Why Are Filifera Seedlings Dying?

loppyshingers(7a)August 13, 2013

I'm trying to grow some W. Filiferas from seed, but I'm doing something wrong; can you help me?

I'm in Lubbock, TX (Zone 7a), and it's been HOT lately (+105f). I originally had trouble with seedlings being knocked over by the wind, so I built this little greenhouse. They have steadily been dying, and I think it's water-related.

They are planted in a (roughly) 80/20 coir/sand mix, but I'm experimenting with a few; they're in a 80/20 sand/coir mix.

I'm thoroughly watering them about twice per week. They seem to flop over, and never come back. The last pic shows the bottom of a dead seedling; you can see how the trunk is hollow and flat.

What do y'all think? Too much or too little water?

Here's what my little operation looks like.

This seedling was lying down in the morning.

Here you can seed that the base of the trunk is hollow and flat. Is this the result of under-watering?

How humid is your climate? CA fan palms arn't too happy in humid climates. They often die. The temps are fine though. It might be that your watering too much or the soil still holds too much moisture. Does the soil dry out before you water again?

West Texas has very low humidity. I usually wait until the top inch or two is dry before I water. After reading about Filiferas growing in creeks, I'm thinking that my problem is under-watering.
