"Deep watering produces strong, deep root systems that can safely withstand drought. To help build such a root system requires consistent, thorough soaking of the soil, to a depth of 6 to 12 inches.
A steady stream of water from the garden hose, for example, will only wet the surface and mostly will run off. Plants respond best when the water penetrates below the top few inches of soil. Many weeds have shallow roots that thrive on moisture near the surface."
"1 inch of water, (a general rule of thumb), will give deep penetration of the soil to a depth of 6 to 8 inches. One inch of water or rain is equivalent to 623 gallons per 1,000 square feet. Water should be applied no faster than the soil is able to absorb it.
Find the gallons per minute (GPM) flow rate of the sprinkler being used from the package of the manufacturer. Multiply the square footage to be watered by .62 gallons or 1 inch of water per square foot. Example: 1,000 square feet x .62 gallons = 620 gallons. This tells you how many gallons of water you need to apply to the lawn. Divide that number by the GPM of your sprinkler, and you can figure how many minutes to water."
Erin Farrow: I am the WORST at remembering to water my indoor plants and literally have managed to kill every plant in my house until I started using the Water Blossom. Now I know the water is getting right to the roots and I actually have plants surviving!!!
Nancy Williamson: LOVE the Water Blossoms!!
Michel Cochran: I just put in a new bush and was excited to use a beautiful Water Blossom to give it a great chance to do well and establish a strong root system. A really simple way and attractive way to enhance your garden.
Mary Anne Graham: Fantastic idea!
Lindi Shepherd Riffe: Ours is in our front garden. Our kiddos love pouring watering in it!

"Deep soakings encourage roots to utilize moisture deep in the ground, enabling plants to thrive between waterings."
WSU Extension Faculty for the Tri-City Herald, Kennewick, WA, Written May 14, 2015
"Dr. Troy Peters, WSU Extension Irrigation Specialist, indicates that at their best sprinklers are only 70 per cent efficient in delivering water to the soil where plants need use it.
When watering trees, the soil should be moistened to a depth of at least 12-18 inches in the tree’s “root zone” where most of the water absorbing roots are located."
"Root feeders have become popular for watering trees and shrubs and can be useful if used properly. Most of the roots in a tree or shrub’s root system will be in the upper 12-18 inches of soil. The root feeder should be inserted so that water is delivered to that area.
Shallow, frequent watering …will lead to shallow root systems and high water loss through evaporation … actually end up wasting quite a bit of water and still don’t meet the needs of your plants. Up to 50 percent of the water put out from oscillating lawn sprinklers can be lost to evaporation or drift.
An inch of water penetrates about six inches in a clay soil."
Bangor Gardening Examiner article, “Watering your garden: Deep watering builds healthy root systems”, 2012
"Watering your garden deeply to saturate the soil to several inches … encourages deep root formation and provides your plant with the support it needs to thrive. Because soil deep beneath the plants dries slowly, your plants need only send roots downward to gather water and nutrients.
… deep watering once a week is preferable to frequent, light watering because it encourages your plants to develop a healthy root system. These plants are able to standup to the heat and drought, whereas those that have become accustomed to frequent, light watering wilt – or die – quickly when water is withheld for a day or two.
So, do yourself, and your garden, a favor and develop a routine of deep watering once a week."
"Plants need large quantities of water for growth. Water typically makes up 80 – 95% of the mass of growing plant tissues. Plant water availability is influenced by soil moisture.
If the soil dries without addition of water from precipitation or irrigation, permanent wilting may occur, resulting in plant death. It is critical to manage the water status of nursery crops & to irrigate based on soil moisture & plant needs. Plant vigor and overall resistance to stress from insects and/or disease are influenced by water status."
"Whether you’re planting a shrub or tree, you want to encourage roots to grow deeply. Slow, deep watering is the ticket to healthy trees and shrubs.
Most rains we get don’t deliver enough water to saturate a root ball or are “gully washers” that dump rain too quickly to be absorbed.
Watering well gives new shrubs and trees their best start. It builds strong, healthy roots and lays the foundation for a lifetime of good health. "
"Water Your Garden the Smart Way
Make sure you reach the roots. Watering deeply helps moisten the whole root zone. Watering deeply also builds deeper, healthier root systems.
Make every drop count"
Clackamas County Chapter In Cooperation with Oregon State University Extension Service
"Deep watering throughout the root zone encourages deep rooting and sturdy, healthy plants. Flower beds should be watered to a depth of about 12 to 15 inches. Concentrate your watering in the root zone. The deeper water is applied, the less evaporation that takes place.
Overhead watering of trees and shrubs, whether by sprinkler or by hand, may provide an ideal environment for the spread of fungal and bacterial problems such as apple scab, black spot of roses, and various other diseases. "
