Review: ~ RED SWEET WATERMELONS ~ - I ordered the Seeds for my Sister, she has a Farm and likes to grow all kinds of Fruits and Vegetables. The Seeds were Planted indoors in Planting Trays with good quality Soil. If you live in a Cold area the Seeds can be Planted indoors or Greenhouse 6 to 8 weeks before Planting outdoors, Plant with the point of the Seed pointing up, that is how my sister does it. You should water the Seeds well but not too wet, spraying with warm water is the best. Place the trays or pots in a warm area 80 degrees during the day, a Greenhouse is ideal but a Sunny countertop will work as well. We cover the containers with plastic wrap to create a Greenhouse like environment for the Seeds The Seeds Germinated Beautifully after 7 to 10 days and they should be transplanted outdoors in an area of the Garden with plenty of Sunshine. Aerate the soil with a Rake, removing all debris, the ground should free of stones, breaking up large clumps of packed earth and remove any vegetative matter or deeply incorporate it into the soil. The Seedlings are ready to be transplanted when they have reached a Height of 4 to 6 inches and have several leaves on them and after the Last Frost Date in your Area, average Planting Dates: 3/1 5/1 Adding equal parts of Loam and Sand to the soil is beneficial since Watermelons enjoy Rich Loamy Soil. Space the Seedlings after thinning, keep the strong Plants. Using a Hoe, form Mounds of earth, Small Hills, space these 5 to 7 feet apart depends on the amount of space you have at your place. Building the Soil Up as you making the Mounds helps assure that the Soil is loose enough for the Roots of the Plants to grow, allows oxigen to them and lets excess moisture drain away from direct contact with the Roots of your Plants. You should Plant the Seedlings 3 to 4 feet apart on top of the Mounds Watermelons are sensitive to Fertilizer Burn, mix Commercial ones well before applying and be Sparing, we like to use Natural Fertilizers without Chemicals, after all we like to eat the Watermelons free of any foreign substances. Watch out for the Cucumber Beetle, this Pest loves Watermelons. Other Pests include Aphids and Mites. If you have Wild Rabbits at your Place, Beware! They will Devour your Sweet Delicious Watermelons The Watermelons will form vines spreading up to 10 feet long and they will need plenty of room to grow. Adding Mulch around the Plants will help retain moisture and heat close to the Roots of the Plants thus helping them to thrive and Produce Healthy Fruit. After the Flowers Bloom water approximately every 3 days if dry, however, don't over-water, as Watermelons have a low water requirement. keep the Foilage and Fruit Dry, you can place Fruit onto a clean piece of wood or Garden Tiles, that is what we use to keep the Melons away fron the Soil and Clean. On very Hot days the leaves will probably Wilt even in moist soil, if this Limpness can still be seen in the evening after a Hot day, Water Deeply Weed regularly, be sure to weed around the base of the Plants along and ahead of the vines, you can apply a Commercial Black Fabric to the ground, they serve as durable weed barriers and the Watermelon vines and Fruit can grow on top away from the Soil and Bugs. The Watermelons begin to mature in 90 to 100 days after Planting the seeds. Melons are ready to Harvest when they are Heavy and Rich in Color, they weigh 25 pounds and up. Their Rinds are light Green in Color with Dark Green Stripes. Sweetness in Watermelons can be increased by holding off watering for a week or two prior to Harvest, however, don't do this if it causes the vines to Wilt. Once the Crop is Harvested, restore the usual watering to enable the second Crop to come through well, in perfect conditions Watermelons will mature to full sweetness in about 3 to 4 months of Warm Weather. To Harvest cut the Watermelons cleanly from the vine with a knife or Garden Shears. To test the ripeness of the Melons, Thump it, with your hand, if a dull noise sounding back means that it has ripened, also check the underside, it is ready when it has turned from White to Pale Yellow. Watermelons don't get sweeter after cutting them from the vine, so make sure they are ripe We like Planting Watermelons, it's a lot of fun and we Plant different varieties and love eating them. "Crimson Sweet Watermelon" is Delicious with Red Flesh Color bursting in Juice and very Sweet and luscious. The whole Watermelon keeps well in the Refrigerator for several weeks and about 4 days after you cut it in half. The 40 Seeds arrived from the Seller very Fast and without any problems, the Packet with the seeds included Information on how to grow your own "Crimson Sweet Watermelons" Good Luck, and wish you grow many of them! ...Thank You D.D.
Review: Good seeds - UPDATE: Planted on March 3, the first set of pictures was posted March 26 after a few true leaves sprouted. The first flowers arrived in late May. It's now early June, and the female flowers have arrived :). Of the 14 sprouted seeds, all the plants are alive, healthy, and doing well (some are flourishing more than others because of limited light in my garden, but that's on me). I'll update when the fruit is ready...if I remember to. The seeds were listed at 100 seeds, and I received 102. All were healthy-looking and appeared viable. I planted 18 seeds, and 14 germinated. I usually place them in a wet paper towel to start them, but this time I planted them directly in a seed tray (I probably won't do that again). I had the tray outside in the southern sun, and they germinated at different intervals, but the first took 5 days, and the rest took between 6-11 days to germinate. The plants look healthy, and I have no complaints. I would buy these again.

## Features

- Harvest - Crimson Sweet Watermelons will be ready to harvest 90 days after first sprouts appear. When ready, cut the fruits from the vine, leaving about 2 inches of stem to prevent rotting. Store for a week at room temperature, or 2 in the fridge.
