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.

If your Pachycereus marginatus doesn't receive enough light, its stems may grow leggy and become paler, so make your Mexican fencepost cactus happy and give it plenty of light.

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. Instead, make or buy a well-draining potting mix, or ideally, use our Go to Soil cactus mix blend 1 gal 4 qt cacti succulent dirt compost growing media that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your cactus thrive.

Horrible quality
Size: 6.5x10ft, Color: Red
Horrible quality. The crank didn't work. The umbrella just flopped open. Once it did I cranked it, but it was cranking in wrong direction. Umbrella sat totally lopsided. The overall quality of this umbrella including the canopy is junk. Looks cheap. Returning!!

Peacock Blue
Size: 6.5x10ft, Color: Lake Blue
Not out yet because of weather, but it looks good, unusual point that some of the spokes according to the directions need to be put on yourself, but at least this way they not bent in box. Note when I bought it - it used the color Lake Blue but the picture was a Peacock Blue - I took the chance and it is a Peacock Blue- I would not call it Lake at all or sky or any of those colors. It worked out for me as it matches perfectly with my Peacock Blue cushions and other umbrellas, It defintiely seems like it is sturdy and the size looks as it should, it has a nice weight as i did open it in house to take a look, the material has a slight sheen which makes it appear a little different than my others, but not something most people would notice.

Attractive and seems like it will hold up
Size: 6.5x10ft, Color: Blue-Green Stripe
Seems sturdy enough. Tilt button is difficult to retract to straight, but maybe just my finger strength, or it will loosen up with time. The color of one of the stripes is off from the photo. I was hoping it was turquoise as shown in picture, but is actually a much deeper blue. Doesn't coordinate with my other patio colors like I hoped it would, but it will do.
