For home gardeners, nothing is more frustrating than seeing their work destroyed by pests and diseases. The disease occurs when environmental conditions are suitable for the growth of pathogens on susceptible hosts. Some pathogens attack a variety of plants, while others attack only specific plants. In addition, some pathogens can attack all parts of the plant, while others attack only selected tissues. Many types of organisms cause plant infections , but the top five types of plant pathogens are fungi, water molds, bacteria, viruses, and nematodes. Adverse environmental conditions may also lead to non-infectious diseases of plants, called diseases. Adverse conditions include inappropriate soil pH, nutrient deficiency and toxicity, soil compaction, excessive water content, and herbicide destruction. Plants weakened by adverse conditions may be more vulnerable to pathogens. The following is a brief introduction of several common plant diseases, symptoms and solutions, I hop...
Trimming is among the most reliable means to adjust and guide the growth of a cannabis plant. If you're seeking to limit the dimension of your plant, promote side branching, delay the onset of flowering, or increase yield, trimming checks all packages. It may feel counterproductive to trim parts of your plant as it expands. However, by pruning ineffective development, you can reroute the plant's energy as well as sources into establishing high-quality flowers. While trimming is sensibly straightforward, it's likewise an ability that comes to be polished and less complicated with the method. These pruning pointers and also tricks should assist in demystifying the procedure. Why do you trim marijuana? Pruning refers to the process whereby tiny, certain sections of the plant are cut to motivate healthy growth. At its most basic level, trimming eliminates development that is harmed, ineffective, or blocking sunshine from reaching budding flowers. Pruning describes the procedure...
In A Nutshell Your best option is to add organic matter and grow plants that do well in alkaline soils. The Whole Story Technically, all soils with a pH higher than 7.0 are alkaline, or "sweet," but most garden plants tolerate a pH up to about 7.5. Alkaline soils are generally composed of basic (high pH) parent materials such as limestone (calcium carbonate). High-pH soils are more prevalent in arid climates, because rainfall does not leach the calcium and other basic materials out of the soil. Soil pH affects nutrient availability for plants, and in soils with a pH over 7.8, iron, zinc, and phosphorus deficiencies are common. Lowering soil pH is a slow and challenging process. "The truth is, lowering soil pH is hard, because the limestone in the soil continually dissolves," says Jessica Davis, Ph.D., a professor of soil science at Colorado State University. Davis recommends getting your soil tested to determine its pH, lime content, soil texture, and...
