It depends on the variety, Sunflowers. Most only bloom once a year, but some Rutherfordianas can put on scattered bloom several times in a summer.

All like brilliant light, consistent watering, and frequent, light feeding. It will be even happier if it can go outside in morning or filtered sun in the summer. If possible, give it some humidity while it is indoors--it is very subject to spider mites, otherwise.

Thanks Tugbrethil. Much appreciated.
As my Indoor pinkish red Azalea seems to have stopped flowering - do I prune, pinch out the flowers and/or prune the stems?

I would gently pull off the dead flowers. If it is "having a bad hair day", now is also a good time to give it a trim.

Again, your response is most helpful....and much appreciated. Not many webs give you good advice and for free.

1) The azalea is still very green and full of leaves. How do I trim it ? Do I trim the green leaves/stems?

2) Do I need to feed it before it starts flowering again?

I know I am a pain....am always thinking of something else to ask... but will get there in the end.

If the general outline of the bush is ragged looking, just take a good pair of scissors and trim off thge outer inch or two, as if it were a hedge. If it's rounded and compact, trimming won't be needed.
Don't worry about being a pain! I'm just "paying it forward" from all the questions I asked while I was learning gardening.
