The Giant huntsman spider is huge, but not deadly to humans. Biggest in the world, the Giant Huntsman Spider was just recently discovered in 2001 in a Cave in Laos.
Because of reduced competition from other trees, it tends to thrive in barren soil containing too much sand, gravel, or clay. Growth and development of young trees is rapid, and their longevity can extend to 50-100 years. Siberian Elm is resistant to Dutch Elm disease, which is often fatal to other elms. It is prone to storm damage from wind, snow, and ice (especially the latter), causing breakage of branches and twigs that can litter the ground underneath the tree.
A healthy 3- to 4-foot-tall American elm sapling bought from a nursery typically grows 25 to 30 feet high in 8 to 10 years. In about 40 years, it may grow up to 100 feet tall with a 60- to 100-foot-wide canopy and roots spreading the same distance.ative to Japan, Korea and China, the Chinese elm (Ulmus parvifolia), also called the lacebark elm, can grow more than 3 feet each year, topping out at 60 to 80 feet tall. It is hardy in USDA zones 5 through 9. It resists, but is not immune to, Dutch elm disease.
