It is annual planting season again. We always wait until after Mother's Day to plant annuals, hoping to escape the threat of frost. This year, just like last, we had a late frost. Last year it was May 13 - we got down to 31 degrees. This morning we had a heavy frost again, causing us to take precautions to protect the annuals that were already planted.
Trash bags are helping hold the heat it, fighting off the frost.
In areas where we had irrigation, we just rain the water. The warm water also keeps the frost off.
