Hibiscus stopped blooming

9 years ago

After 3 years my two large potted hibiscus stopped blooming after feeding them high nitrogen food several times. Here is what is different this year:
1. I bought some larger clay pots and set the large plastic pots inside. They do not touch the bottom of the clay pots because the rim of the plastic was larger so the are sort of suspended inside the clay pots which have a hole for drainage.
2. They are getting plenty of sun but slightly less than previously. Remember it gets to 100f here in Dallas area. I water in the high heat every morning and they are lush and green. But no flowers. Fertilize weekly with either boggie food from Callaways or miracle grow.

Should I move them, take them out of the clay pots or trim their roots??????

you might try more potassium? HVH recommends lots of potassium for help blooming. and out of curiousity - with the pot in a pot theory is the temp between the pots hotter or cooler than previously? just a thought i had.

Most plants will put blooms on hold when they are hit with high N fertilizer in order to grow the green parts.
You want low N high P (phosphorous).

Stop fertilizing.
Stop watering everyday.
Water in the morning if the leaves are wilting in the morning (not afternoon).

I live in the Philippines and the same is happening to mine cause I hit them with a high nitro fert about 2 months ago. They are lush and green but no blooms and I struggle with the care here cause I cant find info on the tropical weather I now live in, but I have learned through HVH that hibiscus do not like phosphorous but love potassium. Now I will leave them alone for a little while and just water for a couple weeks and begin a half dose of high potassium fert once a week and see what happens. I also use osmocote in the pots so I am not sure if I am over fertilising or under, by the way I am new to the gardening game and would love advise.

What evilscott said. He's right. Stop fertilizing for awhile.
