No ideas? New growth yellowing must mean something. I thought Foilage Pro would meet it’s nutritional needs especially with vinegar allowing it to release with a high pH water.

It always boils down to the lack of light and the soil choice with these. Next is pest and fertilizer.

If you are using vinegar which cause no harm at all at the dosage you are using and you are using Foliage Pro, you should have great success which it seems you are with the tree surving all it's been through. If you can keep it looking that good despte all of that then you are on the right track. I think it looks fine and I have been growing many for years. It will fill up in the spring after you have cut it back hard and more sunlight is in use.

Doing a good job. Remember to treat for mites once a month even if you don't see them. Use a well draing mix which you are and do not under or over water. Lot's of sunlight, and if you can't in winter, suppliment with something like flourecent! Fo my trees to do very well, they have to receive at leat 12 hours of light which is impossible in winter unless I use artificial lights. Along with that fresh air movement.

Thank you Val rie and Mike! I agree it is doing well considering all it’s been through! LOL It seems to love the 511 mix (thanks to all who pushed me to switch even though I was scared to) and it’s so nice to know it’s got a great draining mix. I moved it to the south side of the house now that the days are getting less light and its previous eastern location stops reciving direct sun by noon. It’s got a lot of baby leaves where it cut it back on certain branches. I don’t know if the yellowing at the veins a nutrient deficiency or what but it seems to only happen on new tender growth. I have a set of young leaves just go yellow on me. Is it the colder air at night? Lately it’s been in the low to mid fifties at night and reaching high 60’s low 70’s during the day. Should I bring it in for the winter? I hate to have it loose all of the glorious sun its been getting for my not very sunny house. Oh and I have been spraying it monthly with safer brand to keep mites, aphids, scales etc away. Thanks again for your comments!!!!

As long as your night temps stay at 55 or higher, it should be very good. In fact, many gardenia need cool night temps to initiate buds. But anything lower than that I would bring it in at night. It will stop growing and cause even more yellowing if the roots stop working.

It is much better outside. If you can even bury the pot into the ground on a sunny warm side of your home, it will be able to stay out much longer than one might think. The ground will keep your root much warmer than exposed pots.

So according to the weather forecast I posted above I should bring it in every night this week. I am going to bring it back out for the sun and warmth most definately. Thanks Mike. I would rather not bury it :)
