i have tomato plants behind them and worried they are losing out on some sun due to the huge leaves of my sunflower . Is it o.k to cut the leaves back ? or should i just tie them back.
here also is one of my sunflowers that went all odd. i transplanted it from the from to along the fence. must have put it in backwards as it twisted it self around then stopped growing and went black on the top.
Maybe if you spray with Bayer insecticide and water well, it'll come back. Sunflowers are very sturdy. I had one to grow 7-8' tall. They should be gorgeous, but I'm not sure how your tomato will make out being shaded by them. Toms need at least 6-8 hrs of sun a day. Good luck.
