Quick Answer
Dogbane cordage is strong enough for some survival uses, but its tensile strength is lower than other commonly used cordage materials like nettle or milkweed.
Understanding Dogbane Cordage
Dogbane (Apocynum cannabinum) is a perennial plant native to North America, known for its strong, fibrous stems that can be harvested for cordage. To create cordage from dogbane, start by cutting the stems to a suitable length, typically 3-6 feet. Remove any leaves and bark, then split the stem lengthwise and scrape out the pith to reveal the long, thin fibers.
Preparing and Testing Dogbane Cordage
To prepare the fibers for use, twist them together in a clockwise direction to create a single strand. Test the cordage by pulling it to its breaking point, which can be achieved by using a tensiometer or simply by hand. The tensile strength of dogbane cordage is typically around 300-400 pounds per square inch (psi), which is lower than nettle (500-600 psi) or milkweed (400-500 psi) but still suitable for some survival applications, such as creating a makeshift tow line or securing a shelter.
Using Dogbane Cordage in Survival Situations
In survival situations, dogbane cordage can be used for a variety of tasks, including creating a makeshift fishing line, securing a water filter, or creating a tarp or shelter. When using dogbane cordage, it’s essential to work with it when it’s still moist and pliable, as this will make it easier to twist and shape into the desired form. Additionally, dogbane cordage can be used in combination with other cordage materials to create a stronger, more durable rope.
