Initially, you can fertilize your pumpkins with a fertilizer having NPK 10-5-5 ratio as nitrogen boosts pumpkins growth. Then when the flower starts to form, switch to a fertilizer with much phosphorus percentage. It will help with plentiful blossoms. And once the fruit comes out, apply fertilizer with high potassium percentage as it will help to grow healthy food.

When to Fertilize Pumpkins?

Fertilizers are very important for pumpkins. Ideally, there are two types of flower available in pumpkin plants, male and female. The male flower appears before females during July or later. Each of them needs different types of feeding. But fertilizing your pumpkins always depends on your soil condition. Although you can fertilize your land by dividing the whole season into three parts: seeding stage, flowering stage, and fruiting stage.

  1. Seeding: You should prepare your land first. Once seeding is done and new leaves come out, apply fertilizer with a high nitrogen percentage. Nitrogen will help your plants to grow fast. As pumpkins love Sun, May or June can be the best time for seeding.
  2. Flowering Stage: Pumpkin flower has two types, male and female. Male comes first usually during July or later, then comes female. It is good to use fertilizers with a high phosphorus rate as this will help flowers to grow plenty and healthy.
  3. Fruiting Stage: When the fruit starts to come, you should apply fertilizers with a high potassium rate. This helps fruits to grow healthy and robust. Do not over-fertilize your land during this time. You can use compost every two weeks to give them an extra boost.

How Often Do You Need to Fertilize Pumpkins?

Fertilizing your land completely depends on soil and plant’s need. A good and healthy pumpkin requires a good seed, best fertilizer and proper nurturing. Generally, it is enough to fertilize pumpkins once in every two weeks. But depending on every stage of pumpkins, fertilizers should be different. It is good to use organic fertilizers over synthetic as they cause no harm even on over-use. Do not over-fertilizer your land to get more production. Keep a balance among your fertilizers and maintain a cycle during fertilization.

Other Things You Should Keep in Mind

Watering: Watering your land is the most important to get a robust pumpkin. Since pumpkin is a sun-loving plant, it requires enough water to grow healthy and strong.

Location Choosing: Pumpkin plants love the sun and they need a lot of it. So, you should choose your location by keeping this information in mind. You should choose an open and sunny area to get proper pumpkins.

Weed Removal: Weed removing is necessary as they will try to consume the water from pumpkin plants. You should keep your plants clean.
