We've noticed that many of our stem plants will start sprouting roots from nodes. The plants look otherwise very healthy, so we haven't given it a thought, but it got me wondering whether this was a sign the plants are not getting some nutrient or another.
So I was wondering whether it was normal for stem plants to throw roots off of nodes, and whether all stem plants do this, or only certain species, and whether it is indicative of low CO2/light/nutrients/something else?
I could be wrong, but I don't think it is a sign of any kind of deficiency. Some plants do seem to be more prone to that than others though. Ludwigia repens does it a lot for me. Sometimes when it really annoys me, I just trim the roots off.
It's a happy thing, and many plants can often use it as a means of spreading (allowing them to spread around the area the plant is doing well in). The amount of rooting can vary from species/variety, and on conditions, and can be annoying, but is not a sign of something wrong.
