Im Beet wächst schon wieder Unkraut, also ziehe ich es nach dem Frühstück heraus.

German often puts the element it wants to emphasize in the first position. Here, Im Beet sets the scene first: In the flowerbed / garden bed.

The normal declarative rule is still that the finite verb comes second, so after Im Beet, we get wächst:

• Im Beet wächst schon wieder Unkraut.

You could also say:

• Schon wieder wächst im Beet Unkraut.
• Unkraut wächst schon wieder im Beet.

All of these are possible, but they put the focus in slightly different places.

Im is simply the contraction of in dem:

• in dem → im

German very often contracts certain preposition + article combinations. So:

• im Beet = in dem Beet

This is completely normal and usually preferred in everyday German.

Here, das Beet means a garden bed, flowerbed, or vegetable patch—a planted area in a garden.

It does not mean a sleeping bed. That word is das Bett.

So:

• das Beet = garden bed
• das Bett = bed to sleep in

That one-letter difference is very important.

Unkraut is often used as an uncountable or mass noun, similar to words like water or grass in English.

So German commonly says:

• Unkraut wächst = weeds are growing / weed is growing

without an article, because it is talking about weed growth in a general sense, not about one specific weed.

You could use an article in other contexts, but here the article-less form is the most natural.

Because Unkraut is grammatically singular.

Even though English often uses weeds in the plural, German frequently uses Unkraut as a singular mass noun. So the verb agrees with that singular noun:

• Unkraut wächst = singular
• Die Unkräuter wachsen = plural, but this is much less common in everyday usage

So the sentence treats Unkraut as one general substance/category, not as several separate plants.

Schon wieder means again already, or more naturally in English, yet again, again, or once again.

It often carries a tone of mild annoyance or frustration:

• Im Beet wächst schon wieder Unkraut. = There are weeds growing in the bed again already / yet again.

So it suggests this is something that keeps happening.

Because in German, the finite verb still has to stay in the second position in a main clause.

Here, also means so or therefore and takes the first position. That means the verb comes immediately after it:

• also ziehe ich es heraus

Structure:

• position 1: also
• position 2: ziehe
• then: ich

This is similar to words like deshalb, darum, or dann.

Compare:

• Ich bin müde, deshalb gehe ich ins Bett.
• Es regnet, also bleibe ich zu Hause.

This is the separable verb herausziehen, which means to pull out.

In a main clause, separable verbs split:

• Ich ziehe das Unkraut heraus.

So:

• ziehe = the main verb part
• heraus = the separable prefix, which goes to the end

That is why the sentence says:

• also ziehe ich es nach dem Frühstück heraus

In the infinitive, the two parts stay together:

• das Unkraut herausziehen

Because das Unkraut is a neuter noun, and the matching pronoun is es.

So:

• das Beet → es
• das Unkraut → es

In this sentence, es refers back to Unkraut:

• ... ziehe ich es heraus = ... I pull it out

Also, es is in the accusative case here because it is the direct object of ziehen.

The preposition nach takes the dative case when it means after in a time expression.

So:

• das Frühstück → dative dem Frühstück
• nach dem Frühstück = after breakfast

This is a very common pattern:

• nach der Arbeit = after work
• nach dem Essen = after the meal
• nach dem Unterricht = after class

Because heraus is the separable prefix of the verb herausziehen, and in a main clause it normally goes at the very end.

So the sentence is organized like this:

• also ziehe ich es nach dem Frühstück heraus

You can think of the core structure as:

• ich ziehe es heraus

and then the time phrase nach dem Frühstück is inserted before the final separable prefix.

That final position for the prefix is very typical in German main clauses.

Yes. Rausziehen is the more colloquial spoken form of herausziehen.

So you might hear:

• ... also ziehe ich es nach dem Frühstück raus.

That sounds more conversational.
Herausziehen sounds a bit more neutral or standard-written.

Both are correct; the difference is mostly register and style.

You usually need herausziehen here if you want the idea of pulling out clearly.

• ziehen by itself just means to pull
• herausziehen means to pull out

Since the point is removing the weed from the soil, herausziehen is the natural choice.

Other possible verbs in similar contexts include:

• ausreißen = to rip/pull out
• jäten = to weed

But herausziehen is very straightforward and easy to understand.
