Dieback: Tips and shoots dying on live plants. Often the dieback will progress up the stem or branch to the main stem so it is important to cut off the dead part.
Diocecious: A plant that has either male or female organs.
Dieback: The death of tree branches starting at their terminal bud (the last bud on a branch) and moving back up the branch toward the trunk.

DIEBACK - A process caused by disease or pests. It is the death of the tips of branches and shoots. It will progress until the whole plant dies.

DIEBACK: This condition is water, nutrient, disease, insect, or pruner inflicted in the area where part of the plant is dying.

Twig dieback occurs when infection advances from blighted leaves directly into the stems. Twig death tends to be concentrated in the lower branches of dogwoods, hence the early name of the disease, "lower branch dieback.
Progressive dieback over time kills or affects larger limbs and ultimately the entire tree within two to three years of first symptoms. Cankers within the tree are rarely visible on the bark exterior.
Commemorate the dieback of plants due to frost. For plants with large leaves such as banana or canna, tie up the dead foliage in a bunch to resemble haystacks. The plant "corpses" can be used to hide creepy sculptures.
Severe infection may produce a variety of effects, including defoliation, dieback, severely blemished fruit, reduced fruit quality, and premature fruit drop.

If you have had trouble in past years with getting your wisteria to bloom, there is a chance that the plant may be suffering from winter dieback which kills the blossom buds.
It is from the tropical dieback disease Phytophthora cinnamomi. There is no single solution to this disease that has devastated areas of the park, particularly along walking trails and roadways.
Dieback Death at the tips of a plant, usually the result of disease or damage. Dioecious A plant having unisexual flowers, with each sex on a different plant. Disbudding The pinching off of selected buds to benefit those left to grow.
On trees it causes twig canker and dieback, leaf and shoot blight, and often defoliation. The fungus that causes Anthracnose overwinters in twigs on the tree and becomes active when temperatures permit its growth.
When they do, it is usually followed either by slow growth for several years or massive dieback. A few species flower en masse no matter their location and climate, synchronizing their dieback/suicide across oceans and continents.
Since there's no winter dieback, the plant gets a head start over the competition. It thrives in partial shade and moist soil but seems to tolerate sunny conditions as well. It's also a prolific seeder.
With winter dieback, a 12-year-old Manchurian walnut (Juglans mandshurica) has attained a height of just 45 centimetres, and the bristlecone pine (Pinus aristata) and Ponderosa pine (P. ponderosa) looked so sorrowful that I took them out.
Plant it in an area where is gets direct sun early in the day and avoid the midday full sun, as that will cause the foliage to dieback prematurely. Maintain even moisture during the growing season.
Wet conditions also encourage fungus to attack your lawn and cause rot. These diseases create dieback, damage, and even kill plants. Once infection occurs, little can be done to help.
The feeding and tunneling of the larvae stop the flow of nutrients and water in that area, twig and branch dieback result.
Typically the symptoms first appear on one plant and later on surrounding plants: yellowing of foliage (particularly at the shoot tips); leaf shed; slowed plant growth, and limb dieback. Smaller plants may remain symptomless until after transplanting.
Severe winter weather, especially cold winds, may cause some dieback, and can cause flower bud damage on those buds showing color. The bloom period on japonicas is often determined by our winter weather.
A mangled cane is a great place for fungal disease spores to hide out, lying in wait to cause problems later or causing cane dieback now. Pruner blades should be disinfected with alcohol as you move from plant to plant.
Zinc deficiencies are characterized by small leaves, rosetted (highly branched, short, bunchy) growth, twig and limb dieback and sometimes tree death. Leaf veins have a band of green on each side, giving the leaves a striped appearance.
In zone 9, plants will survive some winters, or suffer winter dieback but return from their roots. In all other zones, treat it as a summer annual, or bring it indoors for winter before the first hard frost.
Remove the ends of shoots on shrubs damaged by frost, even if they should not be pruned now. This prevents the spread of disease and further dieback.

Planting and feed ...
Poor drainage and damp soil conditions favor root-killing disease fungi that can develop as either root rot or dieback. Visit the Ohio State University Extension for more information about root problems on plants.
Having little oxygen within the water garden can lead or contribute to dieback of the plant, causing leaves to wilt and yellow. Be selective when adding water plants to your garden and observe how they inhabit the space.
Without enough oxygen, plant roots suffocate and die. Plant parts above ground exhibit symptoms of this stress: wilting, yellowing, and drying foliage, leaf drop and twig dieback may all occur. Constant overwatering kills most plants.
