Aquaponics

Ok, so most of us have seen the aquaponics project at Epcot.  Everytime I see it, I commit to starting a small tank of my own when I return home, but then I never get around to it.  Guess what?  I'm finally going to do it.

Aquaponics is an integrated system with fish and plants.  The fish provide nutrients for the plants.  The plants return the favor by filtering the water for the fish.  Shouldn't all life be so in sync?

Ok, so the system is slightly more complicated than this, but is certainly do-able for home gardeners & fish lovers.

This blog will be short on details because I'm still learning.  I'll get more specific in later blogs.

We're going to start with four 55 gallon food grade plastic barrels.  (Stay away from chemical laden black barrels.  The red and blue barrels are usually food grade.) 

Basically, we'll cut out the sides of two barrels and lay them horizontally on my plant stand.  I'll fill these with gravel and plant lettuce starts in these planters.  On the patio next to my plant stand, I'll set up a barrel, vertically, for the tilapia.  We chose tilapia because they withstand our Florida weather conditions nicely.  The tilapia barrel will contain an aquarium pump and aerator. 

Water from the tilapia barrel will pump into a barrel of gravel and red worms.  The gravel will filter out large sediment from the fish waste and the worms will feed on this waste.  Once again, WORMS RULE!!   During this stage, nitrites from the fish are converted by bacteria to nitrogen (plant food!)

From the worm/gravel barrel, the nitrogen rich water will flow into the planters.  The plants will filter the water before it flows back into the fish tank.

If any of my readers have an aquaponics system, I hope you'll answer the following questions for me:

-How is the composted material from the red worms harvested? Or does this just flow into the planters?  If so, wouldn't the worm castings clog the tubing as much as the fish waste?

-What is the most humane method of harvesting the fish?  Call me a weenie, but I just don't like killing animals.

So that's my big project for August.  I bet I'm not the only person who likes working on new projects...keeps life interesting!

Create a Living Wreath Made of Herbs for Holiday Meals

Living wreaths add beauty and fragrance to your home during the holidays. Harvest sprigs from the wreath to flavor your holiday meals.

To make a holiday wreath, begin with a metal wreath form. Wrap it in moistened sphagnum peat moss. Tuck 3"-5" herb plants into the wreath and secure with florist pins. Wrap with additional moss to hide roots.

Prepare a tray (large enough to hold the wreath) with a thin layer of soil over a 2" layer of moistened gravel. Lay the wreath flat on the tray in a sunny area. As the herbs grow, continue to secure them to the wreath. In about 4 weeks, your wreath will be sufficiently full to hang from a doorway. Take the wreath down after the big day and return it to the tray when the guests have gone home.

Herbs to grow for the holidays:

Creeping Thyme -- Excellent on everything from Turkey to roasted vegetables.
Rosemary -- Delicious on lamb, pork tenderloin, red meats, and vegetables.
Sage -- A must for traditional turkey and dressing.
Parsley -- Not just a garnish! I prefer the flavor of the flat leafed Italian
variety over curly parsley. Used in many sauce recipes, salads, and other vegetable dishes. Add finely chopped parsley and chives to green beans.
Tarragon -- Integral in French cuisine, Tarragon has a strong, slight licorice flavor. It's often used in butter base sauces and included in a rub for Turkey and Lamb.
Chives -- I love finely chopped chives in my mashed potatoes. They are also commonly used in vegetable dishes.
Mint -- Removes the gamey flavor from lamb.


Happy Holidays

Understanding the "Dirty Dozen"

Excerpt from "Container Gardening for Health: The 12 Most Important Fruits and Vegetables for Your Organic Garden" ISBN: 0978629329.
...In 1988, The National Research Council was commissioned by the U.S. Con-
gress to study issues concerning pesticides in the diets of infants and children using USDA/FDA data .
The results of this study are published in a 372 page book, Pesticides in the Diets
of Infants and Children(ISBN:0309048753).  The study concludes that children are uniquely suscep-
tible to health problems from exposure to toxic pesticides because of their rapid
growth. Infants and children also consume greater quantities of certain foods as
a proportion of body weight. This leads to greater exposure to some pesticides.4
The problem with pesticides is that the quantity of a vegetable your child eats
may exceed government expectations. Anyone who has children knows they go
through phases where they will only eat one food or one group of foods. Since the
government is not in your dining room calculating how many pounds of straw-
berries your tot has eaten this week, they cannot tell you if she has consumed
too much of a certain pesticide. The government can tell you what foods have
chemical residue even after they have been washed and prepared for eating. In
fact, the U.S. Department of Agriculture and the US Food and Drug Adminis-
tration conducted nearly 43,000 tests on produce samples from 2000–2004.
The Environmental Working Group (www.ewg.org) analyzed this data and created a “simula-
tion of thousands of consumers eating high and low pesticide diets...” Their study
showed “that people can lower their pesticide exposure by almost 90 percent by
avoiding the top twelve most contaminated fruits and vegetables and eating the
least contaminated instead.”5 They nicknamed this list of foods “the dirty dozen.”
As of June 2007, the dirty dozen is as follows:
Rank Fruit or Veggie Score Page number
in this book
1 Peaches
2 Apples
3 Sweet Bell Peppers
4 Celery
5 Nectarines
6 Strawberries
7 Cherries
8 Lettuce
9 Grapes, Imported
10 Pears
11 Spinach
12 Potatoes
The list has changed slightly since this book was published -- Kale has moved to the top 12 and spinach has moved down slightly, but all the fruits and vegetables above still remain high on the list.
At The Gourmet Gardener, we don't believe you should have to limit these healthy fruits and vegetables in your diets. Instead, select foods your family commonly eats on the Dirty Dozen list and grow them organically. Use this book as a guide to growing healthy fruits and vegetables in containers and small spaces.

Fall & Holiday Gardens

North Florida has two main growing seasons: spring and fall. I prefer fall. By late September, we are usually coming out of the hurricane season with a replenished water table. Additionally, cooler temperatures discourage pests and weeds. Often, our winters are so mild we can extend the fall garden right through Christmas. I am not exaggerating when I say I often pick Arugula for our Christmas salad.
It's time to prepare now for a fall garden. Plan where you will grow your crops, taking into consideration their light, moisture, space, and temperature requirements. If you will need to bring the plants inside during cold snaps, make sure to plant in light weight containers and include soil components such as vermiculite and perlite.
Many seeds prefer warmer temperatures for germinating than for growing. You can start seeds in late August and have them ready to produce fruit by October.
Also, don't forget to think about your holiday menu when planning a fall garden. Grow fresh sage and tarragon for your turkey, baby carrots, and a myriad of lettuce greens for your salad. Start in August!

Organic Vegetable Gardening in Containers

This blog is an effort to get more people gardening organically. I think there is a misconception that gardening is expensive. When comparing the price of organics at the store to home grown organics, you'll see that growing your own is not only healthier, but also less expensive.

For my garden this year, I spent about the equivalent of one week's grocery bill for my family of four. For that price, I now have cherry, apple, nectarine, and pear fruit trees that should produce for years to come; I also have strawberry plants, sweet bell peppers, tomatoes, grape vines, lettuce and spinach seeds, and potatoes. In my next blog, I'll talk about food safety.

I'm growing the above mentioned plants because they are the plants with the highest pesticide residue according to USDA data. I researched this so much that I eventually wrote a book about it --
