Stem plants?

When you move stem plants, do they resume growing or does it takes days for them to settle? thanks

Takes a couple weeks for them to re root, and start growing again.

Not really. It will drop roots from all over the stem, and feed quickly from the water. It really doesn't need to be planted.

Sounds good. I just planted some anacharis for nutrient absorption help, seems my new tank is starting to pick up algae. I floated a few stems as well.

Floating Hortworth has no roots to begin/w and only uses ferts from the water column.

Not true, stem plant will grow without any roots and leaf uptake of nutrients is far more important than the root feeding, you can simply test this by letting the stem plant float and watch it grow and shoot side shoots.

I think the original reason for the question was how long before it starts to take nutrients from the water ?
The fact that it's clessified as a different plant from a rooted plant tells you that it gets ferts from the water column much more so than a rooted plant does. In oreder to have growth you MUST HAVE an intake of nutrients. And since stemmed plants are
conditioned for this by nature, they don't need the roots to be mature to start taking the nutrients.
Rooted plants often just exist at the above surface parts till the roots are re-started when re-planted.
My Rotala, both indica and Magenta showed growth on the second day after planting.

they should start to grow within the next day. some sp. do take a while to settle before they start to grow, i think this has to do with nutrients being leached out when you trim them, they take a while to reserve those nutrients back. i could be wrong on this unless someone else confirm this.

I meant adjusting to the shock of being pulled out and moved. If they were never rooted, then yeah, they'll keep growing. But if it was well rooted, then moved, there is a period of shock. Happens to all plants, aquatic or otherwise. I my experience, rooted ludwiga that gets moved won't do much for a couple weeks.

Yeah I think you guys answered my questions, that they're readily take nutrients after being cut and moved. Also, didn't think this through when I planted them, I bunched 3 stems with a lead sinker and burried few leaves. Do I need to replant them or just leave them be? Probably not gonna matter since they're not rooted plants but I would like to do it the proper way.
