I have a rabbit's foot fern I will be repotting soon, and everything I read says to make a mixture of 2 parts peat moss, 1 part sand, 1 part perlite or 2 parts peat moss, 1 part loam, 1 part sand/perlite.
However, upon doing further research I see a lot of things suggesting that peat moss has a very low pH and that it is necessary to add garden lime to correct this. Unfortunately, nobody is able to describe the required ratios, and to complicate matters further it sounds as though garden lime has a slow effect over time.
Is it really necessary to neutralize the peat moss, or is it fine to use as purchased?
For example, this site says to use 2 parts peat, 1 part soil, 1 part sand/perlite: https://www.gardeningknowhow.com/houseplants/rabbits-foot-fern/repotting-rabbits-foot-fern.htm#:~:text=Use%20a%20potting%20mix%20with,the%20edge%20of%20the%20pot
However, these websites all say that rabbit's foot fern prefer a neutral pH soil:
https://www.wikihow.com/Grow-a-Rabbit-Foot-Fern (neutral pH of 6.5 to 7.5)
https://davesgarden.com/guides/pf/go/54822/%20http://davesgarden.com/guides/pf/go/54822/ (6.6 to 7.5 (neutral))
https://plantcaretoday.com/rabbits-foot-fern.html (neutral pH, but goes on to mention the same recipe)
