I bought this bougainvillea from a local nursery, put it in the ground, this was a beautiful red, and now, it's like a rust color! What happened to it? Is it something I did ? I sprinkled a little MG in the hole prior to planting it, not enough to burn the roots, it seemed like I was loosing flowers, but today I went out to add more mulch, and was surprised to see that it was very yucky looking. I also have another one, I bought this one a year ago, it seems to be happy where it is, but here again, the flowers were a bright pink, beautiful, and all of a sudden it to is changing color to a red. I"m posting 3 picture's, The first is the one I just bought that has the rust color, and the 2nd and 3rd picture's are of the one I bought last year, showing the natural color that's left on a few limbs, and the color it's changing to. I've always bought these plants, I love them, I just moved to a new home and brought the one from a year ago with me, the first picture is one I just bought a few weeks ago.
Can anyone tell me what might be going on. I do use a bloom booster on them occasionally, this year I treated them once so far, around 3 weeks ago, could this be the problem?
Thanks in advance for any input!!!
BTW, I have a beautiful one in the back yard, and it hasn't changed color, purchased after the one in the front that looks rust colored. It's a really pretty pink, and no, I don't have a picture of it! Jami
