Anderson flats
« on: November 16, 2010, 03:20 PM »
What's the deal?  I see lots of people recommending them, lots more are using them and heralding their usefulness.  Are they better than a similarly-sized-but-without-drainage cement mixing tub?

Just wondering.

They are  convenient, pretty inexpensive, good depth, good drainage.  Nothing magical about them, but it's often easier then building a box from wood.

They are stiffer (thus you are less likely to damage new roots on trees in them if you must move after they get started) and they have phenomenal drainage. I have (and do) use both. JOhn

The root growth you get from using these is incredible.  In just a year, chinese elms and tridents exploded with new root growth.  Granted that these are species that usually put on fast root growth, but they seemed especially vigorous after spending time in the anderson flat.

You'll also see yamadori collectors put newly collected stock in these flats.  For smaller stock, they will saw the flat in half and then nail in a wooden board on the open side to make a smaller container.
