How to plant Egeria densa?

[wks]

Hi guys, I'm having some problem planting Egeria densa into the substrate. At first I just used the tweezers to push the end of the plant into the gravel. It started rotting with the leaves. In my second attempt, I cut way the rotten portion, removed the leaves from the stem to be buried and replanted with tweezers. The same thing happens.
Have I done the correct way or am I missing something here?
For your information, I'm using lapis gravels.

Hi,
it might be useful to share your substrate thickness, info on base ferts, lighting hours and wattage before we can conclude what could be done.

Cheers!

share tank paremeter would be the best, though I'm guessing it is due to not enough ligh reaching the bottom. Egeria densa is a weed

Jason:

Are they new to your tank? Maybe have not got used to the tank condition yet. How about floating some around the tank? Later you can plant those that have developed some roots.

They prefer cooler water and if you use CO2, hit it with CO2 mist to see if it helps. You should do dosing of macro and micros since your substrate is inert. (Light-> CO2->NO3-> K->Ca/Mg->PO4->Micros).

Thanks for your reply guys. I use a chiller to maintain the water temperature at 27C. I'm using only 2x54w T5 HO fluorescent tubes. Tank size is 4ft x 1.5ft x 2ft deep. Substrate depth varies from 8 cm to 5 cm. Right now I'm doing what Koah Fong has suggested, wait for the roots to grow and try planting again. At the moment I 'm dosing with Wonder-Gro Macro+ and Micro+ and using Dennerle base fertilizer.

Jason: The lights seem insufficient. Your tank is about 90g and lights 108W means about 1.2W/g. The floating Egeria may develop roots but likely fail to grow well when planted later.

I second the light issue, not to mention 2ft deep

I'm worried that increase in lighting level will trigger more algae because I'm still fighting bba, bga, diatom and green spots. Right now they are being checked as evidenced by the slowdown in area of spreading.
