Symptoms and Control Methods of Iron Deficiency in Flowers and Plants

Symptoms: The plant grows relatively short, and the top leaves turn yellow or white; the young leaves at the top of the plant show more severe yellowing and whitening, and the growing points and young leaves may even become scorched; the upper leaves of the plant are almost entirely white or milky white, while the lower leaves are mostly brown. Control methods: When applying organic fertilizer or green manure, mix it with sulfur powder and plow it into the soil to lower the soil pH; apply a 0.2% ferrous sulfate solution, using it 2-3 times consecutively with an interval of 7 days between each application.
