I few more details on the plans that I posted above: The raised beds along the fence would be completely separate from the fence, I'm not talking about heaping dirt against the fence or anything like that lol! Just building raised beds 2' wide and placing them against the fence so I can grow vertically as much as possible. I have a 50' roll of black vinyl coated chain link fencing (part of it is used to enclose the current garden) and I plan to repurpose it by hanging it along the back fence so I can trellis peas, beans, tomatoes, melons, whatever. I have been reading that growing vertically is one way to get more out of a small space. Since I have two medium sized dogs and I have learned the hard way that regular garden fencing or poultry wire isn't really sturdy enough, I was planning to buy some hog panels, have them cut in half, and have those go along the front of the beds to keep everything out. Hog panels are 34" tall and the bars are close together at the bottom and gradually get further apart as they go up. Each half would weigh about 17 pounds, so I can lift a section off as needed to tend the garden, then put it back up when I'm done. The design I came up with has a 4' tall 4'x4' fence post between each bed, about 2' feet out from the existing fence posts. The end pieces of each raised bed will be screwed into it, and once the 1' tall beds are filled with dirt, it should be plenty sturdy enough to support these panels. I also intend to have a piece of 2"x4" going between each of these posts and the actual fence posts to lend greater stability to both, and that will be the only thing that connects the raised beds to the fence. I thought it would be best to keep them totally separate to allow the fence to be worked on or even replaced later if needed, without having to remove the beds. The center beds would need a different setup for keeping out the dogs and rabbits. I had in mind some kind of enclosure that goes around the perimeter, with a gate at the opening. Most likely I would use the same hog panel idea so I could access the beds from the outside or the inside, or I could opt to leave part of it in place and use it for a trellis. I have thought about even enclosing the whole thing with heavy plastic to create a greenhouse for winter, and I could also use it to suspend shade cloth since the sun is a bit too much here in Oklahoma in the summer and it actually gets hot enough that the tomatoes stop setting fruit. The only thing I don't like about this idea is that it is right in the middle of the yard (actually, two of them, one on each side) though the dogs would have a blast running around them. Aesthetically, I think the perimeter beds along the fence would be more attractive and open, even with the smaller island beds added. I would probably put just low covers on those and use those beds for low growing crops since I would have plenty of space to trellis the taller crops along the fence. Thank you for considering my ideas and if you have any feedback or suggestions for me, please let me know! Here is a link that might be useful:

Before I'd make that ^ pronouncement, I'd question OP about what is meant by a 25 ft. limit in size. I'm about as sure as a guy at a computer at a remote location can be that what he/she means is that the yard section or whatever little plot this is is 25 ft. wide. That simply does not say anything about what tree can or can't "fit" that spot. Remember dear readers....large-growing "shade tree"-type trees, when mature, exist as a trunk somewhere out in the yard. The trunk may grow large, but no tree I'm aware of in the N. temperate zone is going to have a trunk 25 ft. wide. What is almost surely the case is that any large-growing "shade tree"-type tree could in fact easily inhabit that space...and at maturity, would consist of a trunk with all the tree up high overhead. Such trees form living ceilings over our "outdoor rooms" which is what landscaping seeks to provide. Take that same 25 ft. wide area, plant one of the ornamental, low-crowning species, and now you really have taken up all that space. Nobody can throw a ball around, nobody can even just walk there, because there's a big, wide-spreading ornamental tree crown in the way. That's the reality of this big tree/small tree conundrum-that many folks get it exactly backwards-the large-growing type-at maturity-taking up less space than the little redbud, fl. crab, or what have you. People that give out lots of landscape advice should learn to recognize this elemental fact.

Celerygirl, as much as I like the blue-grey, I'm not sure I would want that color on my house. It would go well with the neighborhood. If I'm going to change the siding, I would select a earthier, lighter color. I usually gravite towards weathered cedar grays but I guess it wouldn't go with the brick. I wish my husband would let me me paint the brick. Out of the three options I think I prefer the all brown color schema. Maybe I can change the white vinyl for some sort of matching brown vinyl cedar shingles? Thank you all for your help!
