So, what is the plant lover to do without sufficient water? The answer is to use water more intelligently, and to do this by using the Groasis Waterboxx.
|The Groasis Waterboxx|
Most water poured into the soil is not directly used by the plant. It either flows away through the soil or evaporates into the air (especially in hotter climates). There are multiple techniques to prevent these losses (planting in containers, using mulch) but these have serious drawbacks (cost, easy drying out of roots, poor evaporation blocking ability of mulch). The Groasis Waterboxx deals with all of these issues, as explained below.
The Groasis Waterboxx was initially designed to plant and grow trees in the desert, with water only added at planting. In this it has been remarkably successful. In a Saharan Desert planting trial, single trees planted with the Waterboxx had 88% one year survival (vs. 11% survival for trees watered once weekly but without the Waterboxx). The survival rate for at least one tree increased to 99% when two trees were planted in the Waterboxx as intended. When planting a tree with the Waterboxx, 10 gallons is poured into the soil before planting, the bare root tree is planted, and then the Waterboxx is filled with 4 gallons of water. No water ever again needs to be added as the Waterboxx collects dew and rain water and slowly releases it to the growing plant through a wick in the base of the Waterboxx. The Waterboxx is left in place until the tree outgrows it and can be reused for up to ten years. The Waterboxx planted tree is then resistant to drought because of its deep, capillary water fed roots.
What about gardening? Well the Waterboxx can be used to grow many fruits and vegetables as well. Generally, since vegetables require more water than trees, we recommend inserting a second wick into the base of the Waterboxx for water loving garden plants. If this is done, water generally needs to be added to the Waterboxx every 3-4 weeks - again 4 gallons. However, as the Waterboxx prevents evaporation of soil moisture immediately beneath it (by acting as a type of impermeable evaporation barrier, a far better alternative to mulch), the roots of the plant won't dry out. Below you can see results of a customer growing tomatoes with the Waterboxx (with extra wicks inserted) in Hemet, California in late 2014.
