Well, WYSuzie, I hate to tell ya' but container gardenin' in Northern Tundravania isn't the best of ideas... Ya' see, it isn't when seedlings are put in but the temperature of the soil... Containers just don't hold heat like real dirt, however...

...there is an answer... Poor Hardi needs to build you some raised bed containers out of RR ties... You can build them any height and use reinforcement rod to hold them together by drilling them and pounding the r-rod down to act as pins...

The advantage of these will be that they will hold heat and be at a level that you are comfy with... They are also decorative, easy to mix variuos soil ammendments into and user freindly... And they are cheap... Relativeluy speakin', of course...

There is an organic hippie farm over outside of Mt Jackson that gardens this way and they get super yield out of very little space... If you want, I have their contact info and you can call them and they will be more than happy to walk you thru setting up an attractive, user friendly and high yield raised bed gardens...
