What to Do When Dragon's Tongue Orchid Leaves Turn Yellow? The Causes and Solutions Are All Here
1. Too Little Light
In fact, too little light doesn't just turn the leaves yellow; it also makes them thinner and thinner, and brittle, looking completely lifeless. If there is no ample sunlight for a long time, it will also easily grow leggy, becoming more and more sparse, and the leaf color will become paler and paler.
Solution: Except at midday, it is best to place it in the sunlight at other times, because the sunlight at midday is too strong and it may not be able to tolerate it. However, if the leggy growth is quite severe, you can do some appropriate pruning so that the nutrients are concentrated.
2. Temperature Too Low
It is winter right now, and many friends' dragon's tongue orchids have developed yellowing leaves. Yesterday a friend even asked me: I only have one radiator at home, and at night when the temperature is at its lowest it can drop to 6 degrees - is this the reason its leaves are turning yellow? That's right, the excessively low temperatures at the end of the year easily make its leaves turn yellow.
Solution: At this point, do not move it directly to a very warm place; raise the temperature little by little. Otherwise the plant cannot immediately adapt to such a rapid change in environment, and other problems will appear. By the way, this plant is suited to living in temperatures above 20 degrees, and in winter the temperature should at least be kept above 10 degrees, otherwise yellow leaves are a matter of minutes.
3. Other Reasons
So-called other reasons include pests and diseases and the plant's natural metabolism, etc.
Solution: For metabolism, you can do some appropriate pruning; if it is sick, you can treat it with specialized medication.
