Anacharis melt
Do anacharis stems have a life expectancy? Once a week I trim the bottom
stems and replant. They grow about 8" a week. Suddenly, half the stems have stopped growing, the leaves have turned brown and have curled down. The other half are still growing rampant, seemingly oblivious to the surrounding death. What could have killed half the anacharis? I have a hunch that the stems die after growing to a certain length, and that the half still alive are the younger side shoots. I may be wrong of course. They are growing in close proximity to a watersprite. Maybe the watersprite leeches a growth inhibitor from its roots. Hmmmm. NO3 16ppm PO4 0.6ppm Fe 0.25ppm pH 7.25 K dosed at 5ppm weekly. Nikki |

I've had similar problems recently, but haven't had a chance to research it.

How long are your Anacharis before cutting? I have Anacharis that are
over 24" long in my tank, and they show no signs of wilting on the lower portions. I have two plants that are about 30" and their bottoms are as healthy as the rest of the plant, except of course for the tip which is the lushest, greenest part One thing I HAVE noticed with regards to cuttings, is that I only cut my Anacharis (if I need to that is) once it has formed those long drop roots. On my plants they often 'drop' from about the 6" mark down to the sand substrate. I then snip below the root point, so that the new shoot already has a root. That said, you mention that the older, lower portion dies off. No explanation that I can offer. On a not-quite-related-note, I have Anacharis from my first purchase from the LFS, that are *still* 2" long, yet they were bought in January, whereas the 24" + club were bought in early March. Perhaps different variants of Anacharis tolerate different conditions, handling, etc.. ?? Out of interest, I will cut a 24" plant tonight, and watch what happens..

I cut them too often from the bottoms for them to grow roots. That said, you mention that the older, lower portion dies off. No. The whole stem dies completely, from top to bottom. This is what I have: stems that are completely healthy and stems that are completely dead. No half measures. Nikki |

I'm not sure what the problem is - but I can assure you that anacharis
does not die after growing to a certain length. I had it as the only plant in a cichlid tank once and would routinely pull 2 to 3 foot long shoots of anacharis out of the tank and throw them away. However if you are growing it rooted and the top covers the surface the problem may be as simple as the top of the plant cutting off light to the bottom of the plant and causing it to die. I always grew mine floating on top of the water. But that's just a guess - I really have no idea what the problem is, just letting you know what the problem is not ;-) -Daniel |

They are all rooted. The bottoms don't have enough time to die as they are trimmed and binned weekly. When I say half, I don't mean half of the stem. I mean 1 stem out of 2 has died. The whole length of the stem stops in its tracks, dies, turns brown and decomposes in situ. The healthy stems have beautiful growth from bottom to top. No stems have half dead lengths. I always grew mine floating on top of the water. But that's just a guess - I really have no idea what the problem is, just letting you know what the problem is not ;-) Something else then must be the cause. I use lead weights at the bottom of the bunches to hold them down. Can wrapping a lead weight too tightly at the base be detrimental, like cutting off its resources? They've been growing rampant for over a month, whether shaded or not. This has all of a sudden happened. The only chemical change I've made is the addition of Seachem's Excel. Nikki |

See this link: http://www.seachem.com/support/FAQs/...Excel_faq.html Search for 'anacharis'. I was guilty of this before. I still use Flourish Excel, but in far less quantities. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

I was so distraught by the Excel comment, I forgot to mention the lead... YES, lead can be too tight, and result in dead/dying plants. Do you need the lead weight, or is it just to keep them bunched tightly?

Nikki I would take it one further and stop the Excel altogether until your Anacharis' recovery is well underway. Unless of course, you have other plants dependent on it. I fertilize my Anacharis with Iron, 1/3 - 1/4 dosage Excel (really just to gradually get rid of the bottle!, and also with potassium. I also have PlantGRO 16-9-12 sticks under the sand in the denser areas. Good luck!
