A plant’s main enemies are pests (such as rabbits, insects, slugs and snails, and nematodes) and diseases (like fungi, bacteria, and virus). Most can be controlled using ecologically friendly methods. Rather than setting a goal of a pest-free garden, learn how to work with nature to keep problems at an acceptable level. Vigilance is the key to growing good plants; paying close attention to how the plants are growing will pay off. Finding a pest or disease problem in the early stages, when it is relatively easy to deal with, is preferable to suddenly discovering that the crop or plant in question is seriously infected with some problem.

Pest control This can be approached in stages, depending on the problem. Animals (rabbits, gophers, etc.) can be kept away from food crops by surrounding the area with a wire fence with the base buried in the soil. In the flower garden, plant species they do not like to eat. Protect the stems of trees with a wire guard for the winter (make it high enough to allow for snow) and spray shrub stems with a hot pepper spray after the last rain in fall. Deer and elk are difficult to repel without enclosing the entire garden with a high fence, but there are plants that they are less likely to eat (see list on p. 68).

Large insects, such as caterpillars and beetles, can be picked off by hand and dropped into a bucket of soapy water. When larger plants, like trees, are attacked, the soil directly under their foliage can be covered with drop sheets and the plant shaken to dislodge the pests. The drop sheets can then be carefully lifted and the pests destroyed. Caterpillars that congregate in webbing “nests,” like tent caterpillars and fall webworms, should be controlled during the day, when the young larvae have left the nest, by spraying them with Bacillus thuringiensis. Another alternative is to wait until evening when the caterpillars have returned to the nest. Prune off the nests and immerse them in a bucket of soapy water to kill the larvae.

Plants can be protected from damage by soil-dwelling caterpillars, like cutworms, by enclosing them in a barrier made from half a frozen juice can or a circle of heavy-grade tinfoil pushed slightly into the soil. Wireworms (orange and curl into a half circle) and millipedes (dark brown and curl into a spiral) both live in the soil and feed on plant roots or burrow into root crops. They are seldom numerous, except in reclaimed pastureland, but destroy them when digging.

Quick-moving small pests, such as <!–more-memberlock–>flea beetles, carrot flies, and leafhoppers, can be kept away from young plants — the most vulnerable — by covering them with a floating row cover supported on wire hoops made from cut-down clothes hangers. This also gives protection against late frost and against sunscald on newly planted plants.

Slow-moving small pests, like aphids and mites, can be washed off many plants with a strong stream of water, however, this should not be used on plants with large, soft foliage, or on the fragile growing tips of plants. Mites can also be kept to a minimum by spraying frequently with water, using a hand sprayer, and soaking the undersides of the foliage. Planting flowers that attract native predators also helps to control aphids and mites.

Insects can be lured to bright yellow or red traps coated with a nondrying sticky substance, which holds them. There are also traps baited with scent lures called pheromones. These are scents released by insects to attract others of their species. When used in a trap, they may imitate a female scent and entice many of the males to enter. The unbalanced population results in a large reduction in the number of eggs laid, and young hatching.

Many natural predators can be used to help solve a pest problem. They can be released into the garden and will target a specific pest or range of pests (see p. 546). Naturally, it takes time for the predator population to build up sufficiently to bring the problem under control, so there is always a lag between introducing the predator and solving the problem. They rarely completely kill off all the problem pests, but they will bring the population down to acceptable levels. Remember, spraying for pest control will often wipe out the beneficial insects as well.

Nematodes are microscopic wormlike creatures, some of which attack plants, but others are beneficial and attack plant pests. They are especially useful for controlling some lawn pests and are simply mixed with water and applied with a watering can. In warmer parts of the country, one application will give several years control, but in the North, the cold kills them and they need to be reapplied if the problem occurs again.

Bacteria are also weapons in the fight against plant pests. Bacillus thuringiensis kurstaki, commonly known as BT or Dipel, was the original strain that attacks the caterpillars of certain species of moths and butterflies. There are now several other strains of this bacteria that can control Japanese beetle larvae, mosquito larvae, Colorado beetle larvae, and more. A large range of these predators and lures are available by mail or through your local nursery.

If none of the above methods control the problem to your satisfaction, you may have to resort to spraying with one of the organic controls listed on pp. 544–545.

Disease control. This is more difficult than pest control because the disease has usually got a hold on the plant before any symptoms appear. Many fungal diseases are spread by very small spores that float on the breeze and land on a plant leaf. They “germinate” and insert a small thread (called a hyphae) into the plant tissue. This feeds on the plant and grows, forming a network of hyphae between the cells inside the leaf. It is not until this point that the plant begins to show signs of stress — different colored spots, wilting, or fungal tissue visible (as in mildew). Such leaves should be picked off as soon as noticed and put in the garbage — not in the compost. If caught in time, this may be enough to stop the further spread of the disease.

Many plants, providing they are not under stress from poor growing conditions, can emit defensive secretions that can either kill fungal spores or limit the damage they can cause. It therefore makes sense to grow plants properly, giving them the soil conditions, acidity or alkalinity, and moisture they grow best in. In addition, allow good air circulation through plants, especially those, like phlox and bergamot, that are prone to mildew. Stagnant air in the middle of a large clump of stems is a mildew heaven.

Other fungi are great opportunists. Although they are not able to directly infect a plant, they can gain entry through stem and leaf wounds. Many cankers fall into this category. They can attack a plant only when it has been damaged by careless hoeing or gain entry through a wound caused by mower damage.

Fungi are important agents in plant decay, and most work in the gardener’s favor. They help break down compost and are responsible for rotting wood in forests and returning the nutrients to the soil. Without them, the woods would be choked with dead trees. Some, such as coral spot, will also attack living material that is under stress from another cause. The appearance of small, bright coral-pink fungi on a branch indicates a problem.
Most of the fungicides listed in the chart on pp. 544–545 are preventative, rather than curative. They should be applied before the disease strikes to form a protective layer on the foliage that kills the fungal spores on contact.

Bacteria are minute organisms that can be rod-shaped, spherical, or spiral, and there are several million in a typical teaspoon of soil. They are important in breaking down dead plant material, but a few attack living plants, generally causing plant tissue to disintegrate. Soft rot of iris is a typical bacterial disease. They are difficult to control and long-lived in the soil, but generally specific to one species or group of plants. Avoid replanting the same species in soil where a bacterial disease has been diagnosed. Some bacteria attack certain insects and are used as insecticides.

Virus are submicroscopic primitive life-forms that live inside cells of plants and animals. They tend to be very specific, limiting their attack to a single genus or plant family. Some virus are used as insecticides but others attack plants. There is no cure and infected plants should be dug up and disposed of in the garbage. Infected plants usually have foliage with strange mottling or streaks, and are often puckering as well. The recently discovered virus attacking hostas is typical in this way. Plant infections can be spread by hand, shears, and other gardening tools. Newly infected plants may take several years to show symptoms, during which time the virus can be spread to other plants. Virus are also spread by sapsucking insects, such as leafhoppers, so controlling these insects is very important. Many modern varieties of vegetables, especially tomatoes, have built-in resistance to some of the virus and other diseases that attack them. This information is usually indicated by a series of code letters in seed catalogs.

Compost Tea

Homemade compost or special compost preparations available from garden suppliers are the basis of this tea. Simply put a shovelful of finished compost in a burlap sack and immerse it in a bucket of water for about a week. Strain the resulting tea through cheesecloth or some other material to remove all solids. Use the tea full-strength to water any and all plants in your garden. Compost tea not only provides a wide range of nutrients, but it also boosts plants’ natural defenses against disease. Spraying plants with aerated compost tea can convey even greater benefits. To make aerated compost tea, follow the instructions that come with the compost preparations procured from a garden supplier.

Herbal Sprays

While herbal sprays do not appear to actually kill insects, they do seem to act as an effective repellent, and spraying plants with a tea made of garden herbs may help to keep them pest-free. Sage, thyme, rosemary, and white clover seem to help ward off attacks from leaf-eating caterpillars. To make, either soak 1 cup of fresh leaves overnight in 2 cups of water or pour 2 cups of boiling water over 2 cups of fresh leaves. To use, strain, dilute with an equal amount of water, and add a few drops of liquid soap (not detergent) to act as a spreader.

Stinging Nettle Spray

Stinging nettles grow as weeds in the eastern parts of the country but they can be used to make a spray that helps plants resist disease attacks.

When collecting nettles to make the spray, wear long pants, cover the arms, and wear good work gloves. Place about 1 pound of nettle leaves and young stalks in a bag and soak it in 1 gallon of chlorine-free water (tap water that has stood uncovered for 48 hours). Cover the bucket and leave it in a warm place for a week. The mixture will have a strong smell when uncovered and may need straining through a cheesecloth. Dilute with five times its volume of chlorine-free water and spray plants that are known to be susceptible to fungus diseases. Spray every 2 weeks for continued coverage. It also helps deter aphids and acts as a foliar feed. Store any unused spray concentrate in a glass jar, it will keep for a month.

Starch Spray

This forms a sticky coating on the leaf surface, which traps the pests and holds them until they die. It works best on small pests like aphids and thrips, rather than on large beetles and caterpillars. Mix 2-4 tablespoons of potato flour (available in health food stores) in one quart of water and add a few drops of liquid soap as a sticker. Shake well and spray onto the plants, covering the entire leaves. It will wash off in rain or can be hosed off after a few days.

Garlic Oil Spray

A mix of garlic, mineral oil, and soap gives very good results against many sucking and chewing insects. These include aphids, cabbageworms, leafhoppers, larval mosquitoes, squash bugs, and whiteflies.

Some plants are sensitive, so try it on a single shoot first. If there is no damage after 48 hours, spray the entire plant. Soak 3 ounces of finely chopped garlic in 2 teaspoons of mineral oil for 24 hours. Dissolve 1 teaspoon of insecticidal soap in 2 cups of water and add it to the garlic and oil. Stir well and strain. To use, add 1-2 tablespoons to 2 cups of water and spray on the pests. Store the remainder in a glass container for future use.

Hot Pepper Dust

Grow your own hot peppers to provide the source for a repellent dust that will help protect plants from cabbage maggots, carrot root flies, ants, and other pests. Dry the harvested pepper first, and then grind them with a mortar and pestle (always wear protective eye gear and gloves when working with hot peppers because the dust can be very irritating to your eyes). Sprinkle the dust along plant rows just after seeding or around the base of young plants. Apply more dust after rainfall or watering.

The quick and the easy way of clearing the waste from the kitchen and the garden are composting. Preparation of own compost will yield better plant growth in the garden.

For making the garden compost it is a must to have the bin. The bin can be prepared or the same can be purchased. It is not necessary that the bin should be fancy. The purpose has to be served and hence it can be of any shape. But the compost can be well prepared if the bin is of the size of 5 feet wide and 4 feet depth.

It is always better to keep the compost bin in a location that is <!–more-memberlock–>handy and hence will not be necessary to walk several times to reach it. The compost bin has to be kept in a place of sunshine or otherwise a thermometer has to be purchased to measure the temperature of the compost bin. 1400 degree temperature has to be maintained for the compost bin.

A lump of dirt has to be piled up near the compost bin so that the same can be used whenever required for putting inside the compost bin.

A foundation has to be laid on the compost bin which can be made with 12” of grass clippings or even with the leaves of dead yard to the extent of 2 feet.

The waste from the kitchen and the garden like egg shells, coffee grounds, potato skins, tea bags, vegetables and fruits has to be accumulated in the bin. Greasy products and the meat should not be added into the compost bin.

When sufficient quantity of the waste from the kitchen and the garden is gathered over the foundation on the compost bin, then it is time to add the fertilizer, garden soil and half cup of limestone to this mixture.

Now the compost bin will be with the layers of foundation, waste from the kitchen and the garden, fertilizers, limestone and the garden soil. At this juncture, the compost pile has to be watered and moist temperature has to be maintained.

At last, the compost pile has to be turned which is a very important process. The turning of the compost pile should be done with a time gap of 15 days. Due to the rotation, bad organisms and the weeds that sprout in the compost pile will be killed. Thus the heat speeds up the process of decaying.

The process of adding up the waste from the kitchen and the garden has to be continued. The layer in the compost pile has to be followed. The turning of the pile once in 15 days to get good garden compost has to be done compulsorily. It is important to note that the stems with large diameter should not be put in the compost pile.

One of the best natural solutions to make your plants healthier is through the use of compos tea. Compost tea is the process by which you use compost to brew a liquid solution that you will then “feed” to your plants. Compost tea can be applied to vegetables, trees, bushes, flowers, or in short anything that you grow that you want to get healthier.

The first step is to get compost. You can buy compost from a local nursery or garden center but the better option is to make your own. You make compost from organic material. In other words grass, leaves twigs, and food waste to name a few.

You then take the compost and mix it with water. After about an hour of <!–more-memberlock–>soaking you can use the compost enriched water on your plants and you will get excellent benefits, but if you really want to get the most out of your compost tea, you have to brew it.

To brew compost tea you simply add an air pump to pump in fresh oxygen into the water as well as one to two ounces of molasses. What you are doing is creating an environment where bacteria that live in the compost will thrive.

After brewing for a couple of days separate the compost from the liquid with a strainer such as cheese cloth or an old screen and you are all. Put the liquid in a watering can or sprayer and let your plants have it. It is the most natural type of fertilizer you can ever apply to your plants that no chemical can reproduce.

Compost tea introduces healthy minerals and nutrients into the soil as well as “good” bacteria that work hard in the underlying ecosystem to create an environment for the roots of your plants to thrive.

Compost tea has also shown to prevent many diseases found in plants due to the microbial population found in compost tea.

You should apply compost tea first thing in the morning and if you are putting it directly into the soil it is ok to apply during rainy conditions, however if you are applying it directly to leaves then you should wait for a dryer day.

Studies have shown it is best to use your compost tea within 4 to 6 hours after you brew it. Remember you have living organisms in that tea and having it sit around too long can kill them and render your tea useless. Besides you have been waiting 2 days to use it while it’s been brewing.

As you can see compost tea has many benefits. Whether you are an avid vegetable, flower or shrub gardener, or are new to gardening altogether, then you should get to know how to brew compost tea, and start applying it to your gardens immediately.

The definition of Organic Foods means that these foods are either grown or made per a set of criteria or standards and before they can be called organic they must obtain an organic certification.

In order to achieve the organic certification the foods must void of most synthetic chemical inputs such as fertilizer, pesticides, antibiotics (in regards to live stock), any food additives and so on. The farmland that has produced the food must have been free of any chemical inputs for a minimum of three years. The grower of the food must keep a written detail account of production and sales records. Certified organic products must be kept separated from those products that have not been certified and periodically the site growing the organic food will be inspected.

In some countries certification of organic foods is a strict process overseen by that countries government. But here in the United States the certification can be handled by third party companies whose sole purpose is to certify growers (or manufacturers) of organic products.

Since we are specifically talking about growing foods organically in this article you would fall under the realm of farming. In order to be considered an organic farmer you must study organic standards, make sure the area in which you will be farming the crops is in complete compliance with organic <!–more-memberlock–>standards, obtain an on-site inspection along with passing an oral interview and of course the annual fee to keep the organic certification which can run anywhere from $400 to $2000 depending on the size of the operation. All agencies that hand out that hand the certifications must first be approved by the United States Department of Agriculture.

The term certified organic is protected by legislation here in the United States so that the consumer purchasing a product for the sole purpose of it being organic is kept safe. In other words, it is to prevent manufacturers from misusing the term certified organic to deceive the public.

There are three levels of organic rating in the United States. The top level says that the products have been certified therefore the manufacturer of that product can use the term certified organic. The second level says that the products being manufactured have used at least 95% organic ingredients therefore can put the organic label on their products. The third level of which at least 70% organic ingredients were used can only use the seal “made with organic ingredients”. Anything less than 70% can not use the term organic anywhere on their labeling.

As you can see becoming an organic gardener, a certified one that is, can be a lot of work. However, if you truly believe in going organic and growing your vegetables and fruit in this manner then the work will be well worth it for you.

Vegetable gardeners were going green long before “green” went main stream. We have been recycling food waste for decades, storing up rain water in barrels to use when the weather runs dry and so many other things.

But now that the world has finally caught on with the green movement, it is time to pass along a list of items that many might overlook and consider trash, but really are great to use in the vegetable garden.

Cardboard Egg Cartons
If you buy your eggs in Styrofoam cartons then you have to switch to the cardboard carton variety. Cardboard egg cartons, besides being able to be recycled with regular cardboard, can be shredded and mixed in your <!–more-memberlock–>compost bin and also make great plant seed starters. Simply cut small drainage holes in the bottom of each of the twelve cups, fill with potting soil, add your seeds and water. Once they germinate and you see about two inches of growth, cut the carton so that you separate the cups from one another and then plant the entire cup.

One Gallon Plastic Milk Containers
I can give you two uses for each before you send them to the recycle center. First, rinse the containers out to make sure all the milk residue is gone. Then fill to about an inch from the top with water, put the cap back on and stick the entire container in the freezer. In about a day you will have a nice solid block of ice you can use at your next barbecue to cool down those drinks. When the ice is ready, run some luke warm water on the outside so the ice inside detaches from the plastic sides. Take a utility knife and cut the container in half, in other words separating the top of the container from the bottom. This will allow you to remove the ice. Now take bottom half and drill some holes in the bottom and you have an excellent pot for flowers and plants and the top makes for a great protector against the cold air at night.

Reuse that Old Hose
Before you toss that old hose into the trash, create for yourself your very own soaker hose. Poke plenty of holes in the sides of the hose so that when you turn the water on it drips through the holes you just created.

Pantyhose, Old Socks and T-Shirts
Don’t just toss them into the trash, you can use them to tie up your plants. Tomatoes have weak stems and instead of splurging on the Velcro ties you can cut up some old socks and t-shirts and use them instead.

Newspaper
Done reading the paper yet? Is your neighbor? Good! Newspaper makes a great weed barrier and also great mulch for the compost bin. To use as a weed barrier in your garden, lay the newspaper down, cover with grass clippings, and wet it down with your hose. To use in your compost bin, shred the newspaper and just throw it in there.

Trash is only trash if you can’t think of anything to do with it. As more people get involved with the green movement, especially those that plant vegetable gardens, we will start finding even more ways to keep our garbage out of landfills.

Many home plant pest problems can be easily solved by using a little insecticidal soap. It is easy and inexpensive to mix up your own organic insect killer at home. You will be saving money on pesticides and won’t have to worry about dangerous chemicals on your food.

This recipe works best on soft-bodied pests like aphids, thrips, white flies and spider mites. These are among the most common garden pests. Insecticidal soaps kill insects by Read the rest of this entry »
