How to find out the cause of Anthurium andraeanum flower heart blackening? symptomatic nursing.

Red Anthurium, unexpectedly the stamens turn black, really spoil the scenery. I believe that many friends who grow andrographis andraeanum will be particularly worried about this situation: what is the reason why the anthurium flower heart turns black? This article intends to make a brief introduction to the reasons why the heart of Anthurium andraeanum turns black.

Anthurium andraeanum, also known as Anthurium andraeanum Linden, Araceae perennial evergreen herbs. Stem nodes short; leaves arising from base, green, leathery, entire, oblong-cordate or ovoid. Petiole slender, spawn flat, leathery and waxy luster, orange or scarlet; fleshy inflorescences yellow, but blossoming all the year round.

However, such a beautiful flower has black spots in its stamens, which cannot help but make people feel sad. So why did this happen?

According to reports, Anthurium andraeanum may turn black for two reasons:

One is the need of metabolism. Generally speaking, Anthurium andraeanum bloom for a long time, only then will the anthurium flower heart turn black. This situation is caused by the natural law of blooming and shedding, and because it is not a disease, it is generally not necessary to care too much about it.

Second, it is caused by watering too many rotten roots. The cultivation substrate of Anthurium andraeanum is generally imported peat, which has a strong ability to preserve fertilizer and water, but it is not easy to absorb water after it is dry, so it should be watered immediately when it is slightly moist, and cannot be watered after it is dry or wet. The peat on the surface layer is a sign of watering. If there is too much water content in the matrix, if there is no dry or wet watering, it is easy to cause root rot and lead to poor growth of the whole plant.

At the same time, because Anthurium andraeanum is difficult to absorb general chemical fertilizers, it is better to use fully water-soluble fertilizers such as' Huaduoduo', and the amount of fertilizer should not be too large. It is not a principle to apply light fertilizer frequently, excessive absorption of plants will cause fertilizer damage, leaves blacken and wilt, and plants die.

It can be seen that the heart of Anthurium andraeanum turns black, excluding the reason that the flowering period is too long, mostly because of too much watering, especially at low temperature. Although the high temperature and humidity environment is conducive to the growth of Anthurium andraeanum, but the water of plants in the indoor environment is often not easy to evaporate, if too much water will inevitably lead to rotten roots, too much water will cause the flower heart to turn black.
