Why do leaves of spathiphyllum dry?
One of the most unpretentious and decorative houseplants of spathiphyllum can be grown even by inexperienced gardeners. It blooms better in shading, loves plentiful watering and is able to forgive almost any misses. Problems with spathiphyllum rarely occur, and always - only with serious violations of care. Most often, the plants simply dry out and the leaves turn yellow. If the conditions are adjusted in time, the bushes are restored very quickly and delight with even more beautiful greenery.
In spathiphyllum, drying is always accompanied by a bright yellowing or blackening: if this plant decided to attract attention, then by all means at once. The signs accompanying drying out are usually oriented.
Leaf tips dry
“Standard” for any moisture-loving plant, the drying of the tips of the leaves in an insufficiently humid environment in spathiphyllum manifests itself as a dry, dark spot on the point itself. Most often, it almost does not affect the main leaf blade, not so much affecting the decorative effect.
So spathiphyllum reacts to extremely dry air (in general, the plant tolerates the usual average conditions of living rooms much better than competitors), but not only. The tips of the leaves of spathiphyllum can dry out even with unstable, constantly changing humidity of the air or soil.
It is difficult to avoid drying out the ends of the leaves without measures for installing any kind of humidifiers and creating stable moisture; it can occur even with frequent spraying.
It is easy to prevent the phenomenon: in rooms with dry air and working air conditioners or heating systems, it is enough to install plates and pallets with wet materials nearby. You can group plants with moisture-loving colleagues around moisturizers and conduct more frequent showering.
An important role is played by other measures:
- hygiene, prevention of dust accumulation on the leaves of spathiphyllum;
- protection of spathiphyllum from direct proximity to heating appliances.
"Black" drying of leaves
This is a strong drying of the blackened leaves, starting from the tips and spreading farther with time. When the upper part of the leaves is blackened, drying covers a much larger area, most often the leaf plates are gradually deformed, and where healthy tissues are preserved, the leaf turns yellow unevenly.
This type of drying in spathiphyllum causes systemic waterlogging and rotting of the roots. More often the problem manifests itself in the fall and winter. At the initial stage, it is enough to adjust the watering, dry and loosen the substrate.
If the soil becomes very acidic, an unpleasant odor appears and the plant is in a very depressed state, only an emergency transplant with root treatment and removal of affected tissues will help save the spathiphyllum.
"Black" drying may indicate too generous feeding. If there are no signs of waterlogging, the small tips of the leaves turn black, then it is enough to stop feeding or change the concentration of fertilizers.
Spatifillum leaf stains
The appearance of uneven dry brown spots on the leaves, asymmetric (mosaic) drying of the edges of the leaves, lethargy, especially in large-leaved varieties, can also be solved by correction of care.
Sunburns are a typical reaction of spathiphyllum to too bright lighting with sunlight on sensitive leaves. It appears in large, dry, unevenly scattered spots. There is only one way to deal with the problem - by moving to a new place with diffused lighting or installing a screen.
Drying yellowed leaves
Drying of the leaves, which begins after or simultaneously with their yellowing, indicates insufficient watering and frequent strong drying of the substrate. Spathiphyllum does not respond very well to droughts: if the substrate dries out completely, the leaves wither, lose turgor, but only the tips dry and the plant is restored.
If the leaves turn yellow, this is a sign of systemic disorders. Trying to restore the plant, do not resort to too abundant watering. The best strategy is to make watering more frequent and gradually restore normal average humidity.
Spathiphyllums dry out old leaves and respond to a lack of space for the development of roots. If the capacity is too small, the roots are completely filled with an earthen lump, especially with the formation of a large number of daughter sockets, the spathiphyllum begins to age faster, the oldest lower sheets quickly turn yellow and dry.
To stop this process, it is enough to transplant according to all the rules, for large groups - with separation. It should be borne in mind that such dropping of old leaves can be a sign of preparation for flowering or “saving” of resources when flowering is too long.
This can be a natural process, so you should always check the degree of filling the pot with roots and only then proceed with the transplant.
Drying of unblown young leaves
The drying of young leaves of spathiphyllum, often before they even unwind, supplemented by quick drying and blackening of the tips of old leaves can occur on recently transplanted, acquired, rearranged and weakened plants and with:
- too abundant watering, in which the substrate is in a constantly wet state;
- often repeated droughts, complete drying of the substrate;
- critically dry air in combination with any disturbance in watering;
- lack of top dressing;
- lack of a specific macroelement - phosphorus or nitrogen - due to improper selection of fertilizer composition.
What does spathiphyllum want?
Spatiphyllum “earned” the glory of a simple-growing plant. In order to avoid problems, it is enough to take care of several points in the cultivation:
- choose a bright or semi-shaded place with diffused lighting, many spathiphyllum grow well even in the shade;
- monitor the temperature, the values of which, even in winter, should not fall below 16 degrees;
- protect spathiphyllum from drafts, the proximity of heating appliances and pot overcooling;
- to maintain stable light moisture of the substrate with restrained, gentle irrigation, do not allow water to stagnate in pallets and always allow the soil to dry in the upper layer;
- provide at least average humidity;
- carry out regular showering and clean leaves from dust;
- rotate the plant in relation to the light source;
- fertilize from March to October with special fertilizers for ornamental and deciduous plants every 2 weeks, but reducing the standard dosage. If the spathiphyllum continues flowering and growth in the winter, it is worthwhile to reduce the nutrition, but not to stop them;
- carry out transplantation only as necessary, in a high-quality loose substrate.

In order to never encounter the problem of drying leaves of spathiphyllum, you just need to remember the golden rule of growing them - the more stable the environment, the more decorative and plant.
