Partially Burying a Grow Bag?

[Greatgardens]

I use conventional metal tomato cages with my grow bags, and by doing that, I lose the use of a good part of the cage. One thing I could do is to cut up a cage and create some "extenders" to make up the amount lost (or even more). I don't know how sturdy the extended part of the cage would be. Burpee sells extenders for some of their cages, so presumably those extenders work OK. (Out-of-stock at this time, BTW).

Or, I could partially bury the grow bag. My grow bags are about 16" tall. I probably would not bury more than half the bag. That would seem to have some advantages and disadvantages. I might help keep the roots cooler. Every inch buried is an inch of useful cage gained. OTOH, drainage might be adversely affected and the bags may rot sooner. But normal watering requirements for the bag might be lessened a bit. We don't have nematodes in our area, so that is not an issue.

Maybe both are worth a try? What do you think?
