Upside down tomato garden, also known as a topsy turvy tomato planter
This is the ultimate upside down tomato planter, which you don’t even need to buy, it tells you exactly how to make your own from a disused plastic bucket.
Couple of things I would note, don’t miss the use a metal handle tip and I would use a drill to take out the hole rather than using a Stanley knife as demonstrated, you could just loose a couple of fingers doing it that way. Other than that, this video says it all when it comes to making your own topsy turvy tomato planter.
