10-20% mixed into the soil when you repot. It doesn't need to be exact. As Richard says, river sand is also a good ingredient. I would imagine 10% as well.

I've read in the forum here that about 1/3 the soil can be perlite or vermiculite. I use 1/6 perlite and 1/6 vermiculite (since vermiculite is cheaper here) when I repotted my bananas.

But since the perlite or vermiculite is primarily used for drainage, I'm not sure if it will help your yellowish brown leaf tips - unless of course they are caused by poor drainage.

I like to put more perlite towards the bottom. After awhile, the soil compacts there & may cause root rot. Also, perlite eventually floats up towards the top.

I'm growing out some Ensetes and since they need really good draining media I'm mixing pro-mix and perlite 50/50. I'm with Patty I put some straight perlite in the bottom.

I use 50/50 when potting freshly cut pups.

I use 1/2 perlite for my plumeria cuttings, and 1/3 for nanas. I put the perlite in first, then the sterile potting mix, them mix by hand. The result is more on the bottom for the same reason offered by Patty and Micheal.
