A couple questions. How do I re-pot an orchid? It says to use 3 ice cubes once a week. Has anyone tried that before? There are knats in this plant and I'm not sure how to kill them without killing the plant. Any suggestions would be greatly appreciated.
I have gnats in one of my plants too. Get some rubbing alcohol and put it in a spray bottle and spray the dirt or leaves or wherever you see bugs. You can also use a cotton ball or q-tip or anything else. Keep the plant out of direct sun for a couple days after spraying with alcohol.
@ilovefrog82 I can't help with the knats. Everything I read said not to use cubes but I do and they are doing great. I actually freeze the orchid liquid feed in the ice cube so they get food and water in one.
@ilovefrog82 here's a video of @ashleyglassman using a spray bottle of alcohol to kill bugs on an aloe. This would work on an orchid too. And my orchid lady who repots my orchids gave me the same advice to peel away the old dry bits of leaves to keep bugs from getting in there. https://youtu.be/ZQGK4wcCm-g
You can probably find other YouTube vids about how to repot orchids. The mechanics are easy enough. The most important thing is to use soil that's appropriate for your local climate. (I don't keep bags of orchid potting mix around because I live in an apartment, so I have a local orchid grower do mine for me every couple years.)
You could also unpot your orchid, and then bake the existing soil in the oven at 350 for 20 mins to sterilize the soil and kill any other bug eggs. (But it's way less hassle and mess to use new soil if you have it)
