How to Grow a Pink Trumpet Vine in a Pot

Fill a 5-gallon container with an organically rich, well draining potting mixture. Utilize a container that drains or the plant will develop root rot. Water the potting mixture before planting the vine to settle the container’s soil.

Remove the pink trumpet vine from its pot. Inspect the roots for signs of wrapping. Pull the wrapping roots gently apart using your hands to promote healthy root growth.

Dig a hole in the center of the pot using your hands or a hand trowel. Create a hole that is large enough to hold the pink trumpet vine’s root ball. Make sure the hole is no deeper than the vine is presently growing.

Place the pink trumpet vine inside the hole. Cover the hole with the potting mix. Firm the soil around the vine using your hands.

Grow the vine in a sunny location for the most blooms. Place the containerized pink trumpet vine next to a trellis, arbor or other object it can use for support. Situate the container approximately 12 inches away from the support object.

Tie the vine’s stems to the support object to encourage it to entwine. Use twine, survey tape or landscaper's ties to tie the stems to the support. Apply the ties loosely around the pink trumpet vine’s stems and the support object.

Water the pink trumpet vine after planting. Test the soil moisture by sticking your finger into the soil before applying additional water applications. Apply water if the first inch or two is dry. Water until it drains from the pot’s bottom drain holes.

Fertilize pink trumpet vines monthly throughout the warm, growing seasons. Use a blend low in nitrogen such as tomato fertilizer. Follow fertilizer directions concerning amounts and application.

Trim pink trumpet vines to control size and increase bushiness. Prune off long stems after the plant blooms. Use hand pruners to snip off the plant’s thin stems.
