In order to cure something, you need to know what caused it in the first place- Blight is actually caused by a colonization of an infectious organism, generally virus, fungi or mold. Plants that have been affected often begin wilting, or the leaves curl, yellow and dry up. Since the plant has been infected with a virus or fungi, it can spread from plant to plant, which in turn causes an entire crop to be infested. The fungal blight is spread from spores that travel through the air.
How to Prevent Blight:
There are a number of steps you can take to prevent blight in the first place, negating the need for treating it altogether.
- Avoid Over watering plants- plants that require low amounts of water will pick up fungal infections rapidly when over-watered
- Avoid Over Crowding- space plants properly to avoid overcrowding. Good airflow helps prevent infections.
- In houseplants, use healthy, clean soil
- Avoid composting plants that have been infected with blight
- Apply Mulch or Straw around the plants to prevent water from splashing up underneath the plant
How to Treat Blight:
If you've done all you can and your garden or houseplants are exhibiting signs of blight, here is a rapid cure. Fill a clean spray bottle with water, add a few drops of DAWN ORIGINAL dishwashing detergent. Not the scented kind, not the colored kind, just the ORIGINAL Blue Kind that you can still buy at the dollar store for 1.00. Seal and shake well to even distribute the dawn throughout the bottle.
For our houseplants we use a 4 oz mini-spray bottle and add 2 DROPS of dawn.
Spritz the affected areas of the plant.
To treat an entire Garden:
1 level tablespoon of baking soda
1 level tablespoon of Epson salts
1 level tablespoon of miracle grow (tomato or veg. fertilizer)
2 tsp of liquid dawn dish soap (reg. blue strength)
3 tablespoons of regular rubbing alcohol
Mix all in one gallon of water, apply to everything in the garden every 10 days.
Did you know?
The Irish potato famine of 1845 was actually caused by Potato Blight.
We have NOT tried ANY other brand of soap, so we cannot tell you whether or not any other brand is effective at treating blight. If you happen to give it a try, we'd love to hear your results.
