Take avocados off your list. They are very thirsty! High maintenance. According to an article I read on yahoo this morning, due to California's drought and the costs of keeping them alive and healthy, Avocados are the next caviar! We have 3, and they do require a lot of water. Most plants require water while getting established. Prickly Pear might be your best bet. I have one fig tree that wilts in the heat. Violette De Bordeaux. Panachee Fig turns yellow and drops her leaves if her emitter is clogged and she doesn't get the water she loves. We named one of the paths that meander through our acreage "Olive Lane," because we planted two Olive trees to flank it. They both are on the drip system. One tree is thriving. The other is stunted. Both very green. For a year one had no water and the other did. We didn't notice the broken emitter. A drought tolerant vegetable tree is Moringa Oliefera. We grow that as a hedge and use the leaves in salads. I'm not a fan of the pods, but the trees buzz with bees after the flowers.

Hi, I'm in the same boat. I haven't been able to find any of those. A member of the citrus forum pointed out that Four Winds Growers does have Australian Finger Lime: https://ssl4.westserver.net/fourwindsgrowers.com/secure/consumer/ Sid

The soil just under the base of the tree may be damp, but I'm betting the rest of the soil in that pot is bone dry. That tree looks like it's dying of lack of water. If I were you I'd take it out of the pot and examine the soil. Sometimes potting mix can seem wet on the surface but have large dry pockets down deeper. If it's a peat based mix, and most store bought are, if it gets too dry one time, it's almost impossible to re-wet from just watering from the top. It would need to be submerged in a larger pot that does not drain, and really let it soak for 24 hours. Then remove and water normally. Imo, 2 weeks without watering is way too long.

Evan, I've got flower buds, not yet open. I will probably try and let one of the six buds bloom and get ripe (assuming I can paintbrush pollinate the flowers successfully). I got this as a very young twig graft from Stan McKenzie this spring. I had seen he had acquired a red finger lime which had one or two fruit on last year during a visit to his farm during the fall, so I beat feet back when I knew he had this (which was his first graft from that plant). Mine cost $20 from Stan (no shipping since I was in person picking the baby up). I'm sure it will take a few more years to reach Evan's plant size, but that works for me, since I have to haul my tropicals in for winters!
