Sisu, Breacher was spot on when he referred to the organic spray comment. When it comes to sprays, you got to go with the real deal. However, you can use Ivory soap and water. Make it real sudzy and spray it on your plants for bugs. When it rains, just repeat the process. Labor intensive.

You can cut sprigs off of lets say a pear tree and stick it in the ground. It will start you a new pear tree. Hope this helps a little bit.

Cant help on the power. Just on things involving Horticulture, Arborculture,agronomy and some agriculture.

Wish you the best.
