THE AGRONOMIST ANSWERS ON HOW TO GROW AND CARE FOR PLANTS
WHY DO THE LEAVES OF MY DRACENA BECOME BROWN?
QUESTION OF LORELLA
I have had a dracena marginata for more than 4 years.
At first I kept it on an outdoor veranda, but then I moved house and put it in the kitchen, in a bright place and it started to look beautiful, even making fragrant flowers in November (I live in Sicily).
This year in November he made other flowers much more flowers than last year. But now it starts to have brown leaf tips and the leaves turn yellow. I would understand if they were the lower leaves, but they are the upper ones, even those recently born.
I take care of it as always, never moved it, so what can it be? Please answer me because I care a lot about that plant. I am attaching two photos of the leaves.
Dear Mrs. Lorella,
after two years of intense flowering, a recovery phase is quite legitimate. A bacteriosis could also be established due to the decrease in sugar reserves. Probably then the soil fell down, occluding the ventilation holes. It is therefore necessary to flare and repot with sandy soil, placing at least 2 cm of expanded clay on the bottom of the container, ensuring air passages for at least 50% of the pot bottom.
The tips with yellowed leaves must be eliminated with a good pruning of the bearing branch.
It should be ascertained that there are no cochineal attacks in progress, in this case treatments with white oil are necessary on the whole plant.
The waterings must be almost suspended until the appearance of new leaves, when it will also be possible to go back to fertilizing.
I also recommend placing the plant in a bright spot, removing the saucer and removing the container from the floor with small pieces of wood.
Looking forward to re-reading positive developments, I offer cordial greetings.
