I've read that some leave damaged or dying leaves on the plant until they rot away, while others prune these same leaves. The rationale for leaving them on is apparently that they'll continue to absorb some (albeit less) nutrients and provide energy, while the rationale for pruning is to prevent algae from growing and to eliminate the plant's focus of energy toward damaged/dying leaves in favor of healthy and/or new leaves. Which approach is correct?

This theory is a bit of a new one on me l aways assumed old plant leaves are best removed and the plant will be better for that ,as it energises the plant in new growth, maybe you have read this somewhere as part of a wider context?Maybe one of the plants expert will come in on this

I wouldn't ever leave leaves to rot away, for various reasons, not least because it increases organics, encourages algae, and is aesthetically unpleasant.

Generally speaking I remove damaged and dying leaves as soon as I notice them if I think the plant can withstand the loss; that can depend on how many leaves the plant has, how vigorous it's growth and the species, and the growing environment.

For instance, it's perhaps a good idea to leave some damaged leaves, or those with some algae if the plant is trying to establish itself.
Once established and new growth starts to come through then it maybe a good time to trim old and damaged growth.

Although I never got to the point of pruning as my plants usually don't get to grow that much, this is very useful and thank you for putting together

I'm having a bit of difficulty figuring out how to best plant Lagenandra meeboldii Red Aquafleur.

Any one any tips?

If you want your stem plants to branch out and fill a larger area then snip off the very top section and new growth will be diverted to side shoots further down the main stem. This is useful when propagating Ludwigia etc..

I have my first planted tank so Im confused a bit. I need to leave for example L aromatica to grow as high as I want it to be and then cut off the tips to make her more bushy or I cut of the tips as it grows?

I have hard time in making stem plants bushier and at the same time to make them keep leaves on the bottom too
