Foliar feeding is becoming more popular among gardeners, in part because it seems to be an easy way to fix plant nutrient issues. When your plant is showing low levels of iron, spray some chelated iron onto the leaves and you have solved the problem. The second reason foliar feeding is more popular is that there are more products on the market. These include specialty foliar feed products as well as regular fertilizer which is being recommended as a foliar spray.
There is also great interest in using home brews like compost tea and comfrey tea . Use of compost tea as a soil drench has not really shown any benefits, so maybe it works better as a foilar spray?
It’s time for me to have a close look at foliar feeding and determine if gardeners should be using these products.
