Description of Trumpet Vine
The trumpet vine grows up to 10 meters tall and is an active, deciduous, woody vine memorable for the conspicuous orange flowers that are shaped like a trumpet and its reputation for being an invasive plant. It grows in forests, thickets, swamps and river banks and is also a popular occupant of parks.
Trumpet vine is grown without difficulty in many different types of soils. It is best planted in medium-rich soil with regular moisture in full sun or partial shade.
The plant has strong roots and aerial roots that form in 2 rows below the stem nodes.
The stem is covered with hairy aerial roots. Old stems become woody and thicken several centimetres in diameter. The bark of the mature vine is scaly and light brown.
Once the vine reaches a certain height, horizontal branches grow, moving away from the support in search of light and space. The leaves are 1 to 4 inches long and 0.5 to 1.5 inches wide, shiny green and inedible to herbivores.

Planting Trumpet Vine
Trumpet vines can be planted any time from early spring to late autumn but the best time to plant is early spring.
The trumpet vine flowers primarily in summer, but well-established plants sometimes flower in early spring and well into autumn.
How Much Water Do Trumpet Vines Need Per Day?
Although they like moist soil, trumpet vines require just a bit of watering for the whole season. Trumpet vines don’t need too much water, just 1 inch of water each week will suffice.
How much water do trumpet vines need? Trumpet vines don’t need daily watering.
The best way to tell if you need to water them more is to just feel the soil. When the soil is dry to a depth of 10 cm, then the flower needs water.
If you live in an area where it rains frequently, sometimes rain alone is enough to keep these gorgeous flowers hydrated.
In fact, if it rains more than that amount, this can pose a problem since their weekly water requirement is only 2.5cm of water. It is best to water trumpet vines with up to a gallon (3.8 litres) of water once a week.
Watering trumpet vines daily is not the best way to grow a healthy plant and can lead to many issues eventually. Trumpet vines should get only 1 inch of water once a week.
However, if the soil is getting dry too fast where you reside, water the trumpet vines half an inch two times a week just to increase the watering frequency. This ensures that the soil is kept moist at all times.
In any case, trumpet vines are somewhat tolerant to lack of water for long periods, therefore, this may not be necessary in every case.

How Do You Water Trumpet Vines?
There’s a correct way to water trumpet vines to get the best out of them:
Trumpet vines should be watered at the base to ensure their roots receive moisture. Use a watering can or drip hose for this job.
Do you want to measure how much water trumpet vines need? If you are making use of a watering can make sure to provide 1 gallon (3.8 litres) of water every week but if you are using a soaker hose instead, a 15-minute watering session once a week should be enough for your trumpet vine.
Now, you should not water a trumpet vine overhead as this can bring on fungus because the leaves never dry completely. Also, because they have a deep root system, watering trumpet vines from above is not very effective.
Rather, target the water at the base of the plants so that it can soak deep into the soil and get as close as possible to the roots.
Depending on the amount of sunlight they receive, watering trumpet vines from above can also cause your vine to be attacked by powdery mildew. To prevent this from happening, provide water close to the ground.
Do Trumpet Vines Like Wet or Dry Soil?
Trumpet vines are like moist soil but the soil must not be soaked or flooded because they do not tolerate wet conditions very well. If they remain in waterlogged soil, a host of fungal diseases will immediately attempt to attack your trumpet vines.
Trumpet vines are drought tolerant but will become stressed if water is not adequately given and may not grow to their full height if left in dry soil for a long time. In addition to this, buds take a long time to form and open.
Just be sure to strike a good balance between dry and moist soil, and be careful not to go to the extreme, either way.
Can You Overwater Trumpet Vines?
Trumpet vine plants can get overwatered very easily. Keep in mind that although trumpet vines prefer moist soil, they do not tolerate overly wet soil.
Soil that is too wet or saturated does not pass the “pinch test”. The pinch test involves you squeezing a little bit of soil between your thumb and forefinger then if water drops out, it means that the soil is too moist.
You should use the pinch test to check if the soil is suitable for your trumpet vines. Root rot is a serious complication in trumpet vines that have been given too much water–it prevents the roots of the flower from delivering water and other essential soil nutrients.
Root rot is not the only disease that can develop in overwatered trumpet vines. If these plants keep growing in moist soil, they can also develop powdery mildew, grey mould, and other fungal diseases.
To avoid these problems, only water the plants when the soil is dry to the touch and provide only an inch of water per week unless you live in an extremely hot climate.

How Do You Know If Trumpet Vines Need Water?
Apart from the pinch test, the best way to tell if trumpet vines need water is to poke your finger to a depth of 10cm below the soil surface. When it feels completely dry, you will know that it’s time to give them some water.
To keep your hands from getting dirty, you can use a soil moisture meter to check the soil moisture at this same depth. When the soil is dry to a depth of 10cm, your trumpet vines need water.
Alternatively, grab a handful of dirt from the surrounding area and press it into a ball. If the ball keeps its shape, then there is no need to water the trumpet vines that day but if it breaks up immediately the soil is dry enough to water again.
If the leaves start to fall off or wilt, this is a sign that the plant needs more water but you shouldn’t let it get to this point.
Do Trumpet Vines Require Lots of Water?
In answering ” how much water do trumpet vines need?”, we said that they only need a little water, approximately 1 inch of water every week. Trumpet vines prefer moist soil, but they are drought-tolerant flowers that thrive even when provided with little amounts of water.
