You could look into Flickr.com or photobucket.com might let you post pictures.

Algae could well be a good food source for your soil and therefore your plants. Sounds cool.

I would be careful with the boron, it is typically added at a rate of one pound per acre and only when needed. If you use to much it becomes toxic.

Thank you for the advice,but I only use it every 5 years.I don't garden in dirt,but composted horse manure.The nutrients wash out in that time.

Thanks to tclynx.

Jackman, I'm not sure by reading your post - was this the first year you tried them in tires, or have you tried them in tires before, but this was the first year you added the algae sand?

The reason I ask - sweet potatoes like to be warm. I am reminded of this every year when I dig them up. The plants that are along the sides of the beds produce a lot more than the ones in the middle. I use pavers for the beds and presumably these pick up more heat. It's actually almost cute because the plants will snuggle their tubers up right against the buried part of the pavers. When I dig them, all the best tubers are right along the edges.

Given sweet potatoes' love for heat, the black tire idea sounds like it would make a lot of sense.

Diggity,I grew them using the algae sand for the first time.I will say the potatoes grow inside the tire.There could be a small root grow under the side of the tires,but they don't produce anything.I had read that algae is a good fertilizer. So I said what the heck,why not.When I saw how good they did I did a Google and found algae is loaded with Phosphorus.That is all I need to know.I will use the algae sand on all my root vegetables.

I just dug up some of my sweet potatoes for the first time. They seem to be doing wonderfully. I'm in a hot climate where they are a perennial here. I'm very happy with what we dug up. Definitely be growing sweet potatoes regularly here.

This was my first year to grow sweet potatoes and they did OK.

We had one the other night and it was much better than those we get in the grocery...not stringy at all. Most were normal size but one was over 18" long, L-shaped...neighbor said "it hit a rock"...no rock...was in a raised bed I created this last fall. There was one huge one that will need to be peeled and cut up or it will never get done.

I will definitely be doing sweet potatoes next year and think I will use some trashcans we drilled holes in that are black and dark blue. I will try growing some algae to use on these and see if I get a larger crop.

Thanks for the suggestion.
