Question from the user

<< Bonjour, depuis que j'ai installé mon dracaena chez moi, les feuilles sèchent et dépérissent avant de tomber. La plante se trouve à l'intérieur de mon appartement, plutôt à l'ombre, et je l'arrose une fois par semaine. Dans un premier temps, j'ai pensé que l'air était trop sec. J'ai donc vaporisé de l'eau sur ses feuilles quotidiennement, en vain. Elles continuent de tomber et des taches sont même apparues. Désormais, elles ne cessent de croître. >>

Auscultation and diagnosis

In view of the various elements made available to Frédéric Marque, his diagnosis is set to revolve around water. In fact, when he noticed the dracaena leaves drying out, his owner had the reflex to spray water on the leaves. This action certainly made the situation worse. In reality, everything indicates that the plant suffers from an excess of water at the level of the pot. This is called root asphyxia. Despite the excess water, the sick plant will react by drying out, in the same way as if it lacked water. Since the symptoms are much the same, it is quite complicated to draw a conclusion about the source of the problem. To be sure, it is advisable to touch the surface of the pot. If the substrate is wet, we can think of an excess of water. If it is very dry, then we will opt for a lack of water. In all cases, we must decrease or increase the frequency of watering according to our findings. In addition, by spraying water on an already weakened plant, the owner has favored the emergence of a new disease that affects the foliage and prevents growth. Finally, the pot seems far too small for a plant of this size and thus prevents its proper development.

The recommendations

At first, it is essential to regulate the watering of the plant according to the conclusions drawn by touching the soil present in the pot. Then, it is necessary to stop the vaporization of water on the leaves, because it is thanks to it that the fungus at the origin of the spots can spread on the plant. Finally, repot the plant in a larger pot, with potting soil to which you will have added fertilizer. These solutions will allow the plant to reinvigorate and resume normal growth.
