Are Brazilian Pepper Trees Toxic?
Are Brazilian Pepper Trees Toxic?. The Brazilian pepper tree is a highly aggressive, prolific and hardy shrub. This subtropical plant species is a relative of poison ivy. Physical contact with sap can cause severe skin irritation in the form of rash and itching. Airborne bloom emissions can cause sinus and nasal congestion, chest pains, sneezing, headaches and eye irritation to people in close proximity to the plant. If consumed, the bark, leaves and fruits of the Brazilian pepper tree are toxic to humans, other mammals and birds.

Are Walnut Trees Poisonous?
Are Walnut Trees Poisonous?. Walnut trees produce a chemical known as hydrojuglone. It is found in every part of the tree. Hydrojuglone by itself is harmless and odorless. However, when oxidized by compounds in the air and soil, hydrojuglone is transformed into a toxic allelochemical known as juglone. Allelochemicals are secretions that essentially poison some types of nearby plants by inhibiting physiological processes, such as germination, growth and nutrient and water uptake. While all types of walnut trees produce juglone, only the black walnut tree typically produces quantities sufficient to impact surrounding plants. Juglone-sensitive plants placed near black walnut will inevitably yellow, wilt and die.

Poison Ivy Reproduction
Poison Ivy Reproduction. Poison ivy is a perennial woody weed that is native to North America. It is most frequently observed in disturbed sites along roads, railroads and canal rights-of-way. It is also quite common in woodlands, floodplains, rocky slopes and lake shores. It prefers sites with moderate levels of sunlight and soils with high calcium content. Poison ivy reproduces by seeds, which are readily dispersed by animals and birds, and by creeping roots. Consequently, look for this plant at the base of trees, edges of woods and along fence rows, where birds perch and nest.

Sprays To Control Anthracnose In Mangoes
Sprays to Control Anthracnose in Mangoes. All commercial mango operations in humid climates require regular fungicide spray applications to protect against anthracnose, a destructive disease that can severely reduce fruit production. While some varieties of mango may have higher resistance to anthracnose, all mango trees are somewhat susceptible to this troublesome disease. Fungicides are a helpful mechanism for controlling anthracnose, when adequately and properly applied. For best results, provide thorough coverage and timely applications, and do not spray with chemicals more than three times a year. Reduce the pressure on fungicides by using nonchemical control measures, such as careful cultivar selection and consistent tree pruning.

Organic Vs. Non-Organic Soil
Organic Vs. Non-Organic Soil. All soil is composed of organic matter. The terms "organic" and "non-organic" refer to the process and the chemicals used to maintain soil. Conventional, non-organic farming relies on synthetic fertilizers, pesticides and soil amendments to promote growth and discourage disease. Organic soil uses only natural, non-synthetic materials to obtain similar, or better, results.

What Is "Moss Rock"?
What Is "Moss Rock"?. Moss rock is a type of sandstone or flagstone, usually with brown and red undertones, that is covered with moss. It is commonly used within garden pavers, water features and landscape walls. Rocks used to make moss rock are harvested from quarries nationwide; however, each area will produce products that vary in composition and appearance. Large harvested blocks of moss rock are chopped up in varying sizes and shapes. When purchasing moss rock, some moss will be present. Over time, more moss will develop on rocks that are properly maintained and positioned.

What Soil Type Is Needed For A Coffee Tree?
What Soil Type Is Needed for a Coffee Tree?. Coffee plants are a versatile species that may be grown as specimen shrubs or small trees. Coffee trees will tolerate a wide range soil pH, though lightly acidic soil is ideal. Soil must be well-drained and amended with organic materials. Soil of volcanic origin is preferred. Coffee trees are not salt tolerant.
