Spray compost tea however you wish. Without question you will find 100 people who do it that same way and another 100 who will tell you that you are doing it all wrong. There are no rules regarding compost tea other than if it doesn't do as you wish it is your fault. No idea about stinging nettle tea.

I think that hose sprayers are a bad idea for two reasons not even considering the fact that it would be very difficult to pull a hose around my garden. First hose sprayers will cost you a lot more because you use more spray because they are less efficient. I have a Rocket sprayer which holds five gallons and puts out a fine mist that covers the garden completely with 10 gals. of spray. It requires 5 tsp. of BannerMaxx per 10 gals. for a cost of about $3 for the whole garden. Based on my experience using hose sprayers for spraying fruit trees I would guess it would cost at least 3-4 times as much if I were using a hose sprayer because it would require that much more fungicide. This leads to the second and more important reason which is that we should be using as little chemicals as possible because we want to harm the environment as little as possible. Regardless of whether you use Bayer or whatever it is a powerful poison that we shouldn't use any more of than is absolutely necessary.

pka, awhile ago in the threads I talked about a product I was testing, called Messenger that I foliar fed all my citrus and all my other plants inside and out.Which by the way I still do. Could this have been what you were possibly thinking about? I have not read in any of the threads that Miracid was was foliar fed, that I can recall. So now I guess if your insistant on foliar feeding once in awhile,which is also benificial...then your going to have to use something else.Miracid is to be applied to the soil.And before you use this product,you should test your soil for acidity.You surely have gone the extra mile buying & trying,but to NO avil but I applaud you for this.***Suzanne
