I am located in South Portugal. I bought one wollemi in the Sotheby's auction October 2005. It is kept in a big pot outdoor. The tree was fine until the summer 2006 (here the summer can reach up to 60ºC at full sun and 40-45ºC at shadow). The tree began to die which was a cause for very distress for us. We made our best but the main branch died. Then, other three minor branches began to grow and somehow replaced the bigger one that died. Now, almost all the lower branches have their leave tips drying and dying. We do not over water and only give water when the soil dries in the upper 5 cm. When we give water to the tree we always put a common water soluble fertilizer for conifers. Does anyone have any clue to what might be happening? Over water is not. Underwater is not. Over dose of fertilizer is not. Under dose of fertilizer is not (we follow the label instruction written in the fertilizer box). The tree has direct sun light about 3 to 4 hours daily. Can it be a disease? Can it be a fungi disease? Does this kind of diseases make the leaves tips dry and die? I did not cut completely the older branch that died in the summer because I was afraid of somehow hurting the tree more. Shall I cut it complete? Does its existence may cause any serious disease to the tree? If some one can help I would be very grateful. I can send some photos. Thanks Luis
