Ojalá las raíces no dañen el tronco, porque me gustaría que ese árbol siguiera floreciendo muchos años.

Ojalá is a very common Spanish word used to express a hope or wish, similar to I hope or if only in English.

In this sentence, Ojalá las raíces no dañen el tronco means the speaker is hoping that this does not happen.

A key grammar point is that ojalá is normally followed by the subjunctive, because it introduces something wished for rather than stated as a fact.

Examples:

• Ojalá llueva. — I hope it rains.
• Ojalá tengas razón. — I hope you’re right.

Because after ojalá, Spanish usually uses the subjunctive, not the indicative.

• dañan = indicative, used for facts or statements
• dañen = present subjunctive, used here for a hope or wish

So:

• Las raíces no dañan el tronco would mean The roots do not damage the trunk as a statement of fact.
• Ojalá las raíces no dañen el tronco means I hope the roots don’t damage the trunk.

Dañen is the third person plural present subjunctive of dañar.

Steps:

1. Start from the yo form in the present indicative: daño
2. Remove the -o
3. Add present subjunctive endings:
   • dañe
   • dañes
   • dañe
   • dañemos
   • dañéis
   • dañen

It is third person plural because the subject is las raíces.

Because the nouns have different gender and number:

• la raíz = the root
• las raíces = the roots
• el tronco = the trunk

So:

• raíces is feminine plural
• tronco is masculine singular

The articles must match:

• las
  • feminine plural noun
• el
  • masculine singular noun

The accent in raíces shows the stress and also helps signal that the vowels are pronounced separately:

• ra-Í-ces

Without the accent, Spanish spelling rules would suggest a different pronunciation pattern.

This is because raíz has a stressed í, and when it becomes plural, the stress remains:

• raíz
• raíces

Because el tronco is a direct object referring to a thing, not a person.

Spanish uses the personal a mainly with specific people, and sometimes animals or personified beings:

• Veo a María.
• Quiero a mi perro.

But with things, you normally do not use a:

• Las raíces dañan el tronco.

So el tronco is just the direct object with no extra marker.

Me gustaría means I would like.

The structure me gustaría que + subjunctive is very common when you want to say you would like someone or something to do something.

Here:

• me gustaría = I would like
• que ese árbol siguiera floreciendo = that that tree would keep flowering

This structure is used because there is a new clause introduced by que, and the speaker is expressing a desire, not a fact.

Compare:

• Me gustaría viajar. — I would like to travel.
  Same subject, so infinitive.
• Me gustaría que ese árbol siguiera floreciendo. — I would like that tree to keep flowering.
  Different subject, so que + subjunctive.

Because after me gustaría que, Spanish uses the subjunctive.

So:

• sigue = present indicative
• seguirá = future indicative
• siguiera = imperfect subjunctive

After a main verb in the conditional like me gustaría, Spanish typically uses the imperfect subjunctive in the subordinate clause:

• Me gustaría que vinieras.
• Me gustaría que lloviera.
• Me gustaría que ese árbol siguiera floreciendo.

This is a very important pattern in Spanish.

Both are possible, but they are not exactly the same.

• floreciera = flowered / would flower
• siguiera floreciendo = kept flowering / continued flowering

The structure seguir + gerund means to keep doing or to continue doing.

So siguiera floreciendo emphasizes continuity: the speaker wants the tree to go on blooming year after year.

Examples:

• Sigue lloviendo. — It keeps raining.
• Quería que siguiera hablando. — I wanted him/her to keep talking.

Yes. Siguiera and siguiese are both valid forms of the imperfect subjunctive.

So these are both correct:

• Me gustaría que ese árbol siguiera floreciendo...
• Me gustaría que ese árbol siguiese floreciendo...

In modern Spanish, -ra forms like siguiera are generally more common in everyday use, including in Spain.

Spanish demonstratives show distance or perspective:

• este = this
• ese = that
• aquel = that over there / that one farther away

So ese árbol means that tree.

The speaker is referring to a tree that is not being presented as especially close to them in the discourse. Depending on context, este árbol could also be possible, but it would slightly change the perspective.

Because Spanish often expresses duration directly, without needing for.

So:

• muchos años = many years
• durante muchos años is also possible, but less neutral here

Examples:

• Viví allí muchos años. — I lived there for many years.
• Espero que dure muchos años. — I hope it lasts many years.

In your sentence, muchos años means the tree would continue flowering for a long time.

Yes. The tense after ojalá depends on the kind of wish.

Here, ojalá ... no dañen uses the present subjunctive because the speaker is hoping about a real future possibility.

Other patterns:

• Ojalá no dañen el tronco. — hope about the future / a possible situation
• Ojalá no dañaran el tronco. — a more remote or less likely wish
• Ojalá no hayan dañado el tronco. — hope about something that may already have happened
• Ojalá no hubieran dañado el tronco. — regret about something that did happen

So the chosen tense fits a normal present/future hope.

It is acceptable here, and it helps separate the two parts of the sentence clearly.

The sentence has two main ideas:

1. Ojalá las raíces no dañen el tronco
2. porque me gustaría que ese árbol siguiera floreciendo muchos años

The comma creates a natural pause before the explanation introduced by porque.

In shorter sentences, Spanish often omits this comma, but in a longer sentence like this, many writers include it for clarity.
