Tips For Starting Your First Backyard Garden


If you're new to backyard gardening and want to start growing vegetables, 

    here are some tips:
 
Location, location, location: Give the garden a sunny spot. Pick a garden location that gets at least six hours a day of full sun. Good drainage is key. That's why raised beds are so popular (that, and the soil in raised beds warms up sooner in the spring). Make sure a source of water is nearby. And, a location that is easily seen on a regular basis from a house window (esp. the kitchen), is a good reminder of what's out there and what needs to be done.

 
Know your soil. Do a pH test (which measures the relative alkalinity or acidity of the soil), or a full soil test. One of the best bargains for a complete soil test is the University of Massachusetts. They will analyze your soil for under $20 (at this writing). They also include an interpretation of what all those measurements mean to you.



• Amending the soil with a good quality compost is a great idea, if your soil has never been amended. Rototill in a cubic yard of compost for every 300 square feet of garden. That is a rule of thumb that I follow. After the first growing year, no rototilling is necessary. Just add a few inches of compost to the top of the soil; let the winter rains work the compost in.

• Fertilize the soil. I prefer to use low-dosage organic fertilizers, such as a mix of fish emulsion and sea kelp. There are plenty of great all-in-one organic fertilizers on the market labeled for use in vegetable gardens. Be sure to follow the label directions. If using a non-organic granular fertilizer (such as a 10-10-10- formulation), put a tablespoon in the bottom of the planting hole, cover with a couple inches of soil, and water in thoroughly. Don't let the sensitive roots of the tomatoes and peppers come in direct contact with the fertilizer. If you'll be using a water soluble, non-organic fertilizer on an every-other-week or monthly basis, use half the recommended amount for this first feeding.

Good sources of information:



The UC Davis Vegetable Research and Information Center is a good website with more garden starting info.

For California gardeners, the Farmer Fred interactive Vegetable Planting Calendar is a good guideline for when to plant. Also, clicking on the individual vegetables brings up information on how to grow it.

That's the basics! What you plant is up to you and your family's appetites. 

Read on for more detailed gardening information for the first timer:


Peppers spaced 2 feet apart. They WILL fill the bed! Trust me on that.
For tomatoes and peppers:

• Plant tomatoes deeply. Pinch off the lower leaves of the plant and bury the tomato deeply, leaving only the top four sets of leaves above ground. New roots will form along this underground, stripped section. If it's a very tall plant, dig a trench, lay the plant on its side in the trench, and bend the top section up (carefully) to stand above the soil level; fill in the trench.

Tomatoes spaced three feet apart. They also WILL FILL THE BED.


  • Give tomatoes room. Full-size tomatoes grow on vines that can reach five feet high or more. Plant them three to four feet apart. Prepare a staking system now while they're still manageable.

  • Plant peppers no deeper than the soil level of the pot it came in. Peppers can be spaced two feet apart.



 
Water. Don't let the soil dry out while the roots are getting established. During the warmth of summer, water tomatoes and peppers regularly, keeping the soil evenly moist. One common problem with tomatoes, blossom end rot (the bottom of the tomato turns brown and mushy), can be traced in part to irregular watering habits. Deep, infrequent waterings (once or twice a week) with drip irrigation or soaker hoses work great. An added benefit: drip systems and soaker hoses can be hooked up to a battery operated timer, watering these summertime treats while you're vacationing.
When deciding where to plant your vegetable garden, choose the best available location by keeping the following factors in mind:

When is the soil ready to plant? You may have little choice concerning the soil type available to you, but you can use a simple test to find out whether your soil is in good condition for planting. Squeeze a handful of soil to test for moisture content. If the squeezed soil forms a clump, the soil is too wet to work. If you work soil that contains this much moisture, it might form into hard, cement-like clumps, which can cause problems for the remainder of the year. If the soil crumbles easily when it is squeezed, it is in an ideal condition to work. However, if that handful of soil is bone dry, water the area thoroughly a day or two before working or planting the soil.



Broccoli in the Winter Garden
 The Year-Round Garden. In California, there are 3 to 4 seasons, depending on your location, in which vegetables can be grown. Yet, many gardeners grow only summer crops. By planting a spring crop, a summer crop, and a fall crop, a gardener can get 3 crops from the same space.

 

Level ground is best for growing vegetables. It is easier to prepare, plant, and irrigate than sloping ground. If you must plant on sloping ground, run rows across the slope, not up and down, to keep the soil from washing away during irrigation.





Preparing a Garden Plan
It is best to plan on paper before planting your garden. A well-planned garden can provide fresh or preserved vegetables for use all year.  










Plant perennial crops, such as rhubarb and asparagus, to one side of the garden so that the plants are not disturbed by preparations for future crops. Plant tall crops, such as corn and pole beans, on the north side of the garden so that they will not shade low-growing crops.




Trellising and staking. Do not grow horizontally what you can grow vertically. Twining crops, such as tomato, squash, cucumber, and pole beans, use a great deal of space when allowed to grow along the ground. Trellises, stakes, or other supports minimize the ground space used and increase garden productivity. Support materials can consist of wood, extra stakes, twine, or a nearby fence.

 



For the beginning vegetable gardener, choose more hybrid seeds than heirlooms. Hybrid vegetables are bred to have more disease and pest resistance, as well as larger yields. Heirloom varieties have more unique shapes and flavors, but can be problematic for the first time gardener. Sure, buy some heirlooms for the flavor; but for your first garden, plant mostly hybrids. After that, you may prefer the flavor of the heirlooms. I still plant a mix of both.

Succession planting consists of sowing seeds of a given crop at 1- to 2-week intervals to produce a continuous supply of vegetables. Corn, beans, lettuce, turnips, and beets are well suited to this practice.

Intercropping involves planting early-maturing crops between the rows of late-maturing crops to increase production in a small area. For example, beans, radishes, green onions, spinach, or leaf lettuce may be planted between rows of tomatoes, peppers, cabbage, or corn. The quicker-maturing crops will be harvested before the others become very large.



What to Plant
Plant enough of each vegetable crop to meet your family's needs for fresh, stored, and preserved supplies. When choosing vegetable varieties or hybrids, consider such factors as disease resistance, maturity date, compactness of plant, and the size, shape, and color of the vegetable desired. Refer to the individual vegetable links on the Farmer Fred Interactive Vegetable Planting Calendar for variety recommendations.




Tools
You only need a few, good quality tools for a small home garden:


Trowel. One of the handiest garden gadgets, it is useful for transplanting and for loosening soil around plants.

Shovel. Use a round-edged shovel for digging.
  
Spade or spading fork. Use to turn the ground, to turn under organic matter, and to break up large clumps of soil.



Rake. Use to smooth out the soil after spading and after preparing the seedbed. You can also use it for clearing up rubbish and removing small weeds.

Hoe. Use to remove tough weeds and to cover seeds after planting. When turned sideways, you can also use a hoe to dig a V-shaped row for planting.



Following these simple guidelines will keep your tools in good condition:


Clean tools after each use. A putty knife, jet nozzle on a hose or a wire brush is good for scraping off dirt. If tools get rusty, soak them in kerosene for a few hours, then use a wire brush or fine sand to scrub off the rust. Oil them with a light lubricant after cleaning.


Keep cutting tools sharp. The basic sharpening tool for hoes, pruners and shovels is an 8" mill file.
 

Keep tools in a dry place to prevent rust.

Heirloom Vegetables Are Better For You

Awhile back, we wrote about the nutritional benefits of growing heirloom tomatoes, citing a study from the University of Texas, showing that supermarket tomatoes have dropped in nutritional value since 1950. 

“We conclude that the most likely explanation was changes in cultivated varieties used today compared to 50 years ago,” Dr. Donald Davis, the leader of that study reported. “During those 50 years, there have been intensive efforts to breed new varieties that have greater yield, or resistance to pests, or adaptability to different climates. But the dominant effort is for higher yields. Emerging evidence suggests that when you select for yield, crops grow bigger and faster, but they don’t necessarily have the ability to make or uptake nutrients at the same, faster rate.”
 
That report from the University of Texas also showed a precipitous drop in the nutritional value of other vegetables. The full study printed in the December 2004 issue of the "Journal of the American College of Nutrition" says that hybrid varieties of fall/winter garden favorites such as broccoli (vegetable #5 in Table 2 of that study), cabbage (#7), cauliflower (#11), chard (#13), kale (#20), lettuce (#22), peas (#28) and spinach (#35) have current nutritional shortcomings, compared to 50 years ago. 

The study compared calories, protein, carbohydrates, calcium, phosphorus, iron, Vitamin A, Thiamin, Riboflavin, Niacin, Ascorbic Acid and other nutrients. In just about every case, the 1950's version of supermarket veggies was better for you than the 1999 selection.

Using broccoli as an example, the 1950 crop had nutritional advantages over the 1999 broccoli in the following categories (measured in grams or milligrams, unless stated otherwise) per 100 grams of edible portion:

Protein: 3.3 (1950) to 2.9 (1999)
Carbohydrates: 5.5 to 5.2
Calcium: 130 to 48
Phosphorus: 76 to 66
Iron: 1.3 to .88
Vitamin A (IU): 3500 to 1542
Thiamin: .1 to .06
Riboflavin: .2 to .1
Niacin: 1.1 to .6
Ascorbic Acid: 118 to 93

What else is different between supermarket vegetables grown in 1950 and vegetables grown today, besides the introduction of nutrient-sapping hybrid varieties?

The farm itself and the methods used to grow the food, including the increasing use of inorganic chemical fertilizers and pesticides to increase yields.

As a youth, I spent summers at the family farm outside Wibaux, Montana. Grandpa, Grandma and Uncle Hubert ran the "operation" (which was comprised of Hubert's two children, his wife Minnie, and cousin Gary). Fertilizer for the vegetables grown there came out of the back end of horses, cows, sheep and pigs. "Use every part of the pig except the oink," Uncle Hubert was fond of saying. 

Seeds were saved at the end of each growing season from the current year's crop. The family was too poor to afford expensive pesticides, so Grandma headed out to the vegetables each morning to spray the aphids off with water from the hoses that ringed the acreage. 

They were organic, or nearly organic, out of necessity. Several times each week, Hubert would truck the vegetables into town to the local market.

Now, that 160-acre farm is out of the family's hands and has been combined with several other local farms and is run by a conglomerate.

Bottom line: if you want to feed your family the most nutritious (and safe) vegetables, grow them yourself, using heirloom varieties and growing them as organically as possible. 

Second best option: buy your vegetables at a farmer's market. Here in Northern California, there is no shortage of farmer's markets, nor a shortage of farmers selling organically produced heirloom vegetables.

Among the online seed catalogs specializing in heirloom vegetable seeds:

There are plenty more sources for heirloom seeds. Mention your favorite!

How Long To Run a Drip Irrigation System?


     90% of all plant problems are water related, either too much or too little. Compounding the problem: gardeners who are operating a drip irrigation system but using a sprinkler mentality.

     Callers to the radio show, after describing a plant problem will be asked: "How are you watering that plant?" More often than not, if the answer is, "drip irrigation", they will follow that with, "And I run it for five minutes a day, everyday."
And therein lies the problem.

     A drip irrigation system puts out water much slower than a sprinkler system, usually a gallon or two an hour versus a sprinkler system's output of a gallon or two A MINUTE.

     In five minutes, a 1 gallon per hour (gph) drip emitter will put out about 10 ounces of water...slightly more than a cupful. Not only will that pittance of water not saturate the width of the plant's root zone (which can extend beyond the canopy of the plant), it won't penetrate more than an inch or two. And then not stay there very long.

     What happens to a plant with a shallow watering program? The roots stay very near the surface, where they are more subject to drying out quickly. This boom and bust cycle stresses the plant, opening up the possibility of disease and insect invasions.

     With a drip irrigation system, don't think "minutes". Think: "hours". And water deeply, but infrequently (once or twice a week).  

Your goal is to apply enough water to penetrate the soil to a depth of at least 8 inches, preferably more. The day after you water, either dig down 8 inches by hand or with a soil sampling tube; or, stick a moisture meter down to that depth to determine if the soil is moist (not dry, and not soggy). Battery-operated soil moisture meters (such as the yellow one, pictured on the right) tend to have a longer life.

In our raised bed vegetable garden, the summer watering regimen is with an inline drip irrigation system (1 gph emitters along the line, spaced 12" apart) which is run twice a week, six hours at a time. Your weather, soil type, slope and crops may need a slightly different watering schedule. In our 4'x20' raised beds, three inline emitter lines run the length of each bed. The lines are spaced 12" apart.

Consider using microsprinklers or sprayers to thoroughly wet the root area for trees and shrubs. These put out more water, usually between 8 and 20 gallons per hour. We have these on our shrubs and fruit trees, and during the summer will run them for about an hour, once or twice a week, depending on how hot it is.

     The other part of the drip irrigation equation that a lot of gardeners miss: not enough emitters for the plant. Placing one emitter next to a new tree or shrub is not enough. Remember, plant roots tend to grow out horizontally. Emitters should be spaced evenly around the tree or shrub, in a circle, halfway between the trunk and the outer canopy of the newly installed plant. The spacing between the emitters will depend on your soil type: for sandy soils, use a 12" spacing; for heavy clay, 18-24" spacing. Add emitters towards the outer canopy of the plant as the plant grows.
  

• Soaker hoses need maintenance, too. Flush them monthly. The Dramm soaker hose, pictured here, is the most reliable, even-flowing soaker hose I have ever used.

 





A great online tutorial of drip irrigation: the Dripworks website. This site has helpful tips and videos that can help beginner and pro alike solve their drip irrigation and yard watering woes.

     The Dripworks catalog is also great resource for anyone tackling the problems associated with drip irritation...uh, irrigation. Just thumbing through the catalog can give you several "Aha!" moments for improving your own yard watering procedures, especially if you are looking to replace your residential sprinkler systems with a drip irrigation system, which can work with your existing automatic sprinkler system control box.
