Where we live we have to plant them in pots of ericaceous soil - I think that means it's acidic, but in some parts of the country they already have acidic soil so they can go straight in the ground.
I think you have to have quite acid soil to grow azaleas well & these are beautiful, I do like the combination of the two colours. It's a wonder Ruby hasn't spied that peg but there again she probably put it there in the first place !!
Beautiful, Phil. Our azalea bloomed about a month ago. It is fun having a second Spring through photographs. I didn't notice the clothespin/peg til you pointed it out. Isn't it funny how much more observant we are about our "stuff".
