How to get my hibiscus blooming good again

parrothead_fa(z10 FL)December 10, 2006

Hi, I'm new to this particular forum, wish I'd tuned in to it a while back. I have 3 standard hibiscus shrubs, the red or peach variety you get at most garden centers in 3 gal sizes. The first year or two, they bloomed like crazy. Lately, I've been getting a lot of growth, but not many blooms. I have had to cut them back severly 3 times this year, because they keep getting so tall they obscure the lights on the outside of the house. I don't want them to be real short, but 6' plus is a bit rediculous!

Is there a way I can train them to remain a bit shorter, 3-5 ft would be ideal, and produce a profusion of blooms? They are just regular garden variety hibiscus, but look so lovely when they are covered with 6" flowers. The sprinklers water them every other day, and I fertilise them with a 12-6-9 fertilizer twice a month. We are in zone 10 in south Florida. Any input would sure be appreciated.

Dave,
Since hibiscus bloom on new growth, pruning, although necessary sometimes, will stop that branch from blooming. It takes about 3 months for enough new growth to be produced for new blooms.
I take it you want to keep the standard shape. You'll have to prune it back quite a bit, so that when it does recover from the pruning and start to bloom, it's still a size you want.
What some people do, so that they can still enjoy blooms while keeping the plants size under control, is to prune 1/3 of the branches, leaving some of the branches alone to keep blooming. When the pruned branches bloom again, then they prune back another 1/3...etc.
Hope this helps,
Barb

Since I pruned all of my plants back does this mean they won't bloom at all this year, or just how long will it take to recover? I wish I'd found this site last year. I'm a fairly new gardner and learning through trial and error has cost me some beautiful plants and lots of dollars.

Three months of good, bright light should be enough to start getting flowers.

Water with 5 gallons of water and 5 tablespoons of Epsom salts monthly. Every 3 months, add 2 tablespoons super phosphate to the water. They will bloom like crazy.

i cut my Hibiscus back to 3" from the ground last winter. Stalks were about 3/4" round. I waited. All of a sudden in mid spring up shot new shoots.
Now it about 5' tall , very heavy on it's self.
No blooms yet. I water heavy regularly, here it is mid June & no blooms!
Should I tie the tree up to a post or let it be on its own?
Also, will I get blooms this year due to cutting all the way back last winter???
Please help someone!!

I'm new at this, but from what I've read, certain Hibiscus species (the rose-mallow and Moy grande) do not bloom till June, so I would be a little more patient and it will probably bloom in the next couple of weeks if you leave it along.

I was not getting any blooms after placing the pot back outside. So I repoted it in a larger pot in april I also added time release fertilizer. No blooms yet. I am taking the plant back inside. Will it ever bloom again.

They all love food and water. My Red Texas Star Hibiscus will be blooming until our weather gets too cool. Then I hope my Confederate Rose Hibiscus kicks in and blooms.
