to winter? then why do they grow in your yard in the summer if you dont mow your grass! Maybe the willows rotted because the stem was getting wet and not just the roots? the pothos sometimes I keep some stems wet, but all the other plants I have the roots are in the water and the plants are not. The plants will be fine if plant and 1" of roots are above water. I got more maple seeds today, gonna research the best way to sprout, maybe in dirt first then transplant. Saw a willow tree while driving today, but wasnt within my legal access, dang.
