Two reasons for yellowing leaves at the base of Dendrobium orchids and how to fix them

The picture below shows a flower lover's Dendrobium orchid, asking why the leaves are turning yellow. Xiao Qi took a look at your picture and won't go through all the possible reasons for yellowing in Dendrobium orchids one by one; instead, I'll get straight to what's causing it in your plant.

The stems at the base of your Dendrobium orchid have wrinkled and shrunk, and you can clearly see that you planted it in bark, and the bark is very dry and drains extremely well. The ceramic pot itself also drains quite well. You didn't water it, and the lack of water is causing the leaves at the base to turn yellow and gradually drop off. Dendrobium is an epiphytic plant; it likes a humid environment and soil, and on the premise that the soil drains well and has good air permeability, you must keep the potting soil moist and also regularly raise the air humidity for it. Only then can you grow it well without yellow leaves appearing. Since you're growing it in a ceramic pot, and ceramic pots drain very strongly, you must keep the potting soil moist for it to grow well. Lack of water is one reason for the yellow leaves at its base.

Another reason is that it lacks fertilizer. Dendrobium orchids grow in this season, and yours is also blooming, and blooming consumes a large amount of nutrients, so you must replenish fertilizer for it in time. After it finishes blooming, cut off the flower stems and give it a multi-element mixed fertilizer to replenish. Let the nutrients consumed by blooming be fully restored. This flower is almost done blooming; once it finishes, cut it off in time and give it some fertilizer. Then it can recover very quickly.

There are only these two reasons causing the yellow leaves on your pot of Dendrobium orchid. Water it in time, and after it finishes blooming, replenish fertilizer in time, and it will recover very quickly. You can go ahead and follow what Xiao Qi said.
