Problems with Potted Roses in the Desert - Knowledgebase Question

I have several rose trees in large pots that I purchased about 8 months ago. I have already lost 1 and another is close behind. They were replanted in large pots with good mulch soil. 2 of the 4 remaining are doing well. One has new growth with wilty leaves. The other has lost most of its leaves and the new growth gets brittle and dies. I have good irrigation and they don't sit in water. Soil is kept moist, but not wet. The leaves would turn brown/crusty on the edges, then yellow and wilt. I was told that potted roses should be fertilized every watering (use a rose fertilizer) and it seemed to do well with the others, but not these two sick ones. I have also done a good drinching to make sure the salt is washed out through the holes, used bone meal, but no noticeable improvement.

1/4 to 1/2 the strength to reduce the chances of fertilizer burn.

I hope this info helps. There are several very active rose clubs in the Phoenix area. Visitors are always welcome at their meetings. Phoenix Home & Garden magazine lists the clubs and when they meet in their "Around Arizona" section at the back of the magazine. Good luck! 1/4 to 1/2 the strength to reduce the chances of fertilizer burn.
