Referring to cherry blossoms:

> 咲き始めてから **１週間から１０日ぐらいすると** 、たくさん花が咲いてきれいです。  
>  After they start to bloom, from one week ???? lots of flowers will bloom
> and (look) pretty.

I'm struggling to understand the part in bold. If I read it literally I get
"When it makes around 10 days from/after a period of one week". Logically,
therefore I get "Lots of flowers will bloom around 17 (10+7) days after they
first start". Obviously I think my analysis is nonsense.

My guess is that it reads "Lots of flowers will bloom after a period of around
7 to 10 days from when they first start". Is this correct? Is there a way to
break it down logically?

More generally what are the common ways to express an interval of time after
which something will happen? I would have tried something like:

> 7日と10日ぐらいのあいだに

but that feels incomplete. It seems to be lacking the idea of **later**. I
know I can says "2 days later" as 2日後に. I guess " **around** 2 days later"
would be 2日後ぐらいに, but I expect 7日と10日後ぐらいのあいだに is completely wrong.

question
grammar time
Expressing intervals of time, and AからBすると
> 「咲{さ}き始{はじ}めてから[１週間]{いっしゅうかん}から[１０日]{とおか}ぐらいすると、たくさん花{はな}が咲{さ}いてきれいです。」

I will start with the word that you did not even mention -- 「する」. In this
context, it means " ** _to pass_** "; It is often used to express the passing
of a specific length of time. Whether or not one actually uses the verb "to
pass" in one's translation is a totally different matter. Personally, I would
not.

Next, the 「と」 is conditional, of course. Again, that does not mean one should
use "when" or "if" in one's translation. I would not use it.

> 「Time Length + ぐらい + する + と」

means:

> "within approximately (time length)"

In this case, the time length mentioned happens to have a range of 一週間 to １０日.
**「から」 can singlehandedly express a temporal or spatial "range"**. I mention
this because there might be people who thought that 「から」 could only be used to
describe a starting point.

Thus, my own TL of 「１週間から１０日ぐらいすると」 would be:

> "within approximately a week to 10 days"

Being a Japanese-speaker, I have no idea where you would get the idea of "17
(7 + 10) days", but I can assure you that that is not what 「１週間から１０日」 means
regardless of the context that the phrase appears in.

(You mentioned 「7日と10日ぐらいのあいだに」, but if someone said that to me, I would
probably think he was trying to say " ** _between the 7th and 10th of a
certain month_** ".)

The key word here is 「から」 for expressing a range. 「と」 seems quite out of place
to my Japanese-speaking brain. I could not use a 「と」 if I had to rephrase
「１週間から１０日ぐらい」. It can be rephrased to 「７日から１０日ぐらい」, using 「一週間」 would sound
more natural.
