Sure, you can bury them deep. They just need a couple of leaves to gather sunlight.

You can, that's fine. But, they aren't as prone to growing roots out their main stem as tomatoes are.

It depends.

If the main stem/trunk has already begun to lignify (turn woody),
then the chance of rooting is less likely....and the chance of rotting more likely.

Planting the stem deeper is a technique generally used with young, etoliated seedlings,
while the stem is still tender and the growth dynamic.

Thanks guys.

Yeah. They're still pretty young. Just a little top-heavy and bending. I just want to straighten out the growth.

They will grow roots, even from woody growth. Not quite as much as tomatoes, but they will do it. If you grow in a water retentive soil, you'll often see them grow roots above the soil line in an attempt to get air. I've seen it in peat based soils before I started using 5:1:1. But others are correct in that it's best when the stem is still green. Should be no issue.

woohooman, if you plants are wanting to bend over, just make sure there isn't some other problem causing that. How tall are your plants now?

Bruce:

Well, now they're only a couple inches high after planting them a couple inches below soil level---LOL. But, they were about 4-5 inches high. It was definitely caused by stretching due to them wanting sunlight while I was away for a couple weeks.

Btw, a little experimenting I can do with my guajillos. I have 2 in my oak barrels that are organic based and 1 in a bucket with the 5-1-1(inorganic). I'll let you guys/girls know how it turns out.
