枯れた枝と生きた枝の見分け方！原因と対策【盆栽Q】

I'll show you how to tell if a branch is dead or not. This one is already dead. And it's not wet. The leaves are still there, but this one is dead. But it's still alive. It's alive, but it will die later. I see. What do you mean by it's still alive? Well, I'll try to cut it. I'll try to cut it. It's a little... You can see it better with naked eyes. It's still wet. I see. It's still wet. Yes. This one is not wet. You can tell by the color. It's not wet. You can tell by the color. I hope you can tell. I hope you can tell by the video. This one is still alive. It's a little white. I can tell by the powder. It's a little white and brown. The reason why the leaves fell off first is because the water didn't go through. The leaves are still green and weak. That's why the leaves fell off first. But not only this. Other trees are also alive even if the leaves fall off. They are still alive. If you look at the tip of the tree, you can see that the leaves are not wet. I don't usually do this. If you think it's dead, you can cut it from above. It may be hard to see in the video. This branch is still wet. For example, I cut this part. This part is not wet. You can judge whether it is alive or not by judging the cut part. I gradually cut it to the back. If it's still alive, leave it as it is. It's completely dead like this. It's a little brownish and not wet. It looks like it's dead. The skin of the tree is dead. You can cut it from the beginning. If it's hard to judge, you can check from the tip. You can judge whether it is alive or dead. What is the cause of the death of this branch? The weak eyes. The strong sunlight in summer. There are various causes. I can't narrow it down to one cause. If it's a healthy tree, it's no problem. This tree is 70 to 80 years old. It may be older than that. It's getting weaker as I get older. It's different from when I was in my teens and twenties. The weaker the branch, the more it withers. Can't it revive? This branch can't revive. It will wither eventually. What if it's a little earlier? There is a place called Dobukime in this area. If you wipe it here, it will regrow. Or if a young branch comes out, you can put a branch here before it withers. There is such a method. You taught me. There is such a method. However, if it is an old tree, it is difficult for a new young branch to grow. And it doesn't grow. It's hard. The more it gets older, the more it will wither. When you prune this branch, insert it and make a child of it. I see. If the child has grown to some extent, you can call it here. I see. It's an older tree than this. You can call it here. I will put this branch here. If it is not a branch of this tree, it will wither if it is a branch of a different tree. Insert your own branch and put it in a place where there is no branch. For example, there is no branch here. It's a call. That's right. Is this a call? That's right. It is a call of this branch. Why is it a call up here? It's just near here. This is it. That's right. It's a call. That's right. From here. This branch is brought here. You fix the branch that you inserted and extended here and call it. This is more reliable. That's right. It's a call. It's deep. It's been more than 100 years. It's great. If the branch inside does not catch fire, it will weaken. There is a risk of withering. It takes many years to regenerate. It's a craftsman's skill. How do you distinguish a withered tree? First, look at the tip and see if there is water. Cut it to the point where there is water. If there is water, stop there. Wait for a while and look at it again. If you wait until next spring, you can see the result. If you don't see it in spring, it's withered. You have no choice but to accept it. That's right. Cherry blossoms and cherry blossoms wither quickly. There are no leaves here. This is alive. As you can see in this video, this is brown. That's right. Normally, it's green. The green part is alive, but the brown part is withered. Is there anything to prevent withering? I think there are various things. First of all, water. Water. Avoid strong sunlight in summer. If you look at the branches in the back, the upper branches get in the way. They don't let the sun in. It makes the tree weak. So, let the leaves pass through a little. Let the sun pass through to the inside. Also, think about the wind. If the wind doesn't pass through, the branches will get wet. Also, diseases, insects, and fertilizer. There are various things. Don't be afraid of withering. It's good to gain experience. That's right. You have to think about the cause of withering. The main cause of withering is water. Water. That's right. It's a one-shot thing. Water alone is life. Water is life. Humans live without water. That's right. Even if there is no food, it's okay. But if there is no water, it's no good. In a few days. Thank you very much.
