Chapter 26 Changing Basins

According to Professor Slughorn's performance just now, the plan to borrow plant seeds from Slytherin can almost be abandoned, and Pomona began to rejoice that she went to the Forbidden Forest, at least Wilmina knew that someone needed her, Maybe after reading those patients, she will suddenly remember that there is another student in her college who needs her help.

The dean's office is usually near the college lounge, but Pomona handed over the job of opening the door to Hagrid. The reason why professors are called professors is that in addition to teaching, they will also conduct research in their respective fields of expertise. In order to avoid being disturbed or someone stealing their research results, they will set up a ban in their office. A giant, even a half-giant, has stronger resistance to magic than an eleven-year-old child.

"Okay." After opening the door, Hagrid's hair stood on end. "Go in, you two little fellows."

"Thank you." Pomona ran in first, wiping Hagrid's stomach.

"Thank you." Lupine also said as he passed by Hagrid, and then he waved his wand and said "Luminescence", and the scene in the office appeared in front of the three of them.

Behind the empty desk was a copper plate engraved with Hufflepuff's hundred codes of conduct, the first being to keep a low profile, and the hundredth was "Low profile because you can always be high profile".

"Lupine, we're going to dig out the soil from under the willows and replace the whooping willows from the bottom up."

"You say I'm crazy, but you're actually crazy." Lupine said, tongue-tied for a long time, "Do you know how much work it takes?"

"You said you once read your mother's potting books, how much do you know about the changes in the root system during plant growth?"

Lupine was silent, and Hagrid raised his hand eagerly at the door.

"The rooting of plants is divided into vertical roots and horizontal roots. There are also big trees growing on cliffs with barren land. Its backbone roots can penetrate deep into the cracks in the core soil and rocks to take root. The horizontal root system is the opposite, mainly affecting flowering and fruiting. When the downward transportation of saplings is blocked, or when the above-ground part declines sharply for various reasons, the horizontal roots are the first to suffer the most, and then the vertical roots. When the adult trees are blocked in the underground transportation, they will be threatened sooner. The most important thing is the vertical root. The clay soil has poor water permeability, neither drought-resistant nor waterlogging-resistant. The root system is not easy to extend, but it has strong water retention and fertility, and nutrients are not easy to leaching. It is precisely because of the fertility in the soil that Professor McGonagall and the others use it. Birth magic turns a sapling into a big tree. After the soil fertility is exhausted, if the vertical roots cannot penetrate the soil and continue to grow, the horizontal roots will become vertical roots. It is the horizontal roots that are trying to tear down the wall today. If the vertical roots are not freed Roots, they will continue to try to tear down the wall and turn them into vertical roots. Whomping willow is not a mandrake after all, we can't uproot it and put it in another pot with loam prepared in advance, so we can only The soil was changed from below to above without damaging its vertical underground roots as much as possible."

"Then why did you look for Wolfsbane in the first place?" Lupine asked.

"I was wrong. I was only thinking about changing the soil properties, and I forgot that the Whomping Willow also needs nutrients during the growth process. Now it doesn't have enough nutrients of its own. If there are other plants competing with it for nutrients, it will be even worse. Furious, clay and sand are combined in a certain proportion to become loam, and now the underground soil has either been deserted or hardened, and the Whomping Willow is so violent because it threatens its life."

"What do we need?"

"Collect carbon slag and stones, and things like fruit peels and egg shells."

"There are peels and eggshells in the kitchen," said Hagrid excitedly, finally finding his chance to speak.

"In addition to changing the soil, we also need to fertilize the willow. The fertilizer must be fully fermented before it can be mixed into the soil. Otherwise, the temperature generated during the decomposition of the fertilizer will burn the roots to death. The process of fertilizing will smell bad, you know. Where can I get fat without affecting other people, Hagrid?"

"The forest farm is fine."

"It's too far away." Pomona shook her head, "Forget it, you guys go and prepare what I just said."

"Okay, Professor." Hagrid said naturally, "Do you need me to call Professor McGonagall?"

"Not for now." Pomona took out the "How to Care for Whomping Willow" "We are going to dig a tunnel under the tree. If you know any magical creatures in the Forbidden Forest that are good at digging holes Even better, move faster, the potion can last until midnight at most, I don't know when it will wake up!"

"Let's go, Remus, Pomona knows what she's doing, and we'll meet at the Whomping Willow later."

Remus Lupine gave her a thoughtful look, and finally left with Hagrid.

Pomona still kept smiling on the surface, and she didn't restrain her smile until they were all gone.

Judging from the performance of the centaurs before, it was impossible to dig that tunnel into the Forbidden Forest. As long as Lupine entered their territory, he was very likely to be attacked. Now the only choice is Hogsmeade.

If a werewolf were to get out of hand in a village, goodness knows what chaos it would cause.

She wanted to find a place for Lupine where he could transform without worrying about him running away, preferably outside the village, but where exactly?

"Is anyone there? Professor, are you back?" Pomona was thinking, when she heard Pete's voice.

"Peter!" She threw herself into his arms as if seeing a savior.

"Pomona, why are you?" Pete was more surprised than she was. "What are you doing in Professor Graplan's office?"

For an eleven-year-old, the first day of school was so exciting, it could even be said that it was too exciting. Pomona cried while holding Pete, and she almost cried like the other first graders. Ready to go home.

"Have you been bullied? Tell me, and I'll teach him a lesson!" Pete said confidently.

"I'm afraid you can't beat him," Pomona twitched.

"Who?" Pete looked as if Pomona would kill Avada by saying that name.

"Professor Dumbledore." She paused and said, "And Professor Slughorn of Slytherin. I met him in the corridor just now, and he deducted two points from me."

"Aren't you going to tell him you're lost?" Pete pointed to Hufflepuff's rules on the wall. "What's number two?"

Fight back in the face of direct insults, but play dumb when necessary.

Pomona wouldn't be stupid enough to read it out and say instead, "They say I'm being bullied, do you think he'll let me go if I tell him that?"

"Damn Slytherin." Pete gritted his teeth in hatred. "Let's see."

Pomona tugged on Rapide's sleeve.

"what happened again?"

"I have a little favor I want to ask you to help."

"What are you going to do again?"

"It's nothing, just repotting a plant." She smiled sweetly and said, "Can you call all your friends?"
