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.
Tips. 1  Trim dead or diseased branches in the fall only if they pose a safety hazard. Pruning in the early spring puts less stress on the tree. 2  Watch out for insect damage from the elm leaf beetle. The Siberian elm is one of the few elm trees resistant to Dutch elm disease, but insects and bacterial wetwood disease can still affect it.
