Avocado Persea americana
ABOUT
Persea americana, also known as the avocado, is a large, evergreen tree that belongs to the flowering plant family Lauraceae. The tree typically grows to be 70 feet tall, although when grown in a container or as a dwarf tree, it can be much shorter.
The leaves of Persea americana are glossy and dark green, simple, and oval in shape. They are typically around 2-6 inches long, with a leathery texture. The leaves grow in an alternate pattern on the branches and have a smooth edge.
The tree produces small, greenish-yellow flowers that grow in clusters. The flowers are inconspicuous, not showy and have no fragrance.
The fruit of Persea americana, commonly known as the avocado, typically has a green, pear-shaped or oval shape, with a rough and bumpy skin. The skin of the avocado can be thick or thin, depending on the variety, and can range in color from green to almost black when ripe. Inside the fruit, there is a large central pit, called the seed, that is surrounded by a creamy, green flesh. The size and weight of the fruit can vary greatly depending on the variety, some avocados can be small like a golf ball, others can be large and weigh more than a pound.

- Toxicity
To humans
The fruit of Persea americana, also known as avocado, is generally considered to be safe for human consumption.
The fruit, leaves, bark, and seeds of the avocado plant contain a chemical called persin, which in high concentrations can be toxic to animals. However, persin is not harmful to humans when consumed in the small amounts found in avocados.
Ingestion of the leaves, bark or seed in large amount can cause stomach upset, vomiting and diarrhea in humans, it's best to avoid consumption of those parts of the plant.
It's also important to note that the skin and leaves of avocado tree can cause skin irritation and allergic reaction in some people.To pets
Persea americana, also known as avocado, is generally considered to be safe for human consumption but some parts of the plant can be toxic to certain animals. The fruit, leaves, bark, and seeds of the avocado plant contain a chemical called persin, which in high concentrations can be toxic to animals.
Persin can cause serious health problems for some animals, such as horses, cattle, and birds. Ingestion of avocado leaves, bark, or fruit can cause respiratory distress, congestion, fluid accumulation around the heart and lungs, and even death in some cases. Other animals such as dogs and cats, the ingestion of avocado can cause stomach upset and vomiting, but is not likely to be fatal.

The avocado tree is an evergreen and produces fruit year-round, and in some cultures, it is associated with wealth, abundance and love. The avocado fruit is also rich in fat which is why it's also associated with richness and plenitude.
- Water
In general, avocado trees should be watered deeply and infrequently.
A good rule of thumb is to wait until the top inch of soil is dry before watering again. For young trees, you should water them every 7-10 days during the growing season, for mature trees it may be less frequent.
It's important to avoid over-watering, as this can lead to root rot. In addition, it's important to make sure that the soil has good drainage and that the tree is planted in a spot that does not retain standing water. - Light
The best light conditions for avocado tree is bright indirect light.
They can tolerate a little bit of direct sunlight, but they prefer filtered light, they can grow well near a window that gets indirect light. - Temperature
The avocado tree is a tropical plant, it prefers warm temperatures and they need to be protected from frost.
The ideal temperature range for an avocado tree is between 60-85°F. They can tolerate temperatures as low as 32°F for short period of time, but prolonged exposure to freezing temperatures can damage or kill the tree. If you are growing avocado tree indoor or in a container, it's important to provide a warm, bright location and to protect it from cold drafts. - Pruning
Pruning an avocado tree can help to promote healthy growth and fruit production. The best time to prune an avocado tree is in the late winter or early spring, before new growth begins. Prune to remove dead, diseased, or damaged wood, and to shape the tree for optimal fruit production. Start by removing any dead, diseased, or damaged wood. Then, prune to shape the tree, focusing on removing any branches that are crossing or rubbing against each other. Avoid removing more than 25% of the tree's canopy at one time.
- Cleaning
Every few weeks
- Soil
The best soil for avocado trees is well-draining, loamy soil with a slightly acid to neutral pH between 6.0 and 7.0. Avocado trees prefer soil that is rich in organic matter, such as compost or well-rotted manure.
It's important to ensure that the soil has good drainage to avoid root rot. You may want to consider amending your soil with coarse sand, perlite or other materials to improve drainage if your soil is heavy clay or tends to retain water. - Repotting
Avocado trees do not need to be repotted frequently as they are not known for growing very fast.
For young avocado plants, it is suggested to repot them once a year or when the roots have outgrown their container until the tree reaches the size desired or appropriate for the location. For mature avocado plants, repotting is not needed, instead regular checking of the root condition and removing the old soil and adding new soil every 2-3 years is enough. - Humidity & Misting
Avocado trees prefer humidity levels between 40-60%.
If grown indoors or in a container, it's important to mist the leaves or place the tree on a tray of moist pebbles to increase humidity levels. It's also important to keep the tree away from dry air, heat sources and drafts. - Suitable locations
Indoor
Avocado trees can also be grown indoors as houseplants or in containers. They can be grown as a small tree or bonsai.
To grow indoors, choose a dwarf variety or a grafted variety that will stay small. Avocado trees grown indoors will need bright, indirect light and should be kept away from cold drafts. They also need to be fertilized and watered regularly, and misted to increase humidity levels.Outdoor
Avocado trees can be grown outdoors in subtropical or tropical climates with warm temperatures and adequate rainfall.
They should be planted in well-draining soil in a spot that gets partial to full sun. Avocado trees can reach up to 60 feet tall and 40 feet wide, so they need plenty of room to grow.Hardiness zone
8 - 10 USDA
- Life cycle
The avocado tree begins its life cycle as a seed. The seed germinates when it is exposed to proper temperature and moisture conditions, and a root and stem emerge.
After the seed has germinated, the seedling begins to grow. It produces a main stem and two lateral branches which produce the first leaves. The leaves are arranged in a whorled pattern, and the tree continues to grow rapidly.
After about three years of vegetative growth, the avocado tree begins to flower. Avocados are self-fertile, meaning they do not require pollination from other trees. The tree produces small, greenish-yellow flowers that are arranged in panicles.
If the flowers are pollinated, the ovary of the flower develops into a fruit. The fruit of the avocado tree is a large, pebble-skinned drupe. Once the fruit is mature, it can be harvested.
Once the avocado fruit is mature, it can be eaten or the seed can be used to propagate new trees. The seeds can be dispersed by animals, water or wind.
The avocado tree can also regenerate itself by sprouting new seedlings from the roots. This process is called “suckering.” The new seedlings can then be transplanted or left to grow and form new trees. - Propogation
Propogation time
Late winter - early spring
By SEEDS:
Seed propagation is the most common and cost-effective method of propagating avocados. To propagate from seed, the avocado should be de-pulped and allowed to dry for a few days. Once the seed is completely dry, it should be planted in a pot filled with a well-draining soil mix and lightly covered with soil. The seed should then be kept moist, warm, and well lit until it sprouts (which usually takes about 4-6 weeks).
By GRAFTING:
Grafting is a slightly more complicated technique which involves attaching a scion (a piece of stem or branch from an existing avocado tree) onto a rootstock (the roots of a different avocado tree). The scion and rootstock should be carefully matched so that they are approximately the same size and age. Grafting is used to propagate avocados with specific characteristics that are desirable.
By CUTTINGS:
Cutting is another propagation method which involves taking a cutting (a piece of stem or branch) from an existing avocado tree and rooting it. To do this, the cutting should be taken from a healthy, mature avocado tree and should be about 6-8 inches in length. The cutting should then be allowed to dry for a few days before being planted in a pot filled with a well-draining soil mix and lightly covered with soil. The cutting should then be kept moist, warm, and well lit until it sprouts (which usually takes about 4-6 weeks).
By LAYERING:
Layering is a propagation method which involves rooting a branch that is still attached to the parent plant. To do this, a branch should be bent down and covered with a layer of soil. The branch should then be kept moist and warm, and should be left in place until it has rooted (which usually takes about 4-6 weeks). Once the branch has rooted, it can then be cut from the parent plant and transplanted.
