Why graft chili plants? I’ll tell you why – because you can grow multiple types of chilis on one plant, that’s why! In horticulture, grafting is the act of combining plant parts through tissue regeneration. It is done by putting a part of one plant into or on a branch, root, or stem of another (stock). It is completed so that they will be joined together, and they will persist in growing. Although it’s one of the most widely used vegetative propagation methods, there is still a question about “why graft chili plants.”

Chili plants are grafted to produce stronger, tastier, and wider varieties. Grafting chili plants is a fascinating thing to do with many chili pepper varieties. Grafted chili plants will bear fruits much earlier and for much longer than standard ones; therefore, planters can enjoy greater yield.

How to graft chili plants

Grafting chili plants makes it possible to have several varieties or various plants growing in a single chili plant. According to Fatalii.net, this method has “no time-consuming hybridizations or breeding, just graft the plants together and wait for the wounds to heal.” Then, the grafted branches will begin growing and producing a variety of fruits in the same plant.

  • Before anything else, be sure to wash your hands and the razorblade thoroughly using a bar of antibacterial soap. Rinse them well and dry them out with clean paper sheets. Then check out the chili plants with stems with the same size right above the first set of “true leaves,” as the graft will only take with plants of identical diameter stems.
  • Cut the rooted plant that receives the scion, known as understock, at a 30-degree angle. It should be approximately half an inch above the first pair of true leaves. Next, cut the scion (a young shoot or twig of a plant for grafting) at the same place.
  • Cut a 2-millimeter latex tube piece, roughly 1 1/2 inches long. Ensure that the tube ends on the same 30-degree angles as the chili plants. After that, slip the cut end of the scion into the tube — matching the cut angles, then push the scion until it is approximately halfway into the tube.
  • Slide the tube with the scion over the understock stem and rotate the tube to guarantee that the two (2) cut ends match up precisely. Then, push the tube down until the scion and understock ends touch against each other — creating a perfect match. Finally, position the grafted plants in a protected spot out of bright sunlight.
  • It will take a couple of weeks to notice if the grafting is a success. They may still be wilted for the first two (2) or three (3) days, yet will then straighten up as the graft takes hold. Make sure the plants are well-watered during this time.

On occasions, it will take more time to succeed, and sporadically, it won’t succeed at all. Hence, try to create several grafts at once as it’s pretty easy to do.

benefits of chili grafting

Chili grafting can offer several benefits to planters, including bearing more fruits and earlier fruiting and more prolonged fruiting. A greater yield or enhanced production is genuinely satisfying. Grafted chili plants will also have better resistance to soil-borne pests and diseases, and nutritional disorders.

If situated in a warm, sunny, and protected area, grafted chili plants are more effective for outdoor growing. They can also produce a robust growing variety of great chilies for daily use and highly multipurpose. Planters can surely acquire more excellent value from chili grafting. 

If grown in greenhouses, grafted chili plants only entail less heat. Thus, saving both energy and money. Furthermore, planters can take advantage of the longer harvests compared to regular chili plants.

Some chili varieties can also be ideally grown even in tiny containers, suitable for small space gardening. With grafting, chili plants will have robust root systems and stems — making it possible to attain a quicker growth rate and ripening pace. It is the principal benefit of grafting plants.

Should I transfer grafted chili plants?

As chili plants grow, you must transfer them into larger pots to ensure that their roots have plentiful space to develop. When transplanting them outside or into their new pots, make sure that the point you did the graft is above the compost; otherwise, the variety will root itself. It will mar the benefit of growing on a forceful rootstock.

When the plant reaches approximately 40 centimeters or 0.4 meters in height, transfer it to its final growing location — a greenhouse or a pleasant sunny position in a spot right in the garden or in a pot on the patio. Keep in mind to only place the chili plant outdoors if there’s no more threat of frost.
