Well...to be honest the cherry and wisteria came potted...I've not really repotted. That mix came from Plant City for he repotted both prior to shipping. (Leaving the wisteria alone for a few years...but wish to put the cherry into the pot that was made by Erin Pottery)
My bougainvilleas I've used bougainvillea BGI soil for them. (The only ones I've ever repotted...but reading about how easily they rot...have been thinking they need less organic)
My lilac's are still in nursery pot with soil they came in. So no clue what they should be put into.
My creeper seems to be in a cheap mix of some sort...but, I read they need to be kept in a deep pot for moisture so thinking an organic mix for them might be best.
I've tried to stay out of substrate threads because they make my head spin...I've heard Boon is good by many. Thus...I thought to go that route. But, think the creeper would stay moister in the Wee brand mix that is more organic.
The entire repotting is a new territory for me.
