How do i trim such plants?

[johnnytanki]

Hi,

My new tank had started for around 1mths and seems like some of the plants had grown wild.

I need some advises from the guru here on how can i trim the grass which i am having in the pic. Hope to hear from all soon. Thanks

What plants are those?

looks a like blyxa japonica. If so you can't trim it, once you cut the tip the whole leave will rot

b. japoncia used as foregrass, your water parameters must be very good.

You can "peel" off the older leaves or just yank out the whole plant and leave the new young growth aside. It spreads itself out via runners and that is how you control it's growth.

It is an invasive weed. If you do EI and have good light, CO2 and regular tank maintenance, you would have trouble keeping it in check and over running the tank.

i am also not sure what is the plant name..

water parameters good or not..i also not sure..kekke..cos i didnt really test.

i did use co2, on the light for ard 8hours per days, change 10% water per week, thats all.

but i did not see it grow as normal runner leh..basically it start to grow taller and taller..

If i am not wrong, based on my experiece Blyxa will never spread runners. instead it will grow up, up, up, up.....

[johnnytanki]

but normally this type of grass is used as foregrass....if that is the case, will it be hard to maintain?

It a stem plant so no runner and grow up-up-up, but if you cut the top it will grow branch on the side.

[johnnytanki]

Will the leaves rot if i cut it...

also its seems to me it will be unsightly..cos the leave is pointed and after i cut it.

[ExpelledBAN]

If you cut it, it will rot and I heard from places that the whole plant will die.

To trim it you will have to wait til it grows out. It has the same structure as Downoi and Dwarf Lobelia Cardinalis. They will send side shoots near the roots. When your Blyxa gets too big, Take it out of your tank and seperate them.

Like this http://dodoaq.ic.cz/foto/rastliny/blyxa_japonica_6.jpg

You see how a sideshoot came out near the roots.

The principle is the same, trim down. plants will send runners to the side. Thats how we mostly encourage plant mass.
