Question: Anturium with white patina
I have an anturium for a year, considering that the roots came out of the vase and the leaves turned yellow, they told me to repot it.
Once this is done, a white patina like mold appears at the base of the plant. I had noticed something similar even before repotting, but now the situation is degenerating.
What can I do?
Answer: Anturium with white patina
the anthurium is a beautiful evergreen herbaceous plant native to South America; in nature it lives in tropical and subtropical areas, where the climate is decidedly very different from the one present in the apartment, for this reason care to obtain a healthy and luxuriant anthurium must be followed constantly, avoiding excesses. The white patina present on the surface of your vase is probably mold, which, having developed from the plant's collar, was obviously transported from the old vase to the new one; generally this type of fungal attack, is averted by the change of vase, but only if in the decanting one intervenes removing all the soil that is nestled around the roots. Since the development of the parasite has not stopped, I believe it is necessary to carry out a treatment with a fungicide; there are two types of fungicide, one that must be sprayed on the fungus, and another, called systemic, which must be mixed with the water of the watering and used on all the soil, so that the plant absorbs it; I believe it is appropriate in this case to use a broad-spectrum systemic fungicide, as also the yellowing of the leaves was a symptom linked to the fungus. I remind you that this type of problem tends to develop more frequently in vessels in which stagnant water is constantly present; anthuriums need regular watering, from March to April until September, and sporadic in the autumn and winter months; therefore, water the plant only when the soil tends to dry: with a finger you feel how wet or damp the soil is, if dipping your forefinger to the first phalanx you feel the substratum fresh and humid, it sends back the waterings of at least a day or two . In any case, avoid leaving stagnant water in the saucer. Anthuriums, however, also love environmental humidity, and therefore are often prepared to vaporize the foliage and flowers; this operation is carried out when the climate is very dry, ie in July and August, when summer is hot and muggy, and in winter, because heating systems tend to dry the air very much. A thin whitish patina on the vase, which almost forms a crust, could also be given by the limestone present in the water of the watering, although it seems strange to me that so much limestone has already settled after repotting. If it is a creamy white coating, rough to the touch, then the water you supply to your anthurium is simply too limestone, and it will be sufficient to break the crust with a small hoe or fork, and to decant the watering water for at least one day before supplying it to the plant.
