Look for Fafard Nursery Mix, their 51L Mix, or their #3 Mix.

Good aeration and structural stability (of your growing medium) is key. Keeping your trees growing with good vitality is going to take a fair amount of time ..... just how it is - they're like pets in many ways.

I agree with Al.
Was gonna recommend the same mixes.
Many nurseries will order these specialty (but pre-mixed) soils.

Another brand with bark as its largest component is Metro Mix 511. I had pretty good luck with that before switching to Al's mixes. But with any mix that includes peat, you will need to water carefully and repot once a year because it will breakdown and compact. I figure that investing the time and energy to make the best mix for my plants will save me time and energy in the long run.

Metro mix 511... Hmmm I wonder why they call it 511, wonder if their marketing or r n d guys have been browsing these forums at all or if its just coincidence...

LOL! That's my fault. I should have said Metro-Mix 510, made by Sun-Gro.

Thanks. I have a friend who owns a nursery and can probalby get this for me.

I thought I was taking good care of my little trees until I read about the potting mixes. No wonder I lose a couple a year. I love them and have raised some from 12" grafts to 6' trees. and everywhere in between!

I want to fix some of these up between fall and winter.
I appreciate the suggestion!
