There are many variables that influence how much water a garden requires. One key factor is soil type. Clay soil, for example, will not be as deeply penetrated by a 1 inch rain event as loamy or sandy soils.

Frequent, light waterings will encourage shallow roots that are dependent on you to supply their moisture needs. Ideally, you want your plants to develop deep roots that are able to absorb and retain water.

Plant Water Needs

Figuring out a good watering schedule can take some trial and error. Ask a nursery employee or someone else who knows gardening for insight, but also feel the soil with your fingers.

Avoid shallow surface watering that encourages root rot, and try to water in the morning or evening when any excess moisture doesn’t sit on the leaves all day. This reduces the risk of diseases taking hold.

Soil Type

The soil type in your garden will have a major impact on how much water your plants need. A soil test can help you identify the type of soil you have.

To test your soil, grab a handful of damp soil and roll it between your hands. Does it stick together or crumble? Does it feel sandy or gritty? A good soil is loamy and is a mix of sand, silt, and clay.


Choosing the right location for your flower or vegetable garden is key. Most vegetables need full sun to thrive. Make sure the area receives six hours of sunlight a day.

Watering during and immediately after a light rain shower is beneficial. It helps to replenish nutrients in the soil. But beware of overwatering as this can lead to puddles and waterlogged soil.

Rain Frequency

Plants need consistent watering to thrive. It is a good idea to use a timer on your garden hose or sprinkler, as this will reduce the amount of work you have to do.

Try to water your garden in the morning, rather than at night, as this will allow the foliage to dry quicker, discouraging fungal diseases. Mulching your garden will also help conserve moisture.

Size of Plant

Plants lose water through their leaves in warm weather and need to rehydrate through their roots. A gardener can minimize moisture loss by keeping the soil surface mulched.

If you are a beginner, resist the temptation to create an overly large garden. A smaller garden will be easier to manage and provide a satisfying harvest. If you are planting vegetables, wait until after the last frost date (this varies by location). Seeds should also be started indoors several weeks before transplanting.

Age of Plant

Newly planted plants and seedlings require water more frequently than established plants. Plants grown in containers also need more watering than those in the garden because they have smaller roots and are limited by their surface area to absorb moisture.

When watering, ensure that the soil has sufficient moisture before a hot day by checking the top few inches of soil with your finger or using a cheap soil moisture meter. Avoid splashing the leaves of young tender plants in hot weather to prevent scorching.

Type of Plant

It is important to know what kind of plants you want in your garden. Vegetables are great if you have a lot of space, but flowers can make any garden more beautiful.

Be sure to plant near a water source, so you can easily water your plants without lugging the hose around the yard. Also, consider using a gentle spray instead of blasting the soil with water.

Drought Resistant Plants

Many vegetables thrive in dry conditions. However, new plantings still require regular watering until they establish roots.

Vegetables that flower and produce fruit have higher water needs than leafy greens. The bigger the fruit, the more water they need.

It is recommended to use a long hose when hand-watering. This allows for deeper water penetration. Aim to saturate the soil down to 5 or 6 inches.

Watering Frequency

Watering frequency is dependent on many factors such as soil, weather and season. As a general rule, ornamental gardens need about an inch of water per week.

When you water, use a soaker hose or low-pressure garden hose to ensure that water reaches the roots. Avoid watering in the heat of the day when evaporation occurs faster. Also, avoid wetting the leaves which helps spread some diseases.

Overwatering Warning Signs

Misjudging how often to water a garden can lead to overwatering, which deprives roots of oxygen and slows growth. To avoid overwatering, plant in well-draining soil and use a moisture meter to check the soil’s moisture levels.

The amount of watering required varies by plant type, with leafy greens needing less than fruit vegetables. The weather also plays a role, with rainy conditions reducing the need for watering.
