It’s a common question asked by orchid growers, and unfortunately, there isn’t always a straightforward answer. Depending on the type of orchid and the specific circumstances, there can be several reasons why leaves might turn yellow.
In general, though, yellow leaves are most often caused by either too much or too little water. If your orchid is getting too much water, the leaves will start to yellow and drop off. If it’s not getting enough water, the leaves will also turn yellow, but they will usually get wrinkled and dry-looking first.
Other possible causes of yellowing leaves include excessive sunlight or heat, nutrient deficiencies, pests, or diseases. If you’re not sure what’s causing the problem, it’s always a good idea to consult with a professional at a nursery or garden care company.
Fortunately, in most cases, yellowing leaves can be easily fixed with some simple adjustments to your care routine. With a little trial and error, you should be able to figure out what your orchid needs to stay healthy and happy!
