A good life expectancy for passion fruit vines is five to seven growing season due to their high susceptibility of root diseases. Propagating a passion fruit vine is possible and actually preferred over growing passion fruit from a seedling. Propagating a vine means you cut a vine from an existing passion fruit and transplant it to new soil. This is a process that requires patience and practice.
Cut a healthy vine stem from an existing passion fruit vine with a pair of sharp pruning scissors at least 1 inch below the lowest node in the stem. A node is a small bump or nodule on the stem that rests between the trunk of the vine and the leaves on the stem.
Place the vine into a container filled with fresh water until you can begin the propagation process. This prevents the wound from infection or from drying out.
Remove the vine stem from the water and cut it at a 45-degree angle just below the lowest node in the stem. Again, a node is the small bump or nodule on the stem.
Remove the lower leaves from the vine stem by pulling them off at the stem with your fingers.
Pour a cup of rooting hormone complete with a fungicide into a sealable plastic bag. Place the bottom of the stem into the bag and cover the stem in the powder. Remove the stem from the bag. Do not get the powder on any of the leaves or on the upper stem. Only cover the portion below the first node.
Place a 1-inch layer of unprocessed sphagnum moss in the bottom of a clay pot. Mix equal parts of peat, vermiculite, perlite and potting soil together and fill the clay pot three-quarters full with the mixture.
Press the vine into the soil until the first node rests just above the soil level.
Mist the vine daily with a spray bottle of fresh water until the vine is ready for transplant to the outside. Place the potted vine outside in a shaded area if you have at least two months before first frost. if needed, take the pot inside and place it near a window where it will still get shade for most of the day. After one to two months, you will notice new leaves forming on the vine. This is an indication the vine is ready for transplant into the ground outside.
