Diseases can completely destroy your plants, so it’s essential you make yourself aware of the different types of plant diseases that may impact the species in your garden. Powdery mildew is one such problem, that’s relatively common amongst hedge plants. Although the fungus is not fatal, it can affect your plant’s growth so is best to be eliminated.
We’ll discuss what powdery mildew is, how to treat powdery mildew and how to prevent it below.
Powdery mildew is a common fungal disease that can affect many plants, including basket grass. It appears as white powdery spots on leaves, stems and flowers. While not fatal, powdery mildew can weaken plants and affect their appearance. If left untreated, it can lead to reduced photosynthesis, poor growth, and make plants more susceptible to other problems. Fortunately, powdery mildew can be controlled and prevented with some simple organic solutions.
Understanding Powdery Mildew
Powdery mildew is caused by various fungal species in the order Erysiphales. It thrives in warm, humid environments with poor air circulation. The disease spreads through windblown spores that land on plant surfaces and germinate. As the fungus grows, it sends root-like structures into the plant’s epidermal cells to extract nutrition. This leads to the characteristic white powdery patches.
On basket grass powdery mildew typically appears first on older leaves. Once established, it can spread rapidly to all above-ground parts of the plant. Infected leaves turn yellow and dieback occurs. Repeated infection weakens the plant over time.
Powdery mildew spores easily spread the disease to nearby plants Thorough sanitation and preventative measures are needed to control outbreaks.
Organic Treatment Methods
Milk Spray
One of the simplest organic treatments for powdery mildew is a spray made from 1 part milk mixed with 9 parts water The milk proteins interact with sunlight to inhibit fungal spore growth
To treat basket grass, thoroughly coat all leaf surfaces with the milk solution on a sunny day. Reapply every 5-7 days to protect new growth. Use only fresh whole milk for best results.
Baking Soda Spray
Baking soda has natural antifungal abilities that can combat powdery mildew. Mix 1-2 teaspoons baking soda per 1 quart (1 l) of water. Add 1 teaspoon vegetable oil as an emulsifier. Spray plants every 7-10 days until mildew is under control.
The baking soda changes the pH on leaf surfaces to prevent fungal growth and spore germination. Repeat applications may be needed to fully eradicate mildew.
Neem Oil
Neem oil is extracted from the neem tree and has antifungal, antibacterial and anti-inflammatory properties. It disrupts the fungal life cycle and prevents spore formation.
Mix neem oil as directed on the label and thoroughly coat basket grass leaves. Reapply every 7-14 days. Neem oil also helps strengthen the plant against reinfection.
Potassium Bicarbonate
This simple baking powder ingredient kills powdery mildew spores on contact. Dissolve 1-2 teaspoons potassium bicarbonate per 1 quart (1 l) of water and add a small amount of liquid soap. Completely cover leaves and stems with this solution. Reapply every 7-10 days.
Preventing Recurrence
Once you’ve treated active powdery mildew, consistent prevention is key to avoiding recurrence:
- Isolate infected plants until treated
- Improve air circulation and light conditions
- Water at the base of plants to minimize leaf wetness
- Apply preventative sprays weekly
- Remove and destroy severely infected foliage
- Clean tools and garden debris to reduce spore spread
- Plant resistant varieties when possible
With vigilance and proper care, powdery mildew can be controlled in basket grass plantings. Be sure to remove and destroy any infected plant parts. Consistent applications of organic treatments will help create an environment unfavorable for fungal growth. Your diligence will be rewarded with healthy, flourishing basket grass plants.
What is Powdery Mildew?
Powdery Mildew is a white fungus that attacks many species of plants. It is extremely common in most plant species and easily recognisable by the growth of white fungus on the leaf of the plant. The growth also extends to a plant’s stems and flowers.
Plenty of species are affected by Powdery Mildew, the most common being roses, grapes, cucumbers, grasses, azaleas, rhododendrons, daisies and more.
The fungus prefers warm and dry environments, appearing as white or grey spots on your plant or hedge. Whilst this does not kill the plant, it is not aesthetically pleasing which can be an issue for many gardeners. When left to grow however it can leech the nutrients from the plant which can cause stunted growth. Therefore, it is best to get rid of powdery mildew where possible.
Is Powdery Mildew Harmful to Humans
Whilst this fungus has no direct negative effects on humans (including human contact), it can cause problems for many people who are allergic to this particular mould or suffer breathing problems.
If you touch or consume the plant and you’re allergic you could have a serious reaction. Again, when inhaled consistently it can cause problems for those who are vulnerable, such as asthmatics for instance.
