Variegation will change depending on light exposure
Will get leggy if not getting enough light!
Humidity
Evolved to grow in arid habitats. Does not require much air moisture. Good for drier areas.
Watering
More succulent, maybe every 2-3 weeks during growing season (spring-summer)
Check if soil is completely dry and water thoroughly when you do.
Test mature leaves (closer to base of plant) to see if they are still firm. Lightly squeeze. If squishy/soft, it needs water.
Prone to root rot
Propagate
Nodes/tubers, can place on top of soil and top off with a light layer of soil.
Can water propagate cuttings (create node by cutting the hearts off). Submerge in water and place in bright indirect light. After a week or two, you should have an inch of roots.
When you cut to propagate, in some cases it can create a split (promote growth)
Pet
Non-toxic
Potting Medium
Well draining, succulent mix, or 50% potting + 45% cacti mix + 5% perlite/orchid bark
Like to be more root-bound and snug
Fertizilier
Once a month in growing season with diluted solution
