For a long time it has been believed that the effects of global warming on agriculture and food supply is going to be a positive one. This is because the rising level of carbon-dioxide resulted for global warming will help the greeneries for photosynthesis.

Thus there will be a rise of agricultural production and food supply. The theorem received a boost after the evidence of a sharp rise of barley production as one of the effects of global warming in Iceland which was quite impossible even few years ago.

But more recent experiments and researches have revealed that the effects of global warming on agriculture and food supply are not that good after all. AN UNEP 2001 report on the global warming has predicted that USA is going to have more droughts, floods, landslides and storms.

Winter will gradually be shortened and sobered down, while summer will rise in expansion and severity. Along with this heavy rain, big storm, heavy snowfall, high sea level, increasing coastal erosion and other problems will occur.

Though as one of the effects of global warming, the overall food supply and production level is supposed to rise in USA, but the Great Plains will suffer with more droughts resulting for global warming.

Even now many effects of global warming on agriculture and food supply have been perceived. The popular maple syrup production of North east USA has diminished by 10%, moving its production zone to farther north for shorter and warmer winter.

On the other hand as one of the effects of global warming the south west USA is suffering from a water shortage which will increase in coming days. The zone has become dry for any standard agricultural production with an apprehension of resettling Dust Bowl of 1930s’ by the year 2030 for global warming.

Following a report of IPCC on the global warming, California’s snow covered Sierra Mountains can reduce in near future by up to 60-90%. This will create dire water shortage in summer, making the Central Valley area unsuitable for agricultural production for global warming. The State University of Colorado has declared that the area is going to be less productive due to effects of global warming on agriculture and food supply.

As the effects of global warming, the food supply production in Florida is going to suffer a lot due to frequent and large scale floods. Also one of the most profitable agricultural products of USA – corn will suffer a bad condition due to dry and hot atmosphere for global warming.

As another example of the effects of global warming on agriculture and food supply – with the rise of temperature by 3 to 11 degrees in this century, the production rate of the main crops – the rice, corn, wheat, barley, soybeans and sorghum – will be cut down by 3-5% for each point rise of temperature for global warming.

However with all these effects of global warming on agriculture and food supply, new attempts have been made to adjust the agricultural and food production method according to the changing atmosphere. So to fight the effects of global warming, the researchers have established new methods of production with continuous revision of models. But still the best possible process to reduce the effects of global warming on agriculture and food supply is to be established.

Growing azaleas, rhododendrons, blueberries, holly, pieris, heather, and other plants that love acidic and organics soils can be fun and rewarding.

One of my fond memories of being 12 was catching my first shad. Each spring the shad migrate up the Delaware River to end their life long journey to spawn. Their migration is like clockwork, arriving exactly on time, like the swallows of Capistrano each year. In many ways so are the flowers and buds on plants. I remember my shad and the picture of this trophy. I was standing next to a large azalea in full bloom. Each year I would see the blooms on that azalea and know that as they swelled so the shad were approaching. Thus I came to associate the blooms of azaleas with it’s time to go fishing. How smart and lucky I was. For there are so many varieties and blooming times for azaleas plus some varieties have small second flushes, that I can now say with absolute certainty that, “It’s always time to go fishing”.

There are so many varieties of azaleas and rhododendrons that experts only estimate their approximate number. There are early bloomers and late season bloomers. Some with large flowers and some with small flowers. Some are scented. There is a spectrum full of colors and sizes. Some are evergreen and some deciduous. Thus azaleas and rhododendrons are shrubs for all seasons. In winter, these plants stand out with large evergreen leaves and bring showy flowers in the spring. Throughout the summer and fall the leaves add pleasing green color to the landscape. The intense flowers of azaleas and rhododendrons make them a popular selection.

If you have difficulty telling an azalea from a rhododendron, stop worrying. Call them all rhododendrons and you will be correct. If you know how to grow a rhododendron, then you can use the same cultural principles in growing blueberries, holly, pieris, heather, and other plants that love acidic and organics soils. Rhododendrons love mild humid climates. Site selection is important. Many people come to us and report that they have had little luck in planting rhododendrons and want to try again. Our suggestion is to first look at your environmental conditions and determine if you should replant. Rhododendrons are found in nature predominately on north to east slopes. Here there is less rapid temperature changes and the drying west and south winds are shielded by natural features. Always protect azaleas and rhododendrons from wind. Plant with barriers in mind. Barriers can be evergreen screens, or buildings or slopes. Evergreen screens can help highlight the blooms. Be mindful that a corner of a building may not offer protection but actually funnel winds by the plants. Rhododendrons actually like filtered light better than shade. If your site is full shade consider a pruning of the overhead trees to allow better light penetration.

The soil that you plant Rhododendrons in should have good drainage. You can run a simple test by digging a six inch hole and filling it with water. If it is not drained in 4-5 hours you need to increase the drainage of the site. Rhododendrons have very small delicate roots. If the soil drains poorly there is probably to much clay. The roots can’t penetrate heavy clays. I would suggest a raised bed or a drain tile to carry away the excess water.

It is difficult to improve poor soils to grow rhododendrons without creating other problems. Sometimes trees with surface roots rapidly take over soils that are improved and compete for nutrients. They, after all have a head start on your new plants. It may make sense to raise up a bed a whole foot. This gives improved drainage and allows the new plants more competition free time in getting established. Make sure you have an acidic soil of 5 to 5.5. If you have a large pine tree rake up its needles and use them as both a weed barrier and a pH adjuster. There is no good substitute for quality organic materials being incorporated into your soil. Clay soils are especially enhanced by organics. Lots of ground pine bark, oak and pine leaf mulches and topsoil mixed well, works much better than peat. Peat will hold water preventing oxygen from filtering to the root zone. Peat can also hold moisture for long periods in the spring and winter. The area that you prepare should be prepared weeks before you plant. This allows the pH to change.

Most of the rhododendrons and azaleas that we sell are potted. These plants should never be planted so that their stems are below what it was in the pot. Plantings should always be about 2″ above the surrounding soil. Water the plant well after planting. Native rhododendrons have very shallow surface roots and have natural mulch and organic debris covering the surface roots. This conserves moisture and minimizes winter injury. You want to mirror the natural conditions so using decomposed pine needles and oak leaves is the best mulch. A layer of two to four inches is ideal. Keep the layer of mulch away from the stem. The mulch should not be removed. It should be with the plant for all seasons. It is the plants winter blanket. It helps keep the plant from winter leaf scorch.

If you want your beds to have designer colors such as red mulch black much, plastic fiber cloth, river pebbles etc., then plant some other plant, because these plants are delicate and conditions must be correct or you will have poor results. I don’t recommend any fertilizing of the plants for beginners. If you must add fertilizers make sure it is for acid loving plants.In nature these plants do well with low nutrient levels. Their small surface roots can be easily be hurt by over application of fertilizers. I would use no more than 2 pounds of a 6-10-4 per 100 square feet, but organic matter that is covering the plant should be perfect. Do not fertilize after July 1.

Fertilizing after this time may force growth during the winter when the plants should be dormant. The mulch can also act a a natural weed barrier. As it decomposes add more. Fall is the optimum time to make sure you have enough mulch.
