If you don't have a big garden, we don't recommend you grow pecan trees because they can reach up to 150 feet in height, and there are no dwarf varieties. Cross pollination (pollination between two or more varieties) will enhance production slightly but is not absolutely necessary in most cases. Juglandaceae are represented worldwide by between seven and 10 extant genera and more than 60 species. Each colored line represents the yearly production in pounds of nuts from an individual tree beginning the year planted. The following are ways to potentially improve nut production: If possible, provide one to two inches of irrigation water per week during the growing season. Note the up and down production from trees in an alternate bearing cycle. To assess the replacement value of one or more pecan trees fairly, the following factors must be considered: • Age of tree(s) Without fungicide applications, certain cultivars would experience yield losses ranging from 50 to 100 percent, depending on the year.
