What is the cause of radish sprouting, overeating, and waterlogging?

Twenty days old radish 21

No buds coming out.

It is a successfully sown turnip seed, but there are some growers who do not release new seeds except for some shoots.

One of the two people sowed the seeds. There were almost no buds

After sowing and watering, there is nothing you can do after that. It feels like drawing, whether it sprout or not. And I think this time’s Omikuji was written like this.

“There are no waiting people, people to stop.”

To find out the cause, we will issue SOS to Mr. Souya Hashiguchi, who is familiar with “Soyan Master”.

What is the cause of not sprouting?

What happened to this sowing? Let’s review the process and find the mistakes.

Is there a problem with the soil?

First, I put the soil in the potted plant. You cannot make mistakes here.

I used two types of soil.

ARecycled land Used when growing cucumbers in the summer (sun-sanitized)

Made from palm fiber so it feels soft and light.

BNew cultural landI just bought it at the center.

Did you sow bad seeds?

When the potting medium has been filled with soil, a trench is created on the surface of the soil and seeded. Period is good. Hmmm, is this wrong?

There is also a fact book that says, “Seeds are sown 1 cm apart”, but they have been properly packed.

Kikuchi

When sowing seeds, I wrap them up instead of 1 cm apart. Is it because it’s too crowded to sprout?
If this happens, you should be fine if you lose weight early.

Soyan

The timing of sowing is clearly safe.

Is there too much land?

After sowing the seed, I covered it with soil. The covered soil is about 2 cm. Newly transplanted soil (B), not yet sprouted, after watering, it feels like the soil surface is seized. Recycled soil (A) germinates immediately, so I’m worried that (B) cannot sprout due to soil resistance.

Kikuchi

Did you cover the soil too thick?
I think 2 cm is just right for a turnip. However, if the soil is compact, you will most likely run out of oxygen. If the seed cannot breathe, it will not sprout.

Soyan

I’m not sure if this happened outside or safe, but I do find that “air” is also an important factor.

After all, this is the cause?

After sowing the seeds, I watered a lot of water. “Water” is important for germination

After covering the soil, I lightly press the surface and water a lot of water. Planters are placed on a thick wall on the veranda.

Kikuchi

When watering, there is a feeling of standing water on the surface and not penetrating inside. This is not good, right?
I agree. Like a newly unloaded towel can repel water, soil can repel water. Seeds germinate when they contain water, but they will die if there is not enough water before they take root.

Soyan

Kikuchi

I didn’t even water it, and it was a shame.
When sowing in the planting platform, after sowing, water fully, then put in a shady place so that there is no watering until germination, or cover with newspaper to prevent the soil from drying out.

Soyan

Kikuchi

Don’t water until the seeds sprout? ?? Not knowing that, I dried it in the sun …

A, out ~. Since I am a sun supreme these days, I have no idea to put it in the shade.

It is also important that the soil temperature is appropriate, says Master Soyan. It seems that the three “water”, “air” and “temperature” conditions are very important for seed germination.

After learning a bit about the possible causes, I decided to do it again.

Check for differences in water permeability of each soil type

I noticed something was wrong with the soil when I accidentally dug up the soil to sow it again.

The soil on the surface (right) is wet, but the soil dug up (left) is dry.

The surface of the soil was wet with water, but the soil dug up was dry and dry. It seems that some of the parts are waterproof, but most of them are still waterproof. How. This will not reach seeds with enough water.

Certainly, I was worried that water would form on the surface. So I put each of the five soils on the porch into a plastic cup and poured an equal amount of water down from the top to check the permeability.

ALike the land of Planter A, used again from the previous crop.
Light soil made of palm fiber and fine shavings.
BIt resembles Planter B, and I just bought it.
An integrated cultured soil created by adding peat moss and vermiculite to Akatama and Kanuma soils.
CThe raw materials are palm fibers and the bark has been broken down. It’s dark and moist.
DFrench fries and rice husk charcoal mixed with palm fiber. It is wet.
EIt is made from large and small pieces such as coal and vermiculite. The feeling of fluttering.

The results are self explanatory.

From the side of the plastic cup containing the uncovered soil (B), I can clearly see where the water is soaked and what is still dry. It stays that way even after a while until it penetrates.

Some parts are immersed in water and some are not.

Of course, the conditions are different from when you put it in a large pot, but it’s possible that the water seeped in the same way.

By the way, something surprising happened with the cucumber’s recycled soil (A) cup. The water was completely drained and collected on the bottom of the cup.

Water passes through the soil and only water collects at the bottom

With this, the water retention effect cannot be expected. The reason why trees are sprouting on this land is probably due to proper watering. When I mix it with water by hand, I feel that the filament is absorbing water and expands. It looks like you need to take a little care as it dries.

The remaining soils (C) and (D) also contain palm fibers, but they feel damp and moist from the state they were in the bag, and they immediately soak in when watered. (E) is soil that appears to be made up of large and small particle fragments, and I feel no problems with penetration.

Just looking at this result, it is impossible to say unconditionally good or bad soil. However, I understand that knowing the properties of each soil type has the potential to minimize failures.

What is the cause of the slowdown?

On the other hand, regenerated soil (A) that has sprouted but has become longer than necessary is called an elongated state. Why.

According to Master Soyan, there are 4 possible reasons for the leader.

Due to the lack of sunlight this year, our seedlings are also slightly shrunk.

Soyan

Kikuchi

Right! Can’t be helped if it’s a weather problem.
However, in Mr. Kikuchi’s case, the amount of soil is small and it can be difficult to get the sun. Same with cucumbers.

Soyan

Kikuchi

Well, the same failure! I thought I couldn’t make a mistake but made a mistake right from the first filling …

There is a surface of soil below the line “Put land so far”

When I checked the amount of soil from the teacher’s point of view, it was definitely small. I intend to put the soil under the line “Put the soil far away” inside the potted plant, but the surface of the soil I actually see lies below that line.

In addition to making a conservative estimate when considering seeding, it is possible that the soil subsided slightly due to watering. It is like a beginner cooking with a modest amount of salt.

In addition, it can be said that (4) thinning should be done earlier and more fully.

The long-awaited germination

Water well before sowing, so that the soil is soaked with water.

The soil of (B) that did not germinate was first moistened, then re-seeded, covered with soil and watered again from above.

Three days after sowing again, a portion of the soil germinated. Then wait a few more days, the young shoots gradually grow. However, it seems that the appearance of the shoots is still not uniform.

Some have all buds and some have almost no buds.

There seems to be a special soil for sowing, so this may not be suitable for sowing. In addition, it is compatible with each vegetable. Even so, there is a lot of wisdom and tips to learn from sowing a seed.

The path of sowing was not completed in a day.
Turnip cultivation was not completed in 20 days.

The path to a vegetable garden, where vegetables grow in abundance, seems as far away as Rome.

◆ Take one step and take two steps down. Next time, we will plant seeds that utilize the properties of the companion plant.
