Least Favorite Plant: Euphorbia tirucalli

...e escaped any permanent injury. Ironically, for such a toxic plant, it has many uses, both historical and proposed: Plant blogger Mr. Subjunctive included it in his list of useful houseplants to fend off zombies with over at Plants are the Strangest People. It’s been proposed as a cancer cure, I suppose because it’s so nasty that you’ll forget you have cancer. Africans use it as a mosquito repellent and fish poison.  Petrobas,...

My mental glitch: hay vs. straw

...i-fi”. * Homegrown Evolution readers are all savvy folks, and know this already, but in case some poor soul is cast on this shore by Google, this is the difference between hay and straw: Hay refers to grasses or legume plants cut down fresh and baled for animal feed. Hay bales are usually greener than straw bales, the plant material finer. Hay smells really nice, too. You would not want to use this stuff as mulch, or you’d end up...

Perennial Vegetables

For lazy gardeners such as ourselves nothing beats perennial vegetables. Plant ‘em once and you’ve got food for years. For novice gardeners, perennials are plants that, unlike say broccoli (an “annual”), don’t need to be replanted every spring. The best known perennial vegetable in the west is probably asparagus which, given the right conditions, will produce fresh stalks for years. But there are many thousands more...

The Cat Poop Portal: Litter Box Composting, Installment #1

...rdinary composting is that we’ll let this compost rest for two years before we spread it, to be sure the bad beasties die off. And in case they aren’t gone, we won’t spread the finished compost around edible plants. No, this is not orthodox practice. It is not considered “safe” to compost pet waste–all the standard advice tells you not to– but we’re doing it anyway, because we trust time and bacteri...

Nursery Customers From Hell

We’ve been going to Sunset Nursery since we bought our house fifteen years ago. The staff has always been polite and helpful and they have a diverse selection of plants. On a whim, Kelly took a look at their overwhelmingly positive Yelp reviews. But some of the Yelpers prove how hard it must be to work in a nursery and deal with a public that can charitably be described as disconnected with the natural world.  Take this Yelper: I’ve...

Winter Squash Disaster

Those of you who follow this blog may recall last summer’s “squash baby” fiasco.  This year I planted a few Marina di Chioggia squash plants (technically a pumpkin) in one of my vegetable beds located in a more secure location. Instead of some homo sapien making off with my squash bounty, it looks like the neighborhood raccoons are having a gnocchi party somewhere. All I’ve got to show for three Chioggia plants is one sm...

Five Lessons We Learned About Lead in Soil

...nology.” It’s the idea that there just has to be a technological solution to every problem. This is a very common fallacy in our age. Some people have suggested that I try phytoremediation, the process of growing plants like sunflowers that accumulate lead. At the end of their growing cycle you pull the sunflowers and send them to a toxic waste dump.  Sadly, this is just not practical in a residential yard. I would have to pull ever...
