It is definitely a power booster. They promise a large supply of big pumpkins while posing the question of pushing versus encouraging the natural process. They also are exquisitely designed to draw nourishment from the sun and guide water to the base of the plant. The question is not whether to water pumpkins, but when and how much. A major factor is the kind of soil in the patch.
Sandy soil needs more water than soil with high deposits of clay.
It is best to water the plant at the roots rather than sprinkling from above. Drip systems and soaker hoses are efficient, reasonably priced, and easy to install. After three true leaves are established, the pumpkin plant moves into wild and crazy leaf and root development that lasts about eight weeks. Ten weeks after planting, the first flowers suddenly appear between leaves and tendrils. Each flower blooms for only one day.
