crimson sweet watermelon seeds for growing an outdoor garden in summer

Grow Crimson Sweet Watermelon from fresh Citrullus lanatus melon seeds. Crimson Sweet will produce deliciously sweet fruits that weigh anywhere from 20 to 25 pounds. The hard outer skin is striped with green on green and the flesh is deep red. Each round fruit measures roughly 13 to 14 inches in diameter. The seeds are fairly small so it isn't a problem to pick them out before enjoying on a hot summer day.

The plants themselves will grow to a mature height of roughly 8 to 10 inches tall and will grow outwards taking up about 8 to 10 feet or so. Each vine will produce somewhere between 2 to 4 melons, depending on growing conditions. These juicy snacks will be ready for harvesting in about 90 days after first sprouts appear.

It's no shocker that the Watermelon is consisted of roughly 95 to 96 percent water, the other 5 to 6 percent is mainly sugar. There are a few health benefits when eating Watermelons, some of which you might not even know of.

sowing the seed

Sowing The Seed

You should know that Watermelons require plenty of space to grow, however this variety is great if you have little space to work with. In warmer climates, start indoors 6 to 8 weeks prior to the last frost. Sow in peat pots, at a depth of 1/2" to 1" under topsoil. Transplant entire pots when the weather is warm and all danger of frost has passed. You can direct sow outdoors in cooler climates. (Check "Germination & Growth" for spacing and plant information.)

growing conditions

Growing Conditions

Because Watermelons thrive in warmer climates, it is recommended to place the plants in an area that receives full sunlight for the majority of the day. For optimal germination and growth, temperatures should be kept between 72F and 80F. The soil should be rich, but also well drained, with a pH level between 6 and 6.8. Add a light compost to hard compacted soil to increase drainage. Water daily until germination has occurred.

germination and growth

Germination & Growth

Your Watermelon seeds will begin to sprout within as little as 7 to 14 days after sowing, vining outwards to take up an area of 8 to 10 feet. Plants should be spaced 3 to 5 feet apart, while rows should be spaced 5 to 8 feet apart. Harvest these delicious fruits roughly 90 days after the first sprouts appear, or when the bottom spot turns from white to yellow.

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 SeedsThe 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 5/1Adding 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 MoundsWatermelons 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 WatermelonsThe 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 DeeplyWeed 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 ripeWe 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.

For disclosure purposes, this is the first time I bought from this company and have never attempted to grow watermelons before. We purchased the seeds and they arrived with in a few days. While our garden is rather small, I took and germinated about 15 seeds in Soil3 mixture (From Supersod) in Styrofoam cups, with the expectation that less than half would ever germinate. After about 7-10 days, to our surprise 14 sprouted. After about 2 weeks when they were fairly stable and growing their 3rd set of leaves I planted them in our garden. Of the 14 about 10 seem very healthy and have started to flower. Overall I'm very happy with the seeds and look forward to delicious watermelons. Will provide an update later in the summer with photosUpdate: Its July 25th, the plants themselves have been growing and I have flowers, but still no watermelons, I water them on a regular basis and fertilize. I would have thought by now I'd have watermelons growing.

Planted every seed, sadly a bit late, but harvested 10+ good size tasty watermelons, 10+ stunted but still good ones, and several too tiny not fully ripened ones before winter came. Moved from that house and the new owners said they're still getting watermelons sprouting almost 2 years later after tilling the patch and putting a shed over top the area, they are resilient!

I counted the seeds and there were only about 97 and a few were broken seeds. Not a major issue but usually other seed companies include 5 or 10 more seeds because not all seeds are perfect. I picked out 12 of the best seeds and planted them. 11 out of the 12 seeds sprouted. Not bad, but these were 12 of the best looking seeds. We will see how the others do. Overall they sprouted and we will see in the summer the quality of melon they produce but just wish all the seeds were good or at least if they included a few extra to take into consideration some bad ones. I probably would still buy these seeds in the future and might update the review once they grow and ripen.

I started these a little late, but so far everything has germinated. Just hope I can get blooms and ripe fruit before the end of summer.

I gave it one star because the melons produced bear no resemblance to the melons described. I don't understand how people can sell products that are not what they promoted. Do they figure what the heck by the time they discover they got the wrong seeds, we'll have their money and it will be too late for them to do get a refund? The melons produced were edible and fairly good but that does not ameliorate the fact that the seeds did not produce the variety of melon we preferred. We expended a lot of time, energy and resources only to be disappointed by the results. I'll never buy any seeds from them in the future. In reading the other posted reviews, only one comments on the actual melons produced, the rest comment on the seedlings or size of the vines.
