Our Grape Arbor is a Stacking Function Fail

floorgrapes

Grapes on an arbor over patio furniture: what could possibly go wrong? It’s the very embodiment of the permacultural notion of “stacking functions.” The grapes provide both shade and food. The fantasy was to spend the summers like a Roman emperor, reclining on a couch and occasionally reaching up to grasp a succulent cluster of grapes.

Let me, however, add a few a few unsavory slices to this permacultural sandwich (in addition to the delusions of grandeur): rats, mice and squirrels. All day and night hungry mammals rain down half chewed grapes. And the freak rain over the weekend, combined with a few days of heat and humidity, got some very funky fermentation going. It’s like something out of my inner Martha Stewart’s worst nightmare.

I wish I had a conclusion to this post with a miraculous solution, like say specially trained roof Chihuahuas. I don’t. I do wish that the non-fruit producing Vitis californica vine that grows along our northern fence could be swapped with the prodigious one on the arbor. If fruit grew on the fence vine I could more easily net or cage it, or it least thin it out without having to move a ladder and patio furniture around.

As always, I’m open to reader suggestions or just commiseration . . .

Emily, We’ll Miss You

Baltimore, you are about to receive a gifted writer and journalist. Los Angeles, we’re losing Emily Green.

Green was on episode 20 of our podcast to discuss how to shift the mow, blow and go landscaping paradigm here in LA. Green wrote often about this problem as well as the consequences of climate change in our region. She’s was unafraid to take on LA’s corrupt and hypocritical politicians. Her voice here will be missed and there’s no replacement.

I hope she’ll keep up her blog Chance of Rain. If you haven’t visited lately, you should check out her excellent twelve part series, After the Lawn.

LA Observed has a tribute to Green, Goodbye to all this.

051 Toilets and Poultry

On episode 51 we listen to a comment about toilets from Eric Rochow of Garden Fork TV. Eric mentions a podcast episode of Tiny House Chat where they talk about composting toilets. Then we discuss poultry biosecurity lessons that “West Coast” Erik learned at a recent conference. So, yes, toilets and poultry! Take that Elon Musk!

How do I keep squirrels and rats from eating my grapes?

My beautiful picture

I’m running an experiment this summer on our grape arbor. Using our CritterCam, I’ve photographed both squirrels and rats munching on grapes. I decided to see if either paper bags or plastic clamshell containers would deter the daily and nightly mammalian fruit buffet. Preliminary results:

  • Clamshells don’t work. The fruit fermented, and not in a nice way.
  • Paper bags seem to work, but probably only because I left a lot of the fruit exposed in the hopes that they would eat that first and leave the bagged fruit alone. It’s also hard to tell when the fruit is ripe when it’s in a paper bag.

I’m thinking the long term answer is to make custom fruit cages out of hardware cloth. If the grapes were neatly tended on a vine it would be much easier to net them. Netting is not an option on our arbor.

Look carefully in this image and you can see one of the “perps” reaching out to grab a tasty grape:

Have you tackled the mammalian grape buffet issue? How did you deal with it?

So Cal Alert: Polyphagus Shot Hole Borer

Polyphagus Shot Hole Borer, from UC Riverside’s Eskalen Lab

Seems the greater LA area is ground zero for the introduction of yet another exotic beetle which is killing our our beautiful native oaks and sycamores, our landscape trees, even our beloved avocado trees.

The good news is that the fungal disease propagated by the beetle can be treated if detected early. You’ll need the services of a professional arborist, but the cost of treatment will likely be less than the cost of tearing out a mature tree.

Look at this link to UC Riverside’s Eskalen Lab. Here they have several PDFs on identifying and treating the disease. They also have a map showing the spread of the disease. Of course, these are only reported infections–it could be much more widely spread.

(Note: a separate invasion was recently detected in the commercial avocado groves of San Diego county, so folks further south should be on alert too.)
