Overview of Avocado

The Avocado’s scientific name is Persea americana, and the Family name is Lauraceae. As this fruit is less sweet than other fruits, it is very useful for diabetic patients. The shape of this fruit is similar to the guava or pear. Each fruit weighs about 300-700 grams. Inside the fruit are large oval seeds.  Edible parts are buttery smooth with a mildly sweet taste. For the same reason, it is known as butter fruit by many.  There are benefits of eating different fruits like papaya, raw and ripe fruits, vegetables, bars, salads, and sherbets.  Eating avocado cream instead of butter on toast, and eating avocado cream instead of mayonnaise on sandwiches is healthy.

History And Spread

If you are interested in avocado tree cultivation, you may be curious about the origins of this delicious fruit. Avocados are native to Mexico and Guatemala, but they have since spread to many other countries, including the United States and Caribbean nations. Today, Mexico, Chile, Indonesia, and the United States are among the top producers of avocados, with Peru, Kenya, Brazil, Rwanda, and China also contributing significantly to global production. But the popularity of avocado cultivation is spreading, with Sri Lanka, Vietnam, the Philippines, Thailand, Israel, the Netherlands, and India all seeing an increase in avocado production. Even Bangladesh has recently achieved success in growing this fruit. With so many regions embracing avocado tree growth, it’s clear that the love for this tasty and nutritious fruit is truly global.

Avocado Tree Growth Timeline

The growth of an avocado tree can be broken down into various stages. Once planted, it takes around 90 days for the seed to develop roots and become ready for planting. In the first year, the seedling transforms into a sapling, and from years 1 to 3, it undergoes sustained growth when planted outdoors. A healthy avocado tree can grow up to 3 feet per year on average until it reaches its maximum height of 40 feet.

When it comes to fruit production, the method of propagation plays a significant role in the timeline. Growing an avocado tree from seed can take anywhere from 5 to 15 years to produce fruit. However, using a grafted sapling can result in fruit production within 3 to 4 years. It’s important to keep in mind that environmental conditions, pruning, and fertilization can all impact the growth rate and fruit production. Proper care and management can optimize the growth and fruit production of avocado trees.

What is The Best Climate For Avocado Tree Cultivation?

This result is good in tropical, and sub-tropical countries. Rainy, humid, and hot weather during summer is more suitable for fruit cultivation. However, it is hot during fruiting, dry air, and the frost tolerance of this fruit is low. A temperature of 180-250 celsius is more suitable for flowering and fruiting and 250-350 celsius is better for fruit development. Avocado yields well in areas with an altitude of 800-1200 meters above sea level.

Which Soil is The Best for Growing Avocado?

Avocado trees can be grown in almost any type of soil.  A good yield is also obtained in red soil and clay soil, especially with good drainage.  The salt tolerance of this fruit is less. The soil pH level of 5-7 is more suitable for cultivation.  The plant does not have waterlogging tolerance. That is why drainage is convenient, the water level is relatively low, it gets sun all day long and relatively high land is most suitable for growing this fruit.  Soil for avocado cultivation must be fertile and rich in organic matter.

Which Avocado Tree Variety is The Best For Cultivation?

Looking to cultivate avocados but not sure which variety to choose? With hundreds of options available, it can be overwhelming. Avocado varieties can be classified into three groups: Mexican, Guatemala, and West Indian.

Each group has its unique characteristics. The Mexican variety produces small fruit (250 g) with thin, soft skin and high-fat content (30%). It is also frost-tolerant. The Guatemala variety, on the other hand, produces large fruit (600 g) with a long fruit stalk and thick, uneven skin. The West Indian variety produces medium-sized fruit (300-400 g) with a smooth and shiny surface.

Out of these three groups, the West Indian species is most suitable for avocado cultivation. There are many popular varieties among avocado-producing countries, including Hass, Fuerte, Bacon, Reed, Puloc, Jutano, Jan, Linda, and Nabal. However, be aware that cross-pollination can result in new varieties from seedlings. While this can be exciting, the quality of the mother plant may not be maintained, leading to reduced yield and fruit quality.

Propagation Methods:

Generally, there are two common ways of Avocado tree propagation.

1 . Produce seedlings from seeds sexually
2 . The grafting method is a method of producing seedlings

How Do Seedlings Grow From Seed of Avocado?

Successful avocado tree cultivation starts with proper seedling preparation. After harvesting ripe fruit, collect the seeds and plant them immediately in a seedbed. Since the germination capacity of these seeds is limited to 2-3 weeks, it’s important to act quickly. To extend the germination capacity, store the seeds at 50 C. Before planting, prepare a soil mixture of equal parts soil, sand, and coco dust, which provides a fertile environment for the seeds to sprout. Whether planting in a seedbed or tube, proper preparation of the seedlings is crucial for successful avocado cultivation.

Removing the seed coat before planting will increase seed germination. When planting the seeds of this fruit, one should take care to place the broad part of the seed facing downwards. Cover the upper part of the seeds with a thick mixture of coarse red sand and cocoa dust in a ratio of 2:1. It is advisable to treat the soil in the seedbed with fungicide. Ensure that the soil remains rich in nutrients, and irrigate the seedlings regularly during the spring season to promote growth. Seedlings can also grow from seeds planted in cups or plastic bottles with the top cut off, with 30% of the seeds above the water and 70% submerged in the water. Once these seedlings reach a height of 5-7 inches, they should be transplanted into tubs or poly bags to continue growing.

Avocado Grafting Techniques

Choosing a Rootstock

Before you can start grafting your avocado tree, you need to choose a compatible rootstock. The rootstock is part of the plant that will form the roots of your tree. Different avocado varieties have different rootstocks, so it is important to choose the right one for your needs. Some of the most commonly used rootstocks for avocado grafting include Duke 7, Toro Canyon, and Zutano.

Choosing a Scion

Once you have chosen your rootstock, the next step is to choose the scion. The scion is part of the plant that will form the trunk and branches of your tree. You should choose a scion from a mature tree of the desired variety. Look for a scion that is healthy, disease-free, and has a diameter of at least 1/4 inch.

Preparing the Scion

Before you can graft the scion onto the rootstock, you need to prepare it. First, make a clean, angled cut at the base of the scion. The cut should be made at a 45-degree angle and should be about 1 inch long. Next, make a matching cut on the rootstock. The cut on the rootstock should be the same size and angle as the cut on the scion.

Grafting Techniques

There are several different avocado grafting techniques that you can use, depending on your needs and preferences. Some of the most common techniques include whip grafting, cleft grafting, and approach grafting.

Whip Grafting

Whip grafting is a simple and effective technique that is often used for avocado grafting. To whip graft your avocado tree, start by making a diagonal cut on both the scion and the rootstock. The cuts should be made at the same angle and should fit together snugly. Then, wrap the graft union with grafting tape or parafilm to hold the scion in place.

Cleft Grafting

Cleft grafting is another common technique that is often used for larger rootstocks. To cleft graft, your avocado tree, start by making a vertical cut on the rootstock. Then, use a grafting tool to split the rootstock in half. Next, make a diagonal cut on the scion and insert it into the split on the rootstock. Finally, wrap the graft union with grafting tape or parafilm to hold the scion in place.

Approach Grafting

Approach grafting is a more advanced technique that is often used for smaller rootstocks. To approach graft your avocado tree, start by making a small cut on both the scion and the rootstock. Then, place the scion against the rootstock and wrap the graft union with grafting tape or parafilm to hold the scion in place. Over time, the scion and rootstock will grow together, forming a strong graft union.

The success rate of avocado grafting can vary depending on the time of year. Grafts performed during January, February, and early March have been reported to have success rates of nearly 100%. However, success rates during late spring, summer, and early fall are often lower. It is important to note that the success rate may be influenced by several factors, including environmental conditions, the health of the scion and rootstock, and the grafting technique used. Thus, it is essential to use appropriate grafting techniques, maintain optimal environmental conditions, and select healthy scion and rootstock to achieve the highest possible success rate.

Avocado Tree Planting Guide For Cultivation

Choose a sunny and sheltered location: Avocado trees need plenty of sunlight and protection from strong winds.

Planting distance: Planting of saplings/Grafting is usually done at a 20-25 feet distance for making the garden.  A distance of 15 to 16 feet is required for planting a house yard or two rows of trees. In the avocado tree, medium-term mixed fruit (citrus, guava, cool) orchards require a relatively longer spacing of 30-35 feet.

Prepare the soil: Before planting the trees, make a ‘layout’ plan, first determine the designated planting areas and make holes there. Dig a hole that is twice as wide and as deep as the tree’s root ball. Mix in some compost or other organic matter to improve the soil’s fertility and drainage. After making the hole, sunning it for 3-4 days or putting the straw in the hole and burning it with fire will control the diseases and insects living in the soil.

Plant the tree: Carefully remove the tree from its container and place it in the hole. Backfill the hole with soil, making sure the tree is planted at the same depth as it was in its container.

Water the tree: Give the tree a thorough watering to help settle the soil and ensure the roots have enough moisture.

Caring for Your Avocado Trees

Proper care is essential for the health and productivity of your avocado trees. Here are some tips for caring for your trees throughout the seasons:

Spring:

• • Fertilize your trees with a balanced fertilizer to encourage new growth and fruit development.
  • Prune any dead or damaged branches and shape the tree to promote good air circulation and light penetration.
  • Watch for pests and diseases, and treat any issues promptly.

Summer:

• • Water your trees deeply and regularly, especially during hot and dry periods.
  • Mulch around the base of your trees to help retain moisture and suppress weeds.
  • Watch for signs of stress, such as leaf drop or yellowing, and address any issues promptly.

Fall:

• • Continue to water your trees regularly, but reduce the frequency as temperatures cool.
    Harvest ripe fruit as soon as it is ready to avoid overripe or damaged fruit from falling and attracting pests.
  • Begin to protect your trees from frost by covering them with blankets or frost cloth when temperatures drop.

Winter:

• • Protect your trees from freezing temperatures by wrapping them in burlap or other protective material.
  • Prune your trees lightly to remove any dead or damaged branches.
  • Watch for signs of root rot or other issues caused by excessive moisture.

Avocado Planting Timeline For Cultivation:

Avocado seedlings/grafts can be planted at any time of the year if irrigation facilities and drainage are available.  However, if the temperature is low, the roots do not get a chance to spread quickly.  It is better to plant the saplings/grafts in the center of the mother prepared at a height of 10-12 from the ground.  After planting the tree, the tree must be tied with sticks to prevent the tree from falling in the wind and help it to grow evenly all around.

How Much Fertilizer Does Avocado Tree Need To Cultivation?

To ensure optimal growth, plants require a mixture of Nitrogen, Phosphorus, and Potash fertilizers in a 1:1:1 ratio during the growing phase. As soon as flowering and fruiting begin, this ratio should change to 2:1:2. The amount of fertilizer required for each tree depends on its age.

To apply the recommended fertilizers, divide them into two portions and apply each portion at least twice a year. Apply the first portion of fertilizer (50%) between May and June, and the remaining half between September and October, while ensuring sufficient irrigation. Additionally, to supplement any nutrient deficiencies, it is advisable to apply 100-200 grams of mag sulfate, zinc sulfate, ferrous oxide, and boron fertilizers depending on the age of the plants. It is important to note that ferrous sulfate should not be used if the soil pH level is low.

How Do You Increase Avocado Tree Pollination?

In February-March, the tree bears mango-like buds and has a cluster of 200-300 small flowers. Although each tiny flower is bisexual, there is very little chance of pollination by flowers of the same plant. To increase pollination and yield, it is advisable to plant multiple trees in the garden. Avocado varieties are classified into two types based on their male and female flowering conditions. The first is the ‘A’ type. Other species are identified as the ‘B’ type.’A type of female organ is ready for pollination at 8-11 am and the male organ at 3-6 pm the next day. On the other hand, the ‘B’ type female organ is suitable for pollination at 3-6 pm and the male organ at 8-11 am the next day. For the same reason, having A and B-type plants in the garden helps to remove inconsistencies in pollination and helps in fruiting.

Training and Pruning of Avocado Tree:

A training-pruning system at a young stage help to form a trunk up to 4-5 feet and leaves an equal number of branches on all four sides.  Some species of trees grow higher and some species are bushier and have spreading branches that touch the ground below. It is necessary to prevent upward growth in time and to cut down the extra branches if they grow, to ensure free light and air movement in the tree, and to increase the fruit-bearing capacity. However, excessive pruning is likely to reduce yield.

Irrigation Drainage of The Avocado Tree To Cultivation:

Avocados tree do not require much irrigation. The drainage system is more needed during the rainy season.  However, if irrigation is given at intervals of 3-4 weeks during the dry season, the fruit takes longer and the fruit size is larger. It is better to take mulching during the dry season.  This system conserves sap in the soil, controls weeds, and later decomposes them as a source of organic fertilizer to meet the plant’s needs.

Diseases And Pests

Avocado tree growing requires careful attention to tree health as diseases like root rot and leaf spot can impact fruit yield. To protect your trees from these diseases, it’s important to maintain a clean garden environment and avoid water accumulation. Additionally, using effective fungicides such as copper-based fungicides can help keep the trees healthy and productive. By taking these preventative measures, you can ensure the success of your avocado cultivation efforts.

Infestations of mites, mealybugs, scale insects, and fruit flies are occasionally seen on avocado trees. If the attack of these insects is seen, measures should be taken to protect the tree from the insects by spraying a suitable pesticide.

The Yield of Avocado

When it comes to avocado tree cultivation, one question on many growers’ minds is how many fruits they can expect from each tree. Well, the answer depends on several factors, including the tree’s age and variety. On average, avocado trees produce between 200 and 500 fruits each, with no more than 1-4 fruits per bunch or bud. However, some trees may exhibit premature flowering and fruiting, which can result in a smaller harvest. If you do end up with a surplus of ripe avocados, do not worry! You can store them for up to 1-2 months by maintaining a temperature of 5-6 degrees Celsius, giving you plenty of time to enjoy their delicious flavor and nutritional benefits.

Harvesting and Enjoying Your Avocado Crop

The ultimate reward of avocado growing is the delicious and nutritious fruit. Here are some tips for harvesting and enjoying your crop:

• • Harvest your avocados when they are fully mature but still firm. This will ensure the best flavor and texture.
  • To test for ripeness, gently squeeze the fruit near the stem. If it yields slightly and feels soft, it is ready to eat.
  • To harvest, gently twist the fruit off the tree or use pruning shears to cut the stem.
  • Store your avocados at room temperature until they are ripe, then transfer them to the fridge to prolong their shelf life.
  • Enjoy your avocados in a variety of dishes, from guacamole and salads to smoothies and sandwiches.

Conclusion

Avocado tree cultivation can be a rewarding and fulfilling experience, but it requires careful planning and diligent care. By choosing the right variety, planting your trees correctly, and providing them with proper care throughout the seasons, you can enjoy a bountiful harvest of delicious and nutritious fruit. We hope this guide has provided you with the information and tools you need to succeed in your avocado-growing journey. Happy planting!
