I was just reading a recent article supported by SoilFoodWeb.com and the Earth Tea Brewer folks, that said that if your tea is good, sweet smelling, very aerobic, full of beneficial fungi, you can NOT
foliar spray your plants too much!
Now I foliar/soil drench my plants all the time using an unstrain aerated tea brew using a narrow bottle and a 5 gallon bucket to transport it all over the garden beds. I use this method as a substitute for watering most of my plants. I feed and water at the same time. I haven't used the water hose on my garden beds in about 2-3 months now! Pretty incredible huh?
I've been feeding my sweet corn tea about 2-3 times a week. I just picked my first dozen ears of corn today. It is beautiful! Even with the crazy weather, and increased Japanese beetle infestations here, I still got perfect filled ears!
I read also on http://www.intlctc.org/
that you also mix natural pesticides with your teas, if needed. I sprayed a diluted chewing tobacco tea on mycorn to kill JB's for about 2 weeks in June. After each spraying, I covered my plants withn extra aerated fertilizing/biostimulant compost tea brews. I see lots of extra bees on my flowers now, but no JB's! It worked, and I had minimal effects on my beneficials and microbial populations.
