i read ten pages before i gave up looking for my question and decided to just post it, sorry if it is a repeat, can anybody tell me what i need to make a citrus ball cactus? the 4 tier guide i found starts with that and i have none and no seeds to make it, so it won't tell me what seeds to look for or can somebody direct me to the guide that has all the plants instead of just the 4 tiers? thank you for your help and patience i know these answers probably are posted somewhere else
