Didn't see any current question or new information: Is there a plant nursery in Dumaguete for ornamental plants?
There are a few areas for buying plants. Down east the old Macdonalds toward the ocean they sell plants along one of the streets. At the Robinson Mall outside (highest prices), along the road between Dumaguete/Robinson road and Valencia at the Valencia end there are some groups along the road of mostly small plants but a little of everything. The biggest group is at the Valencia Central Park. If you get to know the growers there you can go to the home growing yards. Good luck
If you specifically know what you want, most likely someone on the forum has what you are looking for. Most plants can be started from cutting or seeds here. Just ask for a small branch.
There a good lady who is very cheap with her plants up toward caseroro falls just before the concrete ends, very helpful and very good prices.
avoid the people at robinsons, prices are astronomical .way over the top get some cutting and some good rooting powder and away you go
What happened to provincial nursery near the hospital? I bought mango seedlings at 30 php 9 years ago.
