    Question Can you trim Vallisneria, like grass?

    0 Not allowed!
    As the subject heading asks. I've read various reports of moderate success with this technique - just trimming the leaves down to the desired height, like grasses. Some have experienced die back using this method.

    I have a few too many starting to grow along the front of my tank and I'm not keen on letting them get too tall. This is the tank it's in. You'll see it's spreading at the centre-front.

    Has anyone had any experiences to share with trimming?

    Tanks look good but that aside..

    You can prune vallis leafs but in my experience the leaf sooner or later dies. If you just want to manage plants a bit I tend to remove the leaf as low as possible.

    Hmm...I might try a test patch of trimmed vals first. My alternative is to pull it all up and move it, and then plant stargrass along the front.

    I've been trimming mine like grass for years. Generally when they about reach the top of the tank I cut them back 6" or so.

    Sometimes a leaf does die, in which case (if the critters don't eat it first) it tends to detach and float away. Overall though the individual leaves seem to last for a long time.
