When and How to Water Your Mexican Fence Post Cactus 

Desert plants, such as cacti, are adapted to grow with minimal water. By storing it in their foliage and trunks, these plants are amazing at conserving water. Therefore, it's important to keep the moisture in the soil to a minimum.  This Pachycereus marginatus Mexican cactus is like a camel; they drink up a lot of water quickly and then can last a long time before needing water again. 

Usually, watering once every two or three weeks is ample during the summer. In the winter, if it doesn't rain, you still should only water your cacti less than once a month.

If the plant doesn't receive enough moisture for an extended period of time, discoloration, pale stems, and browning can occur, leading to stunted growth. In contrast, overwatering can cause root rot and fungal infections.

Light Requirements - Where to Place Your Mexican Fence Post Cactus

If indoors, place your Mexican fence post cactus directly in front of a west- or south-facing window. Providing enough light for these desert cacti is one of the most important aspects of their care.

If you're growing them outdoors, make sure to find a location where they can receive at least 6–8 hours of direct sunlight each day.

Optimal Soil & Fertilizer Needs 

The Mexican fence post favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and, most likely, root rot.

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.
