Oncidium root dieoff?
I have a large Oncidium in a Coco fiber lined hanging basket with no
potting medium, outside, morning sun, 60% humidity average, 70-90 degrees heat. It is growing roots and putting up 3 new pbulbs. Some of the new roots die back. Any idea as to the reason for this? I spray it to full runoff twice daily with RO water and 1/4 teaspoon MSU fertilizer, morning and noon.. Joe T Houston |

Joe T Houston Do you ever wash the excess salts out? One of the reasons for root tip die back is salt on the fiber. If you fertilize every day the fiber has absorbed the fertilizer and as the water evaporates the salts build up. If there are no pests in the hanging basket I would suggest you rinse the pot at least once a week with plain water to remove the salt build up. SuE http://orchids.legolas.org/gallery/main.php |
