Organic Fungicide for vegetables, shrubs and flowering plants
| | |
Posted by dclegg 9a florida (My Page) on Sat, Oct 31, 09 at 10:39
| I live in Central Florida. Everything in my yard has some sort of fungus on it. What can I use that is organic to fight this and bring the plants back. I have read several posts, but not sure what works and what doesn't. I have tried baking soda, veg oil , castile soap and water, but it doesn't seem to improve the conditions. Thanks |

| dclegg: there may be some organics useful to you but you must first determine what the mystery condition is before doing anything. It may be possible that a change in your cultural practices would control the problem such as watering in the morning instead of during the night. Do any of your neighbors have the same problem, see what they know? Are there any garden clubs around to ask? Check the "Florida Gardening" section of Gardenweb. I used to live in your neck of the woods but can't remember having the condition you are describing, perhaps powdery mildew? |

| It is also important to remember that most fungicides, and especially organically derived ones, are preventative rather than curative in method. When applied correctly, they will only help to stop or slow the spread of the disease to unaffected foliage but they won't "fix" what is already infected. If you know you are growing plants prone to these problems, start treating before you see any symptoms. The "best" fungicide is preventing the disease from ever starting :-) Obviously that's not going to be possible in all situations but selecting disease-resistant varieties, limiting the cultural conditions that promote fungal diseases (poor air circulation/over crowding, overhead watering, improper siting, excessive humidity, poor drainage, etc.) and practicing good garden sanitation should go a long way in preventing these problems from ever getting a foothold. |

dc, this is a little experiment I did, might or might not help you, and the results could've been totally random, but:
someone gave me a discarded boxwood bush from a store destined for the trash. I planted it, even tho boxwoods are a little formal for my tastes. It showed signs of possible fungal dx. put a mulch of shredded pau d'arco bark around base. this is something I have plenty of, as I order herbs that I can't grow for medicinal purposes.
The bush is now very healthy-looking.
When I see more fungal problems-another rainy year again?- I'm going to repeat this little experiment and see what the results are. like i said- maybe nothing-but it did make an attractive mulch! |
