Gardening where the sidewalk ends

Planter Barrels September 6, 2008

Not ready to commit to ripping out your entire parking strip or building a big raised bed? You can take baby steps towards colonizing this valuable growing space by putting out a few inexpensive half-barrel planters to catch the sunlight for a small selection of veggies and flowers.

Here is an example from my neighborhood:

Barrel planters

This garden is also on a fairly decent slope, so perhaps the ground had to be dug out a tiny bit so that they would be level. Other than that, it looks like they were pretty much just plunked down and planted.

Raise High the Planter Beds, Carpenters August 28, 2008

(Sorry, gratuitous Salinger reference there…)

In my previous (and very first) garden, the only patch of ground that was free of summer-long shade was on the street, in the parking strip. So, if I wanted a few veggies, herbs and strawberries to nibble, I had no option but to garden out there. Not being too handy, but feeling like a raised bed was the best way to contend with tree roots and crummy soil, I pondered the options. My mom ended up getting some friends to build me one as one of my all-time best ever birthday presents. I got a lot of fun and use out of it, and was really bummed to drive by our old house recently and see that the new owners had dismantled it for some unknown reason. Maybe I should ask if I can have the pieces back, to rebuild it (by myself, this time) in our current place…

Here are some links for building raised beds. I’m not going to reinvent the wheel here, just providing some options.

Sunset Magazine has a fairly simple design, and they claim it can be built with redwood or cedar for under $200. Does require a table saw, though.

Here’s a really spiffy one, from This Old House. Pricier too, though, and probably needing someone pretty handy to put it together.

Prefer a video? This is kind of goofy (bonus for dog-lovers, cute labs co-star, chasing sticks and a frisbee), but shows how to make a planter bed with untreated 2 X 12’s, coated at home with linseed oil. Tells you how to mole-proof, too.

This is a Texas A & M University (Ag school) article, ” In Praise of Raised Beds,” with advice about how big to build yours and how to prepare the ground, what soil to add, etc.

Treated wood is icky. Nobody knows for sure what it leaches into your soil, so try to avoid it if possible!

Here’s an example of some raised planter beds in our neighborhood:

Raised beds

Small crosswise ones allow you to reach in and not have to step on and therefore compact the soil.

This one is a small square bed, great for a vertical crop like beans or peas plus whatever you want to plant around the edges.

Small raised bed

You can also forgo wood altogether and make a bed out of paver bricks or broken concrete (scroll down in the latter link to see a nicely formed herb bed using this method). To be legal with the city, at least in Seattle, raised beds in the parking strip require a permit, and bricks or stones must be fixed in place, not removable for easy hurling.

Raised beds make root crops like carrots and beets much easier to grow, and in an urban setting, adding your own soil from a known safe source is a plus too. Before you set up your bed, be sure to double-dig or rototill the existing soil to help with drainage. And don’t forget to add lots of compost! Anyone have a favorite? Mushroom compost? Something containing bat guano, perhaps? Or just home-grown?
