    Default Onc. Meredith Katherine buds blasting

    My Onc. Meredith Katherine has produced nice looking flower stalks each of the last two years. Each time all the flower buds blasted. Prior to the last event, I increased watering according to the growers' suggestion. Any suggestions about what could be the cause? The only thing I can think of would be too much heat as the temperature can get into the 90's in the greenhouse when the buds are forming.

    I bet it is the heat. Even once the flowers do bloom some/maybe even many won't last as long as when its cooler. You might want to consider taking them in the house to bright indirect light. I hope this Oncidium blooms for you sooner than later. AL

    I'm assuming that your plant of Onc. Meredith Katherine has started to bloom normally. However, if not...
    You may want to consider boosting your watering while it's in bud. For such a fleshy plant, these really like the water, especially when they're in bud.
    As a side note, it's one of my hybrids from many years ago - named for my daughter. Great to see that it's still around!

    When the flower stalk was well under way a month or so ago, I brought the plant into an air-conditioned room since I assumed the high temp in the greenhouse was the issue. I also tried to water it every three days at least. The flower stalk continued to grow nicely and, as the buds began to swell, I thought I was going to have some success. Within the last week, all the fat flower buds have dropped off. That makes three years in a row that flowering has failed. Next year I'll increase watering and hope for the best.

    I'm not a quitter. I once had a Calanthe for 10 years or more before I got it to bloom.

    The Trichocentrum group is very tolerant of heat - I wouldn't worry about high temperatures. I would keep it a little wetter. Check the potting medium, too. It should be kept in the smallest pot that will comfortably hold all of the living roots. Best of luck!
