Disease / Pest	Severity	Symptoms	Cause
Spider Mites	Medium	Spider mites on Arenaria montana cause stippling, which appears as tiny yellow or white speckles on the surface of leaves, indicating that the mites have been feeding on the plant's cells. As the infestation worsens, the leaves may turn bronze or yellowish and may eventually dry out and drop. A characteristic sign is the presence of fine, silken webbing, often found on the undersides of leaves, along stems, and in new growth. These mites are very small and can be difficult to see with the naked eye, but their webbing is typically a good indicator of their presence. The plant will often appear generally unhealthy and less vigorous.	Spider mites are tiny arachnids that thrive in hot, dry, and dusty conditions. They are commonly introduced to houseplants through contaminated soil, new plants, or even by being carried in on clothing or pets. Low humidity is a major contributing factor to spider mite infestations, as they prefer dry environments. Stressed plants, due to underwatering or poor nutrient availability, are also more susceptible to attack.
Leaf Spot	Medium	Leaf spot diseases on Arenaria montana typically appear as small, circular or irregular spots on the leaves, which can range in color from brown to black, sometimes with a yellow halo. These spots may start small and gradually enlarge, potentially coalescing to form larger, blighted areas. Severely affected leaves can become yellowed, distorted, and eventually shrivel and drop from the plant. The disease can spread rapidly, especially in humid conditions, and can significantly reduce the aesthetic appeal and health of the plant by photosynthetically active leaf area reduction. In advanced stages, the entire leaf surface might be covered by lesions.	Leaf spot diseases are typically caused by fungal or bacterial pathogens. These microorganisms thrive in conditions of high humidity, poor air circulation, and wet foliage. Spores or bacteria can be spread by splashing water, wind, or contaminated gardening tools. Overwatering, insufficient light, and plant stress can make Arenaria montana more susceptible to leaf spot infections.
Powdery Mildew	Medium	Powdery mildew on Arenaria montana typically manifests as a white, powdery or mealy-like growth on the surface of leaves, stems, and sometimes flowers. This fungal growth is often distinct and can cover large areas of the plant. Affected leaves may become distorted, yellowed, or develop brown spots beneath the powdery coating. In severe cases, the leaves can dry out, curl, and drop prematurelly. The disease thrives in conditions with high humidity and moderate temperatures, and it can significantly affect the plant's ability to photosynthesize, leading to reduced vigor and potentially death if left untreated. The characteristic white coating can be easily wiped off in early stages, but becomes more persistent over time.	Powdery mildew is caused by various species of fungi, primarily in the order Erysiphales. These fungi reproduce rapidly in conditions with high humidity, moderate temperatures, and limited air circulation. They are obligate parasites, meaning they require a living host to survive. Spores are spread by wind, water, or contact with infected material. Plants that are stressed due to overwatering, poor light, or nutrient deficiencies are more susceptible.
Mealybugs	Medium	Mealybugs on Arenaria montana appear as small, white, cottony masses clinging to the undersides of leaves, stems, and in the crevices where leaves meet the stem. These soft-bodied insects feed on plant sap, weakening the plant and causing stunted growth. Infested areas may become sticky due to the honeydew they excrete, which can also lead to the development of a black sooty mold. Severe infestations can cause leaves to turn yellow, curl, or drop off, and can ultimately lead to the death of the plant if left untreated. They are often found in sheltered areas of the plant, making them harder to spot initially.	Mealybugs are tiny, sap-sucking insects that are attracted to plants with stressed conditions, poor air circulation, or existing damage. They reproduce rapidly and can be introduced to your Arenaria montana through infested new plants, tools, or even carried by wind. Their cottony appearance is a protective wax coating that helps them retain moisture and deter predators, making them resilient to environmental changes once established.
Root Rot	High	Symptoms of root rot in Arenaria montana typically begin with a general decline in plant health. Leaves may turn yellow and wilt, even if the soil appears moist. Stunted growth is common, and the plant may seem to be struggling despite adequate watering. Upon closer inspection or if the plant dies, the roots will appear dark brown or black, mushy, and foul-smelling, indicating fungal or bacterial infection. The crown of the plant where the roots meet the stem may also show signs of decay. In severe cases, the entire root system can disintegrate, leading to the plant's collapse and death.	Root rot is primarily caused by waterlogged soil conditions, often due to overwatering or poor drainage. Fungi such as Phytophthora, Pythium, and Rhizoctonia, or bacteria, thrive in these anaerobic environments and attack the plant's roots. High humidity, insufficient light, and poor air circulation can exacerbate the problem, creating an ideal breeding ground for pathogens. Damaged roots from transplanting or other stress can also become entry points for infection.

Disease / Pest	Solution	Prevention	Treatment
Spider Mites	For spider mite infestations on Arenaria montana, it is crucial to increase humidity around the plant, as they dislike moisture. Wash the plant thoroughly with a strong stream of water to dislodge as many mites as possible. Then, spray the foliage with insecticidal soap or neem oil, ensuring to cover the undersides of leaves where mites often hide. Repeat treatments every 3-5 days for at least two weeks to break the mite's life cycle. Acaricides (miticides) can also be used for severe infestations, following product instructions carefully. Regularly clean surrounding areas to remove dust.	Maintain adequate humidity levels around your Arenaria montana, especially during dry periods, by misting the plant regularly or placing it near a humidifier or pebble tray filled with water. Avoid letting the plant dry out completely, as this stresses it and makes it more susceptible to mites. Inspect plants regularly for signs of webbing or stippling. Isolate any new plants before introducing them to your collection. Keeping the plant clean and free of dust will also help deter spider mites.	Monterey Insecticidal Soap
Leaf Spot	Remove and destroy any affected leaves immediately to prevent further spread. Avoid overhead watering; water the plant at the base, preferably in the morning, to allow foliage to dry quickly. Improve air circulation around the plant by spacing plants adequately or using a fan. In cases of persistent or severe outbreaks, a fungicide spray, such as one containing copper or chlorothalonil, may be necessary. Always follow the product label instructions carefully. Ensure the plant is receiving adequate light and nutrients.	Provide good air circulation and avoid overhead watering. Water only when the top layer of soil is dry. Remove any fallen leaves or debris from around the base of the plant, as these can harbor pathogens. If an outbreak occurs, sanitize gardening tools after use. Ensure the plant is healthy and vigorous by providing proper light, water, and nutrition, as healthy plants are more resistant to diseases. Quarantining new plants is also a good preventative measure.	Spectracide Copper Fungicide Spray
Powdery Mildew	Remove and destroy any infected leaves or plant parts immediately. Improve air circulation by spacing plants appropriately or using a fan. Avoid overhead watering, as water on foliage can encourage fungal growth; water at the base of the plant in the morning. Apply a fungicide spray specifically formulated for powdery mildew. Options include sulfur-based fungicides, potassium bicarbonate solutions, or commercial fungicides. Repeat applications as directed by the product label, usually every 7-14 days, until the infection is controlled. Ensure consistent conditions for your plant.	Provide good air circulation around your Arenaria montana and avoid overcrowding. Water the plant at the base and avoid wetting the foliage, especially in the evening. Ensure the plant receives adequate light and is not under undue stress. Remove any declining or dead plant material from around the plant. When planting, choose a location with good airflow. Consider using a preventative fungicide spray during periods of high risk, such as during humid weather.	Captain Jack's Dead Bug Brew (contains Spinosad for some fungal issues)
Mealybugs	For light infestations, manually remove mealybugs with a cotton swab dipped in rubbing alcohol. For heavier infestations, spray the plant with insecticidal soap or neem oil, ensuring thorough coverage, especially on the undersides of leaves and in stem crevices. Repeat treatments every 7-10 days until the infestation is cleared. In severe cases, consider using systemic insecticides, but always follow label instructions carefully. Improve air circulation and remove any dead or decaying plant material, as this can harbor pests.	Regularly inspect your Arenaria montana, especially the undersides of leaves and stem junctions, for any signs of white, cottony masses. Quarantine new plants for at least two weeks before introducing them to your collection to ensure they are pest-free. Maintain good air circulation around your plants and avoid overcrowding. Promptly remove any dead leaves or debris, as these can provide hiding places for pests. If you notice even a few mealybugs, deal with them immediately to prevent a large infestation.	Neem Oil Concentrate
Root Rot	Immediately remove the affected plant from its pot. Carefully inspect the root system, pruning away any dark, mushy, or foul-smelling roots with sterile scissors. Repot the Arenaria montana in fresh, well-draining potting mix, ensuring the pot has adequate drainage holes. Consider using a fungicide drench specifically formulated for root rot to treat the remaining healthy roots and prevent reinfection. Allow the soil to dry slightly between waterings, and ensure good air circulation around the plant. If the root rot is severe and most roots are compromised, it may be necessary to propagate healthy cuttings from the plant if possible, as the original plant may not recover.	The key to preventing root rot in Arenaria montana is proper watering and good drainage. Use a well-draining potting mix formulated for succulents or cacti, or amend standard potting soil with perlite or sand. Ensure pots have drainage holes and avoid letting the plant sit in standing water. Water only when the top inch or two of soil feels dry to the touch, and reduce watering frequency during cooler months or when the plant is dormant. Good air circulation around the plant and adequate light will also help promote healthy growth and reduce the risk of fungal diseases. Inspect new plants for signs of disease before introducing them to your collection.	Dr. Earth Root Zone
