ame ga hurisou nara, beranda no syokubutu wo naka ni iremasu.

Because 降る is an intransitive verb: it means to fall or, with weather, to rain.

In Japanese, the thing that does the action with an intransitive verb is usually marked by が, not を.

• 雨が降る = It rains / Rain falls
• 雨を降る is not natural Japanese

So 雨が降りそう means it looks like it’s going to rain.

Here, 〜そう means it looks like... / it seems like... / it appears that...

So:

• 降りそう = looks like it will rain
• 雨が降りそう = it looks like it’s going to rain

This そう is based on appearance or signs you can observe, like dark clouds or wind.

It is different from the hearsay そう:

• 雨が降りそう = it looks like it will rain
• 雨が降るそうです = I heard that it will rain

Those are different grammar patterns.

Because these are two different kinds of そう.

1. Verb stem + そう
   expresses appearance

   • 降りそう = looks like it will rain

2. Plain form + そうだ
   expresses hearsay

   • 降るそうだ = I heard it will rain

Since this sentence is talking about the situation looking rainy, 降りそう is the correct form.

なら means if or if it is the case that.

So:

• 雨が降りそうなら = if it looks like it’s going to rain

It sets up a condition for the main action:

• If it looks like it’s going to rain, I’ll bring the balcony plants inside.

Compared with other conditionals, なら often has the nuance of:

• if that’s the situation
• if that turns out to be true
• in that case

Both can work, but the nuance is a little different.

• 雨が降りそうなら = if it looks like it’s going to rain / if that’s the case
• 雨が降りそうだったら = also possible, a bit more like if it seems like rain

なら often sounds like the speaker is reacting to a condition or making a decision based on it.

In this sentence, that fits well:

• If it looks like it’s going to rain, I’ll bring the plants inside.

So なら feels natural for a practical decision.

ベランダの植物 means the balcony’s plants or more naturally in English, the plants on the balcony.

Breakdown:

• ベランダ = balcony/veranda
• の = links nouns, like of or a descriptive connector
• 植物 = plants

So ベランダの植物 means the plants associated with the balcony, which in natural English is usually the balcony plants or the plants on the balcony.

Because ベランダの植物 is a noun + の + noun structure.

Here, ベランダ is directly modifying 植物:

• ベランダの植物 = balcony plants / plants on the balcony

This is a very common pattern in Japanese.
It does not need a particle like に or で here because ベランダ is being used as a noun modifier, not as a separate location phrase.

If you said:

• ベランダにある植物 = the plants that are on the balcony

that would be more explicit, but ベランダの植物 is shorter and natural.

Because 植物 is the direct object of 入れます.

• 植物を入れます = put the plants in

The verb 入れる is a transitive verb, meaning it takes an object:

• 何を入れる？ = What do you put in?
• 植物を入れる = put in the plants

So を marks the thing being moved.

中 means inside and に marks the destination.

So:

• 中に入れます = put [them] inside

Here, に shows where the plants are being moved to.

You can think of it as:

• 植物を = the plants
• 中に = into the inside / indoors
• 入れます = put

So the whole part means:

• bring the plants inside
• put the plants indoors

Yes—literally, 入れる means to put in.

But in a sentence like this, natural English often translates it as bring inside because that is what you would normally do with plants.

So:

• 植物を中に入れます literally = put the plants inside
• natural English = bring the plants inside

Japanese often uses a straightforward physical verb where English chooses a more situation-based translation.

Because 入れる and 入る are different verbs:

• 入れる = to put something in (transitive)
• 入る = to enter / to go in (intransitive)

In this sentence, the speaker is doing something to the plants, so a transitive verb is needed:

• 植物を中に入れます = I put the plants inside

If you used 入る, the plants themselves would be the ones entering:

• 植物が中に入る = The plants go inside

That is grammatically possible in some contexts, but it is not the usual way to describe a person moving them indoors.

In Japanese, the non-past form often covers both:

• present/habitual
• future

So 入れます here means something like:

• I will bring them inside
• I bring them inside (as a regular action)

Because it follows a conditional, it is naturally understood as future:

• If it looks like it’s going to rain, I’ll bring the plants inside.

Japanese does not always need a separate future tense the way English does.

The subject is omitted because Japanese often leaves out information that is clear from context.

In this sentence, the understood subject is probably I:

• (I) will bring the balcony plants inside.

But depending on context, it could also be:

• we
• someone in the household
• the speaker, as a general habit

Japanese very often drops pronouns when they are obvious.

Sometimes yes, but the nuance changes.

• 雨が降りそう is the most neutral and natural way to say it looks like it’s going to rain
• 雨は降りそう gives extra contrast or emphasis, something like:
  • As for rain, it looks like it’ll fall
  • At least it looks like it will rain

In ordinary conversation, が is more natural here because it simply marks rain as the thing happening.

植物 is perfectly correct and natural, but it sounds a little broad and slightly formal because it means plants in a general sense.

Depending on the situation, people might also say:

• 花 = flowers
• 鉢植え = potted plants
• 観葉植物 = houseplants / foliage plants

So:

• ベランダの植物を中に入れます = natural and clear
• ベランダの鉢植えを中に入れます = more specific if they are potted plants

The original sentence is fine, especially for a textbook-style example.

Yes.

• 中に = inside
• 家の中に = inside the house
• 室内に = indoors

All are possible, but the nuance differs:

• 中に is simple and conversational
• 家の中に is more explicit
• 室内に is a bit more formal or written

So the original sentence sounds natural and efficient:

• ベランダの植物を中に入れます = bring the balcony plants inside

It could be either. The Japanese sentence by itself does not force only one interpretation.

It can mean:

1. A future decision

   • If it looks like rain, I’ll bring the balcony plants inside.

2. A habitual action

   • If it looks like rain, I bring the balcony plants inside.

Context tells you which one is meant. In many situations, English would prefer I’ll bring them inside, but both are possible in Japanese.

The structure is:

• 雨が降りそうなら = if it looks like it’s going to rain
• ベランダの植物を = the balcony plants
• 中に入れます = put inside / bring inside

So the pattern is:

[condition] + [object] + [destination] + [verb]

More abstractly:

If X, then I do Y.

This is a very common Japanese sentence pattern.
