Yes, but near the soil it is not exact that you pull, you just not allow any movement near the roots when you bend at the top (I tied near the soil first). So you bend near the top and there will be no movement near the soil. In my picture, to the right you see a blue shoe lace near the soil (without pulling but the string is very tight) ; to the left you see the bending near the top. In this way there is no stress to the roots. Hope it is clear.
