Last two weeks a when I was away for business trip, it was raining heavily with strong wind. My sunflower was toppled down and the fall eventually cracked the stem a little. I have to bandage it with soil and cloth, I don't know it will work or not...
Well not long after, there are results...
Check out how tall is it
Decided to move it outside of the house
My personal best, 108 inches, thats 9 feet high
