Went to visit in-laws in Oro Valley Arizona and fell in love with the
Blue Palo Verde trees. Once we got home I bought some seeds on Esty from a grower.
I sprouted them as recommended using paper towel. Once sprouted I transferred them to good quality fast draining soil and put them under a grow light for a few weeks. I know they are slow growing but these seedling seem to have stalled and are not growing anymore. They have been this size now for two weeks. They are to fragile to plant in ground so not sure what to do now. I can put them outside in the warm shade but they will dry out real quick with the heat here in the planting cups I have them in now. My confusion is at this stage how much water do they need and for how long. Live in coastal community in Galveston, TX. Not same climate as Arizona but I have seen a few here in the ground. Any suggestions? Pictures of current state included.

I grew my Palo Verde from seed but its been quite few years. I didn't start it on a paper towel, just in a pot of soil. Unless you cut a little piece of paper towel out with the roots, you may have damaged the roots a wee bit. It will take some time to replace those roots before the tree grows again. Be patient - as long as the little plants are green, they are growing.

Palo Verde trees grow fast and are beautiful but there are some drawbacks: they're hard to prune because of all the thorns and they drop copious amounts of yellow flowers smothering everything beneath them. They're also pretty brittle and break easily in the wind.
