What to Do When Selaginella uncinata Leaves Turn Dry and Yellow? Causes and Solutions

Does the name Selaginella uncinata give you the feeling of an immortal herb? This Selaginella uncinata is generally little known; its appearance looks dainty and exquisite, and it is a foliage plant with good ornamental value, a fine potted specimen. So if its leaves turn dry and yellow, what should be done? Next, Shuanshuai will talk about the causes of yellowing leaves in Selaginella uncinata and the solutions!

1. Watering too frequently

Watering has always been a difficult task for most growers 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, the leaves lack nutrients, so 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 forcefully; water slowly in a buffered way, and wait for the water to penetrate 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 the leaves turn yellow, then they wither. After winter passes, new plants will grow again. At this time, clean up the dead plants and do the sanitation work well. The reason leaves easily turn yellow in winter is 80% due to low temperatures. Then there is the fact that many people like to keep it on a balcony windowsill. The temperature difference between night and day is very large, and plants are easily damaged in an environment with such a big day-night temperature difference, which may also cause the leaves to turn yellow. Some warming measures can be taken, such as covering the surface with a layer of cotton at night.

3. Too strong light

The leaves of Selaginella uncinata are very delicate and fragile. In summer, when no one tends to them, water evaporates very quickly. Moreover, potted plants like this are generally placed on balconies, almost in direct sunlight. We should take some shading measures to reduce the amount of water evaporation and prevent the leaves from lacking water and becoming shriveled.

4. Root rot

This cause also occurs often, 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 lack nutrients and turn yellow. 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 then we will see dry and yellow leaves. Therefore, when growing it, be sure to remember to turn the soil regularly to check whether the roots have rotted. Once they have rotted, cut them off promptly, then wash them clean, replace the soil as well, and use new soil.

The above are the causes of dry and yellow leaves in Selaginella uncinata and the solutions. Selaginella uncinata itself does not have thick leaves; its leaves are of the delicate and fragile kind. Usually, pay attention to the influence of external factors, and it is best to turn the soil regularly, because root rot cannot be seen and needs to be checked. Finally, I hope everyone can grow healthy Selaginella uncinata!
