Question: Calathea Croton
Hello everyone. My name is Barbara and I urgently need news on calathea crocata. I bought a plant this late spring; it was in bloom and very beautiful. Flowering lasted until the end of summer, but only of the existing flowers, while new leaves were born. I had noticed, however, that the leaves were not beautiful open as in the photo of the small "information" had with the plant, but tended to close. At the end of flowering the leaves also dried up, so I cut everything down to the base of the plant. After a few months some leaves have sprung up but they are already drying up without having grown so much. There is only one jet that has not made the leaf but is growing. During the autumn-winter I water the plant on average once a week, but I try to keep some water in the saucer. it's right? Would you please give me some "tips" to cultivate and make my plant bloom?
Calathea crocata: Answer: Calathea Croton
Dear Ms. Barbara,
We thank you for contacting us regarding the request for cultural notes on Calathea and regarding their recovery from the deterioration reported to us.
The Calathea also generically defined Marante from the name of their discoverer
they are all perennial evergreen species originating from the tropics of Brazil.
They are generally cultivated for their colorful foliage and some such as the Crocata, in its possession, also for the inflorescence (leaves transformed into bracts) of orange color.
They are therefore demanding plants in terms of environmental care, see temperatures, humidity and substrate, but above all in fertilizers, water and salinity.
From the state of your plants, in fact, we seem to have identified an excessive salinity or fatigue of the substrate as a predisposing cause.
We therefore recommend repotting by March with suitable soil and the use of fertilizers in the recommended doses
The excess of salinity probably caused by the type of tap water (rain is the best for tropical plants) added to a high use of fertilizers may have caused foliar desiccation and poor general turgidity of the plants.
