⑦ How to plant a lemon in pots

👉 Proper time for plantation

Proper time to plant the young plant of

the lemon is from the end of February to

the end of March as same as a garden


In the case of a potted plant, we can

carry a bowl to the room without

influence of the cold at cold winter


Therefore you may plant it from September

to October.

👉 A large seedling is suitable

  for a potted plant

A large seedling is suitable for a potted

plant. This is because the large seedling

can be grown as the bowl which it

purchased, and the first fruition is

earlier than a stick seedling.

When we choose the large seedling, we

should choose a young plant which is

branching off equally from the plant

foot treatment.

Because the space where fruits grow

increases and can finish it compactly.

👉 Various bowls

We are divided into a plastic bowl, an

unglazed bowl, an earthenware bowl by

the difference in materials. There is the

light, strong resin bowl. You should

better to buy a light plastic bowl and

resin bowl, because you may carry it to

the room at the winter cold time.

As a matter of course, the weight of the

young plant and soil will be added to

weight of bowl itself.

An oblong bowl has a sense of stability

than a tall bowl. If there is a bowl that

the diameter of the bowl top is same as

a bowl bottom, it has a sense of

stability more.

The design is important, too. But,we will

image height and width of the future

young plant. I recommend that you choose

the bowl which "is hard to fall down".

👉 Soil to use

A weed is easy to grow when we use the

garden soil, and also, the drainage is

not so good, too. The "soil for fruit

tree" seems to be good if available.

The acidity of this soil is ph5 .5-6.0,

and you can just use it.

When it is not available, you mix

"the soil for vegetables" and Kanuma

soil in the ratio of 7:3 and seem to

use it.

👉 Plantation methods

As for the plantation method, please see

the next article "transplanted a potted

lemon". In addition, even in the case of

a potted plant, we can suppress the

growth of the tree. For example,

we pull a branch aside. we suppress the

growth by doing this way and can make

with fruit better. At first we roll the

edge of the bowl with a string.

Then, we tie the string which I wrapped

the edge in the branch which I want to

pull aside with a string.

⑧ How to transplant a lemon

strong>into a bowl

In the case of a potted plant, the inside

of the bowl becomes full of roots when we

just leave it. So, it is usually

necessary to transplant it at the pace

once in 2-3 years. The old root comes to

wither up to become hard to suck water

well even if we do watering.

① A root comes out of the bottom

of the bowl

② Water did not readily soak into soil

  even if we did water

While being careful about such states, we

transplant it into a slightly big bowl. (

1~2号 larger ) By the way, we can

measure the size (号) of the bowl when

we divide a diameter by 3㎝. (30cm in

diameter /3cm = 10号) Even if you do not

want to make a bowl big, please

transplant it, and please cut down a

jam-packed root.

When we transplant it, we warn next.

A root may rot when we transplant a

seedling into a bigger bowl suddenly

because soil does not readily dry. T

herefore you seem to be careful about

the size of the bowl to exchange.(into a

slightly big bowl)

By the way, I did not know the above.

Therefore I have exchanged it with a 14号

bowl from a 7号 bowl when I

transplanted the potted lemon which I

purchased. At hot time of July, I did a

good watering every day twice in morning,

an evening. I do not seem to do the

decayed root for the moment. I want to

be careful about decayed root in future.

⑨ Care for flower and bud

  (I work on pollination)

👉 About pollination

As the young plant of the lemon is

pollinated with one and bears fruit,

the pollination tree is not necessary.

In addition, we do not need the

artificial pollination basically because

the insects carry the pollen. My lemon

does nothing in particular, but it is

pollinated and bear fruit.

(There is not particularly a lot an


But it seems to become hard to be

pollinated when insects do not come very

much. When a fruit does not grow

though the flower of the lemon blooms,

please do artificial pollination. A fruit

seems to have possibilities to grow.

The artificial pollination is possible by

using dry writing brushes when we touch

it in turn in a stamen and the pistil


👉 Care for flower and bud

We pick all the flower (bud) which

bloomed in autumn and summer to promote

that we grow fruit.

(When we grow the fruit which grow from

the flower which bloomed in spring)

About the flower(bud) which bloomed

 in spring

When do you pick a bud and a flower? 

A judgment seems to change by a purpose.

a.A leaf is necessary to grow fruit.

e="font-size:16px;"> (20 pieces of leaves are necessary

  for one fruit?)

b.If we pick the bud and flowers,we can

  spend the nourishment for branches

  and leaves and flowers and buds

  which we left.

 ⇒We should pick flowers and buds.

c.In consideration of a physical fruit

  drop, we do not pick flowers and


 ⇒We should not pick flowers and buds. 

Physiological fruit drop (June drop)

We seem to be able to consider that a

physiological fruit drop is a self-regulating

function of fruit tree itself. A physiological

fruit drop is a menstruation phenomenon

that it try to leave a few fruits which

is only grow and drop other fruit when

nutrition is insufficient.

A menstruation phenomenon. When there are too few fruits drop, a tree body weakens and causes a biennial bearing. (A high yielding year and low yielding year came one after the other.) On the contrary, when there are too many fruits drop, growth becomes popular, and the branch will be a abnormally long branch. The physiological fruit drop is classified roughly into two ways. One is an fruit drop appearing soon after the flowering. It is a latter term fruit drop appearing before a crop one more.

We can concentrate on giving nourishment to a bud and flower and the branches and leaves which we want to leave when we pick up an unnecessary bud and flower. However, when a fruit has begun to become really, physiological fruit drop happens, and a fruit hardly remains if "a fruit to bring up" falls. Therefore we do not cut a bud and the flower and leave all. A way of thinking to perform fruit picking after a physiological fruit drop is like C.

This year my garden planted lemon has added about 100 flowers. It was a bud for a long time, but the flowers finally bloomed. However, when I thought that the flowers bloomed on May 10, the flowers began to fall on May 13. If you would like to organize to a certain extent in advance, I think that it would be better to do a bud picking rather than a flower picking.

In lemon flowers, incomplete flowers without stamen may bloom. (Of course, it does not become a fruit.) It is said that low temperature is the cause. Also, if the tree is still young and there is no power to fruit it seems there will be many incomplete flowers. Lisbon lemon raised in our house seems to be a species with many incomplete flowers. Meyer lemon is a kind that fruits are often attached, and it seems that there are not too many incomplete flowers. If incomplete flowers bloom, it would be better if you picked flowers. (After scattering naturally, remove residual flowers.)

The record at that time is here!

「Finally blooming flowers!」

👉 I tried picking fruits of lemon of potted plants.

      The state at that time is "here"!

⑩ Cutting of the lemon

It cuts out the branches, stems, leaves etc of the plant, inserts it in the soil and puts out the roots. Fresh branches at the tip of the branch and flexible branches under extension seems to be unusable for cutting because it tends to rot after insertion. Branches that have stopped growing and become a little harder seem to be suitable for cutting of lemons.

As a suitable period, it is said that the period of the rainy season in June is good. Cuttings are said to be less prone to fruit, less vulnerable to diseases and pests, shorter life span than grafts. However, it does not need to prepare a rootstock, and the point that it is relatively easy to increase seedlings is attractive.

It is said that citrus fruits are relatively easy to cut. When I cut it, for example, I used a "root promoter", but it is said that roots grow only by adding nothing at all "just put the cut branches in soil".

① cutting branches that have stopped growing and become a little harder, ② growing in a shade not exposed to rain, ③ watering every morning and evening, etc. are the points in cutting. However, I think that "roots will grow on cuttings just by watering firmly everyday."

On June 17, I cut seven branches. I raised it in the shade that does not hit the rain.(One of them raised in the place where sun and rain hit) A new sprout came out from one branch after 42 days. After that, sprouts came out from all the branches.

<Cutting procedure I did>

a.Cut the solid branches into a length of 10 to 15 cm.

      And drop the leaves on the lower half of the branches.

      Next, cut the remaining leaves in half.

      (To suppress transpiration)

b.Soak this branch in a bucket filled with water.

      (About 1 hour)

c.Cut the lowe
r tip of the branch off the water diagonally.

      (To increase the cross sectional area and increase the water supply volume,

      and to expand the area where the roots come out.)

d.Apply a rooting promoter to the lower tip of the cut branch.

e.Put the soil exclusively for sowing buds and seeds, and insert the cuttings.

      When inserting, digging the hole, cover the branch with soil

      so that rooting promoter can not be removed.

f.Add water to the whole.

Here is the situation when I went cutting.(With photos)

「I tried cutting with lemon!」

Since the roots came out from the cuttings, the state at the time of replanting into a pot is here.

 「Cutting of lemon 54 days later ...」

In the future, seedlings made of cuttings,

① Is it difficult to become fruitful? ,

② Is it vulnerable to diseases and pests? ,

③ Is the lifetime short? ,

I would like to validate.

⑪ Grafting of lemon

Looking at the lemon seedlings that are on sale, most of them seem to be seedlings made from grafting. Grafting is done because cold resistance and disease resistance will be higher than without grafting. That is because you use a growing stock. 

Depending on the type of fruit trees and flowers, there are things that can not be seeded, or it takes a long time to be able to grow, when raised from their own seeds or when raised with cuttings. When growing with grafting, it will be fruit soon, it seems that you can make a strong tree against diseases and pests. 

"Karatachi" often used as a rootstock of lemon

It is a characteristic that there is a big thorns, and fruits is a cold-resistant variety among the citrus. It is also known as the bait of swallowtail butterfly. It can be used as a rootstock of all citrus fruits. Karatachi is used as a rootstock in 95% of domestic citrus fruits.

When raising "Karatachi" as a rootstock from seeds, it seems necessary for about two years. In addition, when purchasing seedlings of Karatachi, a sending fee (around 1,000 yen) will be required for 1 seedling (around 600 yen) . If so, rather than trying grafting, it will be cheaper to purchase lemon seedlings.
