check out the "growing under lights" forums. lots of people use artifical lighting (fluorescent shoplights, CFL's) to grow their tropicals indoors(citrus, orchids, plumerias, ets.) even down south i use CFL's during the winter when i move my tropicals inside the house.

Karen, I live in TX too and have a west facing balcony. It can get up to 120 degrees out there in the late afternoon. Some of my plants do the exact same thing(especially new growth) but as soon as the sun went down they would perk up again. So in your case the wilting is probably the heat and not need for water. I would follow Toni's advice and use the finger test before watering. If you can move them to an east facing exposure that would be good, but if you are in an apartment like me I would recommend using light colored pots, light colored mulch (someone recommended cedar) and maybe group some other pots around it to give some shade to the roots. I have a thai lime in a 10" white pot and it has survived the 100+ temps on my balcony just fine. You can also try double potting (putting the pot in a bigger pot with mulch or something in the space between). I have thought about doing that, but I dont have enough room. Lydia

All purpose fertilizer lacks the micronutrients citrus need - especially Meyers because they are bred to fruit so young and vigorously. Like roses, I find Meyers are "born hungry" and need feeding on a very regular basis. I buy citrus fertilizer and have a regular feeding schedule for my three trees. Liquid iron also helps 'green them up' so that is also fed on a regular basis. Citrus exhaust the soil pretty quickly; they'll continue to fruit, but lack of feeding definitely will shorten their lifespan.

I have one on Volk, one on Swingle and a few on their own roots. The most productive is the one on Volk, but it is not cold hard. For your location I would use Swingle if you want them grafted, or leave them on their own roots. Even if they get frozen on their own roots they will come back unlike grafted tree's where the rootstock will come back but not the scion.
