I beleive it is so the pots don't blow over? Dig a hole and put the pot in it. For people up North that have to take theirs in it is easier for them to dig up. That's my take on it.

In addition to what was stated above,I like to add, that there is less dehydration to the soil in the pot,when
it is sunk into the ground.

Do you have a hard time getting them up and out of the ground at the end of the season?

Do you put something in the hole to keep the hole from filling up with sand/dirt/mulch/debris and to keep someone from breaking their neck tripping in the hole?

I use pots for a few reasons. Mainly because I have noticed that my plumies stay happy.

I use the cactus mix you buy at the mega-mart or the big box stores. I plant the plumie just like any other plant. I dig a hole just a bit larger than the pot (like stuartwanda said, it helps them to stay upright) and secondly it seems that moisture stays where it is supposed to, near the roots. Because soil is like a sponge, nearby soil will soak up the moisture, the pot is like a barrier. Also, when you fertilize, the food stays where it is supposed to be.

When I lived in Orlando I would take the plumies in for the winter. The pot sinking made it easier to handle them and store in the garage for winter. I would back fill with mulch. When it came planting time again. I would trim the roots around the base of the pot and then sunk

Cliff,

Thanks for the info! It seems that I once saw a bunch of good photos that you posted of your sunk plumeria along a fence in your back yard. Was that you? Was that your house in Orlando? I looked for the post with the photos of the sunk pots but couldn't find it.

Hi Carol, I can't recall. i also did the pot sinking thing in Hollywood too. I do it here as well. It could have been that pic. I will have to look for it.
