Hc, once you see flower buds, it can take anywhere from a few days to two or so weeks to open..Flowers don't last long though..It's what's under that counts..the fruit.
One thing..some citrus flowers open at night..in fact, many are more fragrant once the sun goes down..I get to bed about 1am, and citrus in my room opens its flowers when I get to bed..Toni

The buds are teeny.. there are a couple of about 1/2 inch. It's hard to belive that they're gonna become full flowers in one day especailly the teeny ones. MAybe my questions was misunderstood. They are however growing slowy and steadily. I can't wait for them to bloom!! Very excited!!

Do they have any scent yet? So, the buds are fully closed, is that what you mean?
Hopefully, with care, they will open..and again, check at night..
I get excited, too, when citrus bloom..lol..and the house smells wonderful..T
