I would repot right now. The problem is to be found in the root/soil combination. You may be watering too often for the soil. The soil may contain an accumulation of fertilizer salts. Repotting into the correct soil for comtainers will solve the problem. Al

Thanks Al. I haven't repotted because I'm having a really hard time finding your pine bark fines. Is there an "easy to find" at Lowes or Home Depot substitute? My DH and I have looked and looked, and they don't exist anywhere here that we can find. What is a substitute? I have some plain old dirt (clay) that is left over from planting a couple citrus, so I could use that in the mix with some vermiculite, but I'm stumped on those pine bark fines. Thanks!

A little update. I found a nice potting soil at a local nursery (not HD or Lowes). It is organic Gardner & Bloome Potting Soil and includes Fir bark, Forest Humus, Peat Moss, Perlite, Chicken Manure, Worm Castings, Bat Guano, Kelp Meal, Alfalfa Meal, Oyster Shell and Dolomite Limes. They suggested I buy Iron Chelate for all my plants also, and so I did that too.

I also took my little sad olive tree there and they said that the problem was due to water. I will put it into a new pot this weekend!

I hope this does the trick!
