hello
Hello, everyone
I'm Xi Xiaochu loving grow vegetables
Last month I shared how to grow avocados from seed in boxes
A lot of friends are interested in
How does the avocado tree bear fruit
So let me share it with you today
The Mystery of Blossom and Fruiting of Avocado Trees
This is since I started growing avocado 10 years ago
What we've learned so far
A magical and unique mystery of flowering and fruiting of avocado tree
In this video
I share three major issues
How many year to takes an avocado trees bear fruits
Why some avocado trees only blossom but do not bear fruit
And the types and varieties of avocado trees
What it does to the tree fruiting
This video will be very informative

All right
Not much to say
Let's get down to business now
First question
How many years to takes avocado trees to bear fruit?
The avocado tree that our family grows
There are two kinds of planting methods
One is planted with seeds
That is to say, seedlings
Just like I did in my last video
The avocado seedling seeded with a stone
The other is grafting
avocado trees grown in these two ways
The results are vary widely
Let's talk about seedlings firstly
A seedling sown and propagated by seed
avocado trees grow very long in their infancy
The age at which a tree can bloom and bear fruit
In different planting conditions and different varieties
There are also big differences
It takes six to eight years to bloom
Under normal conditions, flowers are seen to bloom in more than 10 years
And the fruit trees from which the seedlings were planted
Even if it blossoms
The resulting fruit may also mutate
The quality is not as good as it used to be
Therefore, the use of seedlings need a long time to wait
But also prepared that the fruits
Not asgood quality as you might think
So this kind of seedling that comes from the seed
In addition to being able to beautify the environment inside and outside the room
It's not like there's no other use
It can be used as a stock for grafting
In order to accelerate that fruit tree into reproductive growth
That is, the process of flowering and bearing fruit
Allowing avocados to produce results many years in advance
Either the bud method or the branch method can be used
A grafted avocado
It can bloom in 3 - 4 years
In tropical regions where climatic conditions are very suitable
The flowering will begin much earlier
Some will flower in the second year after grafting
So think about the avocado fruiting
I suggest planting grafted seedlings
If you don't have the resources to graft
You can also go to any nursery to buy a grafted tree
Like this one I have
Is to grafted seedlings I bought
Bought back the second year and began to bloom
And the other one next to it
This one is a seedling from seed
I planted it myself with a pit
No grafting
It's been four years now
still in the early stages
No flowers ever bloomed
of course no fruits
It's been pruned twice
Topped off at a height of nearly half a meter
And then split two
Branch's up there
This year
I topped off the branch again
Because the variety of this fruit tree is very tall
I don't want it to grow too tall
Therefore, the cutting of avocados is also necessary
Otherwise some of its varieties can be as high as 10 meters
That you can't even reach
I'm going to choose some suitable varieties this year
Try grafting these seedlings with seeds
At that time, I will share the grafting process with you
Interested friends, don't forget to keep an eye on it
But
I guess there are a lot of people who have been in similar situations with me
Is after flowering the avocado tree does not bear fruit
why
Like this one next to me is a graft
It's been blooming for two to three years
There's a lot of blooms
There are a lot of bees around
The florescence is also particularly long
It can last three to four months
Theoretically, it can produce a lot of fruits
But there was not a single fruit
why
After a lot of research
I finally realized the real reason why only flowers don't bear fruit
Let's take a look at it together
Why some avocado trees don't bear fruit when they bloom
To know the reason
Let's start with the avocado's habit of flowering and bearing fruit
Avocados are different from other fruit trees in their habit of flowering and bearing fruit
The flowers of avocados, though, like many, are full flowers
That is, the same flower has both pistil and stamen
This is called a total flower
But the pistil and stamens in the same flower
But not all at the same time
So its flowering is very special in the fruit tree
The same flower will bloom twice
They open and close in turn every day
Take the same flower
It can open it up and
Close it twice
At the first opening
The gynoecium in the flower will ripen
But at this time the stamens are not mature
So they don't send out pollen
The petals will close after half a day
At the second opening
The stamens are ripe
But by this time the pistil had withered
There is no ability to receive powder
Half a day later
The petals will close again
This pistil and stamen do not mature at the same time
It caused the flowers to bloom on the same tree
But you can't get it
Of course it won't work out
This avocado tree
It's the only avocado tree that's in bloom in my family now
Combine what I just said with the way it blooms
He won't have a chance to get it
So it won't work out
So here's the question
How can an avocado be pollinated
Now the point is made
Please listen carefully
According to the variety of the original
Avocados of different varieties
Pistils and stamens mature at different times
People follow the time of maturity of the pistil and stamen
Avocados are divided into two types of flowering
Type A and type B, respectively
Now let me first introduce
The characteristics of these two types
Let's start with type A
Flowers of type A avocado trees
The first flower blooms in the morning
The pistil is now mature
ready to go
But the stamens are not mature at this time
No pollen
Around noon
The flowers will close for the first time
In the afternoon of the same day or the next afternoon
The flowers will bloom again
At the second blooming
The stamens are ripe
It's giving off pollen
But the stigma of the pistil has withered
There is no ability to receive powder
In the evening
The flower will close a second time
This type A flowers from starting flowering to full maturity
It will take about thirty to thirty-six hours
From the morning of the first day to the evening of the second
This is the blooming time and characteristic of Type A flowers
Now let's talk about type B flowers
Flowers of avocado tree of type B
The blooming time is exactly the opposite of type A
The first blooming time was in the afternoon
The pistil is now ripe
But stamens do not mature
There is no pollen
The flowers close for the first time in the evening
In the morning of the next day
The flowers undergo a second bloom
At this time the stamens are mature
And release the pollen
But the pistils are dead
At noon the flowers will close for a second time
Complete the entire florescence
This type b flower to fully mature
It takes a little less time than type a
About twenty to twenty-four hours
Bloom from the afternoon of the first day
Till noon the next day
So you may have know it
According to ab these two types of avocado tree flowering characteristics
The best way to get avocado trees pollinated
It's the simultaneous planting of both types of A and B
That means you should at least plant
Two different types of avocado trees
One type A
One type B
To make sure it's pollinated
Can get fruits
When type A flowers first bloomed in the morning
Mature
A pistil capable of being pollinated can be found
Type B has been bloom for the second time
The stamens in a flower that exude pollen
The flowers on these two trees can fall in love and get married
Whether it was insect pollination
Or artificial pollination
It's easy to pollinate anyway
This is the usual way that avocado trees can produce a lot of fruit
Is also a fruit farming practice
The species of the flowering avocado tree beside me is
Bacon
It is a type B avocado
So if you want it to work out
A type A avocado needs to be planted next to it
In fact, the one next to it is a type A
It's Haas
But since it's still young
No grafting
There is no blossom
So there's no match yet
So I've actually bought another one called a wurtz
avocado trees
It's type A too
But it could be affected by the Covid
It hasn't been delivered yet
So I missed out fruiting chance again this year
We can only hope for next year
Of course someone's gonna ask
Sometimes there is only one avocado tree
There is no other type of avocado around
We're not supposed to be able to pollinate
It's not gonna work out
In fact, there are some such cases
Pollination of individual plants will generally occur in the following circumstances
What kind of situation
It's a cross pattern
This is especially true when climate conditions change
Be affected by climate and weather
Flower opening time may be delayed or advanced
Resulting in the maturity of the pistil and stamen
There are overlapping phases
There are mature stamens and pistils in the same tree
A co-existing condition
This leads to pollination
Can single bead results according to the above
For example, type A is the first time to bloom in the morning
Pistils are ripened in the morning
After a brief closure at noon
Bloom for the second time in the afternoon
Stamens mature
In these two blooming alternates the time is to happen at noon
In the middle of the day
In fact, the flowers on the tree will not bloom and closed together
There will always be sooner
Some are a little late
The alternate opening and closing phase will last one to two hours
Even three or four hours
This period of time
The species of flowers on the same tree are a bit confused
Provides an opportunity for pollination
But this is a case of relying on external conditions
Or a disorder of the flowering stage to pollinate
A fan of the more speculative kind
Thus fruiting in a low yield
The grower does not depend on this way to be pollinated
So it's only for families with fun
All right
The flowering theory of type a and type b is well understood
Now, I think we have another question
It's in you head
You must be talking
So much for your theory
What kind of breed belongs to type a after all
What kind of type b is it
Take it easy
Let's learn about avocado varieties and classifications now
Avocados are particularly abundant
Although you only have one or two varieties around you that are most familiar
But there are hundreds of species around the world
There are so many varieties
We can start with three lines
We'll wrap it up later with type a and b
These three strains
I've drawn up a table for comparison
It'll look a little more intuitive
According to the origin and characteristics of the fruit
Avocados can be roughly divided into three lines
The first is the Mexican system
The second is the Widimara system
The third is the West Indies
Of these three strains
The Mexican strain is the most hardy
It can withstand temperatures as low as minus six Celsius
Belonging to the cold-resistant type
The climatic conditions are similar to those of dried c citrus trees
The fruit trees of this strain are easier to distinguish
Its leaves are smaller
The biggest feature is to rub it with your hands
The leaves smell of fennel
They produce fruit with a thin, smooth skin
The pulp is thin
Seeds are larger
Usually a little early
In winter and spring
It blooms
Summer and autumn fruits will ripen
Between six and eight months from flowering to fruiting
Because of the cold resistance of the strain
Many fruit trees with avocados grafted on them
Both use the mexican variety as a rootstock
Like the bacon I grew, this species is Mexican
There is also the popular mexican west variety
There's Duke
Northrop and so on
The second strain, the Witima line
Cold Tolerance of the Widimara System
In these three strains belong to the middle
A little less than Mexico
Between minus 2 and minus 3 ℃
You're going to get frozen
This strain has bigger leaves
The young leaves will appear red or bronze
Rubbing with your hands will not give back the smell of fennel
Their fruit has a thick, rough skin
The seeds are smaller
Late bloomer
It blooms in late spring
In winter or early spring of the following year
The fruit will ripen
It takes about ten to fifteen months until the fruit ripens
Representative of the typical Vidal
The Malasi variety has
Hass is one of the most common ones in the supermarket
Hass
Gwen
It is also a common variety in many places
The third strain is the West Indian strain
The West Indian line had the worst cold tolerance among the three lines
It's usually freezing at about zero
So you can't plant it in a cold place
They have bigger leaves
The young leaves are pale green
Their fruit has a smooth skin
The seeds are larger
Some of the fruit is also very large
Some fruits are close to spherical
They bloom in spring and summer
The time from flowering to fruit ripening
It's shorter than Withermalasi
About six to eight months
The above is the introduction of the three strains
About another category
Which species are type A flowers
Which species are type B
I also summarized a table here
A friend who wants to plant and pollinate
You can look for what you need according to the varieties on the list
Of course, there are too many varieties
This list is just something I'm familiar with here
There are more familiar ones
I didn't list it anywhere else
There was no further study of those varieties
If you're interested
You can continue your research
After the last three seconds
You can save the screenshot
Are you ready
Three, two, one
Okay
For the sharing of avocado blossom and fruit
Do you understand
I hope people who have the same experience with me
can get the answer you want from it
Also hope to give the friend who has not planted but wants to try
Bring enough useful information
So you can avoid detours
