This mix recipe is currently under test...

Rich it looks good.  What's the recipe? :)

What's in there?

Thanks for asking Charlie, but until I get a little more data on it I'll just post pictures and observations.

My goal was for the cost to be about $2 per cubic foot.

Oh it's a secret recipe!  Ok lol it still looks good.  I wish you well with it.

Let's see how it works before we let the cat out of the bag

Not another researcher with secrets. I am still trying to find Black Ischia w/out FMV.

Teasing is not nice, Rich.

:-)

Should work great, as you know these trees are great survivors, some grow upsidedown with roots in rocks, or palm trees.  I would think any soil that contains leaves, bark would be a better place to grow roots than rock.

The mixture looks nice Rich. Perhaps you can share the recipe with us after experimenting with them.

I've used the following mix ; 1 part peat moss , 2 parts garden soil and 1 part perlite. It works great with figs.
I've also used Moisture control potting mix from Home depot. It also works great.

Wood chips/hardwood mulch, peat, perlite, and possibly some sand and compost.

Mystery solved!

Careful with wood chips all, I've done that and they always go under my fingernails when potting/mixing. Hurts like an SOB.

Should also add its a "soil less" mix.

I'd use caution with the wood chips. When that starts to break down the fungal decay process will suck all the available nitrogren out of the mix and render it unavailable to the plants. Bark decays at a much slower rate which is what it is usually used. But good luck all the same.

Yes. I have had discussions about nitrogen drawdown with several people as well read many papers about it.

With the weekly fertilization that we do there would be plenty of nitrogen available for decomposition and for the plant

It takes 1-2 pounds of nitrogen per cubic yard of soft wood bark to compost it.

Mine is no secret...

1 large bag of MG potting mix or Daddy Pete's
1 5g bucket of Cow manure
1 5g bucket of  Mushroom compost
1 5g bucket of perlite
1 5g bucket of top soil
1 bag of soil conditioner (just pine bark fines)
2 cups of pelletized lime

I also mix other bags of potting mix depending what Ihave on hand at the time.  In my opinion, it all turns to dirt over time!

I like that blend, Dennis. I usually toss in some sort of compost material into to my mix as well. Do you ever have weed problems from the mushroom soil? I work down the road from the Giorgio mushroom plants...a lot of locals won't take the mushroom soil due to weed problems.

Thanks for sharing Dennis. Nice mix.

Could you just clarify the second ingredient line, "1 5g bucket of both Cow manure"?

Comparing water holding and retention of Super Mega Mix to MG based mixed I used this summer.

Both weighed 13.2 lbs for the last 2 days

The only weed problems I get is whenever I use dry organic fertilizer. Never, ever again will I use that stuff! The weeds in that stuff grew taller than my figs!

I - 5g of both cow manure and mushroom compost. Too me, mushrrom compost and cow manure is the same. But I do still use them both. My 5 gallon bucket is my guide. A 1 cubic bag of compost is around 5 gallons. hope this helps......

Today I weighed both containers. The results were the same 11.4 lbs
Rich's Mega Mix appears to have settled about 10% less than the MG based mix
