Weather Conditions: All plant material was planted in full sun. All material is watered three times a week (unless it rains) for 15 minutes and is fertilized every other week with 21-7-7 at 400ppm Nitrogen. Annual material is planted from a 4″ container in a block of nine. Perennial material is planted from a 1-gallon container in a block of one to three (depending quantity of plants that we receive).
As usual we had a hot summer. There was a recorded fourteen days in a row over 100 degrees. We did have quite a bit of rain fall that helped cool us off a bit, after the rains high percentages of humidity followed. Overall it was a hot and sticky summer.
