Trivia and Interesting Facts
In 1754, Lin Nai founded the true sedge genus. True sedge is also one of the main components of the flora in China. It is the dominant grass species in the lowest forest layer in many areas. In some forests, the lower vegetation is mostly true sedge.

Common issues for Greater brown sedge 'Jenneke' based on 10 million real cases
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Leaf tips withering
Low air humidity can cause the edges of the leaves to dry out.
Solutions: If your plant has only a few dried tips, complete the following: Increase humidity. Increase the humidity around your plant by misting it with a spray bottle daily. Alternatively, you can use a humidifier. Water plant. If your soil is dry, water until the soil is moist but not damp. Water again when soil dries out. If a large portion of the leaves is suffering from dry tips, complete the following: Prune away affected tissue. Using sharp and clean pruning shears, remove the dried out tips using clean cuts to avoid harming healthy tissue. Plant tissue will heal on its own, but you can apply a pruning seal for extra protection.
Leaf rot
This pathogen can cause the leaves to rot.
Solutions: Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden. In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label. In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
Both leaves and blossom on the tips of branches will go brown and wither.
Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
Any fruit that does appear will turn wrinkled and fail to develop.
Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.

Leaf tips withering
Low air humidity can cause the edges of the leaves to dry out.
Symptom Analysis
The tips and the edges of the plants’ leaves are dried out and brown. They may be crunchy when touched. This is caused by low humidity and/or a lack of water.
Solutions
If your plant has only a few dried tips, complete the following:
Increase humidity. Increase the humidity around your plant by misting it with a spray bottle daily. Alternatively, you can use a humidifier.
Water plant. If your soil is dry, water until the soil is moist but not damp. Water again when soil dries out.
If a large portion of the leaves is suffering from dry tips, complete the following:
Prune away affected tissue. Using sharp and clean pruning shears, remove the dried out tips using clean cuts to avoid harming healthy tissue. Plant tissue will heal on its own, but you can apply a pruning seal for extra protection.
Prevention
Many houseplants come from moist tropical areas with high humidity.
To prevent dry and brown tips, you should complete the following:
Water regularly. Water when soil is dry.
Keep humidity high. Keep moisture high by regularly misting the air or using a humidifier.

Leaf rot
This pathogen can cause the leaves to rot.
Overview
Leaf rot is very common among both house plants and garden plants. It affects foliage and occurs mainly when the leaves become wet due to rain or misting by the gardener. The cause is fungal disease and this is facilitated by the fungal spores adhering to wet leaves then penetrating the leaf and expanding rapidly. Damp conditions and poor air circulation will increase chances of infection taking place. Another factor are leaves that are damaged or have been penetrated by sap sucking insects that facilitate plant penetration.
Symptom Analysis
Spores are able to cling to a damp leaf and penetrate, often through an existing wound.
A small dark brown mark appears which expands rapidly as sporulation starts to take place.
Quite quickly these bull's eye like circles can link together and the whole leaf turns dark and loses texture.
Leaf drop occurs.
Disease Cause
These symptoms are caused by a bacterial infection invading the plant. Bacteria from many sources in the environment (air, water, soil, diseased plants) enter a plant through wounds, or in some cases the stomata when they are open. Once inside the leaf tissue, the bacteria feed and reproduce quickly, breaking down healthy leaves.
Bacterial infections threaten most plant species, and are more prominent in wet weather that more easily transfers the bacteria from plant to plant, or from soil to plant.

Prevention
Clean up garden debris at the end of the season, especially if it contains any diseased plant tissue. Diseases can overwinter from season to season and infect new plants.
Avoid overhead watering to prevent transferring pathogens from one plant to another, and to keep foliage dry.
Mulch around the base of plants to prevent soil-borne bacteria from splashing up onto uninfected plants.
Sterilize cutting tools using a 10% bleach solution when gardening and moving from one plant to another.
Do not work in your garden when it is wet.
Rotate crops to prevent the buildup of bacteria in one site due to continuous cropping.
Use a copper or streptomycin-containing bactericide in early spring to prevent infection. Read label directions carefully as they are not suitable for all plants.
Ensure plants are well spaced and thin leaves on densely leaved plants so that air circulation is maximised.
