Reviving wilting Spathiphyllum with a cucumber slice test: a gardener's trick

Most of us might have wondered why the Spathiphyllum yellows and wilts at an alarming rate. There could be several reasons contributing to the poor condition of such a plant. Factors, particularly injurious to the Spathiphyllum, include dry air during winter, inadequate exposure to daylight, and poor room ventilation. Such conditions provide a hospitable environment for diseases or pests to infest our Spathiphyllum. If you notice such a scenario, just grab a slice of cucumber, and you'll quickly diagnose the problem of the wilting Spathiphyllum.

The Spathiphyllum requires a substantial amount of light, but direct sunlight can cause enduring damage to its delicate and long leaves. To ensure optimal growth, it is best to place it near an east or west window behind a curtain. This is particularly imperative during seasons when the Spathiphyllum is prone to yellowing and wilting, and lack of light only aggravates the situation. Plant enthusiasts know well that Spathiphyllums are extremely delicate potted plants, which can quickly become "offended" if not appropriately cared for.

Important for their cultivation is the temperature; these plants prefer warmth. A minimum of 18 degrees Celsius during winter is sufficient for Spathiphyllums to grow healthily and lushly. They should not be exposed to drafts as cold air causes them to wilt. Similarly important in the care of Spathiphyllums is maintaining proper humidity. It is highly recommended to spray them with water and limit watering to deter fungal diseases and pests attracted to moisture in their pots.

It can be challenging to detect with just the naked eye if our Spathiphyllum is hosting small unwelcome guests, most commonly earthworms and nematodes, which pervasively spread on the leaves and in the pot of the plant. This infestation can lead to the yellowing and wilting of the Spathiphyllum and hinder growth. But, worry not; a simple "cucumber slice test" can help determine its condition and reveal possible pests.

For this, a slice of fresh cucumber or another vegetable with a strong aroma comes in handy. Simply place it into the Spathiphyllum pot for 24 hours, then examine the results. If the cucumber slice is showing signs of damage, including dark lines or spots, it’s likely your Spathiphyllum is infested with pests. At this stage, it is recommended to put the plant into quarantine and replace its substrate to bring it back to health.
