Common issues for Common columbine 'Black Barlow' based on 10 million real cases
Sap-sucking insects
Sap-sucking insects Sap-sucking insects
Sap-sucking insects
Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Solutions: Sap-sucking insects can be hard to spot, as they are often small and attach to the undersides of plant leaves. If you see signs of an infestation, follow these steps to eradicate it. Hand-pick bugs and remove eggs: Inspect your plants for insects and drop any you find in a container of soapy water. Look carefully at the undersides of plant leaves and squish any egg clusters you find. Use Insecticide: Targeted spraying can take out sap-sucking insects. Small infestations can be controlled with insecticidal soap, though larger outbreaks might require a stronger spray. Introduce natural predators: Many insects, including ladybugs and praying mantises, love to feast on sap-suckers. You can purchase them at garden stores and release them near infected plants, or encourage wild ones by creating habitat space.
Aged yellow and dry
Aged yellow and dry Aged yellow and dry
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.
Black spot
Black spot Black spot
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Solutions: Some steps to take to address black spot include: Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves. Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash. Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil. Use a spreader in the fungicide spray to ensure better coverage.
Powdery Mildew
Powdery Mildew Powdery Mildew
Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Solutions: As powdery Mildew spores are transported by the wind, it can be tricky to put a complete stop to the spread of the fungus. Luckily, there are several easy treatments for plants that are exhibiting symptoms: If powdery Mildew seems to be impacting isolated leaves or stems, they can simply be trimmed away and disposed of. Disinfect pruning tools after doing this. Remove any plant debris from the ground around the infected plants and dispose of it in the garbage. Then, cover the soil with a thick layer of mulch to limit reinfection. Milk sprays have been found to be useful in controlling powdery Mildew. Make up a spray consisting of 60% water and 40% milk and spray on the affected plants. This can also be used as a preventative measure. In cases where powdery Mildew is more widespread, plants can be sprayed with a mild sulfur- or copper-based fungicide or a non-toxic solution made from baking soda and soap. Sprays can help areas that have been recently infected, though they are less effective against well-established infections. If possible, try transplanting the plants to a sunnier location. Though powdery Mildew does fine in hot, dry conditions, it is unable to reproduce without some humidity. Putting plants in more direct sunlight can help stop the spread of the fungus. Trimming around closely-packed plants can help improve airflow, which also prevents the reproduction of the fungus.

Sap-sucking insects can create dense clusters of small yellow or white spots on the leaves.
Symptom Analysis
Symptom Analysis
Your plant has developed tiny yellowish spots scattered across the leaves that look like mold or mildew. If these marks won't wipe off, they are likely caused by sap-sucking insects like aphids, squash bugs, scale bugs, leafhoppers, whiteflies, mites, mealybugs, and more.
Each of these pests uses mouthparts to pierce leaf tissues and suck the sap. uses mouthparts to pierce leaf tissues and suck the sap. Signs of damage are difficult to spot at first, but a large infestation can quickly compromise the whole plant. You're most likely to see sap-sucking insects during the hottest months because plants make easier targets when already weakened from heat or drought.
Though sap-sucking insects are unlikely to kill your plant on their own, they can severely weaken it and make it more susceptible to disease. They may also spread viruses from one plant to another as they feed.

Prevention
Healthy plants are less likely to suffer from sap-sucker attacks. Keep them fortified with fertilizer and the right amounts of water and sunlight. Plants that receive excess nitrogen are also more susceptible to attack, so don’t overfertilize. You should also remove weeds and tall grasses surrounding your outdoor plants so as not to create habitat space for the pests.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
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
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
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.

Black spot
plant poor
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Overview
Overview
Black spot is a fungus that largely attacks leaves on a variety of ornamental plants, leaving them covered in dark spots ringed with yellow, and eventually killing them. The fungus is often simply unsightly, but if it infects the whole plant it can interfere with photosynthesis by killing too many leaves. Because of this, it is important to be aware of the best methods for preventing and treating this diseases should it occur in the garden.
Symptom Analysis
Symptom Analysis
Here are a few of the most common symptoms of black spot:
  • The plant has developed small black spots along the leaves.
  • These spots be small, circular, and clustered together, or they may have a splotchy appearance and take up large portions of the leaves.
  • The fungus may also affect plant canes, where lesions start purple and then turn black.
  • The plant may suffer premature leaf drop.
Though most forms of black spot fungus pose little risk to a plant's overall health, many gardeners find them unsightly. Severe cases can also weaken a plant, so it becomes more susceptible to other pathogens and diseases.
Disease Cause
Disease Cause
Black spot is spread by various types of fungi, which differ slightly depending on whether they are in their sexual or asexual stages.
The fungal spores linger over the winter in fallen leaves and lesions on canes. In the spring, the spores are splashed up onto the leaves, causing infection within seven hours of moisture and when temperatures range between 24 to 29 ℃ with a high relative humidity.
In just two weeks, thousands of additional spores are produced, making it easy for the disease to infect nearby healthy plants as well.
There are several factors that could make a plant more likely to suffer a black spot infection. Here are some of the most common:
  • Exposure to infected plants or mulch (the fungus overwinters on dead leaves)
  • Weakening from physical damage, pest infestation or other infections.
  • Increased periods of wet, humid, warm weather – or exposure to overhead watering
  • Plants growing too close together

Powdery Mildew
Powdery mildew is a white mold that appears on leaves. It can be wiped away.
Overview
Overview
Powdery Mildew is a common disease and the scourge of many home gardeners. It affects a large variety of plants including many varieties of vegetables. The disease is easy to identify but not always easy to get rid of once it has started to infect plants.
Powdery Mildew thrives in warm, humid conditions and can quickly spread from plant to plant. Although this disease will not kill the plants, a severe infestation will inhibit plant growth and fruit production.
Symptom Analysis
Symptom Analysis
Powdery Mildew appears as pale yellow spots on leaves. These spots then become white and look powdery. The fungus spreads quickly both on the top and underside of the leaves and on the plant stems.
These white, powdery spots will join up and soon, almost the entire surface of the leaf appears white. Eventually, the edges of the leaf will turn brown and dry and start to die.
In severe infections, even the flower buds will turn white and become disfigured. Fruit will ripen prematurely and be inedible.
Disease Cause
Disease Cause
Powdery Mildew is caused by a fungus. There are many different genera of fungus diseases that cause powdery Mildew. The fungal spores overwinter inside leaf buds and on plant material that has dropped to the soil below. As the weather warms up, these spores are then carried onto the plant by water, wind, and insects. Powdery Mildew can also be more severe in areas that experience warm, dry climates, even though the spores require some humidity to germinate.

  • Rake and discard fallen leaves in the fall.
  • Prune regularly.
  • Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback. Adding a layer of mulch to the soil will also reduce splashing.
  • Grow plants in an open, sunny locations so the foliage dries quickly.
  • Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation.
  • Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.

  2. When placing new plants, allow enough space between each one to provide adequate air circulation.
  3. Water at the base of plants rather than from overhead.
  4. Many mildew-resistant strains of common garden plants are available. Consider these in areas that have a Mediterranean climate.
  5. Powdery Mildew can form tiny, round black structures, called cleistothecia, as the growing season draws to a close. These hardy, dry structures help the fungus survive winter. Raking away debris over the winter can remove stowaway cleistothecia and will help prevent plants from being reinfected.
