When should I start watermelon seeds indoors?
While it is simple to direct-sow watermelon seeds, you can also start watermelon seedlings indoors 4–6 weeks before the last frost date. Watermelon can be successfully started indoors and transplanted outdoors. Plant 4-6 watermelon seeds directly in the garden when soils are 65°F. Seeds should be planted 1-2 inches deep, in mounds 4 feet apart. Thin the mounds after emergence to two plants. Transplant watermelon 2 feet apart through black plastic for early maturity.The foundation for growing giant watermelons begins with the soil. These heavy-feeding plants require soil that is nutrient-rich, well-draining, and capable of supporting vigorous growth.Watermelon is usually planted in hills. Plant 4 or 5 seeds per hill at a depth of 1 inch. Later, remove all but 2 or 3 healthy, well-spaced plants per hill when seedlings have 1 or 2 true leaves. Watermelon hills should be spaced 2 to 3 feet apart in rows 6 to 8 feet apart.A balanced nutrient approach is critical to maintain watermelon plant growth and maximize flower production. Nitrogen is a key element in boosting leaf growth. It is important that nitrogen supply is not limiting prior to flowering, or plant vigor and marketable yield will be adversely affected.Most fields are picked twice during the season. On average, each watermelon plant produces two to three harvestable fruit.
Can you start watermelon seeds in winter?
While it’s generally considered a summer fruit, growers in Florida are lucky enough to be able to plant watermelon for harvest in the winter as well. In fact, Florida is the only state in the country that produces watermelon from December to April. Season of Planting In North Indian plains, watermelons are sown in February-March whereas in North eastern and western India best time of sowing is during November to January. In South and Central India, where winter is neither severe nor long, these are grown almost round the year.Watermelons (Citrullus lanatus) are a warm season crop that grows best at average air temperatures between 70 and 85 degrees F. The soil temperature at a 3-4 inch depth should be 60-65 degrees F before the crop is planted. Melon seeds do not germinate well in cold soils.
What fertilizer is good for watermelon seedlings?
YaraLiva® Calcium Nitrate is the top choice for fertilizing watermelon during Vegetative Growth, Flowering and Fruit Set. YaraLiva calcium nitrate supplies readily available nitrate-nitrogen for fast growth and high productivity. Once the plant begins flowering, however, switch to feeding the watermelon a phosphorus and potassium based fertilizer. Watermelons require ample potassium and phosphorus for optimal melon production.Fertilizer Needs at This Stage At flowering and fruiting, watermelons require: Potassium (K): for fruit size, sweetness, and firmness. Phosphorus (P): to support continuous flowering and strong fruit set. Calcium & Boron: to prevent fruit cracking and improve quality.To help watermelons during their early growth stages, apply a fertilizer that’s high in nitrogen. As the fruit develops, switch to one higher in phosphorus and potassium to get the best results. A balanced 10-10-10 fertilizer is effective during their vigorous growing stage.
