Container gardening, if the hour is late and you are fit to be tied for what to do, might be the best, cheapest, and most certainly quickest answer. DH and I moved into this house three years ago, and there really is no place suitable for a garden, except right up next to the house on the south and west sides, where the prior owners HAD rock, then barkmulched on top of it to cover the rock. Now, it's an ugly combination of rocks and bark, and since we both work full time and have three teenagers, time constraints didn't even allow for the "dig up and make it a real garden" option; besides, there are a few nice low shrubs that we didn't want to tear out. So, I did a little research and found the Earth Box. Did a little more research, and didn't begin to want to deal with their customer service, so continued to research. Found Garden Patch Grow Boxes, spoke with reps at customer service and felt pretty good about the company. Bought thirteen of them, and then found an Earth Box at a garage sale--great, this way I could compare. For the record, there is no comparison: the elasticized cover on the Earth Box (through which a gardener is supposed to make "X" hatches and plant starts), coupled with the butt-ugly black pipe sticking out, made the Grow Box a KO winner, especially when calculated in the GB came with the first year's supply of fertilizer. I have since discovered that their plastic covers will break down during the second year, so will be replacing all covers with some 4-mil plastic that I picked up in the Walmart hardware department, and using my own fertilizer, ala EB's original instructions, to make a "hybrid" growing box. Heat? Dry? Not a problem--the GB has a 4 1/2 gallon reservoir, and even on very hot days, if I water in the a.m. and check back in the p.m., they're never dry (and must NEVER be allowed to go dry). Weeds are not a problem, either; the bonus (that I didn't realize would be a bonus) is that we have terrible bindweed in our yard (okay, so that's not the bonus--wait for it!), and I didn't end up planting my garden into the ground right where the bindweed seems to be the worst. I never thought I would swear by container gardening, but I have grown carrots (in the same box with the tomatoes--who needs a separate stinking box!?!), peppers, radishes, eggplant, tomatoes, herbs, lettuce, cucumbers, squash, watermelon, cantelope, and flowers in my boxes. HUGE BONUS for container gardening: when we get our first hard freeze, I can take those suckers in the garage, and we'll have fresh tomatoes from our own garden well into January. They may not be as flavorful as those sun-warmed and -ripened that we miss from last August, but they're better than those pink mushy things loosely marketed as "tomatoes" at the local grocer, and not just cuz they're free! Good luck with your garden, and let us know what you end up doing!!!

I got my rock phosphate through Fedco Seeds, you might want to try them. Bountiful Gardens has good advice on cover crops, check them out.

I know this is an old thread but I wanted to update what I did over time to get "rid" of the lava rock problem that we had. This last week, I finally scraped alot of the remaining rock out of the large bed and spaded topsoil, compost and some organic fertilizer into the soil. However quite a bit of the lava rock remained and I spaded that in along with the amendments. I simply could not get all the rocks out with a flat type of coal shovel. I double dug the areas adding amendments each time along with organic fertilzer, soy pellets, etc. (Not alot of fertilizer but a sprinkling to get things cooking along with the compost in there.) Of course this was heavy, sweaty work but it is finally finished off. I wish I had been able to get almost all of the lava rock out of there but too much of it had already been mixed in with soil over the years and I simply couldn't get it all out without removing ALOT of the soil along with it. But I was able to spade the vast majority of it back into the amended soil before adding a final layer of topsoil, compost, soy pellets and wood mulch. (In the end I probably added back 4 inches of amendments to make up for the removed lava rock and put another 3 inches of wood mulch on top of all of that.) So now most of the remaining lava rock has finally been worked into the soil where it can hopefully decompose more quickly and become part of the soil. I NEVER recommend lava rock or landscape fabric to anyone but if you move into a house that has them you can probably get away with leaving some to dig into the soil. I say this because after all the amendments and digging in of the remaining lava rock (which was still a fair amount of lava rock) the final "soil" drains well. (But it took ALOT of work that wouldn't have been necessary if I had never had the lava rock in the first place.) The plantings are doing very well but I'll know more this summer when the wife plants flowers into this newly amended soil with some lava rock spaded in. Time will tell. In the end though, I WILL NEVER use lava rock or weed barrier fabric on my garden ever again. These were the two biggest mistakes I have ever made in all my years of gardening. Just my personal opinion. (The reason I got rid of mine and/or incorporated the remaining lava rock into the soil was it had become unsightly over time and some parts stayed too damp and a small bit of moss was growing on some of them. This situation had to be corrected because it was really bugging me. LOL!) Finally, I was surprised to find quite a few earthworms in this old "lava rock" soil when spading in all the new stuff. That did really surprise me, I didn't expect to see earthworms in this old stuff. Now the earthworms have a good soil to live in!! (I hope!!)

This forum is primarily about sowing seeds in the winter and spring using Trudi's technique with containers, etc. I'm thinking you might want to ask this on the veggie or tomato forum?
