I've found a solution, I just pee on mine! I also dose it a little with some cheleated iron with copper and it seems to love it. I've found some plants do hate wee wee, at least roses sure do. The leaves turned brown within days.
Tell me, do you wipe yourself with your left or right hand? Toni
Yep, I wee on mine as well (not even watered down as some forums suggest - just straight on). I also wee on my murraya. (and no my roses didnt like the wee either - but they LOVE the tea bags I give them). The other thing I've found that cures the gardenia leaves from turning yellow is, if in a pot, put it on crocks (so the water drains really well), and then water daily. serious. they love the daily watering. I barely even use epsom salts anymore with this crock - daily water - and wee recipe - and i've never had yellow leaves on my gardenia since. Aaaand for further thriving i recommend giving it diluted worm juice - just sends new growth out like there's no tomorrow.
can't wait to tell my husband this one! My sons used to pee around the perimeter of our yard to keep the deer away - but for yellow leaves? Worth a try, I guess!
Never heard of this trick. I might have to give it a try :)
I've found that Gardenias can adapt to many different kinds of environments. They perform at their best when the environment doesn't fluctuate too rapidly. Good drainage, mulching, and regular watering/feeding with consistency generally brings amazing results!
