Demain, nous allons planter des graines dans deux grands pots le long de l’allée.

Yes. Demain means tomorrow.

French often puts a time word at the beginning of a sentence to set the scene:

• Demain, nous allons planter... = Tomorrow, we’re going to plant...

You could also put it later:

• Nous allons planter des graines demain...

Both are correct. Starting with Demain just gives it emphasis.

Nous allons planter is the near future in French, formed with:

• aller in the present tense + infinitive

So here:

• nous allons = we are going
• planter = to plant

Together, nous allons planter means we are going to plant.

French also has a simple future:

• nous planterons = we will plant

Both can refer to the future, but aller + infinitive is very common in everyday speech, especially for plans or intentions.

It breaks down like this:

• nous = we
• allons = go / are going
  (from the verb aller, to go)
• planter = to plant

So literally, French says something like:

• we are going to plant

This is a very common pattern in French:

• Je vais manger = I’m going to eat
• Tu vas partir = You’re going to leave
• Nous allons planter = We’re going to plant

In French, nouns usually need a determiner. Des is the plural indefinite article, like some or just a bare plural in English.

• une graine = a seed
• des graines = some seeds / seeds

So:

• planter des graines = to plant seeds

English often drops the article, but French usually keeps one.

Dans means in or inside.

So:

• dans deux grands pots = in two large pots

It is used because the seeds are being planted inside the pots.

Compare:

• dans le pot = in the pot
• sur le pot = on the pot
• près du pot = near the pot

In French, some adjectives usually come before the noun, and grand is one of them.

So the normal order is:

• deux grands pots = two large pots

Not:

• deux pots grands ❌

A useful pattern to remember is that common adjectives like grand, petit, jeune, vieux, beau often go before the noun.

Because it has to agree with pots, which is:

• masculine
• plural

So:

• pot = masculine singular
• pots = masculine plural
• grand becomes grands

Agreement pattern:

• un grand pot = one large pot
• deux grands pots = two large pots
• une grande allée = one large path
• deux grandes allées = two large paths

Because deux already acts as the determiner.

In French, you normally do not say:

• des deux grands pots ❌

when you simply mean two large pots.

You just say:

• deux grands pots

Numbers replace the indefinite article here.

Le long de means along or along the length of.

So:

• le long de l’allée = along the path / along the walkway

It is a fixed expression. It is best learned as a chunk:

• le long de + noun

Examples:

• le long de la route = along the road
• le long du mur = along the wall
• le long de l’allée = along the path

French avoids saying two vowel sounds separately in cases like this.

• de + allée becomes de l’allée

This is the usual contraction/elision before a noun starting with a vowel or silent h:

• de l’école
• de l’hôtel
• de l’allée

Here, l’ stands for la or le, depending on the noun. Since allée is feminine, the full form would be:

• de la allée ❌
• de l’allée ✅

Because allée is simply a feminine noun in French. Noun gender is something you usually have to learn with the word.

You can see it from the article:

• l’allée
  and in other contexts:
• une allée
• la grande allée

So if you describe it with an adjective, the adjective must also agree in the feminine form:

• une longue allée
• une belle allée

Allée can mean several things depending on context, such as:

• path
• walkway
• garden path
• driveway
• tree-lined lane

In this sentence, le long de l’allée most naturally suggests something like along the path or along the walkway, probably in a garden or yard.

A simple pronunciation guide is:

• Demain ≈ duh-MAN
• nous allons ≈ noo zah-LON
• planter ≈ plahn-TAY
• des graines ≈ day GREN
• dans deux ≈ dahn duh
• grands pots ≈ grahn PO
• le long de ≈ luh lon duh
• l’allée ≈ la-LAY

A few useful pronunciation notes:

• Final consonants are often silent:
  • grands → the d and s are not normally pronounced
  • pots → the t and s are silent
• allée sounds like ah-lay
• There is a liaison in nous allons:
  • nous allons → noo-zallons

Yes, a few.

Common points in this sentence:

• nous allons → liaison: noo-zallons
• des graines → usually no strong liaison in normal speech
• grands pots → final letters in grands are mostly silent
• pots → final t and s are silent
• l’allée → the l’ links directly to the vowel

Also remember:

• planter ends in -er, which is pronounced -ay, not like English er
• dans has a nasal vowel, roughly like dahn

Yes, absolutely.

Both are correct:

• Demain, nous allons planter des graines...
• Demain, nous planterons des graines...

The difference is mainly style and tone:

• nous allons planter = very common in everyday spoken French, often sounds like a planned action
• nous planterons = a bit more formal, neutral, or written

In many contexts, they mean nearly the same thing.

Because demain is an adverb of time here, not a noun.

So:

• Demain, nous allons planter... = Tomorrow, we’re going to plant...

But when demain is used as a noun, it can behave differently in certain expressions. In this sentence, though, it is just the time marker tomorrow, so no article is needed.
