TomO Posted December 11, 2020 Share Posted December 11, 2020 What would cause my some of my stem plants to throw out so many roots from above the substrate? Link to comment Share on other sites More sharing options...
Daniel Posted December 11, 2020 Share Posted December 11, 2020 Those are called adventitious roots. It allow plants to propagate vegetatively from leaves and stems and is completely normal. Many plants propagate almost exclusively from leaves and stems and almost never from seeds. 1 Link to comment Share on other sites More sharing options...
WeehawkenFish Posted December 11, 2020 Share Posted December 11, 2020 That 2nd pic looks like pennywort. I don't even plant mine I just float it on the top and it grows like crazy. Totally normal for it to want to feed from the water column. 1 Link to comment Share on other sites More sharing options...
TomO Posted December 11, 2020 Author Share Posted December 11, 2020 So to propagate them, trim and replant horizontally? Link to comment Share on other sites More sharing options...

The stem plants, like water wisteria? If yes, you can cut them and plant, but you don't need to plant them horizontally. Link to comment Share on other sites More sharing options...
TomO Posted December 11, 2020 Author Share Posted December 11, 2020 The ones in the pictures with the adventitious roots. Or do I trim them on the stem between the roots and plant the vertically? Link to comment Share on other sites More sharing options...

The parent plant will sprout new growth and the cutting will grow into a new plant. 1 Link to comment Share on other sites More sharing options...
