Hi Sarah, I'm Pam. :) I can see the advantages and disadvantages of your set up. I looked at the ingredients of the soil mix your using and it seems pretty dense to me. Quote: Contains a blend of sphagnum peat moss, compost and natural fertilizer... Sounds like a good, readily available base to start with. To me, here in the temperate rain forest, it would turn into a bog much of the year. Bog plants are nice. But... adding materials to give it more texture, so the roots have air seems the next step.I will link to the thread you want over in the container forum at the end of this post. It's a very long first post full of facts, so I suggest first scrolling through to get a feel for what's there and focusing on the relevant parts for you, right now. You may want to bookmark that one. Where I am, in a city too, I can get super large bags of pumice at an outlying farm supply store. Not sure the size of the bag, but I can't reach all the way around it and it stands up to my shoulders. One bag lasts me a couple of years. The tiny bags sold in most stores are way too expensive, so this might be something you could look around for, if you have transportation. I also use lots of 'bark mulch in my potting soil mixes. I have a gas station three blocks over that brings in medium sized fir mulch each spring/summer, so I walk my garden wagon over off and on and drag back another bag. It's funny seeing car passengers trying to figure out what that old lady is up to. When I bring a bag of manure home on the bus, in my granny cart, it seems better to wrap it in a plain black garbage bag. What they don't know, won't hurt them. LOL. My point being we each find sources that work for the individual. I like the idea of the boxes on the concrete, since it' will be easy to keep the children clean and not tracking stuff in, plus it's small enough you can keep track of things pretty easy and not get discouraged. I'm wondering how it is going to hold moisture in the heat, and how the heat will affect the center and the edges differently. A great garden experiment. I bet the heat loving herbs will thrive in just the right spot. All that extra heat from the concrete will be just heaven to them. My first idea for the plants like a tomato that wants deeper soil. What about adding some bottomless boxes. That could look really nice. Carefully arranged to look good from the window, but with the taller things not shading the other plants nearby. Yeah, this is where you move things around a few times.Any deeper container will work. I'm picturing the tomato roots going down through the container and then spreading out to where ever in the bigger 4X4 box it finds suits it needs. I wonder if somebody on http://pinterest.com/# has done something like this, it could look so interesting. You have a good base to build on. Two budget tips, since this garden thing doesn't get built in a season, would be 1. at the end of the season some places that only sell soil amendments part of the year, put it all on sale. That's a great time to stock up and have ready for next year. And 2. This is the time of year many counties run composting workshops, and also sell smaller plastic bins at a greatly reduced price. The one sold here is the Earth Machine. It's a nice way to start out. Doing a spring clean up around the area may give you some older fall leaves, then add the weeds and some kitchen compost, and your on your way to having more to add next year. My other two thoughts are you may find once it gets hot, it's drying out too fast. Adding a mulch will help, plus be adding for next years total. As far as next year. I don't have a crystal ball, but I'm imaging these boxes going higher, building the same box shape, just adding it on top. Doing it all at the start is just too much expense. I'm so curious how this is going to work where you are. What fun ! Here is a link that might be useful: The promised link

Most tree roots left in the ground after cutting/harvesting need both even soil moisture and an active soil microbial population to break down and decay. And wood is not a fast decaying material anyway, as the tannins, lignins, resins/turpins, etc., most woods contain make digestion/decomposition a very slow process. That's why wood-based mulches are much favored :-) btw, sweetgum (Liquidambar styraciflua) wood is rather desirable for a number of reasons. Sweetgum is one of the most important commercial hardwoods in the Southeast and the handsome hard wood is put to a great many uses, one of which is veneer for plywood. The wood is very compact and fine-grained, the heartwood being reddish, and, when cut into planks, marked transversely with blackish belts. Sweetgum is used principally for lumber, veneer, plywood, slack cooperage, railroad ties, fuel, and pulpwood. The lumber is made into boxes and crates, furniture, radio-, television-, and phonograph cabinets, interior trim, and millwork. The veneer and plywood are used for boxes, pallets, crates, baskets, and interior woodwork. Being readily dyed black, it is sometimes used instead of ebony for picture frames.

Hi Ch3rri, Yes, I have been growing figs in my hometown and now own a huge fig tree in a big container. In your zone, you could try plant them outdoors. Otherwise, you made a big mistake, I am wondering where you are going to keep them. They grow like weeds and drink gallons of water each day. Fig is very different than other trees you and Jay grow, it's a lot easier than the sugar apple, not even mentioning the mangosteen. Fig is genetically vigorous. This one you can relax a bit. Mine is only four years old, but the trunk is over 3 inches now. I got over 300 figs last year, this thing keep doubling its size each year. I have only one and I am concerned about how I am going to move it end of this year. And how many you have? Three? I am imagining what you are going to do when they get big after two years. You should double check on the pH issue. Figs actually love sweet soil, that's why in my hometown, we put lots of lime and Italians mix concretes into the soil. This is to raise the soil pH. Another issue is to fight the damn squirrels and birds. They will know before you do that some figs are ripe. They will try to test a couple each day.
