Purple leaves can be an indication of phosphorus deficiency in plants.
I had a very strange problem develop in my garden this spring. Around the edges of my vegetable garden, I planted marigolds and globe amaranth. Everything looked good, the veggies were growing, the seeds were sprouting, and the sun was shining! But when I went out to check on the garden one morning, the leaves of my marigolds and globe amaranth had turned a dreadful shade of dark purple!
What Causes Purple Leaves?
Purpling of leaves can have a variety of causes, but the most common one is a deficiency in phosphorus. Phosphorus is a nutrient essential for plant growth that is particularly important for rooting, flowering, and fruiting.
