Big, bad asbestos and your garden

As though the warnings about lavender and tea tree oil that I summarized in the last post weren't enough, the July 8 issue of Science News has this article: Dirty little secret: asbestos laces many residential soils (available online for non-subscribers). We're not talking about houses built on old waste dumps, either. Asbestos is a mined mineral, and when asbestos-containing deposits are found near the surface, disturbances (such as the housing development described in the article) can send the cancer-causing fibers flying. Though the fibers in question are larger and don't drift as far as those released from old insulation materials and other asbestos found in old buildings, they do pose a risk when they're kicked up by wind or machinery. Unfortunately, though asbestos use in construction and its removal from old buildings are highly regulated, there are no laws restricting construction on sites where veins of asbestos-containing minerals have been uncovered.

But even if your home isn't built on a tremolite vein (one common asbestos-containing mineral), concerns about asbestos contamination of vermiculite mines a few years ago had gardeners and horticulturalists up in arms. Vermiculite, of course, is the stuff put in potting mix to lighten it while helping retain water. Experienced gardeners know you can buy it by the bagful if you want to create your own potting mix. It's also mixed into fertilizers, and has dozens of commercial and industrial uses, from fireproofing to nuclear waste disposal.

So what's a gardener to do? If you use vermiculite, the EPA recommends these steps to reduce exposure to the dust:
  • Use vermiculite outdoors or in a well-ventilated space (outdoors is best).
  • Dampen vermiculite before using it to prevent dust from flying.
  • Use purchased, moist potting mixes to reduce total vermiculite exposure.
  • If using vermiculite outdoors, peel off outer layers of clothing before going inside, and wash them.
A dust mask might not be a bad idea, also.

The National Cancer Institute has more recommendations for reducing cancer risk from asbestos.

Lavender and Tea Tree Oil: Estrogen Mimics

I posted a summary of this on the You Grow Girl forums. The July 1 issue of Science News carried an article about the newly-discovered feminizing effects of lavender and tea tree oil in young boys, and appear to be responsible for a rise in breast development in pre-pubescent boys. The article is on the Science News website, but is available only to subscribers of the print magazine, so I'll summarize the findings here.

The story: Ever since 1990, Dr. Clifford Bloch, an endocrinologist in the Denver area, had been seeing a number of cases of gynecomastia in pre-pubescent boys. Gynecomastia, or breast development in boys, is unusual, and when it occurs it's usually the result of some hormonal problem. However, testing the boys for sex hormones showed a normal ratio of the various sex hormones, so it wasn't a hormone production problem. After a great deal of laborious detective work, trying to find out what these boys all had in common, the doctor traced down two possible culprits: lavender essence and tea tree oil. All the boys had been using soaps, hair gel, shampoo, and similar topical products with these two herbal ingredients. In some cases, boys had been putting pure lavender oil on their skin. When Bloch suggested they stop using these products, the condition disappeared within a few months.

But a simple correlation doesn't prove a cause, so the doctor contacted a health sciences research lab in North Carolina, and asked them to investigate. The researchers carried out an in-vitro experiment, treating human breast tissue cultures with lavender or tea tree oil. In both cases, the oils caused the cells to turn on estrogen-regulated genes and turn off androgen-regulated genes. In other words, both act as estrogen mimics, turning on genes normally controlled by estrogen, such as genes that stimulate breast tissue growth. It also turns off genes controlled by male hormones.

While Bloch's observations were on young boys, the same effect may also happen in young girls. In fact some health researchers have noted a recent rise in pre-pubescent breast development in girls. With the increased popularity of lavender as a calming aroma in aromatherapy, more people are using lavender-scented products, and users include children in the household.

The article had no report as to whether spammers will soon be pushing breast enlargement products featuring lavender and tea tree oil. It probably wouldn't work, either. Kids have such low levels of sex hormones that the small amounts of estrogen mimics in these oils may be upsetting the balance, but adults may not even notice the difference. However, women with or recovering from estrogen-related breast cancer will also want to take note of this article, and discuss it with their doctor.

Moral of the story: enjoy lavender and tea tree oil now and then, but don't overdo it. And for pity's sake, don't let your kids slather lavender oil all over themselves. Even without the hormonal problem, it's a bit much.

Free shipping from Dutch Gardens until September 15

The heat of the summer may not seem like the time to think about fall planting, but if you have special bulbs in mind, it pays to order early before they're all sold out. Today's email brought a letter from Dutch Gardens that says they're offering free shipping between now and September 15. Hmm, ordering early pays in more way than one. Dutch Gardens offers a good selection of tulips, narcissus, and many of the smaller bulbs. I've ordered from them for quite a few years now and I've always been satisfied with their quality and their prices.

The garden in July

Even though it's stinkin' hot out there, I did get outside to get a few garden pictures.

First, a look down the lovely throat of a lavender poppy, with its lovely pale crepe-paper petals. I shall save seeds from this one -- I had many more in the past, but this is the only one I've spotted this year:
And as for the lavender itself, it's blooming away like mad, and the bumblebees are having a marvelous time all over it:

The hot border in front, blazing away in a mass of scarlet sage and bright yellow coreopsis. There's Moonshine Yarrow peeping around the edge of the sage, barely visible:

And the Dierama, or wand flower, sending up its long stalks with charming little purple flags waving from them:
Now if it will only cool down enough for me to go and chase the weeds. They're having their way with things all over the garden again.

Currant Jelly

From gorgeous fresh currants like these...


...comes magnificent, anti-oxidant-loaded, extremely delicious jelly like this:


But alas, as my entire harvest from my one-year-old currant bushes was all of one quart of mixed red, black, and white currants (mostly red and white), including stems, that's all the lovely currant jelly I got for this year! It was worth it, though, and the last of it adorned my English muffin this morning.

The jelly is about the easiest jelly I've made, since currants have plenty of pectin in them and don't need additional pectin to jell. In fact, I cooked this batch just a little too long and my jelly had almost the texture of jujubes. Took a bit of energy to spread the stuff. But oh, it tasted good.

Here's how to make it:

Start with several quarts of fresh-picked currants of whatever color you fancy, or a mixture therof. Don't bother to pick off the stems, since the whole mass will be strained for the juice. Put in a kettle with a little water, turn the heat on medium, and simer until the berries are soft. Mash a bit with potato masher or a whisk for more juice (or leave them be if you want the clearest juice).

The best thing to use to strain the juice is a jelly bag. If you don't have one, cut a big, big square of cheesecloth. Two single layers will do. Place the cheesecloth in a collander, and place the collander in a pan. Pour your juicy cooked currants in the collander. Let most of the juice drip through, then gather up the edges of the cheesecloth, tie with string, and hang from a knob on a cupboard over the pan and let it drip. If you want, you can squeeze the bag to get every last bit of juice out of it, but if you'll get the clearest jelly if you don't.

Measure the juice. For every cup of juice, add one cup of sugar. Put no more than 4 cups of juice and sugar mixture in a heavy-bottomed pan on the stove and bring to a boil, then reduce the heat and simmer. To test to see if the jelly is done, take some up in a large spoon and let it pour off the side. If it dribbles thinly, it's not ready, but if it pours in one semi-thick mass from the spoon, it's ready. Or dab some on a very cold plate and see if it sets up. My jelly took about 5 minutes to reach this stage. A full 4 cups should take 8-10 minutes. But do test from time to time.

To preserve the jelly, pour into clean, hot, sterilized half-pint jelly glasses, leaving about 1/2 to 1/4 inch of space from the top. Place a clean, hot lid on top and put on a screw ring tightly. Turn the jar over and let it cool completely. This nearly always creates a seal when the jar is turned upright again. Don't try to seal a half-jar of jelly. Instead, put it in the refrigerator for your morning muffins.

Red, white, and blueberry pie

Now that's what I call dessert. I'm taking two of these beauties to a 4th of July picnic tomorrow. The blueberries came out of my garden, but alas, I had to go buy the strawberries since my plants just went in this year and aren't producing well yet. All it needs now is a decorative bit of whipped cream for some visible white -- though there's white creamy stuff under the berries.

Here's how you can make one yourself:

Red, white, and blueberry pie

Start with one pre-made graham cracker or cookie crumb pie shell, store-bought or made yourself.

Put one 8 oz package of lowfat cream cheese in a mixer. Blend with about 1/4 cup powdered sugar (more or less to taste), 1 teaspoon of vanilla, and 2 tablespoons of milk. Whip until smooth and creamy. Spread on the bottom of the crust.

Wash 1 quart of strawberries. Remove the hulls. Place pointy-side up in the cream cheese. To make cutting the pie easier, I cut the berries in quarters, but keep the quarters together as I press them into the cream cheese.

Sprinkle about 1 cup of blueberries over the strawberries.

For the glaze, mix 1/3 cup of sugar with 1 tablespoon of cornstarch and 1 tablespoon of strawberry gelatin mix in a small saucepan. Mix in 1/3 cup of water. Bring to a boil, then boil 1 minute. Use a gravy ladle or large spoon to pour the glaze over the berries. Refrigerate 1-2 hours or overnight. Garnish with whipped cream.

(If you buy a crust, save the plastic liner. Turn it over to make a nifty pie cover to protect your masterpiece if you have to transport it somewhere. Just lift the edges of the pan as you had to do to remove the plastic, put the "lid" in place, and push the edges of the pan back down again.)

We're havin' a heat wave...

June began cold and wet. Last week it was pleasant -- partly cloudy, mild temperatures.

Today, as I write, it's 92 degrees. Tomorrow it's supposed to get over 100.

I intended to do some late planting of annuals in the front garden, but the soil there is bone dry and just as hard, so I finally dragged out the sprinkler hose and it's getting a thorough dousing. The whole bed needs renovated, so there's no point in planting any seeds until I at least get some cow stuff dug in around the places I want to plant. Otherwise it's going to get just as hard again when it dries out.

The lettuce bolted, the peas that I planted back in February (Planting Peas, Striking Gold, Pea Sprouts and Peach Blossoms) are at the end of their productivity, so pulled both out. I planted new lettuce seeds, some where the old lettuce had been, some in the shade of the now-towering asparagus, to see if it would do better there in the summer's heat. Alas, the peach tree got hit with a bad case of leaf curl, so all those lovely blossoms never had the chance to produce a peach. But the broccoli and cauliflower that I started from seed (Bouncing Baby Broccoli) are doing nicely so far. I gave them a good watering.

I'd put up some pictures, but it's too stinkin' hot out there right now. Maybe I'll get some in the morning.

A Chocolate Garden

I was looking for several things on Amazon.com when I came across this interesting product: Chocolate Garden.

It's a tin containing seeds of chocolate covered perennials, to wit: " Chocolate Flower, Chocolate Columbine, Midnight Candy Phlox, Chocolate Royale, Chocolate Nasturtium and Royal Chocolate Painted Tongue." A chocolate-loving gardener's delight!

While it's rather late in the season to start seeds for this year's garden, in warmer regions gardeners could start perennials to plant in the fall and overwinter for next year's blooms. Or put this one on your "wish list" for Christmas.

Green Blog Project

Foodie gardeners will want to check out Ginger and Mango: Green Blog Project. The author wants her readers to grow something themselves, make something to eat out of it, and post the picture of what they grew along with the recipe. This was just a quiet little food blog, but the Green Blog challenge seems to have upped the traffic many-fold. What food-loving gardener could resist?

Happy Father's Day (you all did remember, right?)

"Fatherhood is pretending the present you love the most is soap-on-a-rope."
Bill Cosby
You know, I remember a few of those infamous rope-bound soap bars appearing at Christmas back when I was a kid.

Please tell me it wasn't me who gave them.

Happy Father's Day, everyone.

Urban Farmers vs. the Bulldozers of L.A.

Once upon a time on 41st and Alameda Street in South Central Los Angeles, a garden arose. Not just any garden, but a community garden, where the people in a low-income neighborhood gathered to grow food and so feed themselves. And it was good.

Until now.

It's no fairy tale, but it's turning into a horror story even now. Fourteen years ago, a 14-acre piece of land became the property of the City of Los Angeles under the laws of eminent domain. Landowners were compensated, and the city planned to build an incinerator on the site. Because of complaints of people in the surrounding neighborhood, the city abandoned the plan. However, if within 10 years the city determined that it no longer needed the land, the former owner, a large investment firm, was granted rights of first refusal. The city then set the land aside for a community garden, allowing the Los Angeles Regional Food Bank to manage it.

The garden has been a tremendous success. People from the neighborhood have been growing masses of food from the reclaimed land, which they use to reduce the cost of their own groceries, as well as helping others. The garden has become a community center, with special events, fairs, and a Farmer's Market.

But behind the scenes, the city was busy negotiating with another investment firm to sell the land. Back and forth negotiations went, with the investment firm at one point raising a lawsuit against the city for demurring on their deal. After several years of negotiating, the city finally settled with the firm and sold the land. Only then did they inform the food bank of the deal, which was the first notice that the gardeners had of their garden's impending doom. At no point was the food bank nor were the gardeners allowed to make an offer of their own. The gardeners banded together and raised a lawsuit of their own against the city for breaking the charter with the food bank, but the city claims it no longer needed the land, and that this loophole in the law took priority over the charter.

This morning, police in riot gear arrived to evict the farmers. Fire trucks were on the scene, ladder trucks to pluck protesters out of trees -- yes, trees, which shows how far this garden has come from the old vacant lot it once was. Trees planted by the gardeners themselves, and bearing fruit.

This evening, the bulldozers arrived. Tomorrow, Los Angeles' own Eden will be a dirty scar.

Cheers, L.A.

The gardeners haven't given up, however, in spite of the imminent destruction of fourteen years worth of hard labor. They're still trying to raise funds to buy the land themselves, and will return all donations if they can't buy the land. Their site is here: South Central Farmers

I am a snapdragon -- Don't ask me why...

...because I really don't know, but the quiz was kind of fun:


I am a
Snapdragon

What Flower
Are You?



And it says: "Mischief is your middle name, but your first is friend. You are quite the prankster that loves to make other people laugh."

Now I'll have to take the quiz again and pretend to be other characters to see what other flowers people can "be."

Stepping Stone Project: Complete

At last, the concrete stones from my first major concrete poetry project (besides the single stone that said "welcome") have been poured, the letters pressed into them, and the lot have been allowed to cure for a while. They should probably cure another week before anyone walks on them, but I was ready to get them off of the back deck, so I laid them out on the newly renovated bed under the crabapple tree. I don't expect anyone to go traipsing across them there, so they should be fine. You can't really tell in the picture, but the five of them spell out "grow where you are planted." A nice sentiment for all of us -- and perhaps a command to my new transplants? "Grow! Yes, grow! Don't die! Grow!"

A couple of closeups show the lettering and decorations a bit better. Here's "grow where you":


And here's "are planted":


The marble decorations came from the floral aisle in the craft store. I used opaque glass rather than the transparent glass, because I thought it would look better in concrete for this project. Either would have been fine. Transparent deep colors would look more jewel-like.

And some more pictures from around the garden, since I had the camera out.

The nuthatches are working on a second brood in the nesting box in the front yard. They finished one brood late in April. I caught one of them bringing food to the current set of nestlings:


A clump of bright pink dianthus that's just come into bloom. I'd forgotten I'd planted it!

One of the pink petunias that I grew from seed that I got from Thompson and Morgan:


And a look up into the crabapple tree, where the Lincoln Constance rose is busy blooming away, scattering rose petals far and wide:

Long-legged Rats: Deer in Suburbia

"They're nothing but long-legged rats!" a gardener friend once said. They dine on expensive hybrid roses. They take a bite out of each of the melons on the vine, spoiling all before they move on. They'll yank the broccoli and lettuce out of the ground, and make short work of the perennial bed.

They're Bambis in Suburbia, Over the Hedge in 3-D real life, and not nearly so funny when they gobble up the plants that you've poured money and sweat into.

Within a half mile of our house is an abandoned orchard where the deer roam, and sometimes wander out into the surrounding neighborhoods. Recently the bulldozers have been at work, since someone plans to subdivide and build on the site (exactly who we don't know, nor do we know what the plans are, as they seem to change as often as Madonna's new "look"), pushing the deer out of their former home. They haven't turned up in our yard yet, but as there is an overgrown wood nearby, and a convenient back alley access, it's only a matter of time. Others in the neighborhood have not been so fortunate. Their excitement about the ooh-so-cute brown-eyed delicate-looking creatures quickly turns to rage as Bambi bites all the flowers off of the tea rose.

Why do they do it? Why do the take a bite here, a bite there, and ruin all the pumpkins or melons in the patch instead of feeding on just one? Because they're browsers, not grazers. It's the way that deer eat. They're also edge species, moving from wood to meadow and back again, and when we carve up the woods to make suburbs, we provide more edges than nature ever intended, increasing their habitat many times over. They we lay out a banquet of roses and veggies for them. What else are they going to do but belly up to the buffet and sample everything, then trot off to the woods to make more little deer?

When I was a kid, though, I grew up in the country, where deer made regular treks across the front lawn and through the garden. We tried all the "sure-fire" remedies that we'd heard recommended. We hung aluminum pie tins out where they'd rattle in the breezes. It helped a bit with the birds, but the deer were unfazed. We hung strong-smelling soap -- Lifebuoy was the supposed magic brand -- but it had so little effect, we half-suspected the deer were showering with it. We scattered human hair around, but the deer seemed so used to the presence of humans already that this barely registered with them. We tried sprinkling blood meal around. Great fertilizer, lousy deer repellant. The only "deer-proof" plants that were ever actually deer proof seemed to be the daffodils. The rest were fair game, even if they were only second choice, and the only thing left during the dry season of August and September.

Besides, by the time you apply all the usual remedies, and reapply them frequently, you'll spend all of your gardening time hanging up noisemakers and applying noxious mixtures. Who wants a smelly, noisy garden anyway?

The only thing that ever worked were physical barriers. A simple fence made of metal stakes with twine slowed them down a bit, at least in the raised bed in the turnaround where the roses were. Late in the summer when everything dried up, they'd still manage to hop over this. The electric fence that Dad strung around the vegetable garden did a better job, as did the wire mesh cages -- simple cylinders of hardware cloth -- that went up around the blueberry bushes. And a taller, more permanent fence that he built around the permanent garden, where the berries and grapes were, managed to protect those plantings reasonably well.

I think it's a cycle that all gardeners go through. First you try what amounts to little folk charms because someone swears they'll work and they're cheap -- cheap that is until you lose that expensive perennial that you've been nursing along. Eventually you realize that "cheap" means spending the money to do things right in the first place. Up goes the fence, and the deer move on.

Since the configuration of our yard doesn't make it easy to fence, I'm hoping that the deer never discover us. But if they do -- well, I'd better start setting something aside against that day, because fencing everything in isn't going to be cheap. Either that, or build wire mesh covers, though I don't fancy keeping a cage farm.

The Washington Post has more on the subject, here: Not Yours to Munch, Deer.

Save Gas -- Grow Food

Every couple of years our family takes a road trip back to Indiana to see my mother-in-law. We often get off the freeway and see the sights, or just enjoy the scenery as we go.

As a gardener, of course I'm interested in what other people have in their gardens. One thing that has often struck me as we pass through ranch country and then Midwest farm country is the decided lack of visible vegetable gardens.

Maybe it's just the areas we pass through. Or maybe the farmers and ranchers are incredibly busy people. Or maybe it's an unfortunate trend. But when I see a house sitting in the middle of the sagebrush with nothing around it but a patch of lawn and no hint anywhere of food growing up around it, I have to wonder why. Is it really cost-effective to drive all the way to the nearest store, which looks to be an hour or so away at least, to get everything that the ranchers and their help eat? Having not been raised on a South Dakota ranch, I'm in no position to make a definitive statement on that. But I have to wonder, especially now with rising gas prices.

My grandmother spent part of her formative years on a potato farm in the bustling town of Tule Lake, California (just across the Oregon border from Klamath Falls). She grew up with gardening as a part of her life, and every year up until her 90's, she planted a vegetable garden. My parents grew up with victory gardens, during the war years when growing and preserving food was a patriotic act. When I was a kid, my parents grew and preserved corn, tomatoes, blueberries, raspberries, and lots of other produce, and we went to orchards to pick fruit for canning. This was such an integral part of my life that it seemed odd to me as I grew up to find that there were other people in the world who didn't grow so much as a parsley sprig or a strawberry that's worth eating.

We've gotten so used to perfect produce shipped from thousands of miles away that it no longer seems strange to see seasonal produce in the supermarkets all year long. But as gas prices continue to skyrocket, transportation costs for imported produce are increasing, which means the cost of the produce will increase along with it.

But it doesn't take a lot of gas and money to put fresh produce on our tables, not for people who have even a small patch of sunny earth to call their own. Along with other gardeners, I'm wondering if increases in fuel prices and resulting increases in food costs will spur a new gardening revival. So long as people are sensible about their gardening practices, and don't go to the extremes described in The $64 Tomato, growing some of your own food can help offset the rising grocery bill.

If you don't have a suitable spot for a vegetable patch, or don't have the time for a vegetable garden, buying locally-grown produce is a great alternative. Check out the 100 mile diet site, a terrific resource for people who want to buy their food from local growers and producers. The idea is to buy food that is grown within 100 miles of your home. That may sound like a long distance, but it's a whole lot better than the of 1,500 miles that the average food item travels from farm to plate -- and produce imported in the winter travels a whole lot farther than that.

How easy it is to go on the 100 mile diet may depend on where people live. Where I live there are lots of fruit farms and a handful of independent meat markets, as well as lots of fruit stands. It's not hard to find peaches, pears, cherries, blueberries, and other fruit for freezing and canning, and locally-grown meats at reasonable prices. Big cities often have farmer's markets where city folk can find farm-fresh produce. But while my mother-in-law can buy fresh corn in season in her area of Indiana, fruit farms are far scarcer than they are where I live.

If we all do what we can -- grow what we can, and buy what we can locally -- we can all make a contribution to fuel conservation.
