Progress pic. @alexandraggg for the soil mixture I have 50% cactus/citrus mix, 25% orchid mix and 25% perlite. I threw in the orchid mix to aerate the soil a bit more and it’s been working out great. They also like acidic soil. My mom throws in used tea bags and used coffee grounds to acidify the soil for her tree when needed. Used coffee grounds also work great when growing blueberries. A ph reader would help out great to test the acidity. They go for about $10-14.
