Presadnicu metvice presadite u posudu s dobrom drenažom.

They come from the same root idea: presaditi, meaning to transplant / repot.

• presadnicu = the seedling / young plant being moved
• presadite = transplant! / repot! (an imperative verb form)

So the sentence is built around the idea of transplanting:

• presadnicu = the thing you transplant
• presadite = the command to do it

This kind of related noun + verb pairing is very common in Croatian.

Presadnica usually means a seedling, young plant, or transplant ready to be moved into another container or into the ground.

In this sentence, presadnicu metvice means a mint seedling or the mint plantlet.

The form presadnicu is not the dictionary form. The basic form is:

• presadnica = seedling

Here it changes to presadnicu because it is the direct object of the verb presadite.

Because it is in the accusative case, which is used for the direct object.

The verb presadite answers the question what should be transplanted?

• Presadite što? = What should you transplant?
• presadnicu

Since presadnica is a feminine noun ending in -a, its accusative singular usually changes like this:

• nominative: presadnica
• accusative: presadnicu

That is a very common pattern in Croatian.

Because metvice is in the genitive case.

The basic noun is:

• metvica = mint

In presadnicu metvice, the second noun describes what kind of seedling it is:

• presadnica čega? = seedling of what?
• metvice = of mint

So:

• presadnica metvice = mint seedling

This is a very common Croatian structure: one noun followed by another noun in the genitive to show relationship or type.

Because u can take different cases depending on meaning.

Here the sentence expresses movement into something:

• transplant it into a pot

When u means movement toward/into a place, Croatian uses the accusative:

• u posudu = into a pot/container

If it meant location, in a pot, then Croatian would use the locative:

• u posudi = in the pot

So the contrast is:

• staviti u posudu = put into a container
• biti u posudi = be in a container

Posudu is accusative singular of posuda.

• dictionary form: posuda = container, pot, vessel
• accusative singular: posudu

It is accusative because after presadite and u, the sentence expresses motion into the container:

• Presadite ... u posudu = Transplant ... into a container

So this is another example of the accusative being used for the goal/destination of movement.

It means with good drainage.

Here:

• s = with
• dobrom drenažom = instrumental case

After s meaning with, Croatian normally uses the instrumental.

So:

• dobra drenaža = good drainage
• s dobrom drenažom = with good drainage

This phrase describes the container:

• posudu s dobrom drenažom = a container/pot with good drainage

Because both the adjective and the noun must match in case, gender, and number.

The noun is:

• drenaža = drainage

After s, it goes into the instrumental singular:

• drenažom

The adjective dobra must agree with it:

• dobrom

So the pair becomes:

• s dobrom drenažom

This agreement is normal in Croatian: adjectives change to match the nouns they describe.

Presadite can be understood as:

• plural imperative: transplant (you all)!
• or formal singular imperative: transplant! when speaking politely to one person

In instructions, recipes, gardening guides, and manuals, Croatian often uses this form because it sounds natural and polite.

So in a practical text, presadite usually works like English instructional language:

• Transplant the mint seedling into a container with good drainage.

Croatian instructions often use the imperative directly because it is concise and natural.

So instead of saying:

• You should transplant...

Croatian often simply says:

• Presadite... = Transplant...

This is very common in:

• recipes
• care instructions
• manuals
• gardening advice

It is not necessarily rude; in this context it is just the normal instructional style.

Yes, posuda is a fairly general word meaning container, vessel, or pot.

In a gardening context, it can absolutely refer to a plant container or pot, especially when the context is already clear.

A more specific word would be:

• tegla = flower pot / plant pot

But posuda is still perfectly natural here, especially in more general care instructions.

The given word order is natural and neutral:

• Presadnicu metvice presadite u posudu s dobrom drenažom.

Croatian word order is more flexible than English because cases show grammatical roles. Still, not every version sounds equally natural.

For example, you could move parts around for emphasis, but the original is clear and standard for instructions.

A learner should treat the original order as the best default:

1. object
2. verb
3. destination
4. descriptive phrase

A useful breakdown is:

• Presadnicu — accusative singular
  direct object: the seedling
• metvice — genitive singular
  of mint
• presadite — imperative, formal singular or plural
  transplant!
• u posudu — accusative singular after u for motion
  into a container
• s dobrom drenažom — instrumental after s
  with good drainage

So the sentence shows several very common Croatian patterns in one short line:

• accusative for the object
• genitive for of X
• accusative after u for motion
• instrumental after s for with
