Among the many types of fruit trees, persimmons are believed to be particularly suitable as a home-grown fruit tree (family tree).
Although it is called “Momokuri 3 years, Kaki 8 years”, it rarely takes 8 years to actually plant modern cultivars and achieve results. However, it takes a long time to produce fruit, which is slower than other fruit trees.
The biggest reason why persimmons are still selected in growing home fruit trees, with the great advantage of eating quickly, is probably the “high fruiting rate”.
Although there are differences depending on the variety, even one bottle will bear fruit.
e? There is no pink this year, right? Will all of them fall even if they do?
Read this article to address all of these causes.
It is a graph showing the growth of a persimmon plant over a year. Let’s look at it somehow.
If you understand when and what work will produce a lot of delicious fruit and why you have to do it at that time, naturally you will understand the cause of the failure and the horticulture work will deepen.
Let’s check the work at each point in time while looking at the “cultivation schedule” of the persimmon.
Working from December to February[thời gian ngủ nghỉ]
The period of deciduous and inactive plants is called the “sleep period”. Depending on the variety and region, the hibernation period begins around November, but there are many important tasks that can only be performed during this period while the plant is resting. Be sure to complete it between the time the leaves fall and when they start to grow in March.
New persimmon planting work is also performed during this hibernation.
This is the beginning of our relationship with persimmons for decades to come.
Dig a square about 50 cm. Mix the compost, compost (taihi: leaf mold, cow manure, etc.) and bitter lime (kudosekai) with the excavated soil, then fill in half. For potted plants, use prepared soil. Spread the roots of the seedlings as wide as possible and plant them, while filling the soil tightly. Take care not to plant deeply and tie it to the rack to prevent it from falling. Water well so that the soil and the roots come in contact.
Avoid using chemical fertilizers when growing fruit trees. When using chemical fertilizers, it is necessary to calculate the details, analyze the soil, and determine the time of fertilizing strictly. Expect gentle fertilization effects with at least organic chemicals or fully organic fertilizers.
When using organic fertilizer 8-8-8 (the numbers represent the ratio of nitrogen, phosphorus and potassium), approximately 6 kg / plant. If the fertilizer composition is greater than 8-8-8, reduce the amount, but if the fertilizer component is smaller, increase the amount (mainly by nitrogen content, which is the first number).
It is the most important and skillful work in fruit growing, one that cannot be answered even in professional cultivation, but it is a profound and enjoyable one.
For domestic fruit trees, do not think wildly but think that it is the job of removing too crowded branches, not shining light. Because the leaves of the persimmon tree are large, there are branches that are quickly shaded. Leaves that are not exposed to light will die the following year. If you repeat this every year, you will end up with a persimmon tree as food for the crows, with no branches at the bottom and only fruit on the top and not harvestable.
In the following, we’ll explain important things to keep in mind when pruning persimmons, unlike other fruit trees.
This is an image of a pink branch.
Next spring, new shoots (shinsho: new branches to grow this year) will sprout from existing branches, and new shoots will flower. As for persimmon, only 2 to 4 buds at the tip of the branch have flowers.
All buds below have no flowers, only leaves. So, if you cut these important buds off, you won’t have any flowers or fruit next year.
There are many opinions that “when I ask the bonsai shop to prune, the tree will not bear fruit at all”, but the bonsai shop’s job is to shape the tree, in many cases pruning all the tips. That’s what happened.
Some people dare to cut to adjust the number of fruit, but for fruit trees in water, do not remove the tops but try pruning to pull out the branches crowded at the base and see through.
Working from March to July[Thời kỳ hoa / quả, thời kỳ phát triển chồi]
After the buds germinate, this time the plant’s body will flower, set fruit, elongate the branches and change rapidly.
Bud picking / fruit picking
The job of removing the buds before the flowers bloom is called “picking buds”, and releasing the mature fruit is called “picking the fruit”.
Fruit size and sweetness are caused by the photosynthesis of the leaves. One fruit is larger and sweeter than 4 branches with the same number of leaves.
Finally, 15 leaves per fruit, ideally 1 fruit per branch.
Also, as shown in the planting calendar, even with the same enlarged fruit, the number of cells itself is determined by cell division in the first half (May to July) and the number of cells. determinations are increased in the second half (August to November). Go.
In other words, the earlier you pick the fruit, the more fruit cells left on the branch, so you can expect better fruit, and the later, the less the number of cells at first even though the fruit then develops. how does it work? Therefore, the expansion efficiency is weak.
Physiological fruit loss
The most frequently asked question when planting persimmons is whether or not the fruit drop “falls off”. There are many people who say that they have trouble falling instead of picking fruit.
The main causes of fruit loss are as follows.
A characteristic of plants in general is the tendency to shed flowers and fruit when the tree tends to thrive. If you apply too much fertilizer or the young plant will fall off easily. Are there any fields or flower beds nearby? You may be smoking feces. Have you seen a lot of physiological (natural) fruit loss from June to July during the rainy season? If it is cloudy and not sunny enough, physiological fruit loss is likely to occur. If you don’t prune too much and it’s full of shade, you will get the same results. This is mainly caused by the food of Kakinohetamushiga (commonly known as Hetamushi) and ladybug. The most effective way to control these pests is to spray pesticides in June.
For domestic fruit trees, considering the possibility of fruit loss, wait until the end of June before picking fruit.
The risk of early physiological fruit loss at the end of June is much lower. If you make a mistake, don’t fertilize the summer earlier than this. The best time is early July.
During about a month in mid-summer from mid-July to mid-August, persimmons differentiate the next year’s flower buds on the tree. If during this period there are many fruits or not enough fertilization, watering will lead to a phenomenon of “every two years” in which the number of flowers and fruits will drop sharply next year to restore vitality. tree.
On the contrary, if there is no fruit or a lot of leaves are shed or physiological fruit loss, fertilizer should not be applied at this time. The situation got worse.
The amount of fertilizer is about 2 kg / tree for organic fertilizer 8-8-8.
Working from August to November[Thời kỳ thu hoạch quả to ra]
At this point, all you have to do in the persimmon plant is to protect the remaining persimmons.
Control pests and diseases
The main task in this stage is pest control. Especially ladybirds, which have been booming strongly in recent years, are very troublesome.
The main diseases are defoliation and tanso.
The most important time to spray is June. It will then be the end of August. It was also the time when the beetles and ladybirds flew back, the time when the pests were easy to penetrate, it rained a lot.
If you don’t miss two sprays of this chemical, productivity will increase dramatically.
Feces fall around early September do not worry about losing many physiological fruit.
From this point on, the balloon’s follicles should improve, especially thanks to the high potassium supplementation.
The amount of fertilizer is approximately 2 kg / plant with organic fertilizer number 8-8-8.
I wrote a bit of complicated content without hesitation so you can learn more about cultivation. I hope you enjoy it as a reading material.
If you treat each job with care and love, the tree will surely return it. As long as you put in effort, it will surely bring you a great taste of autumn.
