Unfortunately it seems that since my address is not California they do not appear for me, I guess the providers do not ship there. Very sad.

Asexual Propagation
Cuttings
Propagating passion fruit plants through cuttings is an effective way to generate genetically identical offspring. This method requires less time than growing plants from seeds and generates plants with a shorter juvenile phase. Cuttings can grow into healthy plants in just a few months. Balancing humidity and air circulation is critical for successful propagation by cuttings. Such balance prevents pathogen growth and preserves substrate moisture to promote root development at the bases of cuttings.

For propagation by cuttings, a healthy, disease-free plant actively producing fruits should be selected as the source of plant material. Ideally, the plant should be assessed for viruses before propagation and discarded if infected. Taking cuttings from branches that are blooming or fruiting should be avoided. Cuttings with flower buds consume their energy in reproductive growth rather than in rooting. Selecting one-year-old wood cuttings with new growth is recommended, as these parts are more likely to root successfully.

Before obtaining cuttings, garden clippers should be sanitized in a 10% chlorine solution to prevent disease transmission. Proper cuttings for propagation are obtained by cutting a stem segment at a 45-degree angle just above the bottom node because this method increases the surface area for root development. To encourage root growth, the cuttings should have two to four nodes (Figure 6), tendrils removed, and leaves cut in half, except for the newest leaves. Dipping the cuttings into a fungicide solution before propagation prevents disease development. Additionally, applying rooting hormones (available in powder, liquid, or gel forms) evenly on each cutting’s end surface can significantly promote root development.

To plant the cuttings, fill a pot or propagation tray with a peat-moss-based potting mix containing perlite, which will provide ideal drainage and moisture levels (Figure 7). Each cutting should be planted in a hole with a depth of 2 to 4 inches (5 to 10 cm), with the angled cut end pointing down, gently packing the soil around it to eliminate air pockets. The substrate needs to stay moist but not oversaturated. The plants should be placed in a high relative humidity environment with temperatures around 85°F (29°C) and should receive indirect sunlight. Propagation boxes with clear covers are ideal for propagating passion fruit cuttings (Figure 7). To avoid disease incidence that may occur in humid conditions, spray the cuttings with fungicide every week. It is important to check the cuttings for new leaf growth and root development every two weeks. Removing flower buds during rooting is also recommended to redirect resources towards rooting. After two to three months and under proper conditions, the cuttings should have developed roots, making them ready for transplant. New leaf growth in the stem is a good indicator of successful root establishment. A noticeable resistance when gently pulling the cutting also means that roots are likely ready for transplant. After verifying those two indicators, the cuttings can be transferred to a new pot with fresh potting substrate. This propagation method offers a consistent and effective way to obtain healthy plant material, ensuring the plants have the desired traits observed in the parent plant while shortening the juvenile phase.
