Shrubs - Watering

Consistent and thorough watering gives results…

When water is needed it should be applied in sufficient quantity to moisten the soil to a depth of 10-12 inches for shrubs and trees and 6 - 8 inches for annual flowers.

Watering plants is among the most misunderstood and most often in-correctly handled.

Ideally, all shrubs, trees, vines, bulbs, and annuals and perennials should be planted in soils that have been carefully prepared or amended. This will reduce watering needs by almost one-half because of the better penetration, distribution and retention of moisture.

Preparation generally consists of deep spading, plowing or rototilling. The first few weeks after transplanting are critical with the checking of soil moisture at 2-3 day intervals. Not only should the soil surface be examined but the soil should be checked at the 1-2 inch depth.

Water to sufficient depth…

When water is needed it should be applied in sufficient quantity to moisten the soil to a depth of 10-12 inches for shrubs and trees and 6 - 8 inches for annual flowers. The best approach is to use a garden hose laid in the shrub, flower planting, vegetable row, or near individual trees or shrubs. A slow trickle or drip for several hours is best. Make sure no water is washing or flowing away. The majority of water will penetrate into the root zone where it is most needed.

The average person attempts to water by holding the hose and spraying water onto shrubs, flowers, vegetables. Most individuals, when watering, move to another area as soon as water begins to run and puddle. Consequently, the soil usually is moistened about 2 - 3 inches.

Soil rings are helpful.

An important part of planting is the building of a ring of soil 3 - 4 inches in height and width depending upon the size of the plant. The ring should be as large as the original planting hole or extend slightly beyond the drip line of the plant. The soil ring helps channel water down into the root zone and prevents runoff.

A mulch of 3 inches of pine straw, pine bark, leaves or similar materials will prevent crusting of the soil, fluctuations in soil temperature, and evaporation of moisture. When properly done, watering at weekly intervals should be sufficient, except in hot, dry weather.

Practice thorough watering and the survival and growth of plants will amaze you.
