How to grow guavas.
Guava can be grown from seed; seeds take 2 to 8 weeks to germinate. Seeds do not always grow true. Guavas can be grafted by patch budding, side-veneer grafting, and marcotting. Guavas can be grown from root cuttings; place 5 to 10-inch root cuttings in potting mix and cover with 2 to 4 inches of soil.
