Preparing Pilosocereus for Summer?

xica_da_silvaMay 11, 2012

Hi all,

Some of you may recall that I had planted a 2 ft. tall Pilosocereus cactus in my yard last fall (on the west side in full sun). So far, it has done great! He even grew a single beautiful creamy white bloom a month or two back, that I noticed early in the morning. I was hoping it would stick around but it was gone by the following day!

Anyhow, this may sound like a stupid question, but should I be concerned about the summer exposure to our extreme temps? I know in its natural habitat in the dry/hot Northeast of Brazil, it can at least handle temps in the 90-100s...but what about when we get to our averages of 105-110F on a regular basis? And I do have him surrounded by decorative rocks, so that probably makes it even hotter. He's seemed to have had no problems so far, but I'm wondering if I should rake some rocks away from his base to make it cooler, or even make some kind of shade? He's so pretty I want to make sure I keep him alive and healthy (I already know they're sensitive to frost, btw).

Any advice would be greatly appreciated!

Hiya Xica and all,

I've had one in the ground in my back garden in full nonstop sun for almost four years now and I've had zero problems with it summer or winter, including the record low temps of the 2010-2011 winter. I don't cover anything summer or winter and this plant has done just great. I wouldn't worry about it too much, but individual mileage may vary of course, LOL, so let us know how things go and what you do. I water mine once a week when it's HOT and maybe once a month when it's not. It's grown a lot since I got it.

I'm envious of the bloom on yours, by the way! Continued success with yours!

Take care,

Hi Grant!

Thanks! I was hoping you would see my question because I did remember you mentioning that you had one. I am really relieved that I won't need to create a shade structure for it, because I've already got my hands full with doing that for some other garden items!

I've been busy lately but am hoping to post a picture of it as soon as I get a chance. It's definitely one of my faves! Take care...and happy gardening!
