Watermelon Guava Physical Features:

Physical characteristics and cultivation

The common watermelon Guava has quadrangular branchlets, oval to oblong leaves that measure 7.6 cm (3 inches), and four-petaled white blossoms that measure 2.5 cm (1 inch) wide. The fruits are round to pear-shaped, with a diameter of up to 7.6 cm; the pulp includes numerous little hard seeds (which are more abundant in wild forms than in cultivated kinds). The fruit’s skin is yellow, while the flesh is white, yellow, or pink. The musky, at times unpleasant, scent of the beautiful pulp is only sometimes recognized.

Seeds are often used for propagation, although better varieties must be maintained through plant components. The plant’s stiff, dry wood and thin bark preclude cutting and traditional grafting procedures. However, veneer grafting produces good results when young plants in robust development are used as rootstocks. While the plant thrives in tropical regions and is commonly found growing in semi-wild form, it cannot withstand frost and is not frost-resistant. Although it can be efficiently cultivated in the southern part of Florida, in some areas, it has become bothersome due to its abundance.

Watermelon Guava Plantation

South Africa was the first to discover watermelon guava. It is a common cucurbitaceous vegetable in India. It is an excellent dessert fruit since its juice contains 92% water, proteins, minerals, and carbohydrates. Cubic watermelons are popular in Japan; they are grown in glass boxes and have a cubic shape. Watermelon grows best on soil that is deep, rich, and well-drained. When planted in sandy or sandy loam soil, it thrives. Watermelon cultivation is only appropriate for soils with good drainage. Crop rotation is essential because farming the same crop on the same land for an extended length of time results in nutrient loss, low yield, and increased disease assault. The soil’s pH should be between 6-7.

Popular Varieties Based on Yield

Shipper Enhancement: PAU in Ludhiana created it. Fruits are enormous, with dark green skin. These are pretty sweet, with TSS ranging from 8 to 9%. The average yield per acre is 70-80 ft. PAU, Ludhiana, developed Special No.1. Fruits are spherical and modest in size, with crimson flesh. These are types that mature early. TSS is less than that of Improved Shipper.

Land Preparation

Plow the earth to a lovely tilt. Sowing occurs in North India during February and March. From November through January, sowing occurs in North East and West India. Watermelons can be sown directly or transplanted in a nursery before planting.

Watermelon guava planting and propagation methods:

Watermelon Guava seedlings germinate in around three weeks. For this reason, freshly extracted seeds from completely grown fruits should be utilized. Plants can be grown in a nursery or in plastic bags. After being extracted from fruits, seed viability rapidly diminishes.

Because of the hard coat of the seeds, it is required to pour boiling water on them and soak them in water for two weeks before sowing or to treat them with sulfuric solid acid for five minutes to encourage germination. However, growing watermelon guava plants from seed is not recommended since seedling trees differ substantially from mother plants. Watermelon Guava thrives in hot and humid climates, typically from April to June.

During this period, relative humidity typically ranges between 69.0 and 80.0 percent, making it the ideal time for cultivation. A sprout from the previous year’s 1 cm diameter growth is used for air layering. The area is covered with wet sphagnum moss and fastened with polyethylene film. After 30–40 days, the roots appear. Air layering is a technique for reproducing new trees and shrubs while preserving the original plant. The stem is coated with moist moss to promote root formation.

Watermelon guavas are round to pear-shaped fruits that measure 5 to 7 cm in diameter.

Ethnic/Cultural Information

Guava jelly manufacturing in Florida was formerly renowned as one of the state’s thriving industries and a staple item in family kitchens.

Kidney Disorders May Be Relieved

Like many fruits and vegetables, watermelons contain a lot of potassium, which is known to help flush away harmful depositions in the kidney. Furthermore, they have been shown to lower the concentration of uric acid in the blood, which may lessen the risk of kidney injury and the formation of renal calculi.

Watermelon guava can also cause urine, which is beneficial for clearing the kidneys due to its high water content. Furthermore, the antioxidants in watermelon may help maintain kidney function for a long time while reducing indicators of premature aging, such as wrinkles and age spots on the skin. However, if you already have a renal illness, avoid eating watermelon since the high water and potassium levels may cause more harm than benefit.

Blood Pressure Control

According to research published in the American Journal of Hypertension [6], watermelon guava extract can significantly decrease blood pressure in obese patients with hypertension. Furthermore, the potassium and magnesium levels in watermelons may be beneficial in terms of blood pressure reduction. Potassium is a vasodilator, which may relax blood vessels and arteries, improving blood flow and reducing stress on the cardiovascular system.

Carotenoids contained in these fruits and others high in carotenoid content, such as watermelon Guava, may also aid in preventing arterial wall and vein hardening, lower blood pressure, and minimizing the risk of blood clots, strokes, heart attacks, and atherosclerosis.

Watermelon Guava Tree Care Tips for Guava Tree Growth

Guava trees, whether produced from seed or cuttings, can be planted outdoors (if your climate permits) or moved into large pots to be cultivated in greenhouses or conservatories.

Growing Situations

Guava trees thrive in locations with whole light and sandy, acidic soil most of the day. This soil will aid in removing excess water, preventing root rot, and helping your guava tree to thrive.


Because guava trees are tropical plants, they do not tolerate cold temperatures. Suppose you plant in a more temperate climate. In that case, your tree will benefit from extra insulation during the cooler months. Wrap horticultural fleece around your tree and pack straw inside for extra warmth. Guava trees planted in pots are easier to care for since they can be taken indoors when the season changes.

How to Make Delicious Guava Jam


Guava trees must be pruned since they may grow quite tall, making them unmanageable in all but the most extensive gardens. Tall branches can also impede sunlight from reaching the tree; restricting fruiting and pruning your plant once a year is a simple and easy technique to maintain it in good shape and maximize fruiting.
