Can not tell the kind of tree you have from the picture..that is the first thing needed to know.can you post another pic.. so to get a id..john

It may be that your azalea is having an indignation session after being moved from a snuggly glasshouse to a store to your room. First up - have a look at the potting mix. Often little azaleas are shipped in mix with a high peat content because it's lighter. However, indica azaleas seem to prefer something that both holds moisture - and lets the excess drain away. They are not fond of being deeply planted, or being in too big a pot. You mention that you can see roots sticking out. It is possible that it was poorly planted in the first place and, with things looking a little dire at present it could be worth repotting. The yellow balls you see may be slow release fertiliser balls. They can look ominous. If you squash one there's a sort of shell left and the inside is often semi liquid. If you are going to have a go at repotting choose a plastic container with at least one, thumb-wide hole in the bottom - or plenty of holes. Let it be no deeper than three inches and no more than half an inch wider than the root ball. Choose a potting mix with no water crystals, and little to no fertiliser. Go for one that suits acid-loving plants. Also get some sharp grit that's about 1-2mm (millimetres) diameter. NOT sand. Allow about one handful of grit to two of mix. If you're concerned about mix drifting through the holes - line the pot with a facial tissue. It will let water through and eventually rot away. Into the new pot put in about an inch of your well-stirred mix'n'grit. Tap the pot on the bench to settle it a little. Make a mini-cone of more mix in the middle of the pot. Gently take your wee plant from its present container and let the old dirt fall off. It is absolutely important that you leave the roots alone: no snipping. Trickle in the mix to barely cover the roots. No poking or pressing, please. It's done when the stem is clear, there is a small slope on the mix away to the edges of the pot, and the roots are thinly covered. Now put the pot into a container of tepid water and wait until the bubbles stop rising. Bring it out, let it drain, add a little more mix if watering has revealed any roots. Then cover the surface with more grit - leaving the trunk clear. On the matter of sunlight: I am accepting that Arizona sunlight and summer temps can be more than I get - although our UV ratings are horrendous due to holes in the ozone layer. That being so - indicas will take a fair amount of direct morning sunshine - and like to be in fresh air. It helps for them to get that sun as it seems to greatly improve flowering. If you can put your plant outside during the day over spring and summer - even into autumn - it will be healthier. A north-east location may suit best. They are frost tolerant to around -5C although the flowers turn to mush when it's that cold. What you may find is that you get dieback on the present stem structure and new growth coming from the base of the plant. You will have to start over with reshaping, though. It takes AGES for an azalea's roots to colonise a pot so be knowing that you'll need to take care when moving the plant. No fertiliser until March. Let it get its breath back... When azaleas dry out they can develop leaf gall. It's better to water by plunging the pot as you do when repotting than trickling water on with a watering can because that fine root mass can shed water better than a raincoat. Remember to turn your plant a quarter each week so it grows evenly. Later on - in a year or even a little longer, you can think about putting it back into a formal bonsai pot. There's no rush. Good luck ;-).

Well, I doubt if it was a matter of too much grit or gravel, but possibly being out in the sun too abruptly (what looks like dull outside to us is still so much brighter to a plant than what looks like bright indoors to us). And who knows, it's possible being repotted twice so soon might not have been the best idea (and you had no way of knowing that either, especially if other members were pressuring you to do it). What I think is that even if you lose this one (and you could... though stop trying so hard now and give it a rest, especially as almost leafless trees need less water) you can get another one, and you will have learned something from the experience, as we've all had to, it's just part of the process really, and I don't know anyone who's 'escaped' it, so join the club!

everyone else is correct, bring it outside asap. i'm not sure where you are in arizona, but you are probably close to zone 7. your tree is most likely a japanese juniper, these really prefer to be in a colder zone, but as long as you pay close attention you can make it work. you will want to check the soil several times a day. gently dig down an inch or so and if it's still moist then let it be. if it is dry, give it a good soak. as you are watering it don't worry about getting it too wet, the soil and pot are designed to not hold too much water. misting it once or twice a day is not a bad idea either. here is a good reference for general care: http://www.bonsai-bci.com/species/garden-juniper.html
