The Fine Art of Determining Peach Ripeness

IMG_1072

How do you know when your peaces are ready to pick? For home growers it’s all about color. According to the University of Georgia,

Ground color is the best field indicator of peach maturity. . . The ground color of a peach approaching maturity is light green. A break in color toward yellow is the first definite indication of maturity. Brightening of the red over-color of the skin is another, though less reliable, index of maturity. Red color is typically dull prior to the green to yellow break. When the underlying ground color breaks to yellow, the red brightens and can easily be selected. Color judgments are reliable with many older varieties, but new highly colored varieties with higher percentages of red over-color have diminished the usefulness of color in maturity determination.

Farmers have access to a few tools that can make ripeness determination easier such as this expensive gadget that measures firmness or a brix meter for determining sugar content. These tools could only be justified if you were planning on growing, shipping and selling fruit. More useful for us backyard growers is this gallery of peach fruit color stages.

I’ve been picking them a little on the green side and letting them ripen inside in order to stay ahead of the squirrel menace. This year we’ve eaten a lot more peaches than the squirrels have.

How to Squirrel Proof Your Fruit Trees

IMG_7297We’ve been guilty in the past of claiming that growing fruit is labor-free. That’s a lazy blogger’s lie. The truth is that you have to stay on top of pruning, irrigation, fruit thinning, fertilizing and pest prevention if you want to harvest any fruit. After not getting a single peach off our small tree last year due to squirrels, I vowed to do things differently this year.

I considered a number of squirrel prevention techniques:

  • Metal collars on trunks. This doesn’t work, especially in urban areas. Squirrels are superb acrobats and can simply jump from a roof, fence or adjacent tree on to your fruit tree.
  • Trapping, killing, hunting. I don’t have the heart to do this and it’s illegal in urban areas but it is what professional orchardists do.
  • Electronic or visual frightening devices. According to UC Davis, these don’t work. Squirrels aren’t dumb.
  • Dogs. Maybe, but it depends on the dog. Our late doberman was more interested in alerting us to the mail carrier’s rounds. He was more interested but, ultimately, unsuccessful in his 13 year battle against skunks.

Exclusion with plastic bird netting is the most promising technique for urban areas. In order to do this you need to keep the tree pruned to a manageable size. I purchased a 14-foot by 14-foot piece of bird netting and Kelly and I put it on the tree (it’s a two-person job as bird netting is a pain to work with). We secured it with clothes pins. You must be absolutely certain to leave no gaps in the net. If you leave a gap you could trap birds and the squirrels will also work their way in. The next step is to keep a close eye on the fruit and harvest it as soon as you can, perhaps a little sooner than is ideal.

Unfortunately, squirrels can easily chew through bird netting so this method is far from foolproof. According to UC Davis, exclusionary methods will only work if the squirrels have other things to eat. Another argument for biodiversity in our landscapes, I suppose.

If you know of any foolproof squirrel prevention techniques please leave a comment!

Our guest this week is journalist Kris De Decker, the creator of Low Tech Magazine, a blog published in English, Dutch and Spanish that covers low tech solutions in great depth and detail. Without exaggeration, I think it’s safe to say it’s my favorite blog. On the podcast we discuss high tech problems, Catalan vaulting, fruit walls, Chinese wheelbarrows, open modular hardware, fireless cookers and alternate forms of the internet.

I picked a peck of pickled peaches

IMG_7181Each year I thin our peach tree to assure that, in a month, the squirrel population will access only the largest and most succulent peaches. The other reason to thin a peach tree is that if you don’t it will collapse of its own weight, like those industrial broiler chickens that can’t stand up if you let them live past the eating stage.

But what to do with all those immature peaches? Yes, you can pickle them. This I learned from Kevin West’s bible of food preservation, Saving the Season. In the introduction to his pickled green almond recipe (p. 103) West notes that immature stone fruit such as peaches and nectarines can be pickled in the same way as green almonds (almonds are a stone fruit too).

If you don't thin this branch it will break off.

If you don’t thin this branch it will break off.

I’d share Kevin’s recipe with you but he’s a fellow author and you really should own his book, Saving the Season. It’s the classiest food preservation book out there. Plus Kevin could have me killed and pickled (just kidding). What I can tell you is that this is a quick, vinegar powered refrigerator pickle. Any similar vinegar pickle recipe will work. West’s recipe calls for white wine vinegar. I ran out and substituted the vinegar you clean floors with. Nevertheless, they came out fine and resemble large olives.

Should you want to try pickling green almonds, by the way, you can sometimes find them in Middle Eastern grocery stores and some farmers markets (our local Armenian supermarket Super King sometimes has them if you can survive the infamous parking lot).

069 Understanding Roots with Robert Kourik

Robert-Kourik-with-Roots


What do roots tell us about how to take care of plants? That’s the topic of this week’s Root Simple Podcast with our guest Robert Kourik. Kourik is the author of many books including Designing and Maintaining Your Edible Landscape Naturally and Drip Irrigation. The discussion begins with the remarkable tree root diagrams pioneered by Dr. John Weaver in the 1920s and 30s and featured in Kourik’s new book Understanding Roots. From there we touch on how to plant fruit trees and the intricacies of how to water trees, vegetables and native plants. Then we delve deep into drip irrigation, dynamic accumulators and phytoremediation.
