Hi, I'm new here and need some help! I have two plants that I am looking to repot. One is my venus flytrap. I've had it thriving for a year, and it recently came out of dormancy and it looks like it needs a bigger pot. I also recently purchased a Miracle Fruit plant (Synsepalum dulcificum that got shipped to me. I figure once it gets over its travel stress I would put it in a more permanent pot too. I've read that VFTs need acidic soil, and the care sheet for the MFP says soil needs to be 4.5-6.0, and that alkaline soil will kill it very quickly. Is there a standard potting soil I can buy that is acidic? Or do I have to mix some myself? What would I need? How do I know it is acidic enough? I also water all my plants with dechlorinated old fish tank water, for some nutrients and such. I know from testing my tank for my fish that the tap pH and the tank pH is 7.9. Will the alkaline water affect the soil too? Should I start buying distilled water for my plants, or at least my more sensitive plants? I paid a bit of money for my MFP and I really want it to thrive! Thanks in advance for any help! Edit to add Because of where I live, these plants are strictly indoor plants. Too dry for these humid-loving plants, not to mention the bloody cold winters!
Isn't there peat or muskeg in Alberta? That certainly should be acidic and rainwater you can collect should be fine for the plants.
