Self Irrigating Pot Patent from 1917

I’ve often blogged about the convenience of self irrigating pots (SIPs), containers that have a built-in reservoir of water at the bottom. They work well for growing vegetables on patios and rooftops. You can make your own or purchase one from several manufacturers. I had thought that Blake Whisenant, a Florida tomato grower and Earthbox company founder, had invented the SIP in the 1990s, but it turns out that the idea came much earlier....

Testing the Lead Testers

...d us an email at [email protected] or leave a comment. We’re attempting to reconcile slightly different lead results from three different labs and I’d like to be able to write about soil testing methods. Two of the labs we sent samples off to (UMass and Timberleaf Soil Testing) use inductively coupled plasma mass spectrometry (ICP) to test for lead. Wallace labs uses an extractant, AB-DTPA (ammonium bicarbonate Diethylene Triamine...

How to Process Carob

Before. Photo by Bill Wheelock. Our neighborhood has an abundance of carob (Ceratonia siliqua) trees that, around this time of year, drop thousands of pounds of pods. Now many of us may have unpleasant associations with carob as a 1970s era chocolate substitute, but the tree has a long history in the Middle East, where it’s used to make a tea, as a source of molasses, as a vegetable and as animal feed. The “locusts” th...

Ridiculous Press Release Tuesday

I’m not making this up I’m getting so many off-target press releases clogging my inbox that I’ve decided to share them until the publicists who send them get a clue and actually spend some time reading this blog. One release in particular should get an award for crassness. The American Dietetic Association has, apparently, teamed up with industrial food giant ConAgra (am I the only person who sees that pairing as a con...

Shiitake Happens

Well, actually, shiitake doesn’t happen. It’s back to the drawing board for our first experiment in mushroom growing. We ordered a kit and dutifully followed the directions, but a combination of high temperatures and too much or too little water resulted in the result you see above, what looks like a cake with a skin disease. And even if we got a crop the cost of the kit was too high to make the process economical. The kit came pre-...

Sunset Magazine’s Take on Zones

A Sunset Magazine zone map Yesterday we posted a USDA zone based vegetable gardening planting guide. But the problem with USDA zones, as many readers pointed out, is that they aren’t specific enough. For instance, all of the city of Los Angeles is in USDA zone 10, but the difference between where we live and the coast is significant. This is where Sunset Magazine’s more detailed zones maps come in handy. Sunset has divided t...

Behold the Western Electric 500

There’s much to love about the Western Electric 500 telephone. It’s easily serviceable and built like a tank. Why? When it was manufactured you didn’t own your phone, the telephone company leased it to you. This relationship served as a powerful incentive to manufacture a device that would last. In the 90s I went through three or four cheap cordless phones that broke after a few months of service. I switched back to an old tou...
