Last Updated on February 23, 2023 by Mattias

Growing vegetables is a healthy and reassuring way to have control over your diet. Studies have shown that self-grown vegetable plants are likely to contain much more nutrients than store-bought ones. 

If you have decided to grow your vegetables, you should know that proper watering is the most important part of their development. 

Not sure how often to water new vegetable plants? Keep reading this article to find out because you definitely don’t wanna get off on the wrong foot.

How Often To Water New Vegetable Plants?

New vegetable plants are young with weak root zones, and unlike fully grown plants, they need more water to support their active growth. To say the least, you should water your new vegetable plants three times a week with an inch of water. However, like most plants, the soil is the most influencing factor that determines your plant’s watering needs overall; thus, always feel its moisture before going ahead with the task. 

Regarding vegetable plants, their type may vary from leafy green, cruciferous, and root vegetables to allium and edible plant stems. You have a bunch of options to plant in your home garden.

One thing they all have in common is their attention-worthy watering needs. Growing vegetables may be harder than growing other plants because they need proper fertilizers and extra care during their harvest season.

Do New Vegetable Plants Need More Water Than Fully Grown Vegetables? 

It is a common question that gets asked often. Yes, your newly planted vegetable plants will need more water than fully grown ones. That’s because your young plants are in their growing stages and need extra water to grow.  They have weaker root systems that aren’t properly established in the foundation yet, which hinders their ability to absorb water from the soil as remarkably as adult plants. They also need more water to assist with flower and fruit bloom.

How Much Water Does a New Vegetable Plant Need?

Using the right amount of water is also crucial to a plant’s growth. Now typically, your newly planted vegetable plants need an inch of water per week, but the decision mainly lies on the soil’s moisture. As your plants mature, you’ll need to adjust your watering schedule accordingly.

You should water the seedlings once a day for the first 3 weeks as they are totally incapable of absorbing the water themselves, and they rely on you for their entire supply. After the initial period, you should decrease the water frequency and only water young plants 2-3 times a week.

In the following months, decrease the frequency and focus on density instead. You’ll need to water the plants deeply so that the soil is fully soaked and the roots have received essential water. Fully grown plants are mostly self-sufficient, but you’ll need to water them more often in the harvest season.

When Is The Best Time to Water New Vegetables?

You must wonder when it is best to water your new vegetable plants. Early morning is generally considered the best time due to several reasons. Primarily, when you water your plant’s first thing in the morning, it will give them a better chance to absorb all the water and remain filled throughout the day.

You can say that It will give your plant energy to survive the day’s heat. If you somehow skip the first watering session, late afternoon will also be a good alternative because weather conditions will have returned to a hospitable state.

Considering that temperature tends to increase during mid-day and early afternoon, if you water plants during that time, most of the water will evaporate, and your leafy friend will have little water to rely on. 

This time is also recommended because the plant will get its essential water while the excess water evaporates well before evening. This will also save the plant from standing in waterlogged soil.

Despite the time frame, focus on the soil dryness before watering if the soil surface is visibly cracked, crumbly, and dry. Only then you should go ahead with the watering. Remember that damp and moist soil doesn’t need to be watered.

Does The Type Of Soil Affect Vegetable Plant’s Watering Needs?

The soil type you have selected will also determine how often to water new vegetable plants. If we talk about container plants, their potting mix is designed in a way that it’s well-draining. This means that water will dry out quicker, and your plant will need to be watered more often. 

As for in-ground garden plants, if you have planted them in sandy soil because of their infamous drainage system, they’ll require large amounts of water. Vegetable growth will only be successful if you diligently fertilize and water the soil.

Meanwhile, vegetable plants in clayey soil will have firm anchorage and require little water. Unlike sandy soil, clay soil can hold water for longer and keep the plant content, so if your garden has clayey soil, you’ll need to water it less often.

How To Water New Vegetable Plants? 

Now that you know how much, when, and how often to water new vegetable plants, here’s how to water them. 

As mentioned above, deep root penetration is the general rule for a good watering. It is one of the reasons why gardeners are recommended to water plants right after light rain showers. The deeper the plant’s root system, the better the growth, and the key to getting a deep root system is dense watering.

After you have transplanted the seedlings, you’ll need to saturate each hole thoroughly, and when you water them after transplantation, make sure the water reaches the roots and drench them. A popular advice is to water the base of the plant at the soil level rather than going for the typical “top to the surface” way. Watering the leaves is useless because plants get nourishment from the roots anyway, so it is much better to water them directly. Not only that, but wet leaves can actually attract pests and diseases. 

If you have a small home garden, it would be a good idea to use a watering can, watering wand, garden hoses, or soaker hoses, as these options will enable you to water the top of the soil effortlessly. Meanwhile, drip irrigation systems and sprinkler systems may be a much better choice for large gardens.

Why Is Mulching Important For New Vegetable Plants? 

Mulching is a customary practice adopted by several farmers and home gardeners. It is a process of applying external material, i.e, mulch, to the top layer of soil. This mulch mostly consists of organic matter. Aside from enhancing the area’s visual appeal, it also provides several other benefits.

Mulching is important for new vegetable plants because it enables them to absorb and retain water efficiently. It preserves soil moisture for longer and prevents weed growth in your garden.

The area around your planted vegetables will most likely be filled with grass and other shrubs. When you water your in-ground vegetables in hot weather, these external growths will take up a big percent of water, and the plant itself will have little. You will be satisfied thinking that the plant is getting its adequate water supply. Meanwhile, it will suffer from the consequences of underwatering. 

Having mulch instead of grass will solve this problem, and your plant will be able to have quicker growth and healthier vegetables. Another benefit of mulch is that it provides nutrients to the soil and keeps it relatively cooler on hot summer days.

Tip: apply 2- 2.5 layers of mulch for better air circulation.

How To Know If You’re Overwatering Your Vegetable Plants?

One of the most common mistakes on any gardener’s end is overwatering. You can misjudge your plant’s needs and overwater them when they already have enough moisture. If you keep watering your plant without regard for the soil’s moisture and natural conditions, your plant is at risk of developing fungal diseases. Unlike mature plants that naturally resist mold and fungus, damping off can emerge if the young vegetable plant is left in soggy soil for too long. This disease can even kill your plant, so look out for the following signs, and if they are occurring on your plant, then cut back on water immediately.

• Yellowing leaves
• Brown tips
• Constant wet soil
• Root rot
• Yellow or brown limp on the fruit

How To Know If You’re Underwatering Your Vegetable Plants?

Lack of water is a major risk for seedlings and young plants. They are actively growing and thus require a steady amount of moisture. Even slight negligence on your part can result in them drying out or having slow, stunted growth. Underwatering a new vegetable plant is menacing because young seeds need to germinate, and they won’t be able to do so with less water. 

As for the seeds already germinating, they risk dying in case enough water is given.

We have listed some of the most common and easily noticeable signs of underwatering below, and if they are identifiable in your plant, then your immediate attention is needed.

• Drooping leaves
• Pulled away soil 
• Dry, crispy leaves with brown tips
• Wilted leaves
• Curled up leaves
• Leaf drop

As you can see, some of the signs are the same as overwatering. It is crucial to understand the difference between the two. You’ll either increase the water supply for your overwatered plant and unintentionally kill it, or you’ll stop watering your already thirsty and dried-out plant.

Examining the leaf’s texture can distinguish the wilting sign in either case. If they are wilting and dry to the touch, that’s a sign of underwatering, but if they are wilting and soft/squishy to the touch, that is a clear indication of overwatering.
