Soil ratio too rocky?
I have been lurking the forums for a while and decided to get started, trying my hand with an old epiphyllum plant. After some research, I found that the ratio for the soil should be about 2 parts grit, 2 parts sand, and 1 part compost/potting mix. I've just mixed it together, but it appears to be very rocky, is this normal?
As I understand it, succulents need different kinds of soil but it looks like it's almost too rocky to live in. I've attached a photo from my iPod for your consideration. I couldn't find the answer to this in the FAQ so any help would be appreciated. Thank you!
