Aphids
Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.
Solutions: Aphids can be controlled with physical, biological, and chemical methods. For less severe cases: Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants. Use a hose with a good stream of water to spray them off. Introduce beneficial insects such as ladybugs and lacewings. For severe cases: Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants. Remove and dispose of infected plants or plant parts. Surrounding plants should also be treated to fully control the problem.
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.
Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Solutions: Each source of scarring requires a different approach to help your plant recover. Protect the trunk and leaves from physical damage like scrapes. If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Aphids
Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.
Overview
Aphids, also known as plant lice, can appear on almost any garden plant. These pests are tear-drop shaped, soft-bodied, and 3 mm or less in size.
Aphids can occur in all seasons, but they reproduce more quickly in warmer weather. Therefore, infestations are likely to become severe in late spring through early fall.
These pests feed on plants including trees, shrubs, vegetables, and flowers. While aphids feed on a large variety of plants, small plants are most susceptible to extreme damage. Aphids are more likely to occur on plants that are unhealthy due to insufficient light, nutrients, or watering problems, plants that have been excessively fertilized with nitrogens, and those that are in shock from pruning or transplanting.
Aphids are easy to control if they are caught early. If not treated early on, populations can quickly grow and cause major damage. In severe cases, entire plants may die.
Symptom Analysis
Aphids are often seen before they have had a chance to do a lot of damage. These insects can be found in clusters under the leaves or on stems. They may be green, brown, white, yellow, or white.
Aphids secrete a sugary substance on plants known as "honeydew." While it is not harmful to the plant, it may be a telltale sign that these pests are present, and if left on the plant it can cause a black fungus known as sooty mold to take hold.
Aphids damage appears as many small dots known as stippling. If the pests are not removed, leaves may turn yellow or die. Leaves and stems may also become twisted.
A large number of ants in the area may also indicate an aphids problem. Ants take care of aphids in order to eat the honeydew that they secrete.
Solutions
Aphids can be controlled with physical, biological, and chemical methods.
For less severe cases:
- Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants.
- Use a hose with a good stream of water to spray them off.
- Introduce beneficial insects such as ladybugs and lacewings.
For severe cases:
- Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants.
- Remove and dispose of infected plants or plant parts.
Surrounding plants should also be treated to fully control the problem.

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.

Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
Scars form when the plant repairs wounds. They can be the result of people or pets passing by and scraping the plant. Once the underlying issue is resolved, the plant will heal but a scar may remain.
Pests and pathogens can also cause scarring. Insects may attack the plant for a meal, resulting in extensive scarring when a few invaders turn into an infestation. Diseases such as fungus and bacteria can weaken the plant, causing brown spots, mushy areas, or blisters that lead to scars.
Scars occur on stems when a leaf or bud has been lost and the plant has healed. The harder tissue is like a scab that protects a wound.
On other occasions, scars can signal problems from environmental conditions, such as overexposure to sunlight or heat. It might surprise you to know that plants can suffer from sunburn, even desert dwellers like cactus!
Solutions
Each source of scarring requires a different approach to help your plant recover.
- Protect the trunk and leaves from physical damage like scrapes.
- If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray.
- Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
- Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
Preventing some sources of scarring is easier than others, but all start with careful attention to your plants once you decide to bring them home.
- Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
- Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
- Once established, check your plants regularly for signs of scarring or the presence of pests, as it is better to catch problems as early as possible.

Prevention
Prevention steps include the following:
- Avoid buying and transplanting plants with any sign of aphids on them.
- Keep gardens weeded and remove debris from around plants.
- Plant a wide diversity of plants to provide food and habitat for beneficial insects that eat aphids. These insects include ladybeetles, lacewings, and minute pirate bugs.
- Avoid using broad-spectrum pesticides that can kill beneficial insects that eat aphids.
- Release beneficial insects such as ladybugs and lacewings to prevent large aphids outbreaks.
- Regularly check for aphids and remove them when they first appear. This is especially important in enclosed areas like greenhouses.
- Apply a balanced fertilizer in the recommended amount to avoid over-fertilizing.

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.
