- Vegetable and Flower Gardens
Vegetables prosper when the surrounding soil is kept quite moist, but
frequent overhead watering tends to encourage rust, mildew, blossom
damage and disease. Closely spaced drip emitters, drip tape, or porous
pipe can balance these requirements by thoroughly watering an area of
soil without wetting the leaves.
A 1/2 GPH emitter will generally suffice for an area 16 inches in diameter.
In coarser soils, 1 GPH emitters should be used for more lateral coverage.
If plants are more widely spaced and deeply rooted, such as tomatoes,
squash, etc., a single emitter can be placed at the base of each plant.
For row crops, such as carrots, radishes, etc., a drip tape, driperline™,
Laser Soaker Line™, or Porous Pipe™ will give a continuous
wetted pattern down the rows.
Drip tape and driperline can be run straight down rows for lengths
up to 100 feet. However, laser soaker line can only be run in lengths
up to 15 feet, but can be wound around plants or around corners. Row
crops similar to those listed above can be planted two or more deep
on each side of the lateral line. With plants such as corn, strawberries,
and peppers, one row on each side of the lateral line is preferred.
If intensive bed gardening is employed, the drip system should be set-up
on a grid with laterals 18 inches apart and emitters placed every 12
inches on the lateral lines. If the bed is 4 feet wide, three laterals
will give complete coverage. A system set-up like this one does not
need to be changed when planting changes. However, driperline, laser
soaker line, and porous pipe will give a continuous band of surface
moisture, while an emitter system allows you to add emitter or sprays
at desired intervals. It should be remembered that, if you are planting
seeds in your garden, emitters alone will not adequately germinate the
seeds unless supplemented with over-head watering with either micro-sprays
or micro-sprinklers. Once seedlings are established, overhead watering
will not be necessary.
