| Aileen Yeh delivers 8 healthy Alani seedlings ('04 seeds) to Maui while attending a conference on Koa wilt, a new problem threatening Maui native Koa. |
How I grew the alani... I clipped some seeds, and some I didn't I use the band pots because they tend to give better root growth, with minimal root circling in the pot. Less chance of self girdling later on. One of the
main problems I've seen in koa plants in the landscape is people plant a large tree which has a small, usually round pot. The roots circle around, and after it's planted, and the tree is big, like after 5 or more years, the tree might start showing signs of dieback. When we dig down around the tree, we find the roots have circled around the
trunk, and it chokes itself.
Anyway, I digress. For the alani I took over, I put a bit of sphagnum moss in the botom of the band pot to keep the media from falling out and to keep it moist. I use a mixture of Sunshine mix #4 and large perlite. I started the Alani in forestry tubes, and after they got to be about 4 inches tall, I transplanted them to the band pots which they were in. It is best to keep them elevated so that the roots come down out of the pots and get air pruned, rather than circling around, which is what would happen if left in a solid tray. You could use cinder instead of perlite to lighten the media.
Aloha,

Here is a picture I just took today. They are actually bigger than I thought. Note the Sharpie pen stuck in the black band pot. Hope this makes your day. All the seedlings in that rack are the Alani. Aloha, Aileen

I am attaching a photo of the Alani seedlings that have
survived. I had a total of 20 seeds germinate (20% germination). The seeds
were sown around September 26 and 28, 2004. Of the 20 that germinated,
one damped off, and one got the top cut off. I'm not sure if it was a
slug or a bird.
Twelve of the seedlings look great, and 6 of them are kind of small, and
do not seem as vigorus. The seeds that I soaked for 48 hrs then sanded
had 7/25 germinants. The seeds I soaked only for 48 hrs had 3/25 germinants.
Then again, the batch that I did not sand, but just soaked, had 11/50
germinants. I have checked a part of the remaining seeds, and they seem
to be just dormant still. There is hope that more will germinate. Thus
far, I have drenched them with Gnatrol for fungus gnats, and sprinkled
some slug bait around. Also sprayed them with Merit just in case.
At this time, I'd like to ask what kind of place they grow in, and what kind of media they like, and how much water they prefer. I am at the 500 to 600 foot elelvation, and the greenhouse is fairly cool and shaded. Mahalo, for letting me try my hand on this most precious seed. If anyone has suggestions or comments, they can email me at tayeh@gte.net

I am happy to say that 3 of the alani seeds
have sprouted within the last week. I know there wasn't anything up a
week ago.
Hopefully, there will be more. These were sown Sept. 27, 2004, and were
not sanded. they were soaked for 24 hrs, and sown into Sunshine mix in
dibble tubes, and covered with vermiculite. That is a germination time
of less than 2 months, so I'm suprised. Have a Happy
Thanksgiving.

I received the seeds in
good condition, and will get started on them today. I have in the past
grown 3 other species of alani from seeds. One had very tiny seeds, and
one had seeds about the same size and appearance as these that you sent.
(They were such a challenge, and take a long time.) I have tried using
a Sunshine and cinder mix, as well as perlite:vermiculite, and tried sanding
them, but I don't think sanding helped me at all! I was so glad to see
that there are so many others that are growing alani, and it is great
to see what other's are trying. One thing I have done in the past, was
to sow the seeds into individual containers. I use tree tubes. Then, it's
easier to keep track. I have noticed that after transplanting into larger
pots, they sometimes get a leaf curl. Once in awhile, I find aphids. I
will let you know what happens.
Aloha,

Dear Ms. Moran,
I recently read the article in the Maui news about your work with alani.
I have been growing alani from seed, and had found that nicking and soaking
worked well. I was wondering if you had any extra seeds I could try? I
would appreciate it. If not, I'd understand. If there is anything I could
help you with, I surely would try. I work for Hawaii Agriculture Research
Center, and hav a small nursery where I grow trees for reforestation,
as well as some native species. Of all the natives, the alani are my favorite.
Mahalo.
