Propagating Moneywort

[slimeneo]

So I've been trimming my moneywort and replanting the cuttings, but I find that the original plant will fail to continue to grow and eventually start rotting. I tried cutting part of the stem too (the part without leaves) and that rotted too. However the cuttings I cut from the top will root very fast.

I have my lights on ~8 hours a day and I have a DIY co2 yeast system. Am I doing something wrong? Is there somewhere where I'm "supposed" to trim?

That should work fine and the original part should sprout 2 shoots where u trimmed 1 from, are you dosing fertilisers?

 

[slimeneo]

No, I'm not using ferts.

Using CO2 makes the plants photo synthesise faster, this makes them use up the nutrients in your tank faster hence you need to be dosing some ferts.
