2. Use mulch.
Planting thickly and using mulches helps shade the soil and keep available
moisture from evaporating. Chipped bark, straw, grass clippings, cocoa
hulls and compost are all effective as mulch. However, when using bark
or anything else that does not break down readily, be sure to apply no
more than an inch or it may keep water from percolating down to the soil
where it's needed. Mulches made from organic materials add valuable nutrients
to the soil as they degrade.
3. Plant appropriately.
Consider planting varieties that are drought resistant and appropriate
to your geographic area and climate. In addition, cluster plants that
have similar moisture needs. For example, many herbs, plants with hairy
or gray leaves, and sun-loving perennials such as coreopsis and yarrow
do better in a sunny, fairly dry bed. Keep moisture-loving plants like
roses and classic perennials such as delphiniums and peonies together
in a bed that can be watered more frequently.
4. Minimize
wind. Wind can suck moisture out of soil and plant leaves faster than
the blazing sun. Plant or set up wind breaks that allow the sun in, but
shield plants from strong winds in exposed garden areas.
5. Measure
moisture. Before turning on the sprinkler, determine how much water your
plants really need. Especially if you've been following the advice above,
you might be surprised how much moisture your beds retain, even when it
hasn't rained for a week or more. Dig down into the top 12 inches of soil
and make sure it's dry before you water. If you do water with a sprinkler,
put a bucket out to measure how much water is falling onto the ground.
Water in the morning so plants have the resources they need to face the
noontime sun. Watering in the morning also helps reduce fungus and disease
problems, because the foliage has a chance to dry before nightfall.
The following
tips will also help you conserve water:
1. Water infrequently
but deeply. Roots grow where the moisture is. If you only water the top
couple of inches of soil, that's where the roots will stay. If you water
deeply, they'll extend their reach and be more able to withstand occasional
dry spells in the future. Be sure to water long enough for moisture to
reach at least a foot into the soil.
2. Put the
water where it's needed. Plants take up water with their roots, so this
is where the water should go. Build small dams around the base of your
vegetable plants to act as catch basins, and direct the hose or watering
can onto the ground, not over the top of your plants. Apply water slowly
so it soaks into the soil, rather than rushing away over the top.
3. Choose a
water-wise sprinkler for watering. Sprinklers can waste a lot of water
through evaporation and by scattering moisture to areas that may not need
it. There are a variety of water-wise sprinklers available, but also consider
using soaker hoses for beds and water spikes for individual plants.
4. Weed, wait,
cultivate. Reduce competition for water resources by keeping your garden
well-weeded. Wait until plants show signs of distress, such as limp leaves,
before watering; most plants will quickly recover. Break up compacted
soil so water will absorb into it rather than run off.
Following even
some of these good watering practices can reduce water consumption and
time consumption by as much as 50 percent. This savings is particularly
important when hot weather arrives and many communities begin implementing
water bans.
Here are some
other products from Gardener's Supply that can help keep your garden green
while conserving water. To get water directly to the roots, use Gardener's
Supply's Aqua Cones. They provide an economical method to get moisture
directly where and when it's needed. Recycled plastic soda bottles hold
the water and the flow can be adjusted for any type of soil. They're also
useful for plants such as roses that are prone to mildew or black spot
if the leaves get wet. Aqua Cones cost $12.50 for six or $20 for 12.
WaterWells
are a new product from Australia where professional landscapers plant
trees in large wells to ensure that nutrients and water get to the roots
without running off. WaterWells give your plants the same benefit without
all the digging. They hold water, fertilizer and mulch to prevent wasteful
runoff, keep out weeds, and protect trees from the string trimmer. They
"unzip" for use on both new and established plantings. Made
of recycled plastic, they are excellent for slopes and poor soils. Water
Wells cost $19.95 for a set of three and measure 19 inches in diameter
and 7 1/2 inches high.
Self-watering
patio gardens, window boxes and hanging planters use water effectively
A built-in reservoir holds up to four gallons of water and fertilizer
so plants get all the moisture and food they need, easily and consistently.
Self-watering patio and hanging garden containers range in size and style
and cost from $14.95 to $59.95.
The Noodlehead
sprinkler has 12 individual nozzles that can be positioned independently
to direct water precisely where it's needed up to 15 feet away. It's especially
effective for watering irregular beds, and in windy areas since the nozzles
can be positioned to aim low, directly onto the soil. The Noodlehead sprinkler
is 3 1/4 inches in diameter and costs $19.95.
Gardener's
Supply has offered the Hydro-Grow soaker hose system since 1984, and its
easy, efficient performance has made it a customer favorite. A new mini
soaker hose is perfect for perennial beds. It's available in 50 and 100-foot
lengths and comes with end caps and hose fittings. The mini soaker hose
is less bulky and perfect for weaving through raised beds or perennial
gardens.
Soaker hoses
work most effectively on relatively level ground, for runs up to 100 feet.
If lack of rainfall is a problem in your area, or if you are often on
water rationing, a soaker hose is a great solution. The Hydro-Grow hose
costs $19.95 for 50 feet or costs $37.95 for 100 feet. The mini soaker
hose costs $11.95 for 25 feet.
Commercial
landscapers rely on Terra-Sorb to protect plants in heat-stressed, drought-prone
areas like city parks and traffic medians. This nontoxic gel absorbs up
to 200 times its weight in water, and then releases it gradually as plants
need it. And because Terra Sorb is potassium-based instead of sodium-based,
it breaks down into fertilizer instead of soil-damaging salts. This environmentally-friendly
mix is offered exclusively by Gardener's Supply. Terra-Sorb costs $10.95
for a one-pound jar and $39.95 for a five-pound jar. One pound would cover
100 square feet in the garden, and one teaspoon is needed per gallon of
soil in containers.
To ensure that
you make use of all the rainwater that comes your way, a Rain Saver water
barrel can collect rain and roof run off. It's a heavy duty, 50-gallon,
recycled plastic barrel that has an angled, locking lid to catch every
raindrop while keeping out critters and kids. The Rain-Saver water barrel
costs $59.99, and the deluxe rain barrel costs $125 or $225 for two barrels
and a linking kit.
