What are the symptoms of sulfur deficiency in flowers? How do you prevent and treat it?
With sulfur deficiency, the young leaves start to yellow from the veins and eventually the whole leaf turns yellow, and the root system develops abnormally. With iron deficiency, yellowing spreads from the young leaves to the old leaves. To prevent and treat sulfur and iron deficiency, spray with a 0.30% ferrous sulfate aqueous solution, 3 times in a row, with an interval of 1 week between each spray, and the mist droplets must be fine and even when spraying. At the same time, a 0.20% urea-iron aqueous solution can be used for foliar topdressing.
