I don't claim to be an expert, but since it happened right after the repotting, and you haven't changed its location or watering regime, it seems like the problem is the soil or the pot. Since there's more soil now, the plant should need watering less often than it did before, so my first suspicion would be overwatering, although (without knowing your climate) every two weeks in summer seems pretty infrequent. Just in case, I'd check to make sure it's not root rot. I've had plants get the rot right after repotting, I guess because the pot or soil were infected or because it was susceptible at that point. Turn the plant out of the pot--are the root tips firm and white? If they're brown and mushy, that's rot. Sometimes plants with root rot can be saved by immediate intervention--remove the plant, trim the diseased roots, throw out the potting soil (the entire bag), bleach the pot to sterilize it, and repot, maybe adding a little sand to improve drainage. Keep the plant on the dry side for a bit and see if it recovers.

I am in austin and i grow gardenia outdoors. i get them out of their nursery pots immmediately. i use a lrg container (at least 2x the pot they came in), the deeper the better, with good soil, a thick layer of good pine mulch (I think the pine is very important). they reside on a porch that gets about 6-8 hrs of sun per day, most of it in mid-afternoon. the temps have reached 108 there. i use liquified seaweed once a week for at least a month when i first plant them in their containers so they get a good start and never purchase new plants may-aug. i feed them half strength miracle gro once a month in march, apr, may and again in sept, oct, nov. they produce beautiful, fragrant flowers like clockwork. i also have a yellow hisbiscus that grows right along with them. (also, a tx star hibiscus has a smaller bloom but is very heat resistant, i dont have the proper name for mine, common 'hawaiian type'). i treat it just the same as the gardenia, it's 3yrs old, about 4 1/2' tall and it blooms nicely. i water very early morning as a rule, but water at a sunset may-aug to avoid steaming the plant, avoiding the leaves as much as possible. i am not sure why you would need pea gravel, it is my experience that gardenia prefer very rich soil. i grew gardenia in fla and thought i wouldnt be able to in texas, but they have performed well in containers. if you get alot of wind in your area, consider a spot that will block it. i hope i have helped. Good luck!

Leondra, Are they Radicans? Is that why you are calling them dwarf? In any case, what zone are you in? How much sun do they get? How close to the cement are they? The first pic doesn't look bad at all, but the second pic doesn't look too good. Are they watered? I am in zone 8 in SC, so most of our gardenias are out of the winter mode, I am going to guess that you are in zone 8 or above, and if so, you might want to try watering them if you haven't had rain in the past week. Brown is bad with gardenias, sorry, yellow is nothing to worry about. They are pretty hardy, despite what everyone says, so, just check to see if they are really dry and make sure they get water when they need it. You have them mulched, which is good. You should see new growth in the next couple of weeks, if you don't, that also is a very bad sign.

Exactly, try to just keep it alive until you can put it back outside again. Most look like crap by the end of a winter indoors unless they are held in a very warm humid greenhouse with moving air and full sun. If you want hardly an issue at all, as long as the back porch does not get below 40 degrees at anytime. that is where I would put mine making sure not to over water with some supplemental light unless that porch gets lots of daylight and sunlight. When it comes to mine, I would much rather keep them on the colder side to prevent unwanted wilted growth, pests and dropping leaves. I also use mainly fresh water, bottled, or rain water. NOT TAP. No problem. Keep us in the loop please. Spray the leaves often and use a running fan 24/7
