Going Organic: For the Home Vegetable Gardener

1. No one wants pests in their garden. Last year I witness first hand as a tomato horn worm decided it would feast on one of my plants without knowing what it was. Luckily, a friend recognized the damage and was able to find (and remove) the pest. Can you share some organic/natural ideas for controlling common vegetable gardens pests?

Annette: No gardener likes to have pests chomping on their vegetable plants so I use several organic techniques to be sure at least one of them will work. First, healthy soil consists of beneficial insects and bacteria that naturally repel harmful pests. Using compost and an organic soil conditioner will support the soil’s ecosystem. Second, plant companion plants among your vegetables. This will repel specific pests and disease. Invite birds and bats to your garden as they love to feed on insects. Simply set a birdhouse and birdbath near your vegetable garden to encourage them to join your backyard habitat. Bat houses are also effective for attracting pest-eaters. Last, invest in non-toxic, organic pest control products that are made from plant-based oils for on-the-spot problem solving. Happy Naturals organic pest control is safe to use right up until the time of harvest and 100% vegetable based.

Jean Ann: I always advocate for the least invasive method first. In this case, it’s the pick and stomp method…grab up those tomato worms and squish them! Identifying what is causing damage to the plant is important in deciding what intervention is best. For example, if you know that it is a caterpillar, there is a parasitic wasp (Trichogramma) that can be purchased and released in the garden that will eliminate several pests of that type. Or, gardeners can use bacillus thuringiensis (or Bt), a treatment with naturally occurring bacteria, to address the same problem.

Maria: When thinking about natural pest control, keep in mind that there are three main areas of control; 1) Cultural Controls, 2) Physical Controls, and 3) Biological Controls. Some of my favorite cultural controls are keeping a nice healthy bed of soil for my plants to live in and also planting them where they want to be (i.e. sun, shade, drainage, fertility, etc). Physical controls are many but include tactics like hand picking large insects such as tomato worms, removing aphids with a jet of water from a garden hose, putting up a barrier to keep birds off your berry plants, etc. Some of my favorite controls are biological controls. I love to watch the checks and balances of nature. If you see any white cocoon-like structures sticking out of the back of the tomato worms in your garden, beneficial insects are already doing their job by parasitizing that worm. To encourage beneficial insects in your garden do a little research on farmscaping. You can use those same tactics on a smaller scale in your home garden.

2. What about companion planting? Does this work or is it a gardening myth? What are some of your favorite planting combinations?

Annette: I personally love companion planting and have been using this easy technique for as long as I have had a vegetable garden. My favorite plant combos are sage to control tomato worms; mint to control cucumber beetles; parsley to deter carrot flies; and chives to reduce aphids with my roses. For a complete list of effective companion plants go to http://eco-gardeners.com/2010/04/companion-planting

Jean Ann: There is no research that proves the effectiveness of companion planting for keeping bugs at bay. However, crop diversity is important in maintaining biodiversity in your garden. That said, interplanting different types of plants, can prevent pests from moving right from one plant to another. If you have rows and rows of tomatoes (or plants in the tomato family) all sharing the same space, hornworms don’t have to go very far to find their next meal. Try adding a row of corn or beets between tomato beds.

Companion planting has other benefits, too. I like to combine nitrogen-fixing plants with those that take nitrogen from the soil. By planting winter squash and beans together, a symbiotic relationship is formed. The plants receive the nutritional benefit and the soil isn’t depleted.

Maria: Companion planting is an older concept, but still a really good one. The idea is to plant your plants all mixed together instead of lining them all up in little rows. This makes the insects and diseases hunt for the plants instead of giving them a ready-made
buffet. It tips the scales a little more in our favor. In this manor you can mix in plants that attract your beneficial insects and also plants that repel the pests. Plants that provide food (pollen) and cover such as dill and coriander are good draws for beneficial insects. Plants such as marigolds and tomatoes are good repellent crops.

3. Disease is another issue that many deal with in vegetable gardens. Can you share some of your best tips for preventing common vegetable garden diseases without the use of chemicals?

Annette: Disease on vegetable plants is usually always the sign of poor soil as a result of nutrition depletion, and poor aeration and/or drainage. Preparing your garden soil in late winter/early spring will greatly reduce disease on your veggies. Using compost and an organic soil conditioner will replenish lost nutrients/micronutrients, break up heavy clay, add consistency to sandy soil, and provide aeration for necessary oxygen flow. Happy Naturals organics has a foliar feed made with organic soybean that is an excellent leaf protection for disease spreading from plant to plant.

Jean Ann: Unfortunately, there are very few diseases that can be treated, organically or not. Some mildew can be treated with a baking soda and water combination. But for the most part, once a serious disease like blight has set in, the best thing to do is pull up the crop. The key to controlling disease is in prevention. Taking small steps in advance can save you the stress of trying to control it later.

A few tips for disease prevention:

-Make sure plants don’t become overstressed. Water on a regular basis, use mulch to keep the group temperature steady, fertilize only when needed. L
-Leave or make space for air circulation by pruning plants and avoiding plant crowding.
-Ensure your beds have excellent drainage. Amend soil with compost for optimal drainage.
-If you have problems with mildew, don’t water overhead, especially at night. Use soaker hoses or water early in the morning to give plants a chance to dry.

Maria: Many plant diseases seem to attack weak plants. Doing regular soil testing and adjusting your soil fertility is a good way to find out what your plants need and how much. Another one of my favorite tactics for controlling plant disease is mulching. Many of the most common diseases are soil-borne and introduced to the plants through water splashing up on the leaves. Try using mulch around your plants to keep soil from splashing. Also, try drip irrigation instead of overhead; it is better for your plants and more water conscious.

4. What vegetables/fruits are the hardest to grow organically? (i.e. because they are more subject to disease/pests/etc. than other plants) What are the easiest to grow organic?

IMG_4079-2rhubarb

Annette: The most difficult vegetables and fruits to grow organically are those that are going to contain harmful chemicals and the least amount of nutrition. I am making fun of this question simply because growing organically is so much easier than expected and the techniques can be successfully used with all edibles.

Jean Ann: Most vegetables are easy to grow organically. I think the biggest challenges are tree fruits like apples, pears, and plums. Pests like the coddling moth and the plum curculio are harder to treat with organic methods. I suggest that new gardeners start with fruits that have fewer pest problems (like berries and rhubarb) then add fruit trees as they learn more about organic gardening methods.

Maria: The best thing to remember is that growing plants where they want to be makes our task as gardener much easier. Plants that like the climate where you live are likely to be easier for you to grow organically. For easy to grow organic vegetables I like squash, beans, tomatoes, peppers, radishes, and lettuces and other greens. Organic fruits vary widely depending on where you live. When buying a fruit tree or bush for organic production the varieties are endless. Try to pick a variety with resistance to the diseases that are most common in your area.

5. As seasoned organic vegetable gardeners, do you have any other suggestions for beginners? What knowledge do you have now – after years of experience – you wish you’d had when you first began growing organically?

Annette: My suggestion would be to plant as many vegetables from seed as possible; ones that can be planted (sown) directly in the garden soil. Those veggies do the best and are most resistant to disease and pests than buying already grown plants since they have not been fed toxins and have not been on tables with infested plants.

Jean Ann: Sketch out a plan for your garden ahead of time…then reduce it by two-thirds. Most of us overplant in our eagerness to embrace our new passion. This can lead to a lot of stress and work as the summer wears on…something that can turn it from something you love into something you hate. Further, the sketch enables you to keep track of your plantings so that next year, you can practice crop rotation.

Maria: Be patient and relax. Gardening is supposed to be relaxing and enjoyable isn’t it? When I first started growing organically, I was frustrated that changes happened more slowly. But, I think that I was missing the good things that were happening but that were perhaps a little less obvious to a novice. My soil was building in nutrients and quality as I was going along. The organic matter content was increasing which led to better water holding capacity. Beneficial insect populations were increasing after growing without the use of insecticides or herbicides and a certain balance was happening in the garden as a whole. And then, yields went up! And not only was it bountiful, it was beautiful and healthy as well. Be patient and diligent and it will come.

6. If home vegetable gardeners were to make just one change towards growing more naturally, what would you suggest that it be?

Annette: Compost- it’s the best eco-gardening practice you can do to ensure the health of your plants and the future of our environment.

Jean Ann: I suggest the switch from standard fertilizers to organic. It is super easy and something that causes almost no effort on the part of the gardener. The second would be to learn a couple of strategies for organic pest management. Yes, I realize I listed two…but hey, the first one is so easy, it doesn’t really count.

Maria: In garden centers today there are so many all-purpose fertilizers that it is hard not to be tempted. Each year home gardeners pour a wealth of money and nutrients into the soil, trying to keep their green places as green as possible. The problem is, when we think of pollutants, we usually think of pesticides, not fertilizers. But nutrient pollution is hard on the environment as well. If I could implement one change, I would ask people to do soil tests before fertilizing to make sure that these fertilizations are needed.

    I loved this post–so interesting! Organic gardening not only sounds better for your food and for the environment (both great things), but it also sounds like you are more involved with your plants. You are really aware of their growth and health, as opposed to just watering and spraying some Round-Up now and then. This is what gardening should be!

    Great info here. Each year I learn a little more by reading but more by doing and seeing how my soil and different areas accommodate different plants, etc. The companion planting is something I've tried and to me, it's more pleasing to the eye and "natural" looking when flowers and vegetables, etc. are combined next to each other.Question though, how close to companion plants need to be in a garden? A couple of feet or will several feet or yards do the trick?

    this was a very interesting post! This is my first year gardening and I am trying to be as organic as possible. I did spray my plants with an organic pesticide the other day because beetles were attacking them, but I picked one that promised it was safe to spray the same day as harvest.

    I haven't planted our garden yet since we are in MN. I do have several seedlings growing and I will buy the rest at greenhouses. I've not had any pests problems other than the local (aka in our back yard) rabbits. Last year they ate everything within 48 hours except the tomatoes and rhubarb. That was not a happy day! We have already pounded in the stakes and chicken wire will surround the garden within minutes of planting this year!I would love to learn more about composting. We have a small raised bed garden and I'm not sure how much it would need.pong7@comcast.net

    I've got all my seedlings started and sitting in the greenhouse. I hope it warms up though so I can plant them outside. I've been trying to stick to completely organic gardening (bought some nonorganic seeds as there isn't much of a selection around here) and my stuff is growing great, even with my black thumb!

    This article has excellent information about companion planting.. something I haven't read much about until now. It makes sense though, but I really liked the points about creating the symbiotic relationships– keeping every other plant with one that gets CO2 from the soil or from the air… makes sense.
