(I have dropped and knocked over several of them!!)
An easy and cheap solution; get some disposible aluminum pie pans (they sell them at the grocery store in packs of 3) that
are wide enough so when you put your pot in it, there is a few inches of space all around.
Now, fill it with pebbles (gravel) as much as it will hold.
This not only adds a nice weight to the pot, it also prevents the pot from tipping over.
You can buy bags of pebbles at Lowes, Home Depot, or any garden store and they come in 10 to 50 pound bags, and cheap!!
I tipped over what I hope to be my last FT today. I was lucky it only fell over, didnt loose much dirt, and no apparent damage
to the plant (it was one of my Jaws!!)
This is particularly useful if you have your plants on a unstable wire shelf, like one of the mini greenhouses
Oh. and HAPPY 4th OF JULY EVERYONE !!!
