Phalaenopsis Orchid Troubleshooting


Phalaenopsis Orchid Leaves Turning Yellow

There are 3 main reasons for yellow leaves on an orchid – too much light, wrong temperature, and disease.

First, make sure that your orchid is not getting too much light. Move it to a different room with less sunlight.

Second, check the temperature requirements of the plant labeled on its pot/labeling tags to ensure it has been kept at the correct temperature at all times.

Finally, there are many diseases that can cause yellowing leaves so if you suspect this is what may be causing the problem contact an experienced horticulturalist who will be more than happy to help diagnose any problems and advise on treatment plans accordingly.


Phalaenopsis Orchid Leaves Turning Yellow and Falling Off

A Phalaenopsis orchid will sporadically drop leaves because old leaves will naturally turn yellow and fall off. That being said, the plant should still have new leaves coming in to replace them which are green in color.

If you have an older plant where this is not happening, it could be because the potting soil does not have enough nutrients in it and you should give it a good dose of urea-free fertilizer.

If this continues to happen then you might need to repot your orchid into fresh orchid potting mix that has some slow-release fertilizer mixed into it.


Phalaenopsis Orchid Leaves Splitting

Phalaenopsis orchid leaves splitting often signifies a combination of issues, such as a lack of water, insufficient humidity, excessive sunlight exposure, and physical damage.


Phalaenopsis Orchid Leaves Drooping

Drooping leaves usually result from a lack of water. So first check to make sure the plant is getting enough water and/or use a liquid fertilizer every other week on a well-drained orchid potting mix.

It’s also possible that the orchid has root rot, which can happen if you overwater your plant. This can lead to a fungal infection that can damage your orchid’s roots to the point where they can no longer absorb water.


Phalaenopsis Orchid Leaves Turning Black

The most likely cause of orchid leaves turning black is black rot, which is caused by two distinct fungi, Pythium ultimum or Phytophthora cactorum. The upper leaf surfaces turn black with patches of the leaves becoming red-brownish in color with dark brown to black lesions spreading on the surface.


Phalaenopsis Orchid Leaves Turning Purple

Why are my Phalaenopsis orchid leaves turning purple? This can be due to a phosphorus deficiency, which you would want to address by feeding the plant an appropriate fertilizer and ensuring that soil moisture is sufficient. Purple leaves could also signal root rot, so check growing media for any signs of decay / waterlogged/soft areas.


Phalaenopsis Orchid Not Blooming

A Phalaenopsis orchid not blooming can be a difficult problem to diagnose. There are many causes, some of which include applying the incorrect amount of water, lighting requirements (not enough or too much light), and nutrient requirements (lack of phosphorus.)
