You can tell the Yankee's in this string - heat packs? In Texas we want the ice packs !
Don't get in an uproar - I am a "many years ago" transplant (TWICE!) from the east coast and that doesn't mean I like it here - just haven't found my way home!
Life has me in Texas so that is where I am!!!
We have bought plants & fish from Live Aquaria and really like the way they pack - so anytime we prune to ship plants we use the wet newspaper wrap in an oversized ziplock baggie - then lay into a box filled for support. try to keep them in transit less then 3 days for best results.
