Can you recommend a source for cactus and succulent garden gravel?
At the NYBG, we buy expanded shale aggregate from Norlite Corporation in Cohoes, NY.
However, I am not sure if they sell the big boulders we use as edging. I believe we have had those for many years. You can ask what sizes they have available. Judging from the size of your garden, it doesn’t sound like you will have space for very large boulders anyway.
For tips on a variety of gardening topics, see our Plant Information Guides.
