Having your very own guava tree is great. The fruits have a distinct and unmistakably tropical flavor that can brighten up any kitchen. But how do you start growing a guava tree? Keep reading to learn more about guava cutting propagation and growing guava trees from cuttings.
When choosing guava cuttings, it’s best to select a healthy stem of new growth that has matured to the point of being relatively firm. Cut off the terminal 6 or 8 inches (15-20 cm.) of the stem. Ideally, it should have 2 to 3 nodes worth of leaves on it.
Immediately sink your cutting, cut end down, in a pot of rich, moist growing medium. For better chances at rooting, treat the tip with a rooting hormone before placing it in the growing medium.
Keep the cutting warm, ideally at 75 to 85 F. (24-29 C.), by heating the growing bed from beneath. Keep the cutting moist by frequently misting it.
After 6 to 8 weeks, the cutting should have started to develop roots. It will probably take an additional 4 to 6 months of growth before the new plant is strong enough to be transplanted out.
Root cutting propagation is another popular method of producing new guava trees. The roots of guava trees that grow near the surface are very prone to putting up new shoots.
Dig up and cut off a 2- to 3-inch (5-7 cm.) tip from one of these roots and cover it with a fine layer of rich, very moist growing medium.
After several weeks, new shoots should emerge from the soil. Each new shoot can be separated and grown into its own guava tree.
This method should only be used if you know the parent tree was grown from a cutting and not grafted onto a different rootstock. Otherwise, you might get something very different from a guava tree.

Typically growing to only 10 feet tall, the pineapple guava (Feijoa sellowiana or Acca sellowiana) isn’t a large plant, which makes it ideal for those who want to grow fruit but don’t have a lot of orchard space. Depending on how it’s pruned, it can be grown as a small tree or a large shrub. Pineapple guavas do best in areas with cooler winters within U.S. Department of Agriculture plant hardiness zones 8 to 11. The tree propagates readily by cuttings, and, once rooted, requires little maintenance.
softwood cuttings from a healthy guava tree. The cuttings should be flexible and shouldn't snap when bent. Remove all but the top two leaves. Dip the bottom of the cuttings in rooting hormone and plant them in moist potting mix.
Similarly, how deep are guava tree roots? Guava trees can take root successfully in many different kinds of soil. According to the University of Florida, guava trees bred from cuttings, a common cultivation method, take root no deeper than 18 inches from the surface of the ground. Secondary shoots called root suckers often grow from the roots near the trunk.
Beside this, how do you grow a guava tree from a branch?
Branch Cutting and Rooting You can cut a healthy branch from a guava tree and encourage it to grow its own new root system. Cut a branch that is about 1/4 to 1/2 inch in diameter and about 12 inches long. Soak the cut end of the branch in water with a rooting hormone additive and place it in a warm place.
How long does it take to grow guava from seed?
Guava seeds will germinate as soon as two weeks after planting, but they may take as long as eight weeks. The trees can also be grown from root cuttings. Seedlings are fast growing, and they can be set out in the field after one or two years.
Root cutting takes a piece of a healthy guava's root system and uses it to propagate a new tree. This procedure can be risky to the healthy tree if you hit a key taproot, so stay away from the largest roots on the tree. Cut a piece approximately 2 to 6 inches long from one of the ancillary roots. Cut six pieces to increase your chances of success. Tie the root cuttings together loosely and store them for three weeks in a warm place, covered in sawdust. Plant the cuttings in soil about two to three inches apart and 2 to 3 inches below the surface.
Cuttings generally produce sturdier trees and superior fruit to those started from seeds, but they are difficult to root. Take cuttings of mature wood and root them in sand. Taken in winter while the tree is dormant, the cuttings should be 6 to 12 inches long. Cut just below a node to encourage strong roots. Use a pot deep enough to hold the cutting with one node exposed above the soil and 2 inches of soil below the bottom of the cutting. Cuttings root best in warm soil and benefit from a heat mat placed under the pot.
