I am going to build a large planting box to plant a few hill's of watermelons. About what size of box should i build? Thank you and have a Bless Day. Mickey Reeves
Watermelons take up quite a lot of space, depending upon the variety. Are they all going in the same box? This article should tell you everything you need to know about spacing watermelon plants:

I am growing a "black" variety of watermelon. The fruits are small and greenish-black, and the contact point is already dark yellow before the fruit is ripe. I can't use typical indicators for ripeness (darkening rind, white-to-yellow spot, etc). How do I tell when to pick them? The crop was badly damaged by a hail storm and is just now bouncing back, so counting days won't necessarily be accurate. Help!
This article should help with some techniques to determine ripeness.

My watermelons started out gorgeous and healthy. But now there is this sticky looking web substance and tiny blackish bugs on one side of the patch. Are these mites? What can I do to save the plant? Fruit grows but only to shrivel up and fall off or turn blackish- purple.can someone please help?
You have more than one issue here... First... Let's address the mites. These will destroy your crop... fast! Now from here it gets tricky. There is a product that has saved my you-know-what several times... It is called Foxfarm's Force of Nature miticide. It is all natural, and very concentrated. 1/4 oz. to a bottle of water, and spray it all over. soak it... Now You appear to have another issue... Purple usually indicates to me a phosphorus deficiency... This is going to sound crazy but take a half bottle of the small gatorade (your choice of flavor lol) and pour it in. go ahead, laugh it up. ;) Now, lastly, you should think about resolving a pH issue that might be causing your deficiency... I would fix that with a product called Dolomitic lime (I use Agri-pel, I Live in Tennessee and a 40 lb bad costs me about 5 dollars. I handful per gallon of soil, or if it is in ground... about 5 small handfuls should do it.
I saved seeds from Carolina Cross watermelon, so when it dries up it becomes very flat. What could be the cause of it? And how to do I prevent it?
This seed is immature. It would seem the fruit was picked to early. I would let the melons go a little longer before you harvest. They should be dark black in color. These white seeds will not germinate. I believe I have sent you the information on storing seeds, but now I will provide an article for knowing when to harvest watermelons: https://www.gardeningknowhow.com/edible/fruits/watermelon/pick-a-watermelon.htm
How long do I have to store watermelon seed after harvesting, before I can plant out?
As long as it's warm enough outside, you can plant the seeds as soon as they've dried fully, which usually takes about a week. See this article for more information:
