Greater brown sedge
Carex brunnea
Greater brown sedge (Carex brunnea) is a tough, clump-forming, grasslike plant that lends itself to container growth in cooler climates due to its shape and lack of frost tolerance. In warmer gardens, it can be used as a slow-spreading but low-maintenance addition to beds and borders. Funnily enough, it was originally named Carex gracilis by the famous botanist Robert Brown, which was subsequently rejected from there already being a species named so. Thus, it was named Carex brunnea.

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 based on 10 million real cases
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
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.
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

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
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

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.
