I have about 20 tridents and Jap. maples in the gritty mix, and they all do very well, with the soil being very forgiving.

I don't have quite as many trees as Al, but my Tridents are also in gritty mixes - younger material in the 5-1-1, and older material in the Gritty Mix.

These mixes can make re-potting a pleasure....

...... for you, maybe - still drudgery for me; although they DO make repotting much easier. :-)

I have mine in the gritty mix..

The best thing I ever did...They are growing wonderfully, and so easy to transplant into a bigger pot because the mix falls away from the roots..

Thank you Al for the idea!

Mike:-)
