Do Grow Bags Topple Over From Wind?

I can't dig at all where the plants will be. I think 7-10 gallon grow bags would be more practical thank buckets. Summer is not long and not too tropical around here.

So is 7-10 g large enough and do these things stand up by themselves or have to be propped up some how?

Depends on your wind, but I always recommend supports. I would DIY tomato cages around them (anchored to ground)

Like he said it really depends on how strong the wind,But when and doubt be ready for weather changes and have a plan,Because this year the weathers really weird...

They are definitely more stable than hard sided containers.

its really good if you can dig a hole to put them in. i just have 1 plant in a 15 gallon pot in a hole thats about a foot deep. the pot sticks out about 6 inches. the plant will break and fall over before the pot will im sure.

wow sorry, i just now read your first sentence derrrrrrrrrrr

I have wind (lol)...When I used 10 gallon bags they never fell over.....Don't try and move them around too much after they have been out in the sun, they love to shred up...The white ones are stronger than the black ones I used.....
