When it starts to warm up and there is moisture in the air, blossoms are very susceptible to a fungus called Brown Rot. All the work the bees do in the spring will be in vain if the blossoms are not taken care of.
To prevent Brown Rot from destroying all the tree's blossoms, we apply one of the three certified organic materials right to the blossoms. These products could possibly be used in a home garden but attention to correct dosage is critical so that disease control is achieved and no harm is done to the plant. The materials used are Oxidate, Sulfur, and Serenade. Oxidate is a brand name product for a form of hydrogen peroxide. Sulfur is a natural compound that is mined from the earth. Serenade is a strain of the bacteria called Bacillus Subtills.
Frost is another threat to blossoms. Although the weather is getting warm and everyone is thinking about getting out the swimsuit, frost can still be a real danger to blossoms and fruitlets that are already forming inside the blossoms. Farmers will be on the watch for frost if there hasn't been any rain and things are dry. Moisture can retain heat but if things are dry, frost can sneak up without warning in the middle of the night. At times like this we are prepared to turn on the irrigation water. Just the little bit of warmth from the water can save our crop.
Every bit of heat helps. At this time of year we don't cultivate our fields because cultivating will stop the dirt from retaining heat.
