  • soil
  • While different plants have different irrigation requirements, ensure the soil around the plant remains evenly moist at all times or water when the top 1 to 1 1/2 inches of the soil feels dry. (ehow.co.uk)
  • Excessive fertiliser leads to salt build-up in the soil that causes plant leaves or only tips to turn black. (ehow.co.uk)
  • You should water most plants when the soil becomes dry to the touch, which is generally once per week. (ehow.com)
  • Use quality, pasteurized potting soil for indoor plants. (ehow.com)
  • Seeing your photo it looks like the plant needs to be repotted into a larger pot with new soil and especially since it's obvious there is a large and elderly portion of this plant sharing the space of the smaller soil level leaves. (thriftyfun.com)
  • Always water the soil not the plant leaves! (gardenstew.com)
  • Water both potted and outdoor plants when the soil surface begins to dry and avoid wetting the leaves so they aren't a prime breeding ground for mold in the future. (gardenguides.com)
  • Ground pine sheds its shiny black seeds close to the parent plant and the seeds can remain alive in the soil for up to 50 years. (wikipedia.org)
  • The high degree of ground cover from this plant blankets the soil protecting it from sun exposure and water loss, and therefore increases the quality of the soil. (wikipedia.org)
  • Cuttings should be made above a joint, be 5 to 6 inches (13 to 15 cm) long, and planted in sandy, nutrient-rich soil and allowed to root before planting. (wikipedia.org)
  • Drought can be defined as the absence of rainfall or irrigation for a period of time sufficient to deplete soil moisture and cause dehydration in plant tissues. (wikipedia.org)
  • The time required for dehydration stress to occur depends on the water-holding capacity of the soil, environmental conditions, stage of plant growth, and plant species. (wikipedia.org)
  • Aside from the moisture content of the soil, environmental conditions of high light intensity, high temperature, low relative humidity and high wind speed will significantly increase plant water loss. (wikipedia.org)
  • sunlight
  • To prevent bacterial leaf spot, keep the plant in a well-ventilated area exposed to the amount of sunlight it needs. (ehow.co.uk)
  • Since the state's climate provides increased levels of sunlight, some plants do not maximize their photosynthetic potential. (gardenguides.com)
  • Instead of focusing on gathering more sunlight with green chlorophyll leaves, the vibrant colors are used by the plant to attract pollinators and aid in the process of reproduction. (gardenguides.com)
  • These fungi are known as powdery mildews and they are usually indicative of other problems with the plant's culture, such as over watering, too little sunlight or bad air circulation among the leaves. (gardenguides.com)
  • processes
  • Needle leaves from pine trees increase photosynthetic processes within the plant and are able to regenerate damaged buds without wasting important resources. (gardenguides.com)
  • A plant responds to a lack of water by halting growth and reducing photosynthesis and other plant processes in order to reduce water use. (wikipedia.org)
  • margins
  • There are many different types of leaf margins that can be helpful in distinguishing different species of plants. (ehow.co.uk)
  • Some of the most common types are entire (with smooth margins), lobed (herbs such as cilantro have lobed leaves), serrate (saw-like edges) and dentate (indentations resembling sharp teeth). (ehow.co.uk)
  • The deeply cut leaves have spiny margins, and in early summer it bears erect, 1 m (3 ft) long racemes of white flowers with maroon bracts. (wikipedia.org)
  • water
  • Avoid causing puddles or pools of water at the base of the plants. (ehow.co.uk)
  • Excess water limits the availability of oxygen and drowns the plant root. (ehow.com)
  • Hand pick beetles off the plants at all stages of development and drop them in a bucket of soapy water. (ehow.co.uk)
  • Coat leaves in the morning with insecticidal soap if water is ineffective. (ehow.co.uk)
  • Yellowing leaves on plants usually mean too much water. (thriftyfun.com)
  • Brown leaves on plants usually means not enough water and the leaves dry out, turn brown and fall off. (thriftyfun.com)
  • Their leaves are designed to decrease water loss from evaporation and increase photosynthetic surface area. (gardenguides.com)
  • Dip a soft, white cloth in the water and wipe the mold off of the leaves. (gardenguides.com)
  • Spray outdoor plants with a strong mist of water from the hose to dislodge and rinse away mold growth. (gardenguides.com)
  • During the low-water season, it often becomes trapped in small lakes that are left behind, or stays close to the wooded edges of the forest. (wikipedia.org)
  • In nature or crop fields, water is often the most limiting factor for plant growth. (wikipedia.org)
  • On such soils some plants may experience dehydration stress after only a few days without water. (wikipedia.org)
  • This reduces a plant's leaf relative water content. (wikipedia.org)
  • Plants growing in sandy soils with low water-holding capacity are more susceptible to dehydration stress than plants growing in clay soils. (wikipedia.org)
  • A plant's root system may be limited by the presence of competing root systems from neighbouring plants, by site conditions such as compacted soils or high water tables, or by container size (if growing in a container). (wikipedia.org)
  • Also, a plant that was well-watered prior to being water-limited will usually survive a period of drought better than a continuously dehydration-stressed plant. (wikipedia.org)
  • tobacco mosai
  • Tobacco users should be extra careful to sanitize their hands before touching tomatoes to avoid introducing tobacco mosaic virus to plants. (thriftyfun.com)
  • Causing tomato leaves to appear crinkled and either lightened or mottled with dark spots, tobacco mosaic virus also may cause fruit that is brown on the inside. (ehow.com)
  • Because this disease spreads rapidly via the gardener's hands, clothes or tools, it's vital to work carefully with tomatoes or other plants suffering from tobacco mosaic virus. (ehow.com)
  • Once plants become infected with fusarium, verticillium or tobacco mosaic virus, there is no treatment. (ehow.com)
  • spots
  • However, recently, my mint and basil (thai) plants have these white spots with areas of black at the edges on them. (gardenstew.com)
  • But when I look at them (the bottoms are fine except in some areas where the spots have gone through) it's primarily the plant leaves that are closest to the window. (gardenstew.com)
  • irrigation
  • If plants do not receive adequate rainfall or irrigation, the resulting dehydration stress can reduce growth more than all other environmental stresses combined. (wikipedia.org)
  • long
  • Indoor plants add natural beauty to any room of your home, as long as they receive proper care. (ehow.com)
  • The leaves can get up to 4 cm long, and are divided into three linear lobes which, when crushed, have a smell similar to pine needles. (wikipedia.org)
  • The floral leaves are bifid (split in two parts) and ovate, while the involucral bracts are bright red, irregularly acuminate in shape (e.g., like a slipper), and about 0.043 to 0.051 inches (1.1 to 1.3 mm) in length with a long, thin tube. (wikipedia.org)

(wikipedia.org)
  • When leaving the telephone exchange, the ISDN30 cable can be buried in the ground, usually in ducting, at very little depth. (wikipedia.org)
  • characteristics

  • cause
  • As there is no single specific cause of yellowing leaves, you must assess each factor to determine your course of action. (ehow.com)
