    We purchase a potted citrus tree about one year ago that has 5 grafts. Two orange, lemon, manderin and lime. About 3 mounths ago we repotted to a larger pot with holes on the bottom, stones for drainage at bottom, then cactus mix, the potting soil mixed with cactus mix around root ball. We have always kept the tree outside in mostly full sun. Watering has been intermittant soaking when dry, about once a week. The tree has done well but has only produced lemons and mandarins. Recently, within the last month,the mandarin graft was the first to completely turn brown and loose all leaves followed by the Lane Late navel graft and now one section of the valencia orange graft. These branches are all close to each other on the same side of the tree, however the lime branch is below these and appears just fine. Am I slowly loosing my tree? Are these grafts gone forever? I'm remembering about 5 months ago after a thorough soaking, we placed some citrus organic fertilizer with humic acid and soil microbes including mycorrhizae (7-3-3) in holes and we worked it into the soil. That was our first time fertizing and have not fertilized since. I'm not sure if we should fertize again, get a meter to be sure we are water adequately or do anything with the dead branches. Hoping to receive some suggestions, I love my tree.

    I hate to be the bearer of bad news , but the grafts are gone if there is no green wood left above the point where they were grafted. If there is any green wood left of them you may be able to revive it.

    Your tree has some serious problems, I am not that knowledgable about container grown citrus--maybe some of the container experts will reply-- but I do know you need to fertilize. The recommended NPK ratio is 5-1-3. You can find slow release fertilizer that is close to that ratio (Osmocote), or you can use a soluble fertilizer.

    My best suggestion is use the search function on this forum and read threads on container grown citrus, potting media, watering and fertilizing.

    Well, thankyou for your reply, however I am very sad. I don't know what caused the problem or how to keep it from taking over the whole tree. I will go ahead and fertilize I suppose and I will take your advice and check the forum on potted citrus. Thanks again!

    Most problems with container citrus are due to overwatering or poor choice of potting soil that hold moisture but very little air. Probably the next biggest problem would be fertilizer choice-- poor ratios, no minerals (leading to deficiencies). Salt buildup can also be a problem --so read threads on these problems and you can avoid most pitfalls.
