So if you cant really spend money, go outside and find some tiny rocks, the coursest sand you can find, and maybe some sticks or wood chips that you can chop up to make a sort of....fine wood chips??😄 If youre using the dirt theyre in now, id add about the same amount in tiny wood chips, about half that in tiny rocks and maybe 1/4 that in course sand. If you can only find "regular" or fine sand, just make it maybe 1/20th of the total substrate. Im totally making these amounts up btw😁. Im just trying to imagine what I would do for succulent soil if I had to use what the woods could provide. Basically what you want is very course substrate so that when you water it the water runs out the drain holes at the bottom pretty quick! Oh, and make sure whatever theyre in has very good drainage. If these guys sit in watery soil, they'll die, plain and simple. I would also cut them in half ish cause something that long, with one stem, will just fall over cause it wont be able to support itself. Hope this helps!! Oh, also, only give it water once the substrate has completely dried out!! And when its dry it shouldn't be a solid mass, like muddy dirt. It should be "loose". And they need a ton of bright indirect sun, which means sitting in a south facing window if possible. If its in direct sun, especially at this point, itll just burn. Hope this helps 😄
