The link does not work it asked if I'm the owner of the page and to put in a username and password

Digdirt's (now) dead link was scraped by the wayback machine archive - Below is a snapshot of that linked Acai Palm page in 2011 when it was still working:

I have about 10 plants I planted from seeds. That was about 11/2 years ago. Now they are about 1 ft high. I have had no problems with them. Even in the winter time when temps get in the mid to upper 40s a couple of times they did great.
I live in SW Fl. and we have hot humid summers, so conditions seem to be very good. I do give them some plant food once every 3-4 weeks. I plan on keeping them in pots until they get about 6-7 ft and then put them in the ground.
