I'm thinking of using Dwarf Korean Lilacs as foundation plants this autumn but am not sure how to space them. I'm curious of spacing between them and the distance from the house.
All the literature says they're spreading plants with a mature height of 4-5' with a similar width. Let that be your guide. So, at least 5' out from the house and the same or greater distance apart if you want each plant to maintain its individuality. Plant closer together if you're wanting them to knit together for a hedge look.
it would also depend on whether you need access to say .. a wooden house for painting.. or other maintenance..
do understand.. that foundation plantings are planted to HIDE the foundation.. not ON THE FOUNDATION ....
i used to like at least a 3 foot space next to my brick houses .. just to be able to move around back there for window cleaning... trim painting.. etc ....
in trees and conifers.. most size estimates are at 10 years ... and frankly .. they keep growing thereafter .. forever .... i am not sure any shrub actually stops getting bigger .... its just a matter of how long it takes to get to the given size.. and where they go after that ...
try google IMAGES for pix of the plants you are interested in .... for what the future might be ...
Thanks all - great suggestions!
I have 5 Miss Kim dwarf Korean lilacs that didn't maintain a dwarf size. The tag said that they would stay at 5 ft max but, if I don't trim them back they would easily be over 6ft. They're also almost as wide as they are tall making them hard to prune. I'm planning on moving these to an area where they can grow as big as they like. Has anyone else had this problem?
