My wife and I are planning to mix our own container potting soil this year, aiming for a pH of 6–7. I’d love recommendations on how to achieve this. From my research, I know peat moss has a low pH (3–5), while coco coir is pH-neutral but needs to be buffered to help plants absorb calcium properly. I’m not fully committed to either peat or coco but prefer a soil mix that allows me to water every couple of days (rather than daily). For context, I’m growing peppers, which don’t tolerate soggy roots. I came across the following recipe online, though it didn’t provide any pH information. I’ve noticed many commercial soil blends include lime but haven’t found many DIY recipes that specify it as an ingredient. Here’s the recipe I’m considering: 6 gallons of sphagnum peat moss or coco coir 4.5 gallons of perlite 4.5 gallons of worm compost My plan is to supplement this mix with 2 tablespoons per gallon of Dr. Earth 4-4-4 dry nutrients for fertility. I don’t anticipate needing more than 20 gallons a year. Unfortunately, I haven’t been able to find Pro-Mix HP anywhere near Newport, Oregon, so I want to create something comparable. It feels like this shouldn’t be too complicated and could be more cost-effective in the long run. Any advice on adjusting this mix to optimize pH and support healthy pepper growth would be greatly appreciated!
