Avocado trees come in a variety of sizes and shapes, depending on their variety. From the large, traditional varieties to the more compact, dwarf trees, there’s something to fit every need and space. Some of the more popular varieties include the Hass, Fuerte, Bacon, and Pinkerton avocado trees.

Growing Conditions

Avocado trees have very specific cultivation requirements; they favour sandy, well-draining soils, and adequate water and fertilizer. Additionally, proper pruning techniques must be employed to keep the trees from becoming too large or unruly. Due to their heavy-bearing nature, avocado trees require regular pruning to keep them healthy and maintain their shape.

Container Growing

If space is an issue, growing avocado trees in containers is possible, although some care and vigilance are required. The containers need to be deep and wide enough to support the roots and to hold soil moisture, and should be placed in a sunny spot. In addition, container-grown trees will require more frequent watering, since the soil dries out more quickly.

Pests and Diseases

Avocado trees are susceptible to a number of pests and diseases, including root rot, trunk borers, and several others. To treat these problems, it’s important to identify the cause and take steps to control the problem. For root rot, fungicides can help, while for borers, 4-5% horticultural oil can be applied to the trunk.

Harvesting and Storage

When the time comes to harvest the avocados, they should be left on the trees until they’re ripe. When ripe, they should be picked very gently, as they are fragile and easily bruised. After harvesting them, they need to be left at room temperature in a cool, dark place until they can be consumed or stored in a refrigerator to stay fresh for longer.


Grafting is a process used to combine two plants, in this case a rootstock and a scion. This allows you to grow a variety of avocado that may not be well suited to soil conditions in your area. For instance, you can graft an avocado from Mexico or Hawaii onto a tree from Florida and produce fruit from the tree that is adapted to the Florida environment.

Seeds vs Seedlings

When deciding whether to start an avocado tree from a seed or a seedling, the first thing to consider is the amount of time and effort required. Starting from a seed is more time-consuming and there is a greater chance of failure, but it’s also more affordable. With seedlings, the process is much easier and faster, but you’ll need to pay for the seedling itself.


Rootstocks are the roots of an avocado tree, which can be combined with a desired scion (the top part of the tree) in a grafting process to create a new tree. Rootstocks have many advantages; they help reduce the size of the tree, they increase its disease resistance, and they can make a tree hardier in difficult climates.

Organic Growing

Organically grown avocado trees are increasingly popular, as organic fertilizers and pesticides can be used in place of more traditional treatments. Organically grown trees also require fewer resources, such as water and fertilizer, and can be a great way to protect the environment and reduce your carbon footprint.


Avocado trees need regular fertilization to provide them with the necessary nutrients for optimum growth, fruiting, and health. The amount and timing of fertilizer application will depend on the tree’s age and growth stage. Generally, nitrogen-rich fertilizers should be applied during the growing season and calcium-rich fertilizers should be applied after harvesting.


Avocado trees should be pruned regularly to keep them healthy and attractive. Pruning can be achieved through either topping or thinning. Topping involves cutting off the tree’s crown, while thinning involves removing some of the branches to increase air circulation. Proper pruning will ensure healthy, productive trees with high yields.

Fruit Production

The amount of time it takes for an avocado tree to start bearing fruit depends on many factors, such as the variety, the location, the climate, and the care. Generally, a well-established tree will start to bear fruit in 3-4 years, while a newly-planted tree may take 7-10 years or longer.


Starting an avocado tree from a seed is a rewarding process that can be an enjoyable way to spend your time. With a little patience and care, it’s possible to have a thriving avocado tree in your garden. Nevertheless, starting an avocado tree from a seed is a challenging process, requiring knowledge and dedication, and in many cases, expert help.
