Actually these were very easy to build. 4 used cross ties and some treated 2 by boards for the ends. Stacked ties, 2 on each side, tied together with the treated 2X material for the ends, makes 'em about 8' x 3' inside. Fill 'em with compost, you have the width of the tie as a seat when you work the plants. Ours are at least 10 years old. Add compost as needed, about every other year. The mushroom compost will not retain moisture so you have to keep watering the plants in the raised beds about every other day when it gets hot.

Yes I like the raised beds. They're easy to get to and maintain. Plus I don't have room for a larger garden. I haven't done much with mine this year though. Y'all are making me want to get out there and put in some tomatoes :>) I've been so dang busy though I hardly have time to rake up all the leaves in my yard.
Here's an update on Panhandle gardening. IT'S WET!!!
Planted 7 rounds (that's 14 rows) of red corn Thursday along with 2 rows of yellow straight neck squash. The rain started that evening and as of this afternoon we've had 9.4" of rain. It will probably be a couple of weeks before we can replant. Most likely the seed will rot and most the fertilizer will be leached out.
The raised beds will be getting a lot of attention this week if the rain has stopped. Forecast is for rain to begin in the middle of the week.
Got a few pictures showing what it looks like and a neat picture of the west edge of the last storm this afternoon. There is a dove sitting on the power line and the 1st blue sky since Thursday, made me think of the account of Noah in the Bible, releasin' the dove from the ark.

Yes the weatherman was WRONG. They said we should have 3 days of rain this weekend in west central fl. Not. The panhandle got hammered with all that rain. We got maybe half an inch.
Beans, corn, tomatoes are growing well. Having issues with zucchini and squash. Planted 8 seeds and only 2 popped up in 2 weeks. I replanted 6 more seeds, now I have to wait another week and see what happens to these.
Well in central Florida our garden is doing well
Potatoes and beans 
Lettuce and beets
Tomatoes
I tried planting beers none came up yet
