Garden Watering Basics You Should Know

How much water does your garden need?

Water, passionate well-informed gardeners, we are well aware of one simple rule of thumb. The rule of thumb, our vegetable plants need one inch (2.54cm) of water every day to produce a bountiful crop of fresh fruits and veggies.

For many rare thinking gardeners like us, this well-known rule simply creates a quandary. How much water is that anyway?

To make it easier to understand let us look at it another way. Think of your garden site requiring a minimum of one US gallon (3.79 liters) of fresh water, evenly distributed, over ten square feet (0.93 square meters) in your vegetable garden, each week of the growing season.

With that said, make watering our veggies easy and less stressful for not only our tomatoes, pepper, zucchini and cucumber plants, but we gardeners as well. Let us learn watering vegetable garden basics all beginner and master gardeners should know.

1. Reliable water source

Rainwater is best

Rainwater is without question the best and most cost effective means of watering our gardens. However, it is not always the most reliable water source for our veggies. There is really only one way, of accurately measuring rainwater so we can easily determine, exactly how much water our garden really gets each time it rains, or we use a sprinkler or irrigation system for that matter.

We, as serious minded gardeners with our water management issues, need to invest a little time and money in setting up a useful water measuring system, or rain gauge if you rather.


The importance of using more than one rain gauge

Rain gauge, weather you prefer to use a commercially available gauge, purchased at your local garden center, online store such as Amazon, or the simple small bowl or repurposed tin can rain gauge. All are especially useful when testing the coverage of a high-head sprinkler system, drip irrigation, misters, or soaker hose. This requires several rain gauges scattered throughout the garden to ensure even coverage across the entire garden site.

2. Watering vegetable garden frequently

Frequently watering our vegetable gardens effects the garden soil PH, for instance, acid rain contains high levels of sulfur. Subsequently over time, high levels of sulfur in the rainwater, Leeds to higher acidity levels in our garden soil. By the way, high sulfur levels in the air are due in part to the use of burning coal in electric power plants, and other industries such as steel and aluminum production.


City and county water departments, as you know filter our drinking water to remove harmful impurities. They also add disinfectants such as chlorine, to kill bacteria. Some cities use ozone or chloramines. growing numbers of municipalities are using reverse osmosis or activated charcoal water filters to disinfect drinking water. This filters significant numbers of beneficial minerals out of our water.

Disinfectants contain compounds including bromates, chlorites, chloramines and chlorine dioxide that are stressful to some of our favorite flower, fruit and vegetable plants. This is evident in plants that have absorbed chlorinated tap water and show signs of yellow or browned tips on their leaves. Tap water that is treated with chlorine can also negatively affect beneficial nematodes, and earthworms that help decompose humus, critical to good organic material rich garden soil.


Allowing chlorine to evaporate

It is a good idea, to let the water we use to water container plants. Stand overnight allowing the chlorine to evaporate before watering our vegetable, fruit and flowering plants. Generally, city water ranges from 5.5 PH, which is considered as soft water, too 8.5 ph (hard water), sweet water has a PH of seven point zero which is neutral, and neither acidic, or alkaline.


How watering affects soil PH

Check the Ph of your garden soil regularly, and make the necessary adjustments to keep your garden soil PH at say six to six point five for green leafy vegetables, tomatoes, zucchini, cucumbers, green beans, and five to five point five for blueberries, azaleas and other acid loving plants. Just remember check your garden soil PH regularly, your favorite plants requirements may vary with their particular needs, so make sure you provide your plants with all the nutrients and soil conditions they need to thrive, and reap a bountiful harvest this season.

3. When to water the garden

● After a good half-inch rain, our garden will not need additional watering for two or three days.

● When a heavy rain is in the weather forecast, put off watering your flower, fruit and vegetable garden one day before it rains.

● Frequent watering is essential when either planting our favorite flower and vegetable seeds, or transplanting tender seedlings.

● Seeds that do not receive the proper amount of water, (keep seeds moist) will dry out; causing poor seed germination, or not germinate at all.

● Seedlings not kept moist will certainly wither and die.

● On hot summer days, it is best to water vegetable plans twice a day. Once in the morning before the intense heat of the mid day sunshine, and the second watering, in late afternoon and early evening, so our vegetable plants will have time to dry before the sun goes down.
