Nothing wrong there, other than my dislike for the pine. I would use hardwood or cypress, but that's just me. There are literally dozens of workable formulae and hundreds of variations of those formulae that work well. This is not rocket science. LOL

Well Doc, to some it's rocket science...lol....But obviously with your experience, and a DOCTORATE degree in soil and more, lol, it's interesting just to read your views....Muchas Gracias mi amigo.....You're very kind!!

Chuck, thank you for the kind words but I am not a doctor of anything that has to do with horticulture. I wish I knew 100X what I do. That's why I value ATP. There are so many folks out there that are far more knowledgeable than I. My degree is in dentistry, but since I am now fully retired, I don't even use the Dr. any longer. The reason I am sort of knowledgeable about potting/garden/landscape soil is because I have a tiny, cottage business growing and propagating tropical plants. I needed to do something in retirement, so Tropical Plants & More was born.

Hey Doc.....Again, "Gracias!".....What would a the colorful, easy maintenance plant for the inside of my home for wifeypoo?.....Tropical wise etc!!....Thanks!......Average size!.....Chuck.....U DAH MAN, so tell me!!!!!!....Have had some bromelaids, but they're good for one blooming, though the greenery is everywhere!

Ficus makes good houseplants, either Fiddle Leaf, Rubber Tree, or Narrow Leaf (Alii'). None of them boom but have nice color.

For myself if I was planting trees shrubs to pots that I intended to hold in pots for a longish time I might want a drier looser soil like:
1 part soil conditioner (pine bark) sifted
1 part sifted granite grit (also sold as chicken scratch)

I use a one gallon scoop for my 'parts'

Other flavorings like sulfur, oyster-shell, compost, osmocoat pellets get used by the spoonful to cupfull.

What ever will not pass through a 1/2 inch hardware cloth is too large. Discard the gravel, chunks.

What ever will pass through a 1/16 inch window screen is too small, discard that too.

This is pretty much what I use for bonsai soil too.

Well dang. I just found that there was a forum foil soil mixes. It is old and quite inactive.
Maybe you guys could bring it back to life.
