Vi vil plante blomster i haven i foråret.

Vil is a modal verb. In this sentence, it can point to the future, so the sentence may be translated with will. But with a human subject like vi, vil often also suggests intention or willingness, so it can feel close to want to or intend to depending on context.

Danish does not have one single mandatory future tense the way learners sometimes expect. Very often, Danish uses the present tense for future meaning too.

After modal verbs such as vil, kan, skal, må, and bør, the next verb appears in the infinitive without at.

So:

• at plante = to plant
• vi vil plante = we will / want to plant

This is very similar to English will plant, where you also do not say will to plant.

Danish verbs do not change for person the way English sometimes does. You do not get different verb forms for I plant, we plant, they plant in the same way many other European languages do.

Also, because plante comes after the modal verb vil, it stays in the infinitive/base form:

• jeg vil plante
• vi vil plante
• de vil plante

The form of plante stays the same.

Because blomster here is an indefinite plural meaning flowers in a general sense, or some flowers.

Compare:

• blomster = flowers / some flowers
• blomsterne = the flowers
• nogle blomster = some flowers

English often also allows this kind of bare plural: We will plant flowers.

Because haven is the definite form of have.

• en have = a garden
• haven = the garden

Danish usually adds the definite article to the end of the noun instead of using a separate word like English the. That is a very common feature of Danish nouns.

For the same reason as haven: foråret is the definite form.

• et forår = a spring
• foråret = the spring

In the time expression i foråret, Danish normally uses the definite form. In practice, i foråret often means in the spring or this spring, depending on context.

This is a very common question.

• i foråret usually refers to a specific spring period, often this spring or in the spring
• om foråret usually means in springtime in a more general or habitual sense, often like every spring

So:

• Vi vil plante blomster i foråret = a specific plan
• Vi planter blomster om foråret = something we do in spring generally

Yes, it is the same preposition, and it is completely normal.

• i haven = in the garden → place
• i foråret = in the spring → time

Just like English uses in for both location and time, Danish uses i in both kinds of expressions.

The sentence follows normal Danish main-clause word order:

• Vi = subject
• vil = finite verb
• plante = infinitive/main verb
• blomster = object
• i haven = place
• i foråret = time

So the pattern is roughly:

Subject + finite verb + infinitive + object + adverbials

A very important rule in Danish is that the finite verb usually comes early in main clauses.

Yes, absolutely. That is a very natural Danish sentence.

When you move I foråret to the front for emphasis, the finite verb vil still has to stay in second position. That gives:

• I foråret vil vi plante blomster i haven.

This is a classic example of Danish V2 word order: whatever comes first, the finite verb stays in position two.

Yes. Danish often uses the present tense for future meaning when the time is already clear from context.

So:

• Vi vil plante blomster i haven i foråret = emphasizes intention/future
• Vi planter blomster i haven i foråret = also possible, with a planned-future meaning

Both can be correct. The version with vil can sound a bit more like a decision, intention, or prediction.
