How to Deal with Yellowing and Blackening Leaves on Gloxinia? Detailed Solutions
Gloxinia (Sinningia speciosa) is a potted plant. Because its flowers are relatively large and pink in color, many flower lovers grow gloxinia at home, placing it in places like the living room or balcony. You may encounter some problems during the growing process, such as leaves suddenly turning black or yellowing. So in this chapter, the editor will specifically explain this problem to everyone. Let's take a look together below!
I. What to Do When Gloxinia Turns Black and Yellow
1. Water Properly
Gloxinia is a relatively drought-tolerant plant, so there is no need to water it every day. Be careful to water as little as possible, and follow the rule of not watering until the soil is dry. Also, correct a certain view - this is also a compulsion many people have - do not assume the plant is short of water or dry just because the soil surface looks white. Actually, that is not the case. If you scrape away the top layer, you will find it is wet inside. In addition, when the winter temperature drops to a certain level, gloxinia enters a dormant period. Once it enters dormancy, you do not need to water it at all; watering once every month or two is no problem. Do not water the leaves directly, because the fine hairs on its leaves will develop water spots when they touch water, causing the gloxinia leaves to rot.
2. Absorb Enough Diffused Light
For a potted flowering plant like gloxinia, do not expose it to direct strong light. It is best to place it in a spot with diffused light. Of course, this applies when it is in the mature flowering stage. If it is in the seedling stage, then in winter it should receive plenty of sunlight, some direct light and diffused light.
3. Clean the Leaves After Fertilizing
Many of us have this habit of paying no attention after fertilizing, but this is actually very wrong. If fertilizer that has not been fully absorbed remains on the leaves, it will cause the leaves to rot. So after fertilizing, we must be sure to rinse the leaves clean with clear water.
II. What to Do When Gloxinia Drops Leaves
Leaf drop in gloxinia is generally related to watering; other factors will not cause it to drop leaves. When watering gloxinia, be careful not to water directly onto the leaves, as this will damage the leaves, and over time will cause the leaves to fall. When watering, also maintain air humidity. It is best to water by spraying a fine mist, and also spray water around the pot.
The above are the solutions for yellowing and blackening leaves on gloxinia. Because gloxinia has fairly good drought tolerance, everyone must pay attention when watering. Also, there is fertilizing: fertilizer will react with the air, so it will rot the leaves, causing them to turn black and yellow, or even fall off.
