Tropical plants (sand tall breath flower pond)
We are located in N. Illinois. Our first frost date is mid October.
I grow about 30 Cannas in our annual flower bed. I do not habe them in our
pond. They are six-eight feet tall. I label each with its color. Allow
first frost, which destroys vegetation. Dig tubers. Cut off all but two
inches of stem. Hose off all dirt. Place in trays for a month to dry in our
garage. Place in plastic garbage bags leaving the openings open. Just fold
over to breath. The garage stays very cold, but does not freeze. I
purchased cheap plastic storage containers at Walmart, 3'x2'x18". In April,
place Canna tubers in tubs. Cover with a mix of one half earth , one half
sand a depth of about 8 inches. Water and keep moist, NOT wet. When sunny
and warm, place outside. At night if cold and frosty, bring into garage or
similar room. They should sprout a foot or so. Plant after last frost, for
us mid May.
I think taro tubers could be treated in the same way.
Professionals would probably dust the tubers with something to inhibit
