Questions about scree
Hello. I am redoing my semp and sedum area to allow more alpine type plants. A lot of plants I have been looking to get are listed to grow in scree. This is the first time I've ever heard the term scree and I have only been able to find definitions, not specifics. According to what I've read, scree is nothing more then small pieces of rock that build up at the base of a slope.
Does it matter what kind of rock to use and the size? For instance, would I be better off using small pieces of lava rock instead of slate or quartz, or even something smooth live river stones.
Also, should I add anything to the scree, like some soil, or do the plants just root inbetween the loose rocks?
Thanks in advance,
