Fertilizers and micro-nutrients play a big role in the growth and health of your plant, as well as the development and growth of flowers and fruit. Each element aids the plant in some aspect and in different ways. And when it comes to promoting blooms for all kinds of flowering plants, phosphorous fertilizer is your number one tool.
In the plant world, the major role of phosphorous, is during the flowering and fruit set stage. It promotes flowers in all plants. The production of pumpkin flowers are no exception.
After your pumpkin vines have grown several feet in length, it’s time to ease back on the nitrogen and use a fertilizer high in phosphorous. Even if your plant has begun to produce flowers, you should apply a high-phosphorous fertilizer. Your plants will respond by producing even more flowers, The proliferation of both male and female flowers increases the likelihood of pollination. Now, I don’t know of anyone who will complain if they get more pumpkins on the vine.
Important tip: Too much nitrogen in the soil can delay the onset of flowers and fruit set.
