Wilted Gardenias?

I purchased two gardenia plants from Home Depot about two weeks ago. They were definitely in need of repotting, so I did. I also added one stick of fertilizer and watered each with one cup of water. They've been indoors in a sunny warm spot - and I have a humidifier on all day long. I haven't taken them outside because I'm in CT and it's still quite chilly here. Almost three days after I repotted them, they began to wilt with only a few yellow leaves. The dark green color has now faded to a lighter shade - but not pale. What could be going on? Should I throw them out and start over? Is there anything I can do to revive my plants?

Hey Green Bee,



You fertilized a plant straight from home depot, their soil is probably maxed out on fertilizer. Do your pots have drain holes? What did you use for potting soil? I think you need to remove the fertilizer sticks immediately. They are in shock to some extent also. When you transported, were they in a cold car for long? Do you have a sunny window?



Photosynthesis will help to make them green, but wilting, sounds like: transplant shock; transportation shock; over watering; too much fertilizer. Nothing you can do about the shock, now.
Reply:yeah wiltering could be shock but uncommon out of pots. If you have dug up one which was a well established plant it would be understandable. Needs sun and plenty of water. A lot more than a cup. Yellow leaves is also a sign of too much nitrogen in the soil.
