Cool.  I'm going to grow celery in windows facing east and north.

Ooh! Coming along nicely!!

Welp... someone home decided it was just junk and threw my little babies to the trash...

Gonna start a new one, with more things, and a bloody sign "You throw them, I throw you."!

Sad! I hope your new ones are untouched so they have a chance to grow.

Thumbs up!

I'm gonna try to make a time-lapse of its growth, and will post a gif of it. : )

Super nice!  And what a great homage to Earth Day!

Yes, Oce that's beautiful!

Oooo, everything is coming up nicely!

Life finds a way!  Beanie Babies!

Looking more like its parent every day.

Looks like it's ready for dirt to me, Geege!

Nice Geege, time to get dirty I guess!

Geege I like revisiting your celery plant. :)

Me too!  Two years flew by!
