Watermelon Weight Factors

Here are the factors that affect how much a watermelon weighs at maturity, as it goes through it’s growing stages:

Nutrients and Maturation

Watermelons will grow larger if they are fertilized or fed organic nutrients. This is good if you’re trying to grow a giant watermelon to win a growing contest. However, if you plan to eat your watermelon, it’s not a good idea to use too much chemical fertilizer. This can affect the taste and health-giving benefits of the fruit.

Watermelons should be allowed to grow to their full potential and left to ripen on the vine. The plants also need to be watered regularly to produce juicy fruits. Watermelons that are well cared for and watered are more likely to grow to a bigger size and weigh more. If you pick your watermelon before it’s ripened, it will likely be smaller and weigh less. Picking the fruit too soon may also affect the taste and juiciness of the fruit.
