Look beyond the discoloration for piercing, sucking insects that are causing the discoloration. Often aphids, whiteflies and scale insects are feeding on the undersides of leaves and along stems and producing excreta that falls on the leaves. A sooty mold fungus then lives on the nutrient-rich excreta to produce the unsightly leaves. Some insect activity and sooty mold growth can usually be ignored, usually on older trees.

Macadamia trees really do not need to be trimmed, but you can if you don't like the shape of them. If you open the top so the sun light will be striking the tree it is a good idea to cover that part of the tree with "tree suntan lotion." Tree suntan lotion is a mixture of 50% white latex paint and 50% water.

This is an indication of a fungal infection. Fungal infections are usually the result of warm temperatures, high humidity and low light levels. Treat the plants with a systemic fungicide such as Phyton 27.

Leaves turning yellow and dropping off is how a plant responds to stress. The stress can be caused by being too wet, too dry, too hot, etc. If you contact one of our plant specialists, we can discuss your situation with you and determine what might be happening. Ficus plants will frequently react to the stress of being moved from one location to another and will drop leaves for the initial 2-4 weeks as they become acclimated to their new environment.

Sooty Mold - Appears as a black, sooty growth on the upper side of leaves. Is harmless, but indicates that an insect was or is present (usually aphids, whiteflies or scales). Whiteflies. As these piercing-sucking insects feed on the undersides of the leaves, they secrete a sticky, clear fluid that drops onto the leaves below. Sooty mold grows upon this secretion. Sooty Mold Water or Varietal Problem. The problem of splitting fruits usually occurs in the early fall.

The black spots are a fungus disease called Tar Spot. It infects Norway maple (including all of the horticultural forms such as "Crimson King"), Silver maple and Freeman's maple. The disease infects leaves late in the season and has little impact on the overall health of the tree. The disease is already widespread and sanitation (leaf removal) is not effective in reducing the infestation level for the following year, so let the leaves decay under the trees to at least improve the soil health.

The old leaves naturally turn yellow and fall off as new leaves are produced. If your new leaves start to turn yellow, the first thing to check is the amount of light your orchid is receiving (review the culture sheet for the genus/species of your orchid). If light is not a problem, then check to see if you orchid is being subjected to low temperatures. There are also orchids that will lose all of their leaves naturally like the Dendrobium nobile hybrids do and will appear to be a "dead stick.

Nashville tap water contains approximately 1 ppm phosphate. Available iron will chemically combine with this phosphate forming a compound which is insoluble by the plants. An iron deficiency condition known as iron chlorosis may result in these plants. The plants turn yellow and the leaves and stems both become very brittle. Fertilizers containing iron supplements will correct this condition.

Yellow leaves can be a symptom of overwatering or a mineral deficiency. Clematis need regular watering but is it is important not to let them become waterlogged. Clematis are heavy feeders. The ACS endorses Gro-Power Fertilizer because it is an organic soil conditioner as well as a fertilizer and it contains the necessary minerals to keep clematis healthy.

Blackspot is a fungus that causes black spots about 1/16 to 1/2 inches in diameter to form on the leaves and sometimes stems. The infected leaves later turn yellow around the spots and eventually fall from the plant. In bad cases, blackspot can severely defoliate a rose bush. The conditions that promote blackspot are wet leaves, splashing water and warm temperatures. Here are some ways to combat blackspot. Most of these methods also apply to preventing and treating powdery mildew.

First of all the process is called oxidation and its a natural process that occurs due to contact of the silver with the air (we all know that Jewish silverware behind closed glass doors becomes black much slower). To preserve your Judaica crafts shiny for a long time we recommend that the objects be softly wiped every two weeks. This will prevent the silver from becoming yellow or black.

This is a chemical reaction with the metalwork and the pollutants. Sulphur dioxide reacts with rain to produce sulphuric acid which can speed up the rusting process of many metals. It can also react with some metals and show up as a black deposit.

Health-and-Fitness:Depression] Depression can affect our sleep in many ways. Some of us sleep longer and others find themselves waking up in the early hours of the morning, unable to go back to sleep. Health-and-Fitness] Arthritis is known to affect around forty percent of the Americans and over fifty percent of the people globally. This is one disease that is responsible for the maximum amount of pain worldwide and thousands of dollars have been spent on pain relief medications because of this.

The Teenshare staff always meet with you after a placement ends and discuss any issues that developed during the course of their stay. It gives the foster carer and the staff the opportunity to stand back and reflect on the placement. We always ask foster carers to be aware of their own needs and to look after themselves so that they can be the best people they can when the young person enters their home.

If this happens to your Wave Petunia plants, it may be a sign the plant needs more fertilizer. A regular application of a soluble fertilizer every 10 to 14 days is recommended. Applying a slow-release fertilizer when you plant is also beneficial, although it may be depleted by late Summer. The use of a soluble fertilizer throughout the growing season is recommended, even if slow-release has been used.

The answer to this question depends upon which leaves are involved. Yellowing of old leaves on backbulbs is a normal part of the aging process. Therefore, this should not be of concern. However, yellowing of newer leaves is a sign of trouble. Orchids with yellow leaves are an indication that the plant is suffering from either too much light or insufficient feeding. Increase the shading and apply orchid nutrients as directed.

Azaleas are acid lovers. Certain minerals, including iron, are more available at lower pH values. Yellow leaves on azaleas can indicate an iron deficiency because (1) not enough iron is present in the soil for the azaleas to utilize, or, more commonly, (2) the pH is too high to release the iron that is present. Azalea fertilizer is usually a sufficient acidifier to keep the soil within the proper pH range for maximum nutrient availability.

Brown edges are often simply windburn. This is caused by wind drying out the edges of the leaves. More water can make up for the drying factor of wind. The leaves of deciduous trees will often look "tired" in the fall, as they are getting ready to drop. Just wait and watch. Fresh new leaves should emerge in spring.

If it's fall time, it's okay. If the leaf should be green and it's not, more than likely it is iron chlorosis. Other possibilities are spider mites, over-watering, or diseases. Walk through our online diagnostic clinic.

Leaves and grass clippings must be placed in brown paper composting bags or in a trash container with handles that is clearly marked "yard waste". Labels are available at the Municipal Services Office. Yard waste containers must be set at least two feet away from other containers. Yard waste is collected weekly between April 1st and November 30th of each year.
