Gravel: Filling the hole with gravel will help to support the fence post. This method is stronger than using dirt, but not as strong as using cement. Sand: Filling the hole with sand will help to support the fence post. Like gravel, this method is stronger than using dirt, but not as strong as using cement.
Yes, it can be installed into the soil without using cement if you want it to lean over after a very short time. However, if you want the fence and the post to do it's job and to stay upright in a gale, then make the hole and use bagged post mix.
You can use a post hole digger or post driver to help create the hole. Add about 10-15 cm of gravel to the base of the hole to increase the drainage ability. Position the post in the hole and drop two stakes into the soil next to the pole. Nail or screw two pieces of wood between the stakes and the pole.
Put some gravel into the bottom of the hole and tamp it down well with the post. The place the post and add a bit more gravel around. That will keep the open grain end from being in direct contact with soil and reduce moisture wicking/trapping.
Whether you're building a fence, setting a mailbox or even a basketball goal, the best way to ensure your posts will stay sturdy and true for years is to set them in concrete.

Setting fence posts in gravel
Gravel is less messy than concrete, but it can be less durable. Gravel is best for fencing in heavier (more clayey) soils, and won't work well if you have loose, sandy soil. Gravel also allows water drainage around the fence posts, making the posts less susceptible to frost heaves.
If properly treated and installed, pine fence posts can last for 20–35 years; untreated pine posts might only last 3–7 years. chemical in the posts. When large numbers of fence posts need to be installed it is probably most practical to pound them into the ground with a hydraulic post driver, small end first.
Place a wood block over a spike and drive it into the ground with a hammer, mallet or sledge hammer. The wood helps to protect the spike from damage. Make sure the wings of the spike are flush with the ground. Starting with one corner, slide the post through the eyelets of a panel and into the stake.
The general rule of thumb when setting a post is that the depth of the post's hole needs to be one-third to one-half of the actual above-ground height of the post. So, a six-foot-high finished post ideally needs to be buried three feet into the ground.
Fast-setting concrete is ideal for setting posts because there's no mixing—you simply pour the dry concrete from the bag right into the hole, then add water.
Drop two stakes into the soil next to the post. Nail or screw two pieces of wood between the stakes and the post. This is just temporary to keep the post in place until the concrete has set. Repeat this process for all posts that require a concrete base.
Using concrete when setting your fence posts will increase the sturdiness of the entire fence. Fences set in concrete are proven to move less in unstable soil and high winds than other mounting systems or methods.
Fill your hole with soil or with crushed stone or gravel. With crushed stone, you have better drainage than you would have with soil. You may also improve the overall stability of the post if the gravel is put into dense soil.
Cedar and redwood are naturally resistant to decay and insect damage, making them excellent choices for ground applications.
Treat the Post With Preservatives
Prior to installation, soak the bottom of the posts in a wood preservative containing copper napthanate, such as Cuprinol. Note: Available at some paint stores and home centers, this wood treatment is specifically designed for in-ground applications.
The one-third rule – if there is one rule above all the others to remember it is this one. The one-third rule is a classing rule of fencing. Always aim to bury at least one third of your fence post underground. So, for an 8' high fence post, ensure a minimum of 2' is underground.
Fill with Gravel or Concrete
Gravel helps keep moisture from the fence posts, slowing the rot. Concrete can more sturdily set the posts, but the moisture in the concrete may collect and absorb at the bottom of the post, accelerating the very process you're trying to mitigate.
The length of time people engage with a post before it becomes lost in the digital abyss is its "lifespan" or "lifetime." Understanding the lifespan of your posted content can help you decide where to focus your efforts.
Backfilling with Gravel and Soil. Fill the first few inches of the hole with gravel. This aids in drainage, keeping wood posts dry and preventing rot. After the gravel, backfill the hole with the dug-up soil, tamping down every few inches to eliminate air pockets and ensure soil compaction.
There are, however, more advantages (and less negative aspects) to having a gravel driveway with pavers installed. Not only will they last much longer than a concrete driveway when properly maintained, but they come with a whole host of other benefits for you, your family, and the environment.
