    Default Phalaenopsis bud blast issues

    My phalaenopsis is going through a bud blast... I believe the issue was overwatering at first but now I‘m unsure. Many of the unopened buds are turning yellow except for a select few. I don't know if I'm supposed to let the yellowed ones fall off by themselves or cut them off. I'm also worried the apparently unaffected buds will start turning yellow as well. I keep the orchid near a window, but I usually don't allow sunlight to touch it directly in fear it'll shrivel up. Instead, I have a curtain drawn over the window. It's not so thick that sunlight can't peek through the fabric, but it still keeps some of the brightness out if the sun‘s rays are very bright. Is this ok? Watering is only once a week with a large ice cube, and I usually touch the orchid moss at the top to see if it‘s moist. If it's still moist by the day i usually water, am i supposed to not water? I presume I overwatered last week because I used remaining water from a bottle of tap water instead of an ice cube. What can I do to fix the bud blast problem? I will be uploading photos later of what the plant looks like now.

    Hello from Colorado!


    First, please stop watering with an ice cube. Think about it. These are tropical plants that live in a forest, deep where it doesn't go below 60 F likely. Now you are putting frozen water on their roots. Also, don't let them sit in standing water. They need to drain. We are most successful growing orchids when we fool them to think they are still in nature.

    There are many reasons for bud blast. I usually just wait till they fall off in my fingers when it happens. I don't usually encounter bud blast unless it is on a 'new to my environment' orchid.

    It is best to look at the roots and see if they are green before you go and water the Phal. And if they are green, they don't need watering. The orchid is likely in a clear plastic pot of some sort. Do you know the state of your roots? Healthy roots are required for healthy orchids.

    Welcome from Florida.

    I would also tell you to stop using the ice cube! Water the plant when needed in the sink and water only the media so as to not get water into the crown which will cause bigger problems. Harvey is also right the color of the roots they will tell you when it is time to water.

    As to trying to save the bud blast, they are gone and you can wait till they fall off in your hand or you could cut them. Whatever caused the problem has already been done and there is no stopping it. I have had bud blast so you are not alone!

    Aloha from the Island of Kauai, Hawaii!

    Yes, please stop watering with an ice cube and DO check the root system to make sure they're still OK.

    When you water with Ice Cube, you're putting the plant into a shock. Best way to water if you can is to put water into a bucket (from the tap) and let stand for 24 hours in the same area are where you have your orchid. This leaches out chemicals such as Chlorine and it will also make the water temp close to room temp.

    Think about putting newly purchased fish into an existing aquarium. Normally, you would place the fish bag into the aquarium and let stand for 20 mins or so. This is to get the fish acclimated to the temperature of the new environment and avoid fish shock.

    I wouldn't be surprised that the cause of your bud blast is due to the shock treatment that you're giving it whenever you water it with an Ice Cube, but this is just strictly guess work on my part. 78terp and JDT has given you some good advice. Good Luck.

    I had no idea using an ice cube is bad for the orchid. That's quite an error on my part!

    I would love to take the plant out and look at the roots, but it's actually not in a clear pot. When I first bought the orchid, it was already in a pot with an additional plant with it. I have attached a photo for better understanding of what I mean. I'm not sure how to take the plant out without upsetting the mixture already in the pot, or possibly breaking the roots in the process.

    Hello and welcome. I concur with everyone else as well. It is difficult not to want to do what the seller tells us to do when they try to make it convincing. My first orchid purchase came with instructions to flood with water for 5 minutes once a week. I dutifully did that and killed all of the roots. I was able to save the orchid with this board's help. No mention was made by the seller of checking the roots to see if the plant needed water or that the media should be dry or nearly dry before watering again.

    There are several reasons for buds to fail.

    A failing root system is one, as had been mentioned. The plant is under stress, so flowering will put too great a demand on it.

    In otherwise healthy plants, a sudden change in temperature or drop in humidity, or a blast of drying air can also cause bud loss, and then there's mites. Check the under-sides of the leaves. If you see any fine webbing, that could be the issue.

    LOL Taci! That's why I advocate joining a club and a forum, because mistakes like these can be avoided. Where things can be discussed and be re-butted and come up with a logical solution. One person's opinion may not always be correct or they may be a better way. It's always good to hear/read may views especially from experienced people.

    A case in point: There's a well know gardening magazine that's been around for years, and when I first built a koi pond, I wanted plants in the pond to make it look prettier. The pond was just built and I went out and purchased some 200 baby koi and they were doing magnificently in the pond.

    All was well UNTIL ... I followed instructions in the magazine where they suggested putting a MANURE mixture with the soil which would make the water lilies bloom like crazy. ... and they were talking about FISH PONDS.

    HUGE MISTAKE! Within 4 hours it killed off more than 90% of the tategois (which is similar to kekies in the koi world). And the rest died even after I corrected the situation. BIG LESSON LEARNED. The problem? Pollution and Lack of Oxygen from the Manure!

    Are you guys able to see the photo I uploaded? For some reason, I don't see it was added to my previous post....

    I checked out the roots and it's mushy and brown at the bottom. Definitely appears to be the roots are rotting and need to be trimmed off. What advice can you all give me about repotting the plant? Some places on the internet say not to report a phalaenopsis when it's still blooming as it might disrupt the bloom cycle. What actually counts as a state of blooming? When the buds are still not open or are opening? I also need instructions on how to care for the plant after repotting, and if I need to water it, how often should that be?
