What to Do When Selaginella uncinata Leaves Turn Dry and Yellow? Cause Analysis and Solutions
Does the name Selaginella uncinata give you the feeling of hearing about a magical herb? This Selaginella uncinata is generally little known; it looks delicate and dainty, is a foliage plant, has quite good ornamental value, and is a fine potted specimen. So what should you do if its leaves turn dry and yellow? Next, Shuashuai will explain the causes of yellowing leaves in Selaginella uncinata and the solutions!
1. Watering too frequently
For most growers, watering has always been a hard task to control well. When we water, we must never overwater, otherwise too much water will cause water to accumulate at the bottom of the pot, making the soil's air permeability worse and preventing the roots from breathing, which affects the roots' absorption of nutrients. In this way, if the leaves lack nutrients, how could they not turn yellow? When watering, do not rush to start; first observe whether the soil is dry and lacking water, and whether the plant is short of water, then water. When watering, try to choose a time when the temperature is high. During watering, do not pour violently; water slowly in a buffered way, and wait until the water has penetrated the pot before continuing. The water temperature should not be too low; keeping it consistent with room temperature is best.
2. Unreasonable temperature control
Yellowing leaves in Selaginella uncinata mostly occur in winter: first they turn yellow, then they wither. After winter is over, new plants will grow again. At this time, clear away the dead plants and do a good job of sanitation. The reason leaves easily turn yellow in winter is 80% due to low temperature. Then there is the fact that many people like to place it on balcony windows to grow it. The temperature at night differs greatly from that in the daytime, and plants are very easily injured in an environment with such a large temperature difference between day and night, which may also cause the leaves to turn yellow. Some warming measures can be taken, such as covering its surface with a layer of cotton at night.
3. Too much light
The leaves of Selaginella uncinata are very delicate and fragile. In summer, when no one tends to it, water evaporates very quickly. Moreover, potted plants like this are generally placed on balconies, almost in a state of direct sunlight. We need to take some shading measures to reduce the amount of water evaporation and prevent the leaves from becoming shriveled due to lack of water.
4. Root rot
This cause also often appears, because if you are not a professional flower grower, you generally will not check every day. Once the roots rot, many bacteria will breed and invade the plant, making the roots unable to absorb nutrients, so the leaves will turn yellow from lack of nutrients. Also, because most of the water comes from absorption by the roots, once the roots rot, water absorption and transport will also have problems, so the leaves will become shriveled, and that is why we see dry and yellow leaves. Therefore, when growing it, be sure to remember to regularly turn the soil to check whether the roots are rotten. Once they are rotten, cut them off promptly, then wash them clean, replace the soil accordingly, and use new soil.
The above are the causes of dry and yellow leaves in Selaginella uncinata and the solutions. Selaginella uncinata itself is not the kind with very thick leaves; its leaves are the delicate and fragile kind. Usually, pay attention to the influence of external factors, and it is best to regularly turn the soil, because root rot cannot be seen and needs to be checked. Finally, I hope everyone can grow healthy Selaginella uncinata!
