About Guava Reproduction
Guava trees are most often propagated by seed or cuttings. Either method is fairly easy so choose whichever works best for you.
Guava Tree Propagation with Seeds
Planting seeds is a relatively easy way to propagate a new guava tree, but keep in mind that the trees probably won’t be true to the parent tree. However, it’s still worth a try.
When it comes to propagating guava trees with seeds, the best plan is to plant fresh seeds from a ripe, juicy fruit. (Some people prefer to plant the fresh seeds directly in the garden.) If you don’t have access to a guava tree, you can purchase a guava at a grocery store. Remove the seeds from the pulp and wash them thoroughly.
If you need to save the seeds for planting later, dry them thoroughly, place them in an airtight glass container, and store them in a dark, cool place.
At planting time, scrape the seeds with a file or the tip of a knife to break through the hard outer coating. If the seeds aren’t fresh, soak them for two weeks or boil them for 5 minutes before planting. Plant the seeds in a tray or pot filled with fresh potting mix. Cover the pot with plastic, then place it on a heat mat set at 75 to 85 F. (24-29 C.).
Water lightly as needed to keep the potting mix slightly moist. Guava seeds generally take two to eight weeks to germinate. Transplant the seedlings to pots when they have two to four sets of leaves, then move them outdoors the following spring.
How to Propagate a Guava by Cuttings
Cut 4- to 6-inch (10-15 cm.) 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. A 1-gallon (4 L.) container will hold four cuttings.
Cover the container with clear plastic. If necessary, use sticks or plastic straws to hold the plastic above the leaves. Alternatively, cut a plastic soda bottle or milk jug in half and place it over the pot. Place the container in a sunny location where temperatures are consistently around 75 to 85 F. (24-29 C.) day and night. If necessary, use a heat mat to keep the potting mix warm.
Watch for new growth to appear in two to three weeks, which indicates the cuttings have rooted. Remove the plastic at this point. Water gently as needed to keep the potting soil slightly moist. Transplant the rooted cuttings into a larger container. Place them in a warm room or a sheltered outdoor location until the tree is mature enough to survive on its own.
Note: Young guava trees lack a tap root and may need to be staked or supported to keep them safely upright until they are well established.

How to Propagate Guava
Growing your own tropical garden is as easy as harvesting and planting the seeds of fruits from the local grocery store or farmers market. The common guava (Psidium guajava) is one of the few small trees that sets fruit within only two to three years after germination. Native to Mexico and Central America, the guava is hardy in Sunset's Climate Zones 23 to 25, 27, H1 and H2. It thrives as a potted plant in brightly lit sunrooms in other climates.
Planting & Growing A Pineapple Guava Tree From Cuttings
The easiest to root pineapple guava tree cutting is one taken from the bottom of the tree, according to horticulturist Michael Dirr. These cuttings rooted 87 percent of the time, while those from the middle and the top rooted 63 percent and 9 percent, respectively. Cuttings should be one-fifth inch in diameter, contain at least three nodes, or areas on the cutting where the leaves join it, and have two leaves at the tip. The ideal time to take the cutting is in November. The powder should be applied to the bottom 1 inch of the cutting after wounding it with a razor blade or scalpel. In hotter inland areas, plant the tree in a spot that receives sun in the morning and light shade in the afternoon. The pineapple guava is a drought-tolerant tree and requires no irrigation if it’s being grown as an ornamental.
Stage 2. Germinating
This growth stages of guava start to germinate. This means that the seeds will produce some roots and small green leafy leaves.
Germinating guava seeds will have high percentage of germination if you have a quality seeds. The quality seeds are the mature seeds which are capable of growing.
It should be harder enough which surely a sign of a good seeds. White or orangeless color would be best. You can buy some guava seeds near your location, like in the agriculture market or store.
They sell those seeds with coated color which help the seed to stay last long. But it’s rare to find this kind of seeds because usually people gets seeds directly from the fruit.
They buy fruit from the market and then get the seeds inside.You can also try to borrow or lend seeds from other farmers or gardeners in your location.
If you want to germinate seeds and grow it, the best way you should do is grow it first on the seed box. The seed box have many small container which you can put the seeds and grow.
Prepare your soil, make a hole around 1 inch deep and put one seed per hole. Cover it with soil and then water it. After 1-3 weeks the guava seeds will start germinating.
This takes few weeks in order to produce some roots and eventually you will see some small leaves.
You need to take care for it to grow it well. But honestly, its hard to germinate guava seeds.
If you want to grow guava we recommend buy guava seedlings from the market instead. It will surely grow and do your effort.
Coolidge – One the best varieties for Northwest gardeners, this early-ripening, self-fertile variety bears good crops of very large, dark green, tasty fruit.
Nikita – We found this attractive variety at the Nikita Botanic Garden in Yalta, Ukraine. Among the earliest to ripen, it is prized for its tasty fruit and its compact growth habit.
Apollo – Apollo has medium to large, oval fruit with smooth, thin, light-green skin and a blue-green surface bloom. Pulp well-developed, slightly gritty. Flavor very pleasant, quality excellent. Ripens mid to late-season. Tree upright and spreading, to 8 ft. tall, vigorous and productive. Self-fertile, and will pollinate our other varieties!
Mammoth – As its name implies, Mammoth Pineapple Guava is a very large fruit, in fact, it is the largest of all our varieties. Sweet and flavorful, Mammoth is also early ripening. Plant with another variety or seedling for cross-pollination.
Robert – A valuable, self-fertile, New Zealand variety, Robert is prized for its profuse flowers, large flavorful fruit, and compact growth habit.
And more to come in the future. At the time of this writing, we are growing Edenvale Improved Coolidge and Nemetz Pineapple Guava for cuttings to be used in future production.
