To make fir tree seedlings from fir tree branches, you can take cuttings from the branches in the spring or early summer. Choose healthy, young branches and cut them into 6-8 inch sections. Remove the lower needles and dip the cut end in rooting hormone. Plant the cuttings in a well-draining soil mix and keep them moist and in a humid environment. With proper care and attention, the cuttings should develop roots and grow into fir tree seedlings. **

No, Douglas fir trees are not toxic to humans or animals. In fact, the wood of the Douglas fir tree is commonly used for construction, furniture, and other woodworking projects. However, like any tree, it is important to handle Douglas fir with care and take necessary safety precautions when working with the wood. **

Lower classifications of fir trees include the subgenus Abies, which consists of about 50 species of true firs. These firs are further divided into different sections based on their characteristics, such as the balsam firs (section Balsamea) and the silver firs (section Amabilis). Each section contains several species of fir trees that share similar traits and habitats. Overall, the lower classifications of fir trees help to organize and categorize the diverse species within the genus Abies. **

Horses should not eat fir trees as they are toxic to them. Fir trees contain toxins that can be harmful to horses if ingested, potentially causing digestive issues, colic, and other health problems. It is important to ensure that horses do not have access to fir trees or any other toxic plants in their environment to keep them safe and healthy. **

Cattle should not eat fir trees as they are toxic to them.

Douglas fir is moderately weather-resistant, making it suitable for outdoor applications such as decking, fencing, and siding. It is more resistant to decay and rot compared to other softwoods, but it is still recommended to treat or seal Douglas fir to enhance its durability and longevity when exposed to harsh weather conditions. Proper maintenance, such as regular staining or painting, can help improve its weather resistance and protect it from moisture damage. **
