How to Plant Guava Seeds

Soilless seed-starting mix
Press one guava seed into the center of the pot. Use your thumb to gently press the seed under the soilless mix, and cover it with 1/8 to 1/4 inch of the mixture.
Place guava seeds in a pot of boiling water, and boil for five minutes to break seed dormancy and speed germination.
An alternative to boiling the seeds is to soak the guava seeds in water for two weeks prior to planting. Seed treatments, called stratification, allow the seed coat to soften and germinate. Different seeds require different preplanting treatment.
Growing tropical guava in a greenhouse or on a protected porch from seed is a fun project to try. In tropical climates, guava trees grow up to 12 to 14 feet tall, but kept in a container, they stay small enough for a covered porch or small greenhouse. Commercial growers use grafted trees to get specific fruit characteristics, but in the home garden, growing guavas from seed is a simple and fun way to add to the garden landscape. Grow guava outdoors in U.S. Department of Agriculture plant hardiness zones 9a through 10b. In the chillier zone 8 areas of the region, keep your guava tree in a pot on a sunny, covered porch in winter.

Place the pot in a warm place with a temperature of 65 degrees Fahrenheit or above. Guava seeds germinate in two to eight weeks.

Guava seeds planted in containers stay small enough to keep on a porch. Seeds are boiled to break dormancy and speed germination then planted in a pot with soilless seed-starting mix. The pot should be sprayed with water to prevent disruption of seed then placed in a warm spot to grow.
