After perusing seed catalogs or retailer websites, deciding which vegetables to grow can be fun.

Seeds can be direct sown, but require a warm place to germinate, or plugs/plants can be purchased for instant impact. Vegetable gardens need a site that gets full sun, ideally 6-8 hours a day. Water is heavy, so site your plot near a water source for easy access.

Growing your own vegetables is a highly enjoyable and rewarding experience, though it does not come without effort. Watering is an unavoidable part of growing crops and many novice growers can find themselves wondering how often they need to water their plants.

Judging when to water plants, especially vegetables as many crops are very hungry plants, can be tricky. The regularity of watering is admittedly highly variable and can range from not at all, to every few weeks, to every day, but there are methods of helping you judge how often is often enough. By keeping track of the weather, working the soil to hold more moisture, watering deeply, and regularly checking the moisture levels in the ground, you can make a more informed decision on how often you should water a vegetable garden.

I worked in several large vegetable gardens during my time as a professional gardener and watering could potentially take up many hours a day, especially during the summer. You had to be organized, know the crops you were working with, and make judgement calls about what needed to be watered when. I was not always lucky enough to have irrigation systems and lots of the watering had to be done by hand, so that was where good monitoring and planning was essential.

How often do you water a vegetable garden?

soil type. The temperature and level of natural rainfall will be the main outside factors that dictate how often a vegetable garden needs watering.

The type of soil is a factor as a sandier soil will drain quicker than other soil types and require more regular watering. This can be combated by adding organic matter or compost, either incorporating it into the soil or on top as a mulch, which will improve the ability of the soil to hold onto moisture and make it available to roots for longer.

It tends to be thought that most vegetables require an inch or two of water each week. During wetter periods it means you will not have to water at all, while on the sunniest days of midsummer you may need to be out there every day or two watering plants in hot weather. It is important to track the weather and keep an eye on the forecasts to help guide your watering decisions. You could also get a rain gauge, such as this outdoor rain gauge on Amazon, as well as try to collect as much natural water as possible through rainwater harvesting.

The way you water will also dictate how often you have to water a vegetable garden. Correct watering can mean less regular watering, as vegetable plants will benefit more from deep and less frequent watering. A common garden watering mistake is to water lightly and only tickle the surface, that does the plants no good and also means you have to water more often. Giving the plants a good drink will drastically reduce how often you have to water, and you can further help retain more moisture in the soil by mulching the vegetable garden to reduce evaporation.

Knowing your vegetables is imperative to get the regularity of watering correct. There are some drought-tolerant vegetables that you can grow, but there are also lots of thirsty vegetables that want a lot of water. The likes of beans, beetroot, tomatoes and squashes need lots of water and lots of vegetables will need extra water when they are flowering or developing fruit. In particular, crops such as squash, pumpkins, zucchini and tomatoes want lots of water when the fruits are swelling and legumes such as peas and beans will develop better pods with regular watering.

Checking the moisture levels should be done regularly to see how much water is in the soil deeper than the eyes can see. You can do this with your fingers or a moisture meter, such as this long probe soil moisture meter available on Amazon, and this will help you make a more informed decision about whether to water. This can help prevent issues stemming from overwatering.

How often should you water a raised vegetable garden?

If you are growing in raised garden beds that can have an impact on the regularity of watering. Raised beds offer many advantages to gardeners and can be a great option for small vegetable garden ideas, however, they do need watering more often, especially during the warmer months. It is down to the fact that the elevated soil is liable to dry out quicker than soil in the ground, meaning you have to water more often. Water applied to a raised vegetable garden can run through the soil quicker than in the ground and leech away from the rootzone. It can leave plants more susceptible at times of drought. Adding compost or organic matter to the soil can help with water retention and mulching can help reduce evaporation.

How often should you water a vegetable container garden?

There are a great number of crops that work as vegetable garden container ideas, but any pots will need more checking and watering. Any of the best vegetables to grow in pots will need lots of moisture and the soil in pots can dry out very quickly, especially on hot days. 

While a twice-weekly check may suffice for a lot of the year, and a water every three or four days, this will ramp up during the summer. On very hot days you should check pots at least once or twice a day to see how dry the soil is, and water as required. 

When watering plants in containers, check the moisture level a few inches down and always water deeply. This is usually until you see water running out of the drainage holes in the bottom of the pot.

How often should you water a newly planted vegetable garden?

Newly planted vegetables and vegetable seedlings need watering more often than fully grown plants. As they do not have a fully developed root system they cannot find moisture deeper down and their roots can quickly dry out if the surface gets baked. 

Any young vegetable plants that have been recently planted, or transplanted seedlings, need to be checked on a daily basis and well-watered as required. During the hottest months, this could potentially be once, or even twice, a day to ensure these newly-planted vegetables survive.
