My friend planted watermelons and we noticed today that on the bottom of the little unripe watermelons, it is rotten. There are several of them like this. What causes this?
This can happen if the ground stays continually wet with the melons on the ground. Many areas have been experiencing record rainfall, and if this applies to your area than this is the likely cause. Placing the growing watermelons on a bed of straw or something that raises them off the ground will help prevent this.
I live in the state of Florida. I am trying to grow watermelon in my backyard. I prepared my sandy soil by adding topsoil and raised row followed by black plastic (this is how some of the growers do it). I transplanted plants into holes and plants seemed to be doing well, but I noticed a couple of my fruits are split, and they don't seem to be growing. They have been about the size of softballs, maybe a little bigger for awhile now. I use a garden hose with sprayer attachment to water. One gardener told my husband that I am watering too much. Then I read your article and it says to water at least 2 times a day in temps over 80 degrees. What am I doing wrong? Please help.
Irregular watering can cause this as well as overwatering. Are these watermelons in the ground or in containers? We recommend watering twice a day for watermelons in containers, but for ones in the ground a few times a week is all that you would need. This article will help you:

I live just west of St. Louis, MO and just about everyone I know has problems growing watermelons. Our soil has quite a bit of clay, so I have mixed in sand and peat but the results are the same (i. e.the melons grow a little larger than grapefruit size then they turn black on the end and rot). Any ideas? Am I not watering enough? Not enough of a certain mineral? Please help.
This is blossom end rot and it is caused by a lack of calcium in the plant. But, it is normally not caused by a lack of calcium in the soil, but rather the inability of the plant to take up enough calcium from the soil to support the fruit.
This article is about squash and blossom end rot, but squash and melons grow very similarly, so this article will help you with your melon problem:

My watermelons are shriveled up on the end. They were growing great, then all at once they quit growing and shriveled up on one end. What is causing that?

Why would the end of my watermelons turn black? The bottom looks good and they're not sitting against anything. Help.
Like tomatoes, peppers, and squash, watermelons can also be affected by blossom end rot. This condition happens due to a calcium deficiency. Calcium helps a plant create a stable structure. If a plant gets too little calcium while the fruit is developing, the end result is what you're experiencing. There are a few things you can try for blossom end rot treatment.
Water evenly, not too much or too little. Add a low nitrogen fertilizer to the soil. he s for optimal calcium uptake. Add lime to balance the soil’s pH if it is too low, (should be between 6.0 and 6.5). Add some gypsum to the soil for additional calcium. In addition, remove affected fruit and use a calcium rich foliar spray on the plant.
My watermelon seemed to be growing well, until yesterday. I went out and it was split wide open. What caused this?
Irregular watering is the cause of watermelon splitting. Watering a few times a week is generally all that you would need. This article will help you: https://www.gardeningknowhow.com/edible/fruits/watermelon/watering-watermelon.htm
I planted my watermelons approx. 60 days ago and there are lots of buds, but I have no melons yet. Have I done something wrong? Lots of buds though.
Have you seen bees flying in or around your garden? Must have those "flying pollinators" around to have fruit. If you have had flowers for 2-4 weeks but no signs of melons forming, it may be that bees have not pollinated the female flowers. I have cantaloupes that I have to manually pollinate because there are no signs of bees where I live.
where r u? watermelons can take up to 120+days,need a very long growing season.if you have blooms you should get melons soon
