Why This Fertilizer?
This fertilizer has a nice ratio of the essential nutrients that are great for what a pumpkin needs. While many would not agree, the phosphorus (middle number) is the maximum I would like to see as this has a tendency to accumulate in the soil and can cause ground water contamination. However, at this ratio, and at the rate it is added (next post) the accumulation is kept to a minimum. The increased ratio of potassium is great and why it is added at this point in the growing season. The plant itself does not need much potassium, but the pumpkin is a heavy potassium sink. Since this is a nutrient that can easily leach adding it early in the season should not be the only addition. The pre-plant application is to ensure good baseline soil potassium level, but now when demand increases it should be added. (Again, as part of the soil-hydro concept.)
