Branch wilt
Hendersonula tortuloidea
What is Branch wilt (Neoscytalidium dimidiatum)?
Branch wilt, caused by the fungus Neoscytalidium dimidiatum previously known as Hendersonula toruloidea affects English walnut and various other plants. It primarily occurs in the interior valley of California, with a limited presence in coastal areas. Symptoms include yellowing and withering of leaves on outer branches, followed by sudden withering, browning, and dryness of leaves on larger limbs. Blighted fruit can also be affected. Diseased branches exhibit gray to dark brown discoloration extending into the wood. Almonds, apples, apricot, chestnut, citrus, fig, peach, poplar, grape, and black walnut are among other plants susceptible to this fungal infection.
How does Branch wilt (Neoscytalidium dimidiatum) occur?
Branch wilt, caused by Neoscytalidium dimidiatum reproduces through tiny fungal spores called arthrospores. These spores are carried by rain and wind. When they find openings in branches, like splits or injuries, they enter the tree. Inside, the fungus grows and causes leaves to turn yellow, wither, and become brown. It also changes the color of the wood. The disease can spread to other plants, causing similar wilt symptoms. Infected fruit can also hold the fungus.
Symptoms
1 - Impacts on Plants and Soil
• Branch wilt caused by Neoscytalidium dimidiatum affects various plant species, causing wilting, yellowing, and browning of leaves. • The presence of Neoscytalidium dimidiatum can potentially alter soil health and nutrient availability. • Branch wilt can impact the overall biodiversity and health of ecosystems.
Solutions
1 - Prevention
• Select disease-resistant plant varieties when available. • Practice good sanitation by removing and destroying infected plant material. • Avoid pruning during wet weather to minimize the risk of spreading the disease. • Implement proper irrigation practices to prevent stress and sunburn on plants. • Promote overall plant health through proper fertilization and pest control.
2 - Treatment
• Prune infected branches, cut back to healthy wood, and remove at least two inches beyond the lower canker. • Apply appropriate fungicides as recommended by local agricultural extension services or experts. Common options include azoxystrobin, propiconazole, thiophanate-methyl, myclobutanil, mancozeb, and copper-based fungicides. • Treat wounds on branches with protective sealants to prevent further infection. • Monitor and manage other potential factors that weaken plants, such as pests or nutrient deficiencies.

FAQ
Do shade growing plants need any Sunlight?
Shade growing plants do need sunlight, although they require less than other plants. They need some direct sunlight each morning to help them photosynthesize and grow properly. Also, indirect sunlight throughout the day helps them stay healthy. Shade growing plants will benefit from the sunshine, but if they get too much or too little, then they can suffer the consequences. It's important to pay attention to the needs of your plants so that you can provide them with the proper light for optimal growth.
How often should you water indoor plants?
Indoor plants should be watered when the soil feels dry to a depth of about two inches, usually about once a week. A helpful technique to determine your plants' watering needs is to feel the soil before and after watering to get a sense of how long it takes to dry out. An important note to remember is that some plants require less water than others, and it's best to research the specific needs of your individual plants. Likewise, if your home is very dry, you might need to water more often as the lack of moisture can stress the plants and lead to problems like brown leaves and wilted stems.
Can my monstera plant get root rot?
Yes, a plant can get root rot. Root rot is a fungal disease that can be caused by over-watering, poor soil drainage, or high humidity levels in the air. Signs of root rot include yellowing leaves, wilting and stunted growth, and damaged or browning root systems. Sometimes it is difficult to detect root rot until the plant is removed from the soil, as the problems are mainly below the soil surface. Treating root rot usually involves removing the affected parts of the plant and replanting the unaffected ones.
Can I put my Monstera outside in summer?
No, you should not put your Monstera outside in summer. Monstera plants need warm, humid air to thrive, and direct sunlight can scorch their leaves. Instead, put your Monstera in a bright, sunny spot with indirect light, making sure the sun never directly hits the leaves. During the summer, keep your Monstera's soil damp and mist it occasionally to keep the leaves hydrated. At nighttime, keep the temperature around 16 - 21°C (60 - 70°F). You can definitely take your Monstera outdoors for short periods of time, just make sure to bring it back in if it starts to get too hot.
What happens if my monstera plant gets too cold?
If your monstera plant gets too cold, it will become vulnerable to pests, disease, or other damage. Cold temperatures can damage the leaves of the plant, causing them to become spotted or limp. The roots of monstera plants may also suffer in cold temperatures, leading to root rot or other diseases. Belonging to the tropical family, monsteras are used to warm environments and do not do well in cold temperatures, so it is important to ensure your plant is kept in conditions that suit their needs.
Is it possible to grow a vegetable garden in a small space?
Yes, it is possible to grow a vegetable garden in a small space. Gardening in a small space can be as simple as growing a few containerized plants in pots and raised beds, or as elaborate as vertically stacking planters, hanging pouches, and hanging baskets on a wall, railing, or fence. Regardless of the size of the space you are working with, some simple techniques such as companion planting, organic fertilizers, and water conservation can help you get the most out of your small vegetable garden.
Is peppermint herb green good for digestion?
Peppermint herb is indeed beneficial for digestion. The flavonoids in the herb support digestion by reducing inflammation in the digestive track, aiding in digestion and relieving indigestion, heartburn, and even the symptoms of irritable bowel syndrome. Additionally, peppermint is naturally rich in menthol, which helps to relax the muscles of the stomach, aiding in the digestion of food. Peppermint herb can be consumed in a variety of forms, such as teas, tinctures and capsules, as well as by adding the herb to food or directly to water or tea.
Should peppermint herb green be consumed daily?
No, peppermint herb green should not be consumed daily. This is because it contains high levels of menthol, which can be toxic if taken in large doses. Additionally, consuming large amounts of peppermint herb green could interfere with the absorption of essential minerals and vitamins, potentially causing vitamin deficiencies. For these reasons, it is best to consult with a doctor before incorporating peppermint herb green into your daily diet.
