A honey locust tree is a deciduous shade tree that is popular in urban areas because it is tolerant to stress and pollution. The tree grows in both thorny and thornless varieties with tiny frond-like leaves that grow on a branching leaf stem, flowers in spring and fruit that grows in long, curling seed pods. Some individuals who plant honey locusts as an ornamental tree consider these seed pods to be "nuisance fruit." Honey locust pods can be prevented with the use of chemicals that prevent the fruit from forming.
Wait until just after the flowers have formed on a honey locust tree.
Pull on protective clothing while handling chemicals.
Mix the growth-regulating chemical with water according to the package directions.
Pour the chemical into a pressurized chemical spray bottle. Close the lid and prime the bottle by working the pump until pressure is built up inside your spray bottle.
Spray the chemical onto your honey locust tree, taking care that it does not drift onto other plants or contaminate your plant irrigation system.
Both honey locust and black locust trees respond well when young to an autumn application of compost, aged manure paired with bone meal, or to commercially-prepared tree fertilizer, usually 10-10-10. All locust trees are extremely tolerant of poor soil conditions.
Known for its rot and warping resistance, black locust wood is a good choice for fence posts because you want a post that lasts for years and is not easily damaged. Working with black locust might be tougher than with most fence post materials, however, because the wood itself is so durable. Nailing boards and drilling will take more effort than with other fencing.
