| We just moved into a house and there's a lovely crabapple tree out back that has fungal leaf spot. Any effective non-chemical remedies out there? If so, when and how [often] do I treat? |
| Fungal leaf spot? Cedar apple rust? |
| You can spray whole milk at a 1 part milk with 4 parts water. |
| I use a baking soda and water solution with a little dish soap in a spray bottle |
| Copper Spray....100% organic and works very well. |
| Copper builds up in the soil, though. |
