Spathiphyllum, or Spathiphyllum, from the Aroid family, is well known to amateur gardeners as a beautiful decorative houseplant, which has earned very wide popularity due to its surprisingly beautiful, unusual flowers. With insufficiently proper care, the leaves and flowers of spathiphyllum begin to blacken, and other changes in the appearance of indoor culture also occur.
Why tips and edges of leaves turn black
The notorious, ubiquitous problem of this decorative plant, well-known in indoor floriculture, is the appearance of dried and blackened leaf tips, which greatly spoil the appearance of the culture. To avoid this, you need to know the causes of this phenomenon and exclude them:
- the main rule of care for spathiphyllums is the presence of high humidity, so overdrying often becomes the main cause of discoloration of the ends of leaves;
- improper arrangement of the indoor flower can also be a factor causing darkening of the leaves;
- leaf tips may turn black due to a lack of phosphorus-potash or nitrogen-containing fertilizers.
It is for this reason that it is very important to observe not only the temperature regime, but also to adhere to optimal humidity indicators in a room growing a decorative room culture. The most comfortable are the following conditions for growing spathiphyllum in indoor floriculture:
- the upper part of the soil mixture must be sure to dry before the next watering;
- at the stage of active growth of the plant (from about the end of February to September), the plant needs to be fed with full complex fertilizer in a weak concentration;
- periodically, transplantation of an adult room culture with a complete replacement of the soil should be carried out;
- the heat-loving indoor plant Spathiphyllum perfectly develops and grows with humidified air and a temperature of 20–23 ° C, but the presence of direct sunlight can be detrimental to indoor decorative culture.
From time to time, it is advisable to provide the Spathiphyllum indoor flower with a warm, refreshing shower. However, it must be remembered that excessively hard watering causes rhizome decay, which is also characterized by the appearance of black tips on the leaves. The solution to this common problem is quite simple and consists in regulating the water supply of indoor spathiphyllum.

Why do spots appear
In some cases, spathiphyllum not only dries the leaves along the edges, but also appears characteristic drying black spots in the central part of the leaf plates. Usually, dark brown or black spots on the spathiphyllum may indicate excessive watering, which accompany a houseplant for quite a long time. In this case, the root system of ornamental culture quickly begins to rot, which causes blackening of the leaves.
As a result of a burn of the root system with fertilizers, extensive dark spots appear on the leaves of the spathiphyllum very quickly. Then the leaves turn yellow and die off. To correct this situation, it is enough to rinse the root system of the plant in clean and warm, decanted water, and then transplant it into a clean soil substrate.
The flower turns black in the case of the so-called "wet" hypothermia, which accompanies evening watering followed by freezing the root system on a cold windowsill. In this case, it is recommended to warm the window sill or place a flower pot at a certain distance from the window in the winter. With strong freezing of the roots, it is quite difficult to save an indoor plant. A good effect has an increase in the immunity of the decorative culture and pouring warm water through the pan with the addition of Kornevin.
Causes of blackening of flowers
The flowers of spathiphyllum are very attractive, and the abundant bloom makes this indoor culture very decorative. Spathiphyllum has a very high level of sensitivity to waterlogging of the soil, and if this happens, the cores blacken and the flowers darken.
Insufficient soil moisture during the cultivation of "female happiness" (so-called spathiphyllum) is also very difficult to tolerate by the plant and negatively affects the appearance of the flowers. The plant needs almost constant and regular spraying of the leaves, but moisture must not be allowed to enter the flowers themselves.
Disease Prevention and Treatment
As a rule, if the cultivation technology is followed and the plant is provided with proper care, diseases and pests of spathiphyllum practically do not affect. Nonetheless, special attention should be paid to indoor flower in the following cases:
- a rather common pest of Spathiphyllum is a mealybug, to destroy which it is necessary to wipe the leaves with a weak alcohol solution, and then spray with infusion based on citrus peels or “Actellik”;
- defeat with a sooty fungus is accompanied by blackening of the leaves of spathiphyllum, and treatment is used to treat the affected surfaces with a standard soap solution;
- significant damage to the flower can be caused by shield moth, which provokes the appearance of dark spots on an indoor plant, and to combat which a soap-tobacco solution or treatment of the aerial part with nicotine sulfate is used, at the rate of 1 g of the drug per 1 liter of warm water.
The best way to prevent Spathiphyllum from being damaged by pests or diseases is still to systematically wipe the leaves with a damp sponge.

When growing spathiphyllum, one should take into account the fact that foliage grows better in too large pots near an indoor plant, and to obtain abundant and prolonged flowering, it is imperative to observe a proportion between the size of the root system and the diameter of the planting capacity.
