Question: stromanthe

Good morning,
in the vase of the stromante 4 thin white mushrooms were born with the umbrella hat at the brownish center. The plant seems to be fine, but what should I do? Are they harmful? Should I take them off? Why are they there?
Thanks in advance

Answer: stromanthe

Dear Francesca,
stromanthe is a beautiful leafy plant, native to the Brazilian rainforests; having said that, it is quite clear what is the ideal climate for your plant: high humidity of the air, and a very draining soil, which does not excessively retain humidity. The presence of fungi in the soil is directly related to the presence of fungi around the plant, and also to a probable fungal disease, at the roots, or at the base of the stem. Mushrooms generally tend to prefer very wet soils, which do not have the possibility of drying out, but which remain soaked. If your plant is in good health, you should still try to get rid of the fungi in your pot, because they can at any time try to parasitize the roots, leaves and stem; try to think of edible mushrooms: tacks are the external manifestation of a disease of the roots and stems of trees that are already dying or have been cut down: over the years, tacks can also kill a tree due to their presence in the ground . Where do the mushrooms in your pot come from? Mushrooms produce spores similar to fine dust, which travel carried by wind or water. It is sufficient for a nearby plant to be affected by a fungus, or that you have repotted the stromanthe with soil that has remained in the sack for a long time, or you have the plant on the terrace and some neighbors have plants affected by fungi; it is not easy to understand where a mushroom comes from, but it is easy and important to eradicate it, or we risk ruining our crops. First of all it is advisable to repot your stromanthe, because we cannot know how the mushrooms have penetrated the soil; then, extract the stromanthe from the pot, and prepare a soil consisting of a part of new, fresh and rich universal soil, and a part of perlite or pumice stone, so as to constitute a soft and very well drained substratum; gently clean the roots of the stromanthe from the soil that covers them, and if necessary cut the roots that appear ruined or soft, using a very well sharpened scissor. At this point place the plant in the vase and the soil is well controlled. The soil you use must be new and fresh, and if you intend to reuse the old pot, before reintroducing the plant, wash it thoroughly, brushing it and disinfecting it with bleach, which you will then need to rinse thoroughly. Now that the plant is repotted, water the soil well, and spray the leaves with a systemic fungicide, which is a fungicide that can be absorbed by the leaves, to enter the whole plant in a circle. I remind you that stromantas love a very humid climate; this does not mean that they have to live in a soil that is always wet, it is enough to water them when the soil is well dried (avoiding to keep the substratum soaked with water) and frequently vaporize the foliage with demineralized water.
