I live zone 6 area. I have a hibiscus plant which grew and flowered wonderfully last year. During winter, it was taken inside home and then then taken out at the start of the Spring. It has been watered and fertilized on a regular basis. Unfortunately, there was not a single flower this year. The growth is very good and the plant is very vigorous, but no flower at all.

Does anyone have any suggestions?

Thanks.

at a guess, too much nitrogen can lead to lush growth with no flowers.

Can you use some kind of Phosphorus, to immobilize some of the "high nitrogen" ??

Should I plant corn, to offset this high "Nitrogen" ??
