White growths on Pothos roots
I am rooting some Pothos cuttings in water. I want to plant them in soil when I've figured out the answer to this question (although I'm aware that you might try to talk me out of it! [wink]), but meanwhile, they're loving the water. This is the first time I have ever put plants (other than cut flowers) in water like this, so perhaps this is a dumb question from the vantage point of people on this forum.
Just when I thought I was ready to transfer them to soil, I took a close look at them and discovered little white bumps on some of the roots. I'm wondering if it's some kind of mold or fungus, or just a normal part of what the roots will do. I've included photos from the day I first noticed them - at the time, four cuttings were in one container - a former instant coffee jar - and two of those cuttings had the bumps. (One more cutting is in a plastic soda bottle, and it has no such bumps.) To the right is a photo of the whole jar and then one of the underwater area - in the middle of the second photo you can see one cluster of the bumps, and there is another cluster that is not so visible in the photo, top right at the beginning of the roots. Below is a super-closeup of the bumps themselves. After these photos were taken, I removed the cuttings from the jar, scraped off what I could of the stuff, washed out the jar, and separated the cuttings (three of the four went in other containers), but the two cuttings that had bumps before have developed a couple new ones again (it has been about 2-3 days). Any idea what this stuff is? Should I ignore it and plant the cuttings, try some sort of eradication, or throw the cuttings away?
