Rainmaking with Trees
Rainmaking with Trees is a simple protocol.
Here are the ground rules.
#1. Water slowly and gently. Do not force-water.
Water delivery, per tree:
- 80-95% Rootball trickles
- 1-20% Trunk wetting
- 0-5% Canopy wetting
So, for instance, in this range one 18″ diameter tree might get 100 gallons of trickled-water at its trunk, 20 gallons of water poured down its trunk (gently), and 5 gallons of canopy wetting, for a total of 125 gallons. Or, in this case: 80% trickle, 16% trunk wetting, 4% canopy wetting.
#2. This is a process.
- Take several days to rehydrate a whole grove. Give the system a chance to breathe and recuperate, literally.
- Pay attention to sensible changes in: temperature, breezes, light quality, vegetation, soil and litter color as you go.
#3. Work with the biggest trees you can find.
- Prioritize superlative trees, first, meaning: biggest canopies and trunks. Old growth trees are most effective. If there’s a “mother tree” on your landscape, start with her then move to the smaller trees in the area.
#4. What works.
- Watering 10 to 12 superlative trees in a continuous grove, connected to a large, natural forest system. Watering “how to” details coming soon.
#5. Urban application.
- So far, it appears rehydrating clandestine, urban and campus forests is not reliably catalytic for rainfall generation. It will most likely bring fairer, softer weather and increase an urban area’s overall quality of life significantly. It will certainly help trees recover-strongly from drought, protecting property, scenic and recreational value. These techniques applied “in the city” will also green up your general landscape in lovely ways. It may also result in voluminous air circulation. Our urban pilots have helped make those area more attractive to rain systems when they are present, as well, meaning they get more rain than the rest of the area.
Rainmaking with Trees is the quickest, most-efficient, most-beneficial way to address local drought.
Why RMT
We are in a global drought crisis. Droughts kill. Before the last 100 years of development and global population growth, most of the trees of Earth stood until they fell naturally, some for over 1,000 years. That system, particularly the forests, built itself because of forest moisture-sharing competencies. The same system today is radically destroyed, fragmented, disconnected, young, and stressed. We need to move quickly to rehydrate our biggest, oldest, and most mature trees so they can revive and help the rest of the landscape rehydrate. According to the science, that’s what the big trees do: collect, circulate, and catalyze rainfall; they just need one critical resource to carry this out over large landscapes (hydration).
Outcomes
We can’t guarantee your personal rainmaking with trees project will be a success, especially at first. There are nuances. Timing is everything. Execution, too. But we can give you as much information on how to do it as possible and hope that in trying it out you’ll see results and find your way into becoming a rainmaker with trees.
