I think they enjoy some bit of sun and even if not 10 hours of hot sun, but the sun and temperature right now are not summer level, so I think there is another factor.

When you water, does the water run out easily or does it at least get absorbed and some stay in the pot?

At the same time, if the pot is too moist and even water-logged, then the plant also will show signs of blooms fading and new buds not fully developing.

As for bloom time, did you get one of those that will bloom again in the same year ? If not, I think they usually just bloom once from what I've seen.

Hi, thanks for replying! When I water, the water get absorbed and stay in the pot. I noticed that when I water, the blooms would suddenly look really well the next day. I read that azaleas like lots of waters. I also found out that what I have is a kurume hybrid azalea. I'm not too sure if it will bloom again this year though :(
