With the menacing, extinct volcano, Mount Suribachi looming in the background and raining down murderous fire, U.S. Marines make their way up the black, volcanic sand beaches of Iwo Jima during the initial day of battle on February 19, 1945.
Soil for Succulents in Singapore
Disclaimer: I’m still learning how to grow many different succulents, but so far this works for me, with plants growing outdoors in partial/full sun. Plants grown indoors might benefit from more well-draining soil.
Where to buy:
Commercial cactus mix: Most nurseries (incl. the ones below) sell this
Volcanic sand (black/red), Perlite (white): World Farm
Pumice: Far East@Thompson, Gardens by the Bay gift shop (the one near the info counter, not the ticketing counter)
1) Equal parts commercial cactus mix and volcanic sand
Use for: Water-tolerant plants - Aloes, Haworthias, Graptopetalum, Kalanchoe, most Sedums and Cacti
2) Equal parts commercial cactus mix, volcanic sand, and perlite
Use for: General succulents - Echeverias, Agaves, Orostachys, Andromischus, Crassula, Aeonium, Gasteria
3) Pure pumice (or pure volcanic sand)
Use for: Water-intolerant plants - lithops, pleiospilos
4) and 5)
A good gauge of whether the mix is well-draining enough is to wet it and clench a handful - the mix should fall apart and not stick in a clump.
6) Pumice vs Volcanic Sand
Pumice is lighter-coloured and harder to find in Singapore (if anyone has good sources, let me know?) It seems more smooth. Volcanic sand comes in black and red and is often quite rough and jagged so it might damage plant roots during repotting.
This is just a general guide based on my own limited experience with keeping these lovely plants alive :) Plants get watered whenever it rains, or every week or two when it doesn’t. When in doubt, go with more well-draining soil as the number one killer of succulents is rot from overwatering/waterlogged soil.
Sandygast and Palossand’s shiny forms are black because they are based off of Hawaii’s Black volcanic sand beach!
The beach is black due to dark volcanic rock being weathered over time.
Another option for the shiny could of been
On our return to Reykjavik, we recall an iconic site told to us by the locals. Giving into our curiosity, we pull off of the highway and shift into an off-road mentality, challenging the sticky, volcanic black sand of Sólheimasandur Beach.
Despite the onslaught of artillery and small arms fire from the Japanese positions on the extinct volcano of Mont Suribachi, pictured in the background, the first wave of U.S. Marines land on the black, volcanic sand beaches of Iwo Jima on February 19, 1945. Today marks the 71st anniversary of one of the bloodiest and most famous battles in United States Marine Corps history.
“A U.S. Marine, killed by Japanese sniper fire, still holds his weapon as he lies in the black volcanic sand of Iwo Jima, on February 19, 1945, during the initial invasion on the island. In the background are the battleships of the U.S. fleet that made up the invasion task force.”
