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 . . .

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?

Extreme Measures: Squirrel Proofing Your Fruit Trees

I’ve been thinking a lot about this fruit tree cage that Kelly spotted on the Theordore Payne garden tour this spring (see some more images of that lovely Altadena garden here). Squirrels just stripped our peach tree of every single fruit (though I’ve found that I can still eat the half-gnawed ones I find on the ground). Other options I’ve considered:

  • Bird netting. But this stuff is a real pain to work with. And it doesn’t always work. Squirrels are persistent!
  • Removing fruit and ripening it indoors. I did this last year with some success, but I was not on top of the situation this year.
  • Squirrel stew. I just don’t have the heart for this option.

I think there’s a way to make aesthetically pleasing fruit tree cages. Crazy idea: what if they were as carefully crafted as Robert Irwin’s running fence piece at UC San Diego? It’s too late to fence the trees in our own garden, but I think if I were planning a new garden I might try to find a way to make those fruit tree cages look like 70s era land art.

How do you deal with the squirrel/fruit tree menace?

My Apologies to the Skunk Community

For years I’ve blamed the nightly vegetable carnage that takes place in our raised beds on skunks. The other night, our CritterCam (a Wingscapes BirdCam Pro), revealed the culprit: raccoons. And they work in pairs trios!

No wonder it’s been so difficult to secure the beds! Given the strength and agility of Racoons, I’m surprised that bird netting has worked at all (though, I’ll note, only when that netting is firmly secured with many staples). Perhaps it’s time to consider escalating to metal wire.

The “citizen science” lesson this week: raccoon and skunk diets overlap considerably. Both are highly adaptable urban foragers. In the case of our raised beds, both the skunks and raccoons are digging for figeater beetle larvae (Cotinis mutabilis). These huge larvae must be a delectable treat, the equivalent of a raccoon and skunk sushi party. Maybe I should overcome my squeamishness and join in the nightly feast. A plate of Cotinis mutabilis larvae ceviche could just be the next hip LA food trend . . .

Ways to Critter Proof Your Vegetable Beds: A Competition

Day and night superimposed: bird netting fail!

Root Simple is proud to announce our equivalent of the X-Prize. No, we’re not asking you to figure out a low tech method to catapult rich silicon valley executives into the vacuum of space. What we’re looking for is a means to mammal proof vegetables beds that is:

  • Convenient
  • Effective
  • Attractive
  • Wildlife friendly
  • Easily disassembled in the off season

Note that we’re going to be particularly stringent in judging the aesthetics of the solution. Mrs. Homegrown has an M.F.A., and is a blistering in-house art and design critic around our little homestead.

Participants can leave a comment on this post linking to an image, or send us an email at [email protected] The winner will get a package of our newest publication–a series of booklets we wrote in collaboration with the Ecology Center in San Juan Capistrano.

I will also be participating in this competition which does seem unfair, but we’ll let Mrs. Homegrown be the judge.
