Many people ponder how to water a garden. They may struggle over questions such as, “How much water should I give my garden?” or “How often should I water a garden?” It's really not as complicated as it seems, but there are some things that should be considered. These include the type of soil you have, what your climate or weather is like, and the types of plants you are growing.
When to Water Gardens
“When and how often should I water a garden?” While the general rule of thumb is about an inch or two (2.5-5 cm.) of water each week with deep, infrequent watering as opposed to the more frequent shallow watering, this really depends on a number of factors. First, consider your soil. Sandy soil is going to hold less water than heavier clay soil. Therefore, it's going to dry out faster while the clay-like soil will hold moisture longer (and is more susceptible to overwatering). This is why amending the soil with compost is so important. Healthier soil drains better but allows for some water retention too. Applying mulch is also a good idea, reducing watering needs. Weather conditions determine when to water garden plants as well. If it is hot and dry, for example, you'll have to water more often. Of course, in rainy conditions, little watering is needed. Plants, too, dictate when and how often to water. Different plants have different watering needs. Larger plants need more water as do newly planted ones. Vegetables, bedding plants, and many perennials have more shallow root systems and also require more frequent watering, some daily -- especially in temps over 85 degrees F. (29 C.). Most container plants need watering on a daily basis in hot, dry conditions — sometimes twice or even three times a day. When to water gardens also includes the time of day. The most suitable time for watering is morning, which reduces evaporation, but late afternoon is okay as well -- provided you keep the foliage from getting wet, which can lead to fungal issues.
How Much Water Should I Give My Garden Plants?
Deep watering encourages deeper and stronger root growth. Therefore, watering gardens about 2 inches (5 cm.) or so once a week is preferable. Watering more often, but less deep, only leads to weaker root growth and evaporation. Overhead sprinklers are often frowned upon, with exception to lawns, as these also lose more water to evaporation. Soaker hoses or drip irrigation is always better, going straight to the roots while keeping foliage dry. Of course, there's the old standby—hand watering—but since this is more time consuming, it's best left for smaller garden areas and container plants. Knowing when and how to water a garden correctly can ensure a healthy growing season with lush plants.

FAQs
Water slowly, deeply, and infrequently. Avoid a quick splash that can promote shallow rooting, leading to poor drought tolerance. Water in the morning to allow wet foliage to dry quickly in the morning sun. Morning watering also ensures the plant is fully hydrated as it goes into the hottest part of the day.
What is the proper way to water a garden? ›
DO direct water at the base of a plant and avoid wetting foliage, which invites fungus. Also, you'll lose less water to evaporation and, since you're applying water directly to the root zone, the water will be readily available to the plant roots. DON'T water from overhead.
What is the best watering schedule for garden? ›
Quick facts. Water your garden so that your plants always have enough moisture. On sandy, well-drained soil, you may need to water twice a week. For soils that hold moisture, such as heavier clay soils, or loamy soils rich in organic matter, watering once a week is fine.
How many minutes should you water a garden? ›
How Long To Water Your Garden. Adjust your watering schedule based on specific plant needs and the seasons. In the summer, I either water with a slow drip for 1 hour every three days or 30 minutes every day. In winter, I might go a month or more without watering.
Should I water my vegetable garden every day? ›
Ideally, you should water an in-ground bed 1 to 2 inches a week, while a raised bed may require more water per week. Feeling the soil frequently is the best way to gauge when a raised vegetable bed needs watering.
Should I water my garden every day in hot weather? ›
During extremely hot weather (daytime temperatures above 90F and nighttime temperatures above 70F), try to water daily or every other day. In a 10x10-foot garden, this would mean giving your plants 8 to 9 gallons of water each day.
Should I water garden every day? ›
A good general guideline when it comes to watering your plants is an inch of H2O per week, either by rain or watering; in arid climates, it is double that. In hot weather, vegetables need even more water, up to about ½ inch per week extra for every 10 degrees that the average temperature is above 60 degrees.
How often should I water my tomato plants? ›
Soil that contains a lot of sand doesn't hold water well and dries quickly. Because of this, tomato plants growing in sandy soil may need to be watered more often, about every three or four days. Clay soil, on the other hand, holds water well. Plants growing in clay soil usually only need to be watered once a week.
Should you water garden morning or night? ›
Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.
How much water does a garden need per day? ›
For vegetables in the summer, we recommend applying about 1 inch of water over the surface area of the garden bed per week. That is equivalent to 0.623 gallons per sq ft. Using that rate, a 32 sq ft bed requires 20 gallons of water per week.
The best way to determine whether your garden is getting enough water is to feel the soil. If the surface of the soil is hard and cracked, your garden probably needs more water. However, you should really investigate how the soil feels below the surface to make sure.
How often should you water a garden in the summer? ›
During really hot weather, water your vegetables at least two to three times a week. Watering the garden deeply is critical. The water must go down, down, down to encourage deep roots and get away from the hot soil surface.
Can I water my garden too much? ›
Plants growing in soil that is too wet suffer from a lack of oxygen which leads to the death of roots and a loss of vigor in the plant. Stunted slow growth with yellowing leaves is a symptom of over-watering. Plants may suffer from leaf scorch or leaf burn.
What vegetables should be watered everyday? ›
Because the top few inches of soil dried out quickly, shallow-rooted vegetables such as cucumbers, spinach, cabbage, celery, corn, onions, leeks, carrots, broccoli, radishes, and Brussels sprouts will need frequent watering in hot weather or soils that are light on humus or compost.
Which vegetables require the most water? ›
Beans, corn, squash and cucumbers are the most water-needy vegetables. Tomatoes need plenty of water when they're young, but less water when fruits are ripening.
How much water is 1 inch of water? ›
But what is an inch of water really? To determine this, we have to go back to the basics of geometry to measure area and volume. However, a few measurements will always remain the same. Therefore, an “inch of water” is 0.62 gallons per square foot of garden area.
Is it better to overwater or underwater garden? ›
Usually underwatering a plant is less damaging than overwatering, which can cause additional problems like root rot and other diseases. But of course, if a plant is too dry it can shrivel up before you even realize it.
Should you water your garden from the top or bottom? ›
Promotes Healthy Roots
Bottom watering makes your roots work for their water source. Instead of being “fed” the water, they are having to bring the water up to them. This promotes healthy and stronger roots in the long run. This technique also helps your plant's roots grow downwards.
Should you wet the leaves when watering plants? ›
You can't prevent rain, but during dry periods when you need to water, don't simulate rain by using a sprinkler. Instead, use a soaker or drip hose that directs water into the soil rather than onto leaves.
