Om du vattnar varje kruka på morgonen, mår blommorna bättre i värmen.

Because Swedish uses verb-second word order in main clauses.

The sentence starts with the subordinate clause Om du vattnar varje kruka på morgonen. After that whole clause, the main clause begins, and in a Swedish main clause the finite verb usually comes first in the clause structure:

• Om du vattnar varje kruka på morgonen, mår blommorna bättre i värmen.

So the order is:

• subordinate clause first
• then verb
• then subject

This is very common in Swedish:

• Om det regnar, stannar vi hemma.
• När jag kommer hem, äter jag.

If the main clause came first, you would say:

• Blommorna mår bättre i värmen om du vattnar varje kruka på morgonen.

Both are grammatical, but the word order changes depending on what comes first.

Om means if in this sentence. It introduces a condition:

• Om du vattnar ... = If you water ...

It is a very common conjunction in Swedish for conditional sentences.

Compare:

• Om du kommer, blir jag glad. = If you come, I’ll be happy.
• Om det är varmt, öppnar vi fönstret. = If it’s warm, we open the window.

So here, om sets up the condition under which the flowers do better.

Vattnar is the present tense of vattna, which means to water.

So:

• att vattna = to water
• jag vattnar = I water / I am watering
• du vattnar = you water

In Swedish, the present tense is often used in general statements and conditions, just as in English:

• Om du vattnar ... = If you water ...

This sentence is giving a general rule or repeated situation, so the present tense is natural.

Varje kruka means each pot or every pot, while alla krukor means all the pots.

The difference is in emphasis:

• varje kruka focuses on the individual pots one by one
• alla krukor refers to the whole group collectively

So:

• vattnar varje kruka = water each pot
• vattnar alla krukor = water all the pots

Both could work depending on what you want to emphasize, but varje kruka highlights individual attention to each pot.

After varje (each/every), Swedish normally uses the singular indefinite form of the noun.

So:

• varje kruka = each pot
• not varje krukan

This is similar to English, where we say each pot, not each the pot.

More examples:

• varje dag = every day
• varje bok = every book
• varje elev = every student

So kruka is singular and indefinite because that is the normal pattern after varje.

Blommorna is the definite plural form of blomma:

• en blomma = a flower
• blommor = flowers
• blommorna = the flowers

It is definite because the sentence is talking about a specific set of flowers, namely the flowers in those pots. In English, we might simply say flowers in a general way, but Swedish often uses the definite form when the group is understood from the context.

So here blommorna means something like:

• the flowers
• the flowers we are talking about

Mår is the present tense of må, a verb often used for feeling or being well / doing well.

A very common expression is:

• må bra = feel well / be well
• må bättre = feel better / do better

So:

• blommorna mår bättre literally means the flowers feel better, but more naturally in English here it means the flowers do better or thrive better

Swedish uses må in situations where English might not always use feel literally. With plants, animals, and people, it can describe well-being or condition.

Using är bättre would sound less natural here, because må bättre is the idiomatic expression for improved condition.

Bättre is the comparative form of bra (good / well).

This is an irregular pattern:

• bra = good / well
• bättre = better
• bäst = best

So Swedish works like English here:

• good → better → best
• bra → bättre → bäst

That is why bättre is correct, not brare.

In the sentence:

• mår bättre = feel better / do better

I värmen means in the heat.

The noun is:

• en värme = a heat / warmth
• värmen = the heat / the warmth

Swedish often uses the definite form in expressions like this when referring to a general known condition, especially weather or surroundings. So i värmen is a natural way to say in the heat or in hot weather.

It does not necessarily mean one specific, sharply defined heat source. It is more like referring to the heat as an environmental condition.

Compare:

• i solen = in the sun
• i regnet = in the rain
• i kylan = in the cold

The usual Swedish expression is på morgonen, meaning in the morning.

This is an idiomatic time expression, and Swedish often uses the definite form in these cases:

• på morgonen = in the morning
• på kvällen = in the evening
• på natten = at night / during the night

So even though English does not say on the morning-the, Swedish naturally uses morgonen here.

Yes, absolutely. That would also be natural:

• Om du vattnar blommorna på morgonen, mår de bättre i värmen.

That version focuses directly on the flowers. The original sentence uses varje kruka to emphasize watering each individual pot. That may suggest careful, even watering, especially if the flowers are in separate pots.

So the difference is mostly about focus:

• vattnar blommorna = water the flowers
• vattnar varje kruka = water each pot

It can do both, depending on context.

In Swedish, the present tense is often used for:

• general truths
• habits
• future situations when the meaning is clear

So this sentence can mean something like:

• as a general rule, if you water each pot in the morning, the flowers do better in the heat
• if you do that in the future, the flowers will do better

This is very similar to English conditional sentences such as:

• If you water them in the morning, they do better in the heat.

The sentence has two parts:

1. Om du vattnar varje kruka på morgonen
   = a subordinate if-clause

2. mår blommorna bättre i värmen
   = the main clause

So the pattern is:

• If-clause + main clause

And because the if-clause comes first, the main clause shows inversion:

• mår blommorna
• not blommorna mår

A simple breakdown:

• Om = if
• du = you
• vattnar = water
• varje kruka = each pot
• på morgonen = in the morning
• mår = feel / do
• blommorna = the flowers
• bättre = better
• i värmen = in the heat

It can definitely be used for plants too.

Although må often refers to how a person feels, Swedish also uses it for animals and plants to describe how well they are doing or thriving.

So:

• Jag mår bättre. = I feel better.
• Hunden mår bra. = The dog is doing well.
• Blommorna mår bättre. = The flowers are doing better.

For a learner, it is useful to think of må bra / bättre as meaning be in good condition / do well, not only feel good in an emotional sense.
