After transplant to a small pot, remove the heart from the seedling as it grows to facilitate branching. 

The moisture

Disease control of Heliotropium arborescens

Heliotropium arborescens is easy to age after a few years of cultivation, the flowering parts continue to move up, the base leaves gradually fall off with the lignification of the stem, often prone to the lower part of the plant bald phenomenon, so generally in the cultivation of 2 ~ 3 years after that is to use cuttings to culture new plants. Although Heliotropium arborescens is a sub-shrub, it is often cultivated for one or two years because its branches are soft, the old plants are scattered and the posture is not beautiful.
