Eggplants grow best when they are watered once per week for 30–40 minutes with a soaker hose. The ideal amount of water for eggplants is 1 inch (2.5 cm) each week. If you are using a watering method other than a soaker hose, water until the top 6 inches (15 cm) of soil is moist. Then, water again once the top of the soil is dry. In very hot temperatures you may need to water eggplant more often, but eggplants thrive in hot sunshine and struggle if their soil is soggy. So, it’s better to provide a little less water instead of too much.

How Much Water Do Eggplants Need Per Day?
Eggplants will grow weak, shallow roots if they are watered every day. Instead, it’s better to soak the ground to a depth of 6 inches (15 cm) once per week. Then, allow the soil to dry out before watering again. 1 inch of water (2.5 cm) is ideal for eggplants. If they receive this amount through natural rainfall, you can skip watering for the week.
- Eggplants need 1 inch (2.5 cm) of water every week.
- It’s better to water eggplants once weekly instead of daily.
- Daily watering can lead to weak eggplant roots and rotting fruit or leaves.
Use organic mulch to help retain soil moisture for your eggplant between waterings. Wood mulch, shredded leaves, or grass clippings as a layer of mulch will reduce the need for frequent waterings. In the long term, this will result in perfect eggplant fruits to enjoy.
How Do You Water Eggplants?
It’s best to water eggplants with a soaker hose on a low setting for 30–40 minutes once per week. Check the soil after watering to ensure it is moist to a depth of 6 inches (15 cm). If it’s dry at this depth, continue watering for a while longer. You want the soil to get a thorough moistening every week to develop strong, deep eggplant roots. For this reason, you should avoid drip irrigation which often struggles with reaching deep soil.
- Soak the soil thoroughly by running this soaker hose for 30–40 minutes once each week.
- Your eggplants are thoroughly watered when the soil is moist at a depth of 6 inches (15 cm).
- Avoid frequent smaller doses of watering as that promotes shallow roots.
- Make sure not to get the leaves and fruit wet when watering eggplant.
You can also use a watering can to water deeply. Just be sure to avoid watering the foliage of the plant. Getting the leaves overly wet can result in fungal issues. So, it’s best to avoid overhead watering whenever possible with eggplants.
Do Eggplants Like Wet or Dry Soil?
Eggplants prefer well-moistened soil, but grow poorly in overly wet soil. Additionally, most varieties of eggplant prefer warm soil and have a low tolerance for cold soil. Eggplants are fairly hardy plants and can tolerate mildly wet to mildly dry soil for a short time.
- Eggplants prefer consistently moist soil but can tolerate wet or dry soil for brief periods.
- Make sure you have a consistent warm soil temperature for your eggplants.
- Soil that dries out between waterings is better for eggplants than soggy soil with standing water.
Planting eggplants in sandy soil helps to ensure adequate drainage and avoid waterlogged soil. Additionally, if you plant eggplant in containers, you want to make sure you have good drainage holes. Lastly, consider getting this moisture meter to track the moisture of your soil.
Can You Overwater Eggplants?
Eggplants can easily become overwatered. The first warning sign of overwatering is if your soil is waterlogged or has pools of standing water. Eggplants don’t like soggy soil. These conditions lead to fungal diseases such as root rot. If water pools on top of your soil, then you have almost certainly overwatered.
- You have overwatered your eggplant if there is standing water on the soil surface.
- You’ll know you have an overwatered eggplant if it begins wilting, losing leaves, or has signs of fungal infection.
- Cool, rainy conditions reduce eggplant watering needs. So, adjust your watering schedule with the weather.
- Install this rain gauge in your garden to see if your eggplant is getting 1 inch (2.5 cm) of water per week from rain alone.
Be on the lookout for cold temperatures and wet weather conditions. If it’s raining a lot and the air is cool, your eggplant may already be getting plenty of water. Adjust your watering so that you’re maintaining moist soil without drowning your plant.
How Do You Know If Eggplants Need Water?
Eggplants have similar signs of underwatering to other plants: yellowing leaves, wilting, and stunted fruit production. There’s even a long-term negative issue where underwatered eggplants produce bitter fruits.
- Water eggplants whenever the soil around them is dry to the touch.
- Use a moisture meter to better track the soil moisture around your eggplants.
- Underwatered eggplants are prone to wilting and leaf yellowing.
One of the easiest ways to tell if your eggplant needs water is to touch the dirt around it. If the soil is dry to the touch, watering it would be an excellent choice. You can also use a moisture meter to tell when the soil moisture is too dry as soon as possible.
Do Eggplants Require Lots of Water?
Eggplants don’t require as much water as other vegetables. As long as you provide deep watering once per week, you have nothing to worry about. Here are some key tips to help you grow perfect eggplants with the right watering schedule:
- Eggplants need 1 inch (2.5 cm) of water every week.
- Water eggplants once weekly for the best results.
- You will know your eggplants are properly watered when the top 6 inches (15 cm) of soil are moist.
- Run a soaker hose at a low setting for 30–40 minutes to water your plants properly.
- Avoid overhead watering since this can cause eggplant fruit and foliage to rot.
- Water your eggplants whenever the soil is dry to the touch.
