ALDEVAUX

The first thing to do is to remove the plant from the pot and examine the roots to see if there is no root rot. The roots should be firm, whitish but not have brownish or blackish rootlets. If there is root rot it should be repotted. This could be done throughout most of the year, although, the best times for repotting are in early spring.

At repotting, all the visible unhealthy roots only must be removed and the plant placed in a good very free draining soil so that no free water remains at the bottom of the pot. When the soil is free draining, you can water daily without problems because in that way the roots can then get as much oxygen as needed.

The tree should be pruned to remove all the dead branches (those that show no green coloration under the bark) and maintained at winter temperatures above 55 degrees F and also it grows best in high light and in sunny, warm locations. It needs as much light as possible and should be kept in a well-aired area where there is plenty of light and a temperature between 13-18 degrees C (55-65 degrees F. It should also get as much humidity as possible.

Be carefull not to over fertilise : chemical fertilizers may be used but should be diluted to approximately one half strength in winter so that valuable roots are not damaged and easily rotted.
Normally, if this is done new buds should appear in time. Best of luck.
