Why leaves of spathiphyllum turn yellow
Spathiphyllum is an evergreen perennial growing in humid and marshy forests of a warm climate. In indoor conditions, this flower is not very demanding in care, but if small oversights are allowed, the grower will have to deal with problems such as yellow foliage and various pests. How to fix and prevent the occurrence of such problems will be described below.
Improper care or conditions
Often, an absolutely healthy spathiphyllum suddenly begins to turn yellow, or simply wither. Such a flower reaction may indicate a variety of hidden problems. Leave what happened without attention is impossible, since you can lose the plant. Therefore, the first thing you should do is to review the conditions of its detention, since not observing them is one of the most common causes of yellow foliage.
If in the room where spathiphyllum grows insufficient air humidity, then the tips of the leaves begin to turn yellow. Color changes only in a small part of the sheet (1-2 mm). The rest of the leaf plate remains a natural green color. A yellow line may appear in the border zone. If you do not take measures in time, then yellowness gradually turns into blackness and spreads over the entire sheet. He eventually dies.
Did you know? The genus of plants, spathiphyllum, got its name from the merger of the two Greek words σπάθη (bedspread) and φύλλον (leaf), since its bract petal looks like a bedspread.
Spathiphyllum loves light very much, but if the sun's rays fall on its leaves, they will leave burns. They look like spots or stripes with a yellow tint and with a thinned surface.
In bright light, the color of the sheet plate will gradually change: from saturated green to yellowish-green, which can completely turn into colorless.
Such a plant urgently needs to be rearranged to another place or on the old one to create a shadow, or move away from the window. If possible, it should be placed on the north, northeast, northwest or east windows.
When a plant lacks nutrients, its foliage begins to change color unevenly. Most often, this color resembles a mosaic: green spots are scattered on a yellow background, or vice versa. The veins may also lose color or only they will retain their natural shade. Most often, this indicates a lack of elements such as boron, calcium, iron.
To correct the situation you need:
- change the soil in the pot to light, loose and slightly acidic;
- spray the flower with iron chelate (if the vein has changed color) or feed it with a mineral complex (in other cases);
- 2-3 weeks after transplantation to introduce complex fertilizers;
- water the flower with warm soft water and spray twice a day.
Important! Most often, spathiphyllum lacks nutrients during flowering, as this period is quite long and energy-intensive. Therefore, a flowering plant should be regularly fed.
With improper watering, the plant may experience both excess moisture and its lack. In the first version, the leaves begin to dry and blacken in large pieces. It can be just brown or black spots or discoloration of the tip of the foliage. Such changes appear due to the fact that the root system constantly locks. Reduce watering so that the soil dries well, then water only when the topsoil dries to 1 / 3-1 / 4 of the depth. If the spots continue to spread, then most likely the root system has already begun to rot.
If the spathiphyllum experiences a lack of moisture, but its leaves begin to fade, and if you do not water it in time, then it will turn yellow. Drought is less dangerous for a flower than waterlogging, but it is often not recommended to arrange it for a long time. Noticing that the plant has wilted, it needs to be watered. If, after a few hours, the leaves did not become hard, then the soil is probably very dry or there is a lot of peat in it, then you need to place the flower pot in a container with water so that its root system draws moisture from below. It will be enough to hold so spathiphyllum for 15-20 minutes.
The plant reacts to drafts or low temperatures by changing the color of the foliage (the appearance of a yellow tint along the edge). There may be another variant of the reaction to cold - blackening of leaf plates.
A plant transplant is needed in order for the overgrown root system to receive enough nutrients. If the roots completely fill the pot and begin to fall out of it, then the flower has nowhere to get nutrients from, as the soil is already depleted and it slowly begins to die.
