Cymbidium orchids are very much the most popular choice by many people around the world but involve the same level of commitment that all orchids demand. Most people fail in maintaining them because of the misconception that they are easy to care for, forgetting the fact is that they remain very delicate. It is important therefore that you are informed on the proper care tips and the common problems that may hinder proper growth so as to preserve their beauty and health.
A pretty common problem is cymbidium orchid leaves falling off after turning brown or yellow. It is similarly easy to deal with. The understanding that cymbidium orchids have a single blooming season every year is important for determining the appropriate flowering pattern of the plant. Normal growth will result in healthy plant organs such as waxy petals and strong leaves. When the leaves start to turn yellow, the most common indication is that they are lacking some vital elements and in most cases will end up falling off. There are two possible cases that can affect a cymbidium’s growth, and they pertain to the environment or diseases.
The environment of the orchid is usually defined by the grower and is the easiest to work on so that the plant is restored to its healthy state. Cymbidium orchids mostly do well in plenty of sunlight and this is a requirement that can be hard to maintain in office or home settings. It is important also to realize that just like other orchids cymbidiums are sensitive to the excess light and will therefore turn color in both extreme and below average light environments.
Other than light, the temperature conditions of the plants need to be kept at optimum levels such that the air does not lose its moisture holding capacity. Low temperatures can therefore be the main cause for leaves turning colors due to the reduced level of humidity.
If you feel that you have sustained a fulfilling environment for your orchid but it still experiences leaf browning, then you may have to consider treating it for infections. One of the most detrimental viral diseases that affect cymbidium orchids is Bar Mottle, which results in yellowing of their leaves. It is characterized by a distinguished yellowing pattern such that leaves turn yellow in streaks as the virus spreads.
The virus more often affects the petals and results in their fall or stunting of growth, which is never a good sign for the plant. The only way to deal with this disease is to eliminate the plant or amputate the affected part, so long as the virus does not get a means to spread.
When watering the plant, it is important to realize that it is a natural epiphyte and will therefore need proper aeration and draining. The best environment therefore will have to be wood chip material or perlite which allows for effective drainage. It is also important to ensure that it is watered at least once every week to keep its water content at a suitable average.
These are all good places to start when you have leaves browning or falling off of your cymbidium. Try adjusting one thing at a time until you find the thing that makes a difference. We wish you good luck and happy growing!
