Robinia Fence Posts: Durable Wood for Permanent Fences, No Chemicals
Robinia wood stands up to weather and soil moisture for many years without impregnation. Here you will find whole and split posts for your paddock.
Robinia Fence Posts: Naturally Long-Lasting in the Ground
Robinia fence posts are popular with horse owners and farmers because the wood is naturally very resistant. It copes with wet, frost and contact with the soil far better than most European woods. You do not need any chemical impregnation. That makes robinia, also known as black locust, an attractive option for anyone who wants to use untreated timber in their field.
Whole and Split Posts
A whole robinia post with a round, naturally grown cross-section is suited to corners, ends and gate posts, where the tensioned conductor pulls hardest. The split robinia post is lighter, easy to transport and works well as a line post along a straight run. Because robinia grows naturally, every post is shaped a little differently. That gives the fence a rural character that suits horse paddocks and orchard meadows.
Tips for Putting Them Up
Robinia is very hard. Pointed posts are best driven in with a heavy mallet or a rammer, and in firm ground you make a pilot hole first. When fixing insulators, pre-drill if needed so the wood does not split. Make sure the polywire, polyrope or polytape never touches the wood. For an electric fence, use screw-in insulators or nail-on insulators, with matching corner insulators at the corners.
Frequently asked questions
Why does robinia not need impregnating?
Robinia wood naturally contains substances that protect it against fungi and rot. That is why it lasts a long time even in the ground. Additional treatment is not needed for fence posts.
Is robinia safe for horses?
As an installed fence post, robinia is common. However, the bark, leaves and seeds of robinia are considered toxic to horses. Keep the posts behind a live conductor so the animals do not chew them, and clear away any loose bark from the field.
Do robinia posts turn grey over time?
Yes, untreated robinia develops a silvery grey patina from sun and rain. This is purely a colour change on the surface and does not affect the strength.
Robinia for Paddocks and Fields
Robinia wood has made a name for itself in fencing because it lasts a very long time in the ground without any chemical wood protection. For you, that means you set the posts once and can forget about them for many years. Whole posts take the strain at corners, ends and gates, while split posts are lighter and work as line posts along straight runs. With screw-in or nail-on insulators, your wooden fence becomes a safe electric fence for horses, cattle, sheep or goats. The naturally grown cross-section means your fence does not look mass-produced but blends calmly into the landscape. Over time the wood takes on a silvery grey patina that suits fields and farmyards. Choose whole posts for corners and gates; split ones are enough along the line. Split posts are also easier to carry across the field.
