My cannas are about 3 ft tall this year already. every thing is looking good so far. leaves look green and healthy.
last year I had either the rollers or grasshoppers destroying my cannas. is there anything I should do to them at this point as far as treating them with anything for pests and or diseases? I have an arsenal of stuff I just don't know what I should use if anything right now.
I am in tx and the average temp right now is like 80 so it not gotten too terribly hot yet.
