Spacing depends on the size of equipment to be used in the plantation. It is not a venture for absentee landowners unless someone is available to work the plantation on a routine basis. During the growing season, daily attention is required. A good example of regular work is insect pest control. An intensive insecticide spray program is an integral part of plantation work.
Insects are more susceptible to control measures at specific times during their life cycles.
To get the optimum benefit of spraying with minimum insect damage to the trees, monitor the life cycle. Many growers use pheromone or sex-lure traps to monitor peak insect activity. When peak activity occurs, growers must spray. Soil moisture is critical the first year that seedlings are in the ground. In South Central and West Texas, trickle irrigation systems are used on Afghan pine plantations.
