La mesa de cultivo incluye un semillero.

Because mesa is a feminine noun in Spanish, so it takes the feminine singular article la.

• la mesa = the table
• una mesa = a table

Grammatical gender in Spanish does not always match biological sex or make logical sense, so it simply has to be learned with the noun.

Literally, it means something like table of cultivation or growing table.

In natural English, this usually refers to a planting table, growing table, or a kind of raised planter. In Spanish, the structure noun + de + noun is very common for naming objects by their purpose or type.

So:

• mesa = table
• de cultivo = for cultivation / for growing plants

Together, mesa de cultivo works as one unit: a table or structure used for growing things.

Because in Spanish, after de, the second noun often appears without an article when it is describing the type, purpose, or category of the first noun.

So mesa de cultivo means cultivation table / growing table, not the cultivation’s table.

Compare:

• mesa de madera = wooden table
• gafas de sol = sunglasses
• tienda de ropa = clothes shop
• mesa de cultivo = growing table

If you said la mesa del cultivo, that would usually suggest the table of the crop/growing process, which is a different idea.

Incluye is the third-person singular present tense of incluir (to include).

It matches the subject la mesa de cultivo, which is singular.

So:

• La mesa de cultivo incluye... = The growing table includes...

Other forms of incluir:

• incluyo = I include
• incluyes = you include
• incluye = he/she/it includes
• incluimos = we include
• incluyen = they include

Here, incluye means it includes.

Because semillero is a thing, not a person.

In Spanish, the personal a is used before a specific person (or sometimes a pet/personified being) when that person is the direct object.

Examples:

• Veo a María. = I see María.
• Incluye un semillero. = It includes a seed tray/seedbed.

Since un semillero is an object, there is no personal a.

Because un means a/an, and it introduces one seedbed/seed tray as something included, not a specific previously known one.

• un semillero = a seed tray / a seedbed
• el semillero = the seed tray / the seedbed

Using un is natural if you are describing the features of a product or item for the first time.

A semillero is a place or container where seeds are sown so they can start growing. Depending on context, it can be translated as:

• seedbed
• seed tray
• seed starter
• nursery bed

It comes from semilla (seed) plus the suffix -ero, which often indicates a place or container associated with something.

So a semillero is literally something like a seed place/container.

Yes, mesa de cultivo is a normal term in Spain, especially in gardening contexts. It often refers to an elevated growing structure used for herbs, vegetables, or flowers.

In Spain, you may also hear related terms depending on the exact object:

• jardinera = planter
• huerto urbano = urban vegetable garden
• bancal elevado = raised bed

But mesa de cultivo is a standard and useful phrase.

Because Spanish usually links nouns with de when one noun describes the function, type, or relation of another noun.

So Spanish prefers:

• mesa de cultivo
• tienda de ropa
• zapatos de deporte

English often puts the describing noun first (growing table, clothes shop, sports shoes), but Spanish often uses de instead.

In standard Spanish from Spain, incluye is pronounced roughly like een-KLOO-yeh.

A few helpful points:

• It has three syllables: in-clu-ye
• The stress falls on clu
• The y in ye sounds like the y in yes, though pronunciation can vary slightly by region

So: in-CLU-ye

Yes, sometimes, but the meaning shifts slightly.

• incluye = includes
• contiene = contains

For a product description, incluye often sounds better if you mean that something comes as part of the item or package.

Examples:

• La mesa de cultivo incluye un semillero. = The growing table includes a seed tray.
• La caja contiene semillas. = The box contains seeds.

So incluye is a very natural choice here.

Yes. De cultivo can be used with other nouns to show a connection with growing or cultivation.

For example:

• tierra de cultivo = farmland / cultivated land
• bandeja de cultivo = growing tray
• técnicas de cultivo = cultivation techniques

In mesa de cultivo, it tells you what kind of mesa it is: one used for cultivating plants.

Yes, the sentence is in the present tense:

• La mesa de cultivo incluye un semillero. = The growing table includes a seed tray.

A simple past version could be:

• La mesa de cultivo incluía un semillero. = The growing table used to include / included a seed tray.
• La mesa de cultivo incluyó un semillero. = The growing table included a seed tray.

The best past tense depends on context, but the original sentence is a straightforward present-tense description.
