The biggest need of Dutchman’s pipe vine care is plenty of water. Do not allow the soil to dry out completely when caring for pipe vines in containers. Plants in the ground will also need supplemental watering.
You can also use regular plant fertilizer mixed with the water to supply it with more nutrients. Use fertilizer two to three times during the spring and summer season.
Prefers a well-drained loamy soil, rich in organic matter, in sun or semi-shade[1, 200], but succeeds in ordinary garden soil
In the summertime, after the vine is done flowering, you have an opportunity for more intensive dutchman’s pipe pruning. At this time, you can cut back the shoots and prune back some of the old growth to the ground. This helps make the plant a little heartier for the next season.
