"There ought be a rose garden" is true if one promised to plant a rose garden.

That conditional is not true in and of itself. It would require one or more additional premises, premises which others might well have good reason to reject... — S
I have no clue what you're trying to establish as a valid objection. Actually, I have no clue what you think that that string of words means. There's a bit of a gap here in shared meaning.
Good to see you, by the way!
On my view conditionals are not truth apt. Truth conditions are not the sort of thing that it makes sense to say are "truth-apt" for they are a vital part, and elemental constituent, an ingredient - as it were - of what makes "truth-aptness" possible.
I have no idea what being true 'in and of itself' even means. No thing is true in and of itself. That reflects a gross lack of understanding regarding what sorts of things can be true/false and what makes them so.
Being true requires meeting truth conditions. Being called "true" requires meeting only belief conditions(personal warrant). Being logically true requires meeting only validity conditions. Being sound requires meeting both truth conditions and validity conditions, but does not require belief conditions.
Being true and being believed does not require language. Being believed to be true does. Being sound does. Being believed to be sound does.
Moral statements are truth-apt for the same reasons that other truth-apt statements are. They have truth conditions that can be met.
Furthermore, and well worth arguing over...
Pay closer attention.
Here's a report of what has actually happened more times than we can possibly know. We can know that it has nonetheless.
A sincere speaker says "I promise to plant you a rose garden on Sunday".
It only follows by virtue of what the statement means(in addition to having a sincere speaker), that there ought be a rose garden on Monday. This is irrefutable.
"There ought be a rose garden on Monday" is true each and every time someone voluntarily enters into a moral obligation to plant a rose garden on the day before.
That's what it means. Promises are moral statements, as a result of being about behaviour. Moral judgments are made about promise makers. Making a promise is voluntarily obligating yourself to actually perform certain behaviours(to make the world match your words).
Morality is all about what counts as acceptable/unacceptable behaviour. Making a promise is a moral state of affairs as a result of being something that happened that is morally germane/relevant.
Our ability to imagine that which has not happened has no bearing upon what has. The promise has been made by a sincere speaker. The world ought be changed in whatever way it takes to match their words because that's precisely what they mean when spoken sincerely.
Of course we can imagine unforeseen possible situations/circumstances arising that would no longer allow the speaker to keep their word. Reasonable people would not hold the speaker accountable in such cases. That does not change the meaning of making a promise when having a sincere speaker.
