too much salt for banana?
I posted this in "Container Gardening" but figure I'd get more responses here:
I have a fairly large container garden in an apartment balcony here on the Phoenix/Glendale border. I have "normal" flowering plants and trying some bananas and heliconias.
The water seems to be VERY hard here and I water everything by watering can as there's no hose hook up.
My question is, I am thinking my bananas and others might appreciate decreasing the salt content of the water. I've heard of gypsum but not sure how to apply that with already planted plants in containers.
Any suggestions on what I might do?
