Organic gardening – General Notes on Pest Control Approaches in horticulture

Pest Control Approaches

Chemical horticulture fights off invasive pests with specific insecticides. They may be effective and fast-working at the beginning, but their long-term use may result in the raise of the insects resistant to the used insecticide. To kill those, more efforts will be needed, and the use of the different and stronger chemicals may be necessary. Moreover, killing enemies in the garden, any insecticide will inevitably eliminate predator insects (natural control bugs). And their lack will cause multiplying of the harmful pests. Consequently, a gardener will have to search for some other options to defeat the invasive populations.  

Organic horticulture, on the other hand, offers pests control through the studying and understanding their life cycles and peculiarities, as well as through the combined use of such methods as:

-           plants selection (pests and disease resistant plants are chosen for a garden);

-           companion plants growth (planting those crops that fight off pests and insects);

-           annual changing of the plants location to disrupt the reproduction cycles of the invasive species;

-           the use of row covers during the periods of pests migration;

-           employing insects traps to reduce the population of the pests;

-           increasing the number of predator insects and beneficial organisms.

In addition, organic gardeners usually allow some pests to live in the garden, carefully controlling their level though.

How to Identify and Manage the Basic Types of Garden Insects

Learn to identify and manage three basic types of garden pests

Why is it when 97% of the world’s insects are considered to be either beneficial or harmless, your garden attracts only the remaining 3%  that are considered PESTS? Although it may seem this way, there are both “good” and “bad” insects in your yard.

There is a constant battle going on to maintain a balance between these two groups. Toleration of some pests should be allowed as they provide a food source for the beneficial insects, allowing them to thrive in your yard and keep the pests in check. However, even in the best of gardens, uncontrolled outbreaks do occur. Preventing an infestation of bugs is an important part of gardening. By taking several precautions and putting forth a little bit of effort in the beginning, you will hopefully be rewarded with (almost) pest-free veggies and flowers.

Why are some bugs in your yard a good thing? A vast majority of the insects in your yard provide many services that improve your garden and lawn. Insects help pollinate the blossoms, which lead to more fruit, vegetables, flowers, and seeds. Insects improve the soil condition by crawling through the surface layer. Droppings and dead bugs increase the fertility of the soil. Earthworms and centipedes also help aerate the soil during their travels. Insects keep the numbers of bugs in line by capturing and eating other types of insects

Indoor Hydroponic Garden : Use Clones for a Quick Start

Cloning, or taking cuttings of, your favourite plants is the very best way to perpetuate their existence. It’s also the best way to get them started for an indoor hydroponic garden.  For instance, I had a very successful Rosemary plant growing on my kitchen window-sill. However, it was in dirt and I really don’t like dirt in the house. I took cuttings from it and ended up with three new healthy clones that I planted in a LECA (small, clay pellets) medium in my indoor hydroponic garden.

With  an indoor hydroponic garden, you can keep it constantly fresh with new clones. You never need to be without a special herb, flower or vegetable you really like ever again. Here are a few lighting tips to get perfect clones for your indoor hydroponic garden.

Unlike when you start seedlings, clones need light from day one after rooting. It’s a good idea to start with lower and diffused light intensities from sources such as T-5 or T-8 fluorescent lighting. During the first few days, the cuttings will do best with just one or two 24 watt strips over the top of a standard 10″ x 20″ propagation tray in your indoor hydroponic garden. You can gradually increase the light intensity after a few days by lowering the light fixtures closer to the propagation dome. However, make certain the temperature doesn’t rise in your indoor hydroponic garden  above 85o F/29o C inside the dome after making this adjustment.

How to Plant a Cutting Garden

Grow a cutting garden and enjoy flowers indoors and out

If you feel guilty when you cut flowers in your garden, worrying that you’re destroying nature or leaving gaps in your flowerbeds, it may be time for you to plant a cutting garden, says the American Association of Nurserymen (AAN). A cutting garden is designed to provide flowers for indoor arrangements, and it will give you a new perspective on removing flowers from your garden.

Choosing the Right Flowers and Plants

As with any garden, the first step in planning your cutting garden is to select plants that grow well in your part of the country. Ask the experts at your local garden center for their suggestions, and keep in mind your soil conditions, the amount of sun or shade your garden receives and how much it rains.

Selecting a Color Scheme

After you’ve decided which plants will thrive at your site, choose a color scheme, whether bright and vivid primary colors, soft and muted pastel shades or dusty earth tones. Since the purpose of a cutting garden is to grow flowers to use indoors, think about how flowers of certain colors will look when you place them in main rooms of your house.

Finally, plant flowers and plants in such a way that no one will notice that you frequently forage for new material for your indoor bouquets. One way to achieve a continuously balanced look in your cutting garden is to group your plantings by color, so that when you clip several blue flowers one day and several yellow flowers another, the overall appearance of the garden is still one of continuity and growth.

Organic gardening – General Notes on organic horticulture Organic gardening systems

Organic horticulture employs the crucial principles of organic agriculture for the successful herbs, fruits, vegetables, flowers and ornamental plants growing. These principles concern the management of pests in the garden, soil composition and conservation, etc.

General Notes

Mulches, Double Digging, compost, Vermicompost, cover crops, mineral supplements and manures are the main constituents of the soil mixture in this kind of gardening in contrast to the commercial farming. Organic horticulture expects to minimize the risk of insects, fungi, and diseases development with the help of maintaining the high quality of the soil. Nonetheless, sometimes it is still necessary to use insecticidal soaps and sprays, pheromone traps, or other pest-control means, created especially for organic farmers.

Experts define five fields of horticulture:

-           olericulture, which stands for the production and marketing of vegetables;

-           pomology that means the production and marketing of fruits;

-           floriculture, which is the production and marketing of floral crops;

-           landscape horticulture that includes the production, marketing, and      maintenance of landscape plants;

-           and finally, post harvest physiology that studies and practices the preservation and maintaining of the quality of horticultural crops

All these areas can utilize the key principles of organic gardening.

Organic horticulture employs the methods and uses data, which have been collected for thousands of years. Generally speaking, this type of gardening is based on the natural, long-term processes and eco-friendly, global approaches, in contrast to horticulture, based on the use of chemicals that speed up the processes and aim at the separate results and reductionist strategies.

Hydroponic Gardening: What makes it Different from In-Ground Gardening?

What makes hydroponic gardening different from traditional in-ground gardening is a soilless growing medium. No dirt! All plants require support, to be held up. This basic requirement is dealt with by soilless growing mediums which are inert, mostly non-organic materials.  Non-organic refers to the medium not being derived from living organisms, unlike soil, which is. There are a perplexing jumble of growing mediums available for hydroponic gardening. Generally speaking, these mediums are porous, light and coarse, allowing oxygen and nutrients to be easy accessible  to the plants roots.

Some of the most common used in hydroponic gardening are:

Coconut Coir ~ This is produced from the husk that surrounds the coconut shell. Made up of millions of tiny micro-sponges, it can absorb and hold up to eight times its weight in water, perfect for hydroponic gardening. It lasting three times as long as peat moss so is fairly sturdy. It is also called palm peat, coco, or just coir.  Some of the advantagesof this medium  for hydroponic gardening are better water retention and aeration.  The disadvantages of coconut coir are its breakdown after several uses and some drainage issues.  It is often mixed with other media to improve drainage for hydroponic gardening.

L.E.C.A / Lightweight Expanded Clay Aggregate ~ This is clay which has been heated under high temperatures until it puffs up.  It makes a very coarse medium as the clay balls are about 1/4″ across. Superb drainage, holds moisture, stays put and is reusable after sterilization to continue with your hydroponic gardening. These are just some of the advantages of this medium. On the downside, it doesn’t hold moisture as well as mediums like coconut coir and can be more costly.
