fruit plant can grow easily from vine cuttings. Here is a vine cutting
that started to sprout roots with no water, no soil, no hormones. This
piece is placed on a kitchen table with warm filtered sun.
Plant the vine in good potting soil only 1 to 2 inch deep. Water once every two week and let the soil dry up. With filtered sunlight and warm temperature, the vine will grow root first. Once the root is established, new vines will sprout from the nodes. If the vine is planted sideways, it will still grow well. There is a higher risk of rotting. If the vine is planted upside down, it will be stunned for several months. Roots will sprout from the top. If you see this problem, pull the vine out and plant the other way.
Roots can grow from any surface of the
plant. This photo shows a root growing in the middle of a surface and
perpendicular to the surface. These roots are intended to anchor to walls,
tree bark, post, etc. The roots can dry up without any harm.
This is a dramatic picture showing a small pot and a big top. It is common to have the plant tip over or sag due to the weight of the vines. Use a pot no larger than 25 gallon. This plant is very efficient because it can grow root on any surface. It can absorb water and nutrient on any surface. It can also utilize low light or partial shade. Be careful when the plant is moved from low light to full sun, the vine can sunburn easily. In order to fruit, the plant has to grow over 10 pounds overall weight. It has to get at least half day sun, full day of direct sun is better. It needs low nitrogen and high phosphorus in the soil. On many plants, the flowers will drop unless they are cross pollinated.
