Hey all!

Living near Dallas, Texas and we planted several evergreen azaleas (purple formosa, pink ruffle, Delaware valley) each planted in 18"x18" dug holes and backfilled with a 50/50 mixture of sphagnum peat moss and pine bark mulch raised to 2-3 inches above the surrounding ground. They have been planted for a little over 2 weeks now, have settled nicely and with the exception of a few yellowing leaves and some withering which seemed to be alleviated with a bit more watering they are growing nicely and are at the end of their blooms. Having said that I recently did a soil ph test resulting in perfect acidity as well as tests for nitrogen (depleted-zero amounts), potash (sufficient-surplus amounts) and phosphorous (deficient-adequate amounts). From what I have read I am finding that cottonseed meal is a great, organic, all around and well balanced fertilizer that contains the above mentioned nutrients as well as trace minerals that benefit azaleas. My concern is that, while our azaleas are considerably larger and older than the typical azaleas that one would find at a Home Depot or Lowe's, they are still new to our garden and I don't want to run the risk of laying down some cottonseed meal and harming or burning up the roots because they are still settling in. Just wanted to get some educated thoughts on this in particular. I'm new to gardening but I definitely did my research before planting these beauties, I just want to make sure that they get what they need while avoiding being over zealous and harming them. Thanks for all your help! First photo is immediately after planting 2 weeks ago and the other 2 photos were taken this morning...
