Low Temperature

When taking care of stromanthe triostar in winter, especially in the north, if the temperature is lower than 10 ℃, Stromanthe Triostar is very prone to frostbite. The first manifestation is that Stromanthe Triostar leaves are tender yellow and dry, and the leaves will dry up over time. This is because the temperature is too low.

Low Humidity

Stromanthe Triostar is a kind of plant that likes humidity. The humidity of family maintenance should reach 60%. If it is placed in a relatively dry environment for a long time, the new leaves will dry and the old leaves will be sharp.

Excessive Fertilization

When taking care of Stromanthe Triostar, if the fertilization is too thick or raw fertilizer is applied, it will cause root burning and cause the leaf tips of Stromanthe Triostar to turn yellow and dry. In the later stage, the fertilizer with thin concentration should be selected instead of thick fertilizer. Once the fertilization is too much, it needs to be watered immediately to dilute the fertilizer.

Root Rot

Soil discomfort and excessive watering can easily lead to the root rot of Stromanthe Triostar, which can not normally transport water and nutrients, resulting in the lack of nutrients in the leaves, which becomes dim and yellow and reduces the ornamental value. At this time, it needs to be removed from the pot, trimmed and repotted. (Read More: Calathea Triostar vs Stromanthe)

If the root system is healthy, it can be maintained.
