How to Grow Your Own Avocado Tree

The avocado Persea americana , a tree likely originating from south-central Mexico, [3] [4] [5] is classified as a member of the flowering plant family Lauraceae. The fruit of domestic varieties has a buttery flesh when ripe.

Depending on the variety, avocados have green, brown, purplish, or black skin when ripe, and may be pear-shaped, egg-shaped, or spherical. Commercially, the fruits are picked while immature, and ripened after harvesting. Persea americana is a tree that grows to 20 m 66 ft , with alternately arranged leaves 12—25 cm 5—10 in long. Panicles of flowers with deciduous bracts arise from new growth or the axils of leaves. The species is variable because of selection pressure by humans to produce larger, fleshier fruits with a thinner exocarp.

Persea americana , or the avocado, possibly originated in the Tehuacan Valley [14] in the state of Puebla , Mexico, [15] although fossil evidence suggests similar species were much more widespread millions of years ago. However, there is evidence for three possible separate domestications of the avocado, resulting in the currently recognized Mexican aoacatl , Guatemalan quilaoacatl , and West Indian tlacacolaocatl landraces.

The earliest residents of northern coastal Peru were living in temporary camps in an ancient wetland and eating avocados, along with chilies, mollusks, sharks, birds, and sea lions. The native, undomesticated variety is known as a criollo , and is small, with dark black skin, and contains a large seed. Janzen concluded that the avocado is an example of an " evolutionary anachronism ", a fruit adapted for ecological relationship with now-extinct large mammals such as giant ground sloths or gomphotheres.

There are some reasons to think that the fruit, with its mildly toxic pit, may have coevolved with Pleistocene megafauna to be swallowed whole and excreted in their dung, ready to sprout. No extant native animal is large enough to effectively disperse avocado seeds in this fashion.

The avocado tree also has a long history of cultivation in Central and South America, likely beginning as early as 5, BC. The plant was introduced to Spain in , Indonesia around , Mauritius in , Brazil in , the United States mainland in , South Africa and Australia in the late 19th century, and the Ottoman Empire inBefore , the avocado was commonly referred to in California as ahuacate and in Florida as alligator pear.

In , the California Avocado Association introduced the then-innovative term avocado to refer to the plant. The modern English name comes from a rendering of the Spanish aguacate as avogato. The earliest known written use in English is attested from as avogato pear , a term which later underwent folk etymology to become alligator pear.

In other Central American and Caribbean Spanish-speaking countries, it is known by the Mexican name, while South American Spanish-speaking countries use a Quechua -derived word, palta. In Portuguese, it is abacate. The fruit is sometimes called an avocado pear or alligator pear due to its shape and the rough green skin of some cultivars. In the United Kingdom, the term avocado pear is still sometimes misused as applied when avocados first became commonly available in the s.

Originating as a diminutive in Australian English , a clipped form, avo , has since become a common colloquialism in South Africa and the United Kingdom. It is known as "butter fruit" in parts of India. As a subtropical species, avocados need a climate without frost and with little wind. High winds reduce the humidity, dehydrate the flowers, and affect pollination. The trees also need well-aerated soils, ideally more than 1 m deep. Commercial orchards produce an average of seven tonnes per hectare each year, with some orchards achieving 20 tonnes per hectare.

Like the banana , the avocado is a climacteric fruit, which matures on the tree, but ripens off the tree. Avocados used in commerce are picked hard and green and kept in coolers at 3. Avocados must be mature to ripen properly.

Avocados that fall off the tree ripen on the ground. Once picked, avocados ripen in one to two weeks depending on the cultivar at room temperature faster if stored with other fruits such as apples or bananas, because of the influence of ethylene gas. Some supermarkets sell ripened avocados which have been treated with synthetic ethylene to hasten ripening. The species is only partially able to self-pollinate because of dichogamy in its flowering. This limitation, added to the long juvenile period, makes the species difficult to breed.

Most cultivars are propagated by grafting , having originated from random seedling plants or minor mutations derived from cultivars. Modern breeding programs tend to use isolation plots where the chances of cross- pollination are reduced. The avocado is unusual in that the timing of the male and female flower phases differs among cultivars. The two flowering types are A and B.

A-cultivar flowers open as female on the morning of the first day and close in late morning or early afternoon. Then they open as male in the afternoon of the second day. B varieties open as female on the afternoon of the first day, close in late afternoon and reopen as male the following morning.

Certain cultivars, such as the 'Hass', have a tendency to bear well only in alternate years. After a season with a low yield, due to factors such as cold which the avocado does not tolerate well , the trees tend to produce abundantly the next season. In addition, due to environmental circumstances during some years, seedless avocados may appear on the trees. Avocados can be propagated by seed, taking roughly four to six years to bear fruit, although in some cases seedlings can take 10 years to come into bearing.

Prime quality varieties are therefore propagated by grafting to rootstocks that are propagated by seed seedling rootstocks or by layering clonal rootstocks. After about a year of growing in a greenhouse, the young rootstocks are ready to be grafted.

Terminal and lateral grafting is normally used. The scion cultivar grows for another 6—12 months before the tree is ready to be sold. Clonal rootstocks are selected for tolerance of specific soil and disease conditions, such as poor soil aeration or resistance to the soil-borne disease root rot caused by Phytophthora. Advances in cloning techniques that can produce up to new plants from a single millimetre of tree cutting have the potential to increase the availability of rootstocks.

Commercial avocado production is limited to a small fraction of the vast genetic diversity in the species. Conservation of this genetic diversity has relied largely on field collection, as avocado seeds often do not survive storage in seed banks.

This is problematic, as field preservation of living cultivars is expensive, and habitat loss threatens wild cultivars. More recently, an alternate method of conservation has been developed based on cryopreservation of avocado somatic embryos with reliable methods for somatic embryogenesis and reconstitution into living trees.

The avocado tree can be grown domestically and used as a decorative houseplant. The pit germinates in normal soil conditions or partially submerged in a small glass or container of water. In the latter method, the pit sprouts in four to six weeks, at which time it is planted in standard houseplant potting soil. The plant normally grows large enough to be prunable; it does not bear fruit unless it has ample sunlight.

Home gardeners can graft a branch from a fruit-bearing plant to speed maturity, which typically takes four to six years to bear fruit. Avocado trees are vulnerable to bacterial , viral , fungal , and nutritional diseases excesses and deficiencies of key minerals. Disease can affect all parts of the plant, causing spotting, rotting, cankers, pitting, and discoloration.

It is normally found on avocado, and in Peru it is said to be the worst insect pest of the fruit. Certain cultivars of avocado seem more susceptible to attack by the scale than others.

Mexico is by far the world's largest avocado growing country, producing several times more than the second largest producer. The avocado was introduced from Mexico to California in the 19th century, and has become a successful cash crop.

Avocado is the official fruit of the state of California. Other avocado cultivars include 'Spinks'. Historically attested varieties which may or may not survive among horticulturists include the 'Challenge', 'Dickinson', 'Kist', 'Queen', 'Rey', 'Royal', 'Sharpless', and 'Taft'.

A stoneless avocado, marketed as a "cocktail avocado," which does not contain a pit, is available on a limited basis. They are five to eight centimetres long; the whole fruit may be eaten, including the skin. It is produced from an unpollinated blossom in which the seed does not develop.

In , world production of avocados was 7. Seventy-six percent of Mexico's avocado exports go to the United States, [71] with the free trade agreement between the US, Canada and Mexico in July facilitating avocado shipments within the North American free trade zone. During the COVID pandemic , Mexican avocado farmers restricted harvesting as the overall demand and supply chain slowed due to labor and shipping restrictions. The fruit of horticultural cultivars has a markedly higher fat content than most other fruit, mostly monounsaturated fat , and as such serves as an important staple in the diet of consumers who have limited access to other fatty foods high-fat meats and fish, dairy products.

Having a high smoke point , avocado oil is expensive compared to common salad and cooking oils , and is mostly used for salads or dips. A ripe avocado yields to gentle pressure when held in the palm of the hand and squeezed. The flesh is prone to enzymatic browning , quickly turning brown after exposure to air.

The fruit is not sweet, but distinctly and subtly flavored, with smooth texture. The avocado is common in vegetarian cuisine as a substitute for meats in sandwiches and salads because of its high fat content. Generally, avocado is served raw, though some cultivars, including the common 'Hass', can be cooked for a short time without becoming bitter. The flesh of some avocados may be rendered inedible by heat. Prolonged cooking induces this chemical reaction in all cultivars.

It is used as the base for the Mexican dip known as guacamole , [3] as well as a spread on corn tortillas or toast, served with spices. Avocado is a primary ingredient in avocado soup. Avocado slices are frequently added to hamburgers and tortas and is a key ingredient in California rolls and other makizushi "maki", or rolled sushi. In the Philippines , Brazil, Indonesia , Vietnam , and southern India especially the coastal Kerala , Tamil Nadu and Karnataka region , avocados are frequently used for milkshakes and occasionally added to ice cream and other desserts.

Chocolate syrup is sometimes added. In Morocco , a similar chilled avocado and milk drink is sweetened with confectioner's sugar and flavored with a touch of orange flower water.

In Ethiopia , avocados are made into juice by mixing them with sugar and milk or water, usually served with Vimto and a slice of lemon. It is also common to serve layered multiple fruit juices in a glass locally called Spris made of avocados, mangoes, bananas, guavas, and papayas. Avocados are also used to make salads.

Avocados in savory dishes, often seen as exotic, are a relative novelty in Portuguese-speaking countries, such as Brazil, where the traditional preparation is mashed with sugar and lime, and eaten as a dessert or snack. This contrasts with Spanish-speaking countries such as Chile, Mexico, or Argentina , where the opposite is true and sweet preparations are rare.

How to grow an avocado from seed

Interciencia , vol. Abstract: We studied the effect of foliar applications 0, 0. Hass trees. Penetration of foliar B application 0. The increasing levels of B applied in three successive occasions with 20 days intervals did not affect the concentration of this element in leaves, sampled 15 days after the application. There was no effect of B on the concentration of carbohydrates. After the second sampling, there was a positive relationship between the concentration of B applied and the amino acids concentration.

Like many citrus trees, avocado trees grow very well grown indoors. Visible signs of damage can be brown spots on leaves or scarred fruit.

Avocado Tree Not Producing Fruit: 9 Common Reasons and What to Do

Avocado trees Persea americana are notorious for being susceptible to cold. Of the three subspecies more on this later of avocado, the least commonly grown one — the Mexican variety — has a number of cultivars that can tolerate frosts. We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission. The lowest area of hardiness where you can grow avocados is Zone 8. If you live in Zone 7 or below, you would need a large greenhouse to successfully grow an avocado tree. Having conducted lab research on avocado trees for 14 years, I am often asked what varieties will grow in colder areas, and I am delighted to provide this guide to answer that question. Subspecies are a broader classification than varieties or cultivars. They encompass plants or animals that have developed in response to their natural environment in isolation from other populations of the species.

Avocado Leaves Curling (And How To Fix It)

I'm surprised you didn't mention the Duke, but then again, finding one of those trees is a Herculean effort since you are literally forced to make your own. But I will never forget the sight of healthy Duke grafts -- not a scratch on them Fred -- protruding from half dead, sickly looking root stock that nearly perished from the cold last winter. I have my Duke tree planted on the southwest side of the house -- not far from the house either -- where it will be protected from the cold, northerly winds. It's also in a raised bed with no other plant -- no competition.

Give trees full sun and shelter from frost and strong winds.

Why Avocado Trees Won’t Flower or Fruit

Native to southern Mexico, avocados Persea americana are subtropical trees that grow best in semi-humid climates in zones 9 to 11, with temperatures ranging from 60 to 80 degrees Fahrenheit. This makes these trees ideal for California's coastal climate, where the weather stays moderate, and doesn't get too hot in summer. Avocados become less productive in temperatures of degrees Fahrenheit. Above is a Southern California garden, where an avocado tree grows near a red Japanese maple just starting to leaf out for the spring. The avocado tree has lots of new flowers blooming for future harvests. Avocado trees grow best in full sun in a fine sandy loam soil with excellent drainage.

Don't toss that avocado pit — with a little patience, you can sprout the seed to plant and grow an avocado tree. It'll make a lovely houseplant that may someday pay you back with fruit. Growing an avocado from a pit starts with sprouting. The only skill you need to coax that hard avocado seed aka the pit to crack is patience — because it usually takes six to eight weeks to get a sprout.

They may take a little extra work to grow in Texas, but the rewards are worth it! Please note that the winter hardiness stated is for trees established for 3 years or more.

Origin: Avocados are indigenous to tropical America. Distribution: Avocados are grown in tropical and subtropical areas of the world. In Florida, commercial production is primarily in Miami-Dade and Collier Counties Figure 1 , however, small plantings and isolated trees are found in warm locations throughout the state. History: Avocados have been cultivated in tropical America since pre-Columbian times. The first recorded importation into Florida was in and into California in

By enclosing them into glass forms, tree and vine fruits can be forced to grow into squares, stars, hearts or any other funny fruit form. Any clean, airtight container will work.
