Fusiform rust is a disease involving swollen elongated galls, which are abnormal outgrowths on branches or trunks. An infected tree can become stunted in growth or even die. Whenever a gall occurs on the main trunk of a young tree, the tree should be cut down and removed. Galls on branche...
Pine tree needle diseases are caused by fungal pathogens. The infection results in the defoliation and discoloration of conifer needles. Both reduce the tree's overall health. Early identification and removal of infected areas is the best method of control. Highly susceptible conifer tree species in...
A matured Chihuahua pine can grow to heights between 60 and 140 feet and have branches that slope upwards, beginning at the upper 60% of the tree’s trunk. The Chihuahua pine exists alongside other pines but can also stand alone.This species is planted commercially in the East African ...
Resin bleeding coats the trunk and lower branches below the point of the infection. At this point, the breakage of these branches and even the stem can often occur due to loss of structural integrity or windstorms and the tree eventually dies [14,15]. Root infection promotes brown ...
Pine pollen has been studied for increased testosterone levels and a decreased risk of inflammation. See what the scientific evidence says.
Can a Japanese umbrella pine tree grow in a container? Though it's a slow-growing tree, growing this tree in a pot may still be a temporary situation. A Japanese umbrella pine's branches grow pendulous, its trunk grows broad, and it will probably become too unwieldy to leave in a conta...
The yield is up to 5.5 kilos per tree. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile. Resins are obtained by tapping the trunk, or by destructive distillation of the wood...
Southern pine beetles lay their eggs on stressed or diseased pine trees. When the larvae hatch, they tunnel under the bark in an “S” pattern. The tunnels destroy the cambium and cause masses of resin, called pitch tubes, on the trunk of the tree. The needles of infested pine trees tur...
