* Make yourself a cup of warm brew and go outside and observe your garden & trees & use all your senses to breath in deep the wonders unfolding.
* Water the trees deeply once a week, provide some extra nourishment through foliar feeding when you're able, prune out & remove dead wood or heavy insect infestation, and research the insects life cycle and take action based on what you learn and intuit.
* Share your experience with others.
If you have just moved into a new home, often the best thing to do at a new homeland, is observation for a whole year – full solar seasonal cycle.
Some of your choices are the “Do Nothing” method of waiting it out with the critters, or the “Manipulative, Armed & Dangerous' methods.....or the method written of in my blog of “Co-creating as a Garden Servant providing water & nourishment & diversity”.
