I agree with Adam, most plants like, thrive, and adore foliar feeding. Also foliar ferts are much more economical! I've heard that 90% of a foliar fert is absorbed directly by the plant, whereas only 10% of soil fert is absorbed by a plant, so 90% of your money flushes down the bottom.
It's just very challenging, to say the least, foliar spraying plants here where it rains so much! So mostly i tend to apply soil ferts.
