Questions & Answers about huànpén yǐhòu, gēnbù zài yíngyǎngtǔ lǐ.

Why is 以后 placed after 换盆? Does 换盆以后 mean after changing the pot / after repotting?

Yes. 以后 means after; later; following, and it often comes after a time word or an action phrase.

So:

• 换盆 = to change the pot / to repot
• 换盆以后 = after repotting

This pattern is very common:

• 吃饭以后 = after eating
• 下课以后 = after class
• 回家以后 = after going home / after returning home

So in this sentence, 换盆以后 sets the time frame: after repotting.

Why is there no subject in the sentence? Who or what is being repotted?

Chinese often omits the subject when it is obvious from context.

In a fuller sentence, you might have something like:

• 植物换盆以后，根部在营养土里。
• After the plant is repotted, the roots are in the potting soil.

But if the topic is already clear, Chinese commonly leaves it out. This is very natural.
So the sentence is not incomplete—it just relies on context more than English usually does.

What exactly does 根部 mean? Is it just root, or something more specific?
