If the amount of light and water its getting is different from what it got in your office, then that's the problem. When I say the 'amount of water' I'm not necessarily referring to cups, but possibly natural humidity, and frequency of watering - if it's getting less light, it'll need less frequent watering, especially as it's later in the growing season too - yellow leaves usually mean too much water (and if your potting soil is 'normal' then it's mostly peat, rather than fast draining grit, and so is holding onto water for ages below the surface, so repotting might be considered). It may acclimatize to less light, but not if you haven't adjusted its watering issues to match. And consider humidity as well, a tray of water, with stones in it under the pot keeping it from touching the water (and rotting roots) will be more effective than a spray or two daily.

Hey, there! I've been growing these for quite some time, and I've overseen the growing of many others. They can be a fickle tree, but are well worth the effort. I can't add much to what's been written, as the advice is sound. Often, Pachira are sold in near-death condition, and so it may have been declining for a long time. Don't beat yourself up over it. It might be out of your control. As long as the roots haven't rotten, and as long as the trunks are firm, there's a chance. Even if all the leaves fall off, it could still recover. Several of us have lost leaves by putting them in the sun too soon, and the plants regrew a full compliment of foliage. I'll include some links, below, that might give you some ideas for a future approach. With more information, and pictures, we can offer even more specifically tailored advice. 1. This is a Thread I put together on re-potting my Pachira last Spring: Pachira (Money Tree) - Spring re-potting pics 2. This is a massive Thread that has spanned several years. Lots of varied information: Sick looking braided Money Tree 3. And lastly, these are the search results for Pachira Threads, which you might pick through: Pachira Search Results Josh

The pot doesn't look too big and if you just replaced the whole root-ball within the new pot and backfilled up to the same level as it was previously planted, moving shock should not be a problem. It looks like a glazed ceramic pot - is it planted directly into that? What sort of drainage does it have?

It's in miracle gro potting soil. This is its first year... it's actually about 7-8 months old right now. It's a hardy gardenia, so theoretically I could leave it outside, but the first freeze we got here (25F) resulted in frost bit leaves, and I decided I didn't want to risk it, hardy or not. Those frost-bitten leaves, strangely, have stayed on. I brought it in a few days after that, and about 3 days ago is when half the leaves dropped. They never turned yellow or black... they were still glossy and green, and just dropped. The bulbs are probably 3ft, maybe from the plant? They're in a typical ceiling fan light fixture (the fan is never on because it hums, so it can't be the breeze) centered over the table, and the pot is on the table. It's a very large pot, which brings the plant itself about 3ft from the fixture. I did some reading about grow lights and came to the conclusion that what's special about those is they have full spectrum light. I figured my daylight bulbs might be the same, but maybe I'm wrong and I need to go buy something special for it? I'll try the houseplant forum too.
