The trees can be moved anywhere with a forklift or a truck.
A 70 gallon water tank under the tree wicks moisture up to the tree's roots as needed.
Rain water and sunshine are free. Fruit trees are free. Dirt and boxes are free. You do the math.
The big plastic tubs used here are "macro bins" the winemakers next door gave me.
They are about four feet square. Seen here with a fig tree and a fruiting cherry.
The Tree Dolly was used for transplanting and A-Frame for heavy lifting.
Here's the A-Frame transplant method without tree boxes, just into the ground.
Many thanks to Dad, Rachel, James, and others!
Step 1: How Does It Work?
Along two sides of the platform the dirt extends down to the bottom of the water tank
This wet dirt acts as a wick to raise water up into the rest of the dirt, where the tree's roots can get to it. I call any similar arrangement with rags or dirt a "Pot Wick" or "Potwick". It's fun to say.
There's a 2" overflow hole in the side of the tank at about the 70 gallon mark.
That keeps the water level from getting too high and drowning the roots of the tree. A plant's roots need both air and water.
Tool Box for Thought:
"Soil Mechanics" is the name of the science that studies the interaction between particles and moisture. The "Wetting Angle" is the angle of a water droplet where the meniscus contacts a solid material. The lower that angle the greater affinity the water has for the solid. A very hydrophilic material with a very low wetting angle will have no water droplets on it. The water just sheets out.
"Pore Size" is how large a void is in the soil.
Capillary Action occurs where the attractive affinity at the contact line of the Meniscus exceeds the weight of the water below the meniscus. The water is magically lifted against the force of gravity.
Wetting Angle and Pore Size together tell you how high and how fast the water will move through your dirt.
The particle size distribution determines the pore size distribution.
The pore size distribution determines which pores will contain air and which contain water. Like a sponge, the small pores will contain water and the large ones, air.
Since the roots need both air and water, a jumbled up arrangement of pores is great, so both air and water get to all parts of the root system.
Agitation and pressure compacts the dirt and eliminates large pores. That suffocates the roots two ways. By making a denser mass of dirt between the roots and the sky, and by making smaller pores that wick more water.
