Come April (which really should have been late March), I had several canna bulbs to plant in quart containers. The most important thing is to make sure the right end pf the bulb is pointed up, and that you use good potting soil, not garden soil. Mom came over to help me get them planted, and then I got to put all my little bulbs in the sunny window until they started to spout.
Only two of the 6 Tropicannas spouted, but I got 4 out of 6 of the other variety to leaf out. Memorial Day weekend, we finally planted them in their planters out on the patio. It was so impressive to me that only two months in the pots created almost perfect root balls! Check it:
Unfortunately, we didn't have any potting soil at the house so I used garden soil mixed with lots of peat, sand, and hummus to help with drainage. Straight up garden soil doesn't do well in containers because it's compacts and doesn't allow the water to drain as well as lighter potting material.
I also picked up some sweet little rolling plant stands to make moving them around the patio easier. I may spray them black, and possibly take off the price tag. If I get around to it.
If my mom hadn't told me to store the bulbs over the winter, I would've had to re-buy these for over $20 this year. I feel like I just got free plants, and I can't wait to see if they get just as big as when I purchased them last year. Thanks for your plant wisdom, mom!
