How many watermelons develop on the vine?
It really depends on how many flowers get pollinated. it is best to limit it to a melon per 2-3 feet of vine.
I have a 4 foot x 4 foot space for a garden and I would like to grow watermelon. How much scace is required? Or perhaps I should pick another plant to grow.
How much space you need will depend on the variety, but since space is a premium for you, you should consider growing them vertically. This article will explain more: https://www.gardeningknowhow.com/edible/vegetables/vgen/growing-a-vertical-vegetable-garden.htm
Lots and lots of plant greens but just three melons staying small with one puckering up on end, and loads of blooms.

Some people say you should turn the watermelon fruit over when it is growing. Is that true?
I have not heard this one before and would assume that it is simply a falsehood, as they do not require turning to grow. Here is an article that you may find helpful: https://www.gardeningknowhow.com/edible/fruits/watermelon/growing-watermelon.htm
Why do watermelons split open when almost ripe?
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:

Our watermelons are rotting on the end. What do I need to give them? We water them weekly. We live in central Louisiana.
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 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.
I have a backyard vegetable garden in the northern California area. This is my third year of gardening, and the last two years all of my vegetables have been great, except my watermelons. The watermelon plant grows big and the vines grow long but no actual watermelons are produced. Do you have any tips or advice? Should I be giving it plant food or something?
