Hello. In this case, the deterioration may be related to stress from handling, transport and changing environmental conditions (Acclimatisation of indoor plants and Indoor plant placement according to environmental factors), as well as to unfavorable environmental and care conditions (high temperatures, low air humidity, insufficient light, inadequate watering and others, depending on the case) or the occurrence and spread of plant pathogens. Given the current condition of the leaf that can be clearly seen in the photo, this can be removed, as it will most likely not recover.
If the state of the other leaf is better, if the plant still has small leaves growing or if you consider that it still has a chance of regeneration, you can have in mind the specific environmental and care conditions described in our article: Monstera, plant care and growing guide. In the future, if necessary, it is recommended to regularly spray the leaves with water and/or place the pot on a layer of wet gravel. Watering is recommended to be done only when the soil is dry on the surface, with optimal amounts of water, so that the substrate is well soaked. Excessive watering can lead to root and base rot, leaf deterioration and can cause an imbalance in the plant. It is essential that the pot has water drainage holes and that water does not stagnate at the base of the pot. To stimulate root expansion, as well as to boost the plant’s resistance to stress factors, you may consider the regular administration of , when watering, as recommended on the label. The future development of the plant cannot be accurately predicted.
