i found one of them at home depot i spent 22.95 for a 5 ft and cut it in to 4 pieces and dipped in extra strength rooting hormone (they make different strengths) set on heat mat at 90deg under 14 hrs grow light 4 weeks have roots. they require warm temps 24/7 now I did this in to 4 " pots and small pieces but rooted before my plumeria!!
now start looking for them they are all over here and several nursery do it that way in the green houses the tree grower i got those for you showed me that and he is producing 100 at a time now!!!
they can not with stand the infrared heat from my garage so i will be issuing you a refund for those dead plants and sorry it didn't work out but we gave it a try the key to it was to not allow them to get that type of heat with out air flow i know that now but if they are easier then plumeria for me i might just have a new end ever!!
refund to come by the weekend paypal needs to clear bank transfer.
