Removing fence posts that are set in concrete is something you can't do by hand. You will need an excavator, a strong post-puller, or a jackhammer. If you plan on recycling the concrete base, you may be able to cut the post out with a jackhammer and then set the new post in the existing base. However, it's usually better to remove both the fence post and concrete together. Due to the weight of concrete, you will need a hydraulic removal tool.

The recommended height for a garden fence depends on its primary purpose. For pest control, the necessary height varies by animal. To keep out small pests like rabbits, a fence should be at least two to three feet tall. If you live in an area with deer, you will need a much taller fence, at least five feet high, to prevent them from jumping over. If the main goal is privacy, the fence should be at least seven feet tall. For purely decorative fences, the height is a matter of personal preference.

Yes, you can use a floor jack to remove fence posts. Attach a stem to the base of the fence post so you can position the floor jack underneath. The stem can be a scrap piece of wood attached with nails or a sturdy nail itself. Put the jack beneath the stem and push the lever to lift up on the fence post and remove it from the ground.

If you come face-to-face with a wolf in your yard, chances are it will be afraid of you as a human. Make eye contact and get big—waving your arms to increase your size. Use noisemakers or air horns if you have them, or throw a few rocks around to discourage them from approaching you. If all else fails and the wolf does not retreat, back away slowly while maintaining eye contact and find safe ground, whether indoors or up a tree.
