A. griffithii help?!

From: newton at cin.net on 1998.04.26 at 02:04:46(2038) Knowledge desired! I have Arisaema Griffithii seeds. Ready to plant. +More What soil, heat, moisture? How long to expect to germinate? Any good pix out there as to the progress of the plants during this process? I will also go the the Ariseama Page. Thanks... Tim McNinch

BTW, who is updating the hardy aroid list: http://www.premier.net/~chapman/hardy.html This web site is interesting to see how much our Arisaema treasures are worth: http://www.heronswood.com/pren1c.html from this site: http://www.heronswood.com/pren1c.html 'nearly all Arisaema are happiest with a modicum of shade and adequate moisture in humus-rich soil'. Also: http://www.suite101.com/articles/article.cfm/2488 which states that Arisaema Griffithii is not hardy. If I were you I would mail your Arisaema Griffithii seeds to one of our Florida aroiders. I have had very good results with Arisaema seeds or any other seeds by planting them directly into the ground from which they will grow. But first I have to dig into the soil with a shovel, then I till with my little 22 pound tiller, then I add compost, compost cow manure or both. Then I till again with my little 22 pound tiller until the soil is very fine and mixed very well. Most seeds germinate in soil that is prepared like this.

From: grsjr at juno.com (George R Stilwell, Jr.) on 1998.04.26 at 22:33:22(2041) Tim, Don't let Judy intimidate you. We have AEG members growing Arisaema griffithii from Zone 9 to Zone 6a. I've had it growing here in Zone 7a for years. Many AEG members have found it worth while to use the Deno Method for seed germination. It really helps you pinpoint problems, keep track of progress during germination, and minimize space requirements. The method is well known and is described in Dr. Deno's books. You may find it advantageous since A. griffithii is not the easiest Arisaema to germinate. +More Culture for Arisaema is discussed in depth in the AEG archives with step-by-step instructions for the best methods.

From: wpz at sprynet.com (William Perez) on 1998.04.26 at 22:38:28(2042) I soaked my griffithii seeds in a cup of water for two days. I meant to soak overnight only but got lazy. Then I sowed them in a mix of potting soil to which I added half as much of perlite and of vermiculite. I pushed the seeds in only about half an inch, maybe a little more but no more than one inch. Then I poured a layer of vermiculite on top to a depth of about 3/4 inch. I put saran wrap over the top to hold in moisture and placed the seed tray on a wooden plank on top of the radiator by the window. This was sometime in March and in about three weeks they germinated nicely. Afterwards, I just treated them like any old seedling. They're still by the window sill but I've turned off the radiator, only turning it on when it's cold and rainy outside because it then gets cold and damp in the kitchen which is where the windowsill is. Oh, I also have a desk lamp with a halogen bulb over the seedlings and I leave it on when it's cloudy outside and every evening until 10 pm. The seed tray has a whole bunch of other arisaemas and they're all very happy looking. I realize I'm not being very professional about it, but it's working nicely. Hope this helps. +More William Perez

From: stacy holtzman <sholtzma at sunflower.bio.indiana.edu> on 1998.04.27 at 20:54:47(2046) All of my Arisaema species have germinated quite nicely as well in seed starter mix, seeds just laid on top (since at the time I didn't know what else to do), and afternoon sunny window for light (also nighttime kitchen light on too). But some species took almost eight weeks to germinate, and grew a little mold, which did not kill them (they seem to be really tough). They also seem to have a "lag time" between actual germination and growing to be small baby plants - some just didn't do much and then all of a sudden I noticed beautiful little leafy babies.
