What are people using to kick up the ph for hibiscus? I just checked several of my pots and our hard water in doing a number on them.

Don't suppose there's much opportunity for you to collect rainwater in AZ, huh. Wish I could send you some, it's pouring here.

Miracle-Gro used to have a good product for acid-lovers called Mira-Acid.

You could try mixing your coffee grounds and/or tea leaves into the potting soil. I'd also refresh the potting soil at least every year.

I can't really say it has helped much but I did get a bloom on my hibiscus so maybe... I get coffee grounds from a local cafe and dump a couple inches across the bed that the hibiscus is in. It makes it nice to water or when it rains, I can smell coffee Rolling on the floor laughing

Oh, I've got horribly high PH as well, sitting on a pure limestone rock down here. I swear even the rain is high PH, I'd like a little acid rain.

Thank you all for the help. I guess I need to put more coffee grounds on the plants. Perhaps I will water them with a batch of plant coffee. I was very surprised what their PH was. I have flowering non stop but I also have several trees and plants.

The other thing I do to lower the PH is once a year (before the rainy season, about now actually) I add peat moss to all the planting beds. I have most of my garden area raised a bit so that I can amend the horrible soil. A lot of soil washes away in the rains, right down through the limestone. So I replenish it with peat moss and hope that the rains mix it in to the regular soil.

What is the PH preference for Hibs. That's one thing I rarely pay attention to.

I believe they are like gardenias and azaeleas and prefer an acid or lower PH. I have problems with all of those plants, they don't do well for me here.
