How to plant (transplant) Azaleas in an alkaline soil
Hi! Forgive my gardening ignorance, I'm a newbie, and I'd really appreciate some help from you experts.
I planted some Azaleas in my front yard a couple of years ago. I'm slightly less clueless now-- turns out my soil is completely alkaline (8.0). They have managed to live through my mismanagement, but of course they haven't thrived. I'd like to move these to a different location, so I want to know what I should do to the soil at that point.
The info I've found here is that I can use specific plant foods and mulch with pine needles to help bring acidity, but before even transplanting, I imagine that I should work something into the soil, then plan to try to add acidity regularly, how should I do this, and with what? Also-- coffee grounds? What should I do with them?
I'd appreciate any help, thank you!
