I'm handicapped by severe arthritis due to lupus and sjogrens so am looking for an easier way to plant tomatoes this year. Saw the topsy turvy on TV but thought they just wanted TOO MUCH money for what they were offering so am very glad to see the milk jug ideas. I did have one thought on the topic but don't know how it would work since I haven't t tried it.
What about filling up the gallon jug with soil first, (but first put a few poke holes in the bottom for drainage) and then watering to settle the soil down. Fill with soil agin to bring it up to the neck of the jug and water again to settle the dirt down, and continue until it is at the neck of the milk jug. Then, plant your tomato seed, wait for it to sprout, or plant a small tomato seedling and get it settled in and then turn the jug upside down and hang.
Of course, then you would need a larger hole in what was once the bottom for watering. Maybe this would work and it would be a whole lot cheaper than two payments of $19.99 plus S & H. If anyone is good with yarn, you can buy cotton yarn at Walmart and you could braid a holder for the milk jug to it would hang evenly, kind of like the old macrame' from the 60's. :happy_flower
