How to Grow Passion Vine?

Growing a passion fruit plant is relatively easy if you live in a warm climate. Here are a few simple steps you need to follow to grow the passion fruit plant:

1. To grow the passion plant from seed, open the pods and clean and dry the seeds before storing them. 
2. Soak the seeds in warm water for 1 or 2 days. Remove the seeds that are floating in the water. 
3. Place the soaked seeds in a damp potting mix and seal the pot in a plastic bag to retain the moisture. Pro tip: you can use a heat mat to speed the germination process. 
4. Keep the soil moist throughout. Germination will occur in 15 to 20 days. 
5. Choose a location with bright sunlight and partial shade, and place the sprouts there. This will help with the best plant growth and blooms. 
6. Transplant the plant once it is large enough, with a set of leaves. 

In case you are directly sowing the plant outdoors, wait until the frost is over and the spring season has arrived.

2. Remove the leaves at the bottom of the cutting.
3. Dip around an inch of the cutting in the rooting hormone.
4. Fill a small pot with a well-drained potting mix and place the stem cutting in the soil around half to one inch deep. 
5. Lightly water the soil, cover the pot with a plastic bag, and make a couple of small slits at the top of the bag for air circulation. Ensure that the leaves do not touch the plastic bag. 
6. Place the pot in a shady, warm spot. Within a few weeks, the cutting will start rooting. 
7. When rooted, transplant the cutting into the soil. 

Another way to propagate the passion plant is by tip layering. Here are some simple steps that can be followed:

2. Place the vine tip into the ground. Ensure you remove any leaves and bumps to avoid bacterial problems in the soil. 
3. Place the part of the vine flat into the soil and cover it with soil. 
4. Tug on the vine in the spring season to see if it has rooted well. 
5. The vine is ready to be transplanted to your desired location.
