How to Grow Watermelons in Gaines, Michigan, United States of America

Scientist cannot agree as to the exact location of where the watermelon originated, but they all agree that it originated on the African continent. The watermelon is estimated to have crossed from Africa to the Middle East and from there to Europe around the 10th century. There is evidence proving that watermelon was eaten almost 5000 years ago in Libya. Watermelon remains were also found in ancient Egyptian tombs which existed around 4000 years ago. But the first watermelons were not the sweet, tasty luscious-red that we eat today. They were a wild version of the watermelon which was not appetizing and not tasty and definitely not red. So why did they grow and cultivate watermelons 4000 years ago if they were not tasty or appetizing? Harry Paris, a horticulturalist at the Agricultural Research Organization in Israel, believes that the answer to that question lies in the name watermelon – water! He believes that watermelons were cultivated because they are mostly comprised of water and store in cool places for long periods of time. These watermelons were carried onto long journeys as water providers, serving as a natural canteen, which also explains how they travelled from the different continents. This is a fascinating must read article about the history of the watermelon http://news.nationalgeographic.com/2015/08/150821-watermelon-fruit-history-agriculture/ The watermelon arrived to the United States by European colonists and through the slave trade from Africa. In the mid 1800’s the watermelon was so popular in parts of the United States that farmers needed to aggressively protect them from pillagers.

Use these images to know if your watermelon is heading in the right direction and growing properly. Exact number of growing days varies for each watermelon variety. Below is the average number of days for each stage gathered from many different varieties.

Watermelon Germination Guide

(Stage 1: Germination)

Germination is the process by which a plant grows from a seed. It is the first stage of the plant growing process and it begins when the seed is sown and ends when the radicale emerges out of the seed.

All seeds require proper soil temperature, moisture, air and light conditions to germinate successfully. However, during the germination stage the seeds require more soil warmth and moisture than light exposure.

Seeds respire just like any other living organism, requiring oxygen and producing carbon dioxide (CO2), so it is crucial to use a soil media that is sufficiently aerated so that the seeds do not “suffocate”.

89% of our growing experts recommend to directly sow watermelon seeds into the ground. What is direct sowing and why do I care about it?

Watermelon Growing Guide

(Stages 2-5: Growth)

Once seed has germinated and radicale has emerged the second stage of the plant growing process begins, developing from radicale to cotyledon -the embryonic first leaves of the seed forming a young seedling.

During the third stage of plant development cotyledon develops to 3-4 true leaves, stem begins to grow, becoming a mature seedling.

In the fourth stage the mature seedling develops to a young plant, ready for transplanting.

The fifth stage of plant development the plant is fully mature bearing fruit and/or flower.

The following guidelines apply to all of the watermelon plants’ needs during stages 2-5 from radicale emergence to full maturity. During these stages sunlight becomes a more active participant in plant growth and development than in the germination phase.

Soil pH is an important factor during these stages as well. What is pH and why is it important?
