How Much Water Do Trumpet Vines Need?

Trumpet vines need 1 inch (2.5 cm) of water provided once per week. Although they like moist soil, trumpet vines only need minimal water throughout the season. The best way to determine if more water is needed is to simply feel the soil. If the soil is dry 4 inches (10 cm) below the surface, your vine needs water. Depending on your geographical location, sometimes rainfall alone is enough to supply adequate water to these beautiful vines.

How Much Water Do Trumpet Vines Need Per Day?

Trumpet vines don’t need daily watering. In fact, this may be a somewhat difficult task since their weekly water requirement is only 1 inch (2.5 cm). It’s best to water trumpet vines with 1 gallon (3.8 liters) of water once per week.

• Watering trumpet vines daily is not the best way to grow a healthy plant.
• Provide 1 inch (2.5 cm) of water in a once-weekly watering.
• If the soil dries out quickly where you live, water your trumpet vines half an inch, twice a week.

If you live in an area where the soil dries out quickly, however, you can opt to split your trumpet vine’s inch of water into two separate waterings. This ensures that the ground always stays moist. However, these evergreen vines are pretty drought-hardy, so this may not be necessary in all cases.

How Do You Water Trumpet Vines?

Trumpet vines should be watered at the base to make sure that their roots receive moisture. Use a watering can or soaker hose for this job. If you are using a watering can, provide 1 gallon (3.8 liters) of water per week. If you are using a soaker hose, 15 minutes of soaking once per week should be enough for your trumpet vine.

• Trumpet vines should be watered at the base.
• If watering by hand, give your trumpet vine 1 gallon (3.8 liters) of water once each week.
• If you are watering with this soaker hose, run the hose for 15 minutes to provide adequate water to your vine.
• Do not water a trumpet creeper from the top—this can cause mildew.

Because they have a deep root system, watering trump vines from the top isn’t very effective. Depending on how much sunlight they receive, watering them from the top may also result in your vine being attacked by powdery mildew. To avoid this, provide water at the soil level.

Do Trumpet Vines Like Wet or Dry Soil?

Trumpet vines like moist soil, but will not tolerate soggy conditions very well. A host of fungal diseases will immediately try to attack your trumpet vines whenever they are overwatered. Similarly, a different set of problems can occur if the soil becomes too dry.

• Trumpet vines prefer moist soil, but not wet conditions.
• Soggy or waterlogged soil will cause your vine to be attacked by fungal diseases.
• Trumpet vines are drought resistant but will become stressed if enough water is not provided.

Even though trumpet vines are somewhat drought resistant, they may become stressed and fail to grow to their full height if left in consistently dry soil. It may also take the buds a long time to open and bloom. For this reason, make sure you strike a good balance between dry and moist soil, making sure you do not go too far in either direction.

Can You Overwater Trumpet Vines?

Trumpet vine plants can easily be overwatered. Keep in mind that although they prefer moist soil, trumpet vines will not tolerate soggy soil. Soil that is saturated won’t pass the “pinch test.” This consists of squeezing a bit of the soil between your thumb and forefinger. If moisture pushes out, or the soil actually drips water, it is far too saturated.

• Trumpet vines can be overwatered.
• Use the pinch test to determine if the soil is soggy.
• Root rot is a serious concern with overwatered trumpet vines.
• Fungal diseases may take hold if trumpet vines are growing in wet soil.

Trumpet vine roots need oxygen. If your soil is overly saturated with water, it prevents vine roots from bringing in oxygen. Additionally, your trumpet vines are in danger of root rot if their soil is too wet. Vines grown in wet soil may also develop powdery mildew, gray mold, or other fungal diseases. To avoid these problems, only water when the soil feels dry and only provide 1 inch (2.5 cm) of water per week unless you live in a particularly hot climate.

How Do You Know If Trumpet Vines Need Water?

The best way to tell if trumpet vines need water is to push your finger into the dirt to a depth of 4 inches (10 cm). If it feels dry all the way down, it’s time for some water. If you don’t want to get your hands dirty, you can use a soil moisture meter to check the soil moisture at this depth.

• When soil is dry at a depth of 4 inches (10 cm), your trumpet vines need water.
• You can poke your finger into the soil to determine if your plants need water.
• For a precise indicator of soil moisture, use this moisture meter to determine if your trumpet vines need water.

Another great way to determine if your trumpet vines are thirsty is to grab a handful of soil from the surrounding area and squeeze it into a ball. If the ball retains its shape, there is no need to water your trumpet vines that day. If it immediately falls apart, then the soil has become dry enough to justify a watering.

Do Trumpet Vines Require Lots of Water?

Trumpet vines prefer moist soil, but they are drought-resistant plants that thrive on small amounts of water. To successfully water your trumpet vine:

• Give your trumpet vine 1 inch (2.5 cm) of water per week.
• 1 gallon (3.8 liters) of water per week is sufficient if you are watering with a watering can.
• 15 minutes of soaking with a soaker hose provides a trumpet vine with its weekly watering needs.
• When the soil is dry at a depth of 4 inches (10 cm), your trumpet vine needs water.
• Natural rainfall provides enough moisture for most trumpet vines.
• The best way to decide if your trumpet vines need water is to feel the soil.
• Overwatered trumpet vines will develop diseases, struggle, and die.

Trumpet vines will respond well when cared for in this way. You’ll be rewarded with a healthy growth of green leaves, as well as white, orange, or yellow flowers, depending on the variety of trumpet vine you’ve chosen to grow.
