Like beans, pumpkins also come in many varieties based on what color and size you want your pumpkin to be at. No matter the size though each pumpkin is going to take between 3 to 4 months to reach full size. The main thing to keep in mind when growing them is that you shouldn't be using pesticides. Pumpkins require pollination from bees or other insects so using any kind of anti-insect poison is also going to stop the flowers from being pollinated.
One of the best parts about growing zucchini is that they grow anywhere, doesn't matter if you have them in a pot or directly in the ground. All they need is water and direct sunlight. In fact, they do better in the heat so it's a good idea to plant them in late summer since the seeds will sprout much more easily if the soil is warm. After that make sure to water early in the day so that by the time the sun is at its highest the aboveground parts will be dry and ready to soak in those rays.
