How long does it take an earthworm to drown? Google wasn't very helpful.
There is an easy way to find out and then you could report back to us.
They drown? Well gee golly. *snicker* Why do you want to drown em anyway, ya big meanie?
Around here they come crawling out of the ground when it becomes to saturated with water. It doesn't take long after that for a car to run them over.
Try this site, go all the way to the bottom.
Why do you ask, Jon?
I have found that it's less than four hours, though I can't be sure how much less.
MJ - Because I have some plants I'm repotting, and I'm finding worms in some pots. I wanted to submerge the plants long enough to ensure drowning for any worms I can't find or tease out.
ewww. You have nightcrawlers in your orchids?? ewwww.
You could be sure if you tried soaking a pot for 3 hours, one for 2 hours, etc. Then you could post here and the next time someone was searching for this information, they would have a good source.oke:
What are they potted it? Just repotting after washing the roots off well would seem like enough to fix the problem. Unless you have them all sitting on rotting benches where they can just cruise on over to the next pot.
Yes, MJ. I do.
Marni - They are potted in decomposing bark or sphag or...? There are some that are packed very tightly around the center of the plant, and I don't want to rip the plant apart to get at whatever is on the inside. One plant I tossed into the pot of water produced a baby worm about 1" long and less than half a millimeter think. It was more or less translucent, and I didn't see it when I picked apart the old media. So while rinsing gets rid of a lot of the prblem, it is proving to be less than a solution.
I like the way Jon mixes Metric with American measurements. Jon it's not like you to let media rot. Must be the job you finally have like the rest of us.
Based on your first post to this thread, I presumed you had turned the corner to contributive posts, Clark. My use of multiple systems of measurement assumed that the caliber of member on OI was high enough that I wouldn't need to stick to a unique school of measuring. Additionally, the job is no more; my media is rotting due to neglect.
I also thought you grew your orchids on benches or mounted. Do you grow some on the ground or do you have climbing earthworms in Denver.
The translucent tiny worms are fungus gnat larvae.
All worms regardless of size, age, and species, take exactly six hours and sixty-six minutes to drown. Except the aquatic ones. They take much longer.
I think you need to burn them out. A little gasoline should help too.....
Clark, Clark, Clark... these grow in my basement. Someone (I suspect a vendor from FL who went out of business a couple of years ago) sold me plants with worms in some pots. They have been in my basement collection since.
This was pinkish, Floozo. It was much longer than a fungus gnat larvae.
I was thinking rock salt, Eddie. They can have a little rock-fight or something.
I once had a problem not too different. Mostly sowbugs and centi/milli-pedes, with some earthworms thrown in. I finally drenched everything with a micro-encapsulated product (KnoxOut I think, but now off the market), repotted everything and made sure there was air movement under the pots and not old wood. Recently a friend with the centi/milli-pedes was recommended to use Tempo by a knowledgeable friend. It may well work on earthworms. A chat with someone knowledgeable at a good garden center or pesticide store might be helpful.
Years ago I had something that I was using in the greenhouse for snails that I tried outside. I think it was a metaldehyde-sevin combination (metaldehyde along doesn't do it). I went out the next morning and there was a bunch of dying earthworms. writhing around on the surface.
That's it blame it on Florida, everybody does.
They call it "East Texas" for a reason, Clark.
Thanks Marni. Another friend suggested Sevin also. I'll see if I can get some sprayed down there.
repot. They wont stay in medium that is not decomposing.
Who the f*ck calls it that?
