The Black Locust Tree and Why You Want Many

Black Locust can grow up to 170 ft tall#

Grows 3-4 ft. per year#

Native to North America#

Cold hardy in zones 3 to 8#

Firewood#

• BLT wood, on a pound for pound basis is roughly half that of Anthracite Coal
• Since its growth is fast, firewood can be plentiful

Timber#

• Rot resistant due to a naturally produced robinin in the wood
  • 100 year life span in full soil contact! (better than cedar performance)
  • Fence posts
  • Outdoor furniture
  • Outdoor decking
• Sustainable due to its fast growth and spread
  • Can be coppiced (cut to the ground)
  • Can be pollarded (cut above ground)
• Its dense wood makes durable tool handles, boxes (tool), and furniture
  • The wood is tougher than hickory, which is tougher than hard maple, which is tougher than oak.
  • A very low rate of expansion and contraction
  • Hardwood flooring
  • The highest tensile beam strength of any American tree
• The wood is beautiful

Legume#

• Nitrogen fixer
  • Fixes the same amount of nitrogen per acre as is needed for 200-bushel/acre corn
  • Black walnuts inter-planted with locust as “nurse” trees were shown to rapidly increase their growth [[Clark, Paul M., and Robert D. Williams. (1978) Black walnut growth increased when interplanted with nitrogen-fixing shrubs and trees. Proceedings of the Indiana Academy of Science, vol. 88, pp. 88-91.]]

Bees#

• The edible flower clusters are also a top food source for honey bees

Shade Provider#

• Its light, airy overstory provides dappled shade
  • Planted on the west side of a garden it provides relief during the hottest part of the day
  • (nitrogen provider)
  • Planted on the west side of a house, its quick growth soon shades that side from the sun

Wind-break#

• Fast growth plus it's feathery foliage reduces wind for animals, crops, and shelters

Fodder#

• Over 20% crude protein
• 4.1 kcal/g of energy
