It's been in the 80s so I don't want any more heat. Lol.
I live in 100% sand. My bananas grow great in my native sand. I would never go buy sand to haul sand to add sand to my sand to grow my bananas in ground in sand.
My rooting sand is a little different than native sand. First of all when I say course sand I am talking about quartz silica. More ground up rock than sand. Sandblasting sand is alwsome too.
I also use clean course sand for 1 purpose only. Rooting corms. They stay in the sand a month max. After they develop roots I plant into soil. I have tried Over 50 different mediums to root in I bet and course sand is by far best at rooting faster and easier. Another major factor to rooting in sand is that you can pull up the corm while flushing water and check roots and progress without damaging any roots.
Fill a pot with native sand then fill a pot with pool filter sand (quartz silica) and see which drains faster. No matter where you live it's the quartz. It's made to run lots of pool water through and you see how fast the water comes out of the pool jets.
The reason it drains better is my native sand has broken down organic material and silt. As all uncleaned sand has.
I don't agree with planting in ground with it if you already have sand. If your in clay maybe. I can't say since I don't have experience with clay.
In a pot I never use sand. Anything I pot will be transplanted into the ground later. If you add sand when you remove from the pot to pot up to a larger size or plant into the ground half of the rootball will fall down onto your feet since the sand is loose and will not hold together outside of the pot. It can really set a plant back.
I always use perlite. I mix peat moss and 30-40% perlite in my potting mixes. Perlite is popped volcanic rock and has tiny holes and cracks that hold water for roots to access. Perlite is also super light making moving pots around easier. If you grow bananas in pots you really need to try perlite. Bananas love it.
Anyway guess im on both sides of the sand wall.
