- Why the leaves of orchids turn yellow? There are important orchids care tips for orchids beginners. Let's analyze and from a biological point of view, try to answer the question of why the leaves of orchids turn yellow. Lean more about orchids plants biology and nature facts. There are not so many reasons causing yellowing of the leaves.
The color of the leaves is given by the photosynthetic pigment chlorophyll contained in the chloroplasts, which is what makes the leaves green and the color change occurs when, for some reason, chlorophyll is destroyed and disappearing and then other pigment substances contained in the chromoplasts and chloroplasts of cells become visible orange carotenoids, yellow xanthophylls, red anthocyanins and the leaf turn yellow!. But what causes the destruction of chlorophyll in chloroplasts? Yes, the same reasons that prevent the normal course of photosynthesis and there are several of them.The main reason and the most common is the natural aging process. An adult orchid 3 years and older can naturally shed one or two lowest leaves per year. the same thing happens with autumn leaves, when naturally orchid leaves turn yellow and fall off. Another common cause of yellow leaves is salinization of the substrate and orchid roots. If the orchid is a healthy plant and has light green or yellow leaves, this may mean a violation of salt metabolism. The next reason for the yellowish tint of the leaves is the lack of light. As already mentioned, the more intense the plant receives ultraviolet light, the more intense the green color and vice versa. If the orchid is far from the window, you need to add artificial lighting. #orchidsneverdie #orchidaceae #orchidrepotting #orchidroots #orchidspecies #wateringplants #growingorchids #terrarium #orchids #OrchidsForBeginners #OrchidsCare #phalaenopsis #PhalaenopsisOrchids

This was very valuable. So thank you very much for explaining this in very well versed words. I now can understand my beautiful plant well.
Super helpful, super interesting video. I feel like I understand my orchids far better as a result - thank you!
I love your passion for this! So cool. Are you in south Florida growing these orchids? Very impressed by you
Brilliant. Great knowledge. Thank you for sharing x
Открыла ради интереса. Какой приятный английский! Радость для ушей😊
Nice berry
Thank you for the wonderful explanation. What to do when the leaves lighten due to over absorption of chemical from the tap water? Now I use soft water but the leaves are already much lighter. Can the orchid be saved?
wow great video
My orchids always turn yellow after repotting. I use moss and bark mix and other things in the past but they always turn yellow and in some cases they die. Can you help?
So good!!! What a great explanation.
Hmm very interesting, nice
If the astronauts can only fart then yeah they're stuck on earth
What do l do with the flowers of the orchid start drooping?
They were doing so nicely when I took them out of the store plastic pot , they were breathing. Yes, but I think they’ve reached their time .
Do l remove the flower?
I received 2x orchards. One is doing great sitting under cover, on an outside table, with filtered light. The other, was placed in a greenery where it got direct morning light which burnt the main body on one side & got some extra water drips from above plants in excessive rain. It now seems the dead new leaves died from the excessive sun damage. I did everything I found on YT channels but the plant has now lost all leaves while the other, which live over an hour away, is thriving in almost similar conditions.
What the hell is going on?
Some say the sun killed it, which looks right & your sight recommends sunlight, it’s very confusing.
Normally sun damage occurs when plant just brought out from greenhouse, but sun damage not dangerous for orchids and healing fast, when plant develops resistant to ultraviolet over the time. I think it was something else, excessive rain water maybe. I have orchids plant growing in the places with direct sun exposure and thriving.
How often do you suggest watering I'm in South Africa
Thank you for info I donot like my flowers to die so I will take care of it my sister gave to me I need to save.it
Thank you! I didn't realize one of my orchids was waterlogged and all it's leaves turned yellow and fell off, is there any hope to grow new leaves or just toss it?
Dry it out first, then if your orchid have some healthy roots left, that a good chance to save it , watch our video: ua-cam.com/video/8XgOQQDwJR4/v-deo.html

The curly cresent? Didn't you see the volcano? If the crust of the mantle starts cracking then volcanoes can be anywhere in the world
👍
You said yellow leaves don’t need to be cut off, then cut it off.
If you listen again she clarifies by saying that you can cut yellowing leaf off after it has turned completely yellow .
