How do I recognise powdery mildew on a plant?

Powdery mildew (or white mildew disease) shows up as a powdery white deposit on the leaves, stems and buds, as if flour had been sprinkled over them. The affected leaves turn yellow, become distorted and eventually fall. It often appears when heat alternates with humidity.

How do I treat powdery mildew naturally?

Several natural remedies are effective: diluted bicarbonate of soda (1 teaspoon per litre of water + black soap), milk diluted to 50% (weekly spray), sulphur powder or neem oil. Remove the affected parts first before treating.

Is powdery mildew contagious to other plants?

Yes, powdery mildew is very contagious. Its spores are spread by air, water and tools. Isolate the affected plant straight away, disinfect your tools after use, and avoid wetting the leaves when watering to limit the spread.

How do I prevent powdery mildew?

Good ventilation around the plants, avoid excess humidity and watering over the leaves, prune regularly to let air through, treat preventively with horsetail extract (rich in silica, which strengthens cell walls), and choose resistant varieties.

Introduction

Have you noticed a strange white deposit on your plants' leaves? As if someone had spilled flour or talcum powder? It isn't dust. It's powdery mildew, also called “white mildew disease”.

It is a very common fungal disease (a fungus) that smothers the plant, distorts the leaves and can ruin a flowering or a harvest.

Don't panic! Impressive as it looks, powdery mildew is very treatable, especially if you act fast with the right natural solutions. Here is the Jungle Feed plan of attack.

1. Identification: Is It Really Powdery Mildew?

The diagnosis is fairly simple because the symptoms are characteristic:

The white “powder”: This is sign no. 1. A white or greyish felt-like coating appears on the upper side of the leaves, on the stems and sometimes on the flower buds.
It wipes off (at first): If you run a finger over it, the powder comes off, leaving the leaf slightly damaged underneath.
The distortion: If left alone, the leaves curl up, buckle, turn yellow and eventually dry out.

Powdery mildew's favourite victims:

Indoors: Begonias, Kalanchoes, African violets (Saintpaulias), Crotons.
On the balcony/in the garden: Roses (the champions!), tomatoes, courgettes, grapevines, strawberries.

2. Why Me? The Causes

This fungus doesn't turn up by chance. It takes advantage of specific conditions:

Temperature swings: Warm days followed by cool, damp nights (typical of spring and autumn).
Stagnant air: Indoors, plants packed too closely together stop the air circulating, creating a humid microclimate the fungus loves.
Watering the foliage: Wetting the leaves, especially in the evening, is an open invitation to the disease.

3. The Natural Plan of Attack (Curative)

Powdery mildew is here? Get out your “Natural Medicine Cabinet”.

Step 1: Surgical Pruning

Don't try to “clean” the worst-affected leaves (the ones that are completely white). Cut them off.

Use disinfected Precision Shears.
Put the waste in the bin (definitely not on the compost heap, or you'll contaminate the whole garden!).

Step 2: The Shock Treatment (The “Antibiotic”)

This is where our new product comes in. Garlic Fermented Extract is a formidable natural fungicide thanks to its sulphur content.

Action: Spray generously over the whole plant (upper and lower sides of the leaves).
Frequency: Every 3-4 days until all traces of white have completely disappeared.

Step 3: The Cleaning (Optional but Recommended)

If the plant is sticky or dirty, give it a first pass with Black Soap before treating. This will “wash” the surface spores away.

4. Prevention (So It Doesn't Come Back)

Once the disease has gone, you need to stop it returning by strengthening the plant.

The secret: silica. Use Horsetail Fermented Extract as a spray every 15 days. Rich in silica, it thickens the skin of the leaves. The fungus can no longer pierce the leaf to settle in. It's a real shield.
Good practices:
1. Space your plants out so the air can circulate.
2. Always water at the base, never over the leaves (use a Long-spout watering can).
3. Check the undersides of the leaves regularly.

Summary: The Anti-Powdery-Mildew Kit

THE DIAGNOSIS: White powder on the leaves + leaves that buckle.

THE CAUSE: Stagnant humidity + temperature swings.

THE TREATMENT (Curative):

Cut off the dead parts.

Treat with Garlic Fermented Extract (powerful fungicide).
