Cucamelon Melothria scabra
ABOUT
Melothria scabra, commonly known as mouse melon or Mexican sour gherkin, is a distinctive vine with a sprawling habit and small leaves that resemble those of a watermelon, though they are significantly smaller in size. The plant produces delicate, tendril-like structures that allow it to clamber over and cling to other plants or structures for support. The foliage is typically bright green and can be quite dense, giving the vine a lush appearance. The most captivating feature of this plant is its fruit. The mouse melon bears miniature fruits that are visually similar to watermelons but are the size of small grapes. These fruits have a smooth, striped rind in patterns of deep green and lighter green. When cut open, the insides look much like a cucumber's interior, complete with a watery flesh and small, edible seeds. The skin of the fruit is thin and crisp. As the fruit matures, it takes on a more yellowish hue. The mouse melon's flowers are also an attractive aspect of the plant with their dainty yellow blossoms. Despite their size, these flowers are quite noticeable and add a delicate charm to the appearance of the vine. Overall, the mouse melon has a whimsical, almost fairy-like appearance with its tiny melon-like fruits dangling from a web of greenery.

WaterFor the Mouse Melon or Mexican Sour Gherkin, it's best to water deeply once a week, providing about 1 or 2 gallons per plant each time, depending on climate conditions. They need consistent moisture, especially during fruit setting and growth, but the soil should be allowed to dry out between waterings to prevent root rot. Overhead watering is discouraged as it can promote foliar diseases; instead, use drip irrigation or water at the base of the plant. During periods of extreme heat or drought, you may need to water more frequently.
LightMouse Melon prefers full sun conditions, with at least 6 to 8 hours of direct sunlight per day. It thrives in a south-facing spot that receives ample sunshine and is sheltered from strong winds. If you're growing indoors, placing it near a sunny window or under grow lights that mimic natural sunlight can ensure it receives enough light to produce its characteristic small fruits.
TemperatureMouse Melon plants fare best in temperatures ranging from 70°F to 85°F. They can tolerate a minimum temperature of around 50°F, but growth will be stunted below this threshold. The plant cannot withstand frost and should be protected or harvested if temperatures are expected to drop near or below freezing. Ideal growing conditions include warm days and cooler nights to optimize plant development and fruiting.
PruningPrune Mouse Melons to maintain airflow and manage the plant's size. Remove any dead or diseased growth as needed throughout the growing season. Pruning is also beneficial for shaping the plant if it's being trellised. The best time for major pruning is in early spring before new growth starts, but light pruning can be done at any time, especially to facilitate harvesting or to remove any growth that impedes sunlight exposure to the fruits.
CleaningNot needed
SoilThe best soil mix for the Mouse Melon (also known as Mexican Sour Gherkin) is a well-draining, fertile soil with a pH between 6.0 and 6.8. A mix incorporating equal parts of garden soil, compost, and perlite or sand would provide both the nutrients and the drainage that these plants need to thrive.
RepottingMouse Melons should be repotted every one to two years to replenish nutrients in the soil and accommodate growth. They are vigorous growers and may need larger containers over time to avoid becoming root-bound.
Humidity & MistingMouse Melons prefer moderate to high humidity levels, similar to their native tropical and subtropical environments. A humidity level of 50-70% is suitable for these plants.
Suitable locationsIndoor
Place in bright, indirect light, and keep soil moderately moist.
Outdoor

Life cycleMelothria scabra, commonly known as the Mexican Sour Gherkin or mouse melon, begins its life as a seed typically planted after the last frost date in warm soil. Upon germination, it establishes a root system and produces vine-like growth with small, delicate leaves. Through the vegetative stage, it develops tendrils that enable it to climb and sprawl, needing support for optimal growth. It then enters its flowering stage, showcasing small yellow flowers that are monoecious, meaning each plant has both male and female flowers that enable self-pollination. Following pollination, the plant sets tiny fruits that resemble miniature watermelons, growing to about the size of grapes, which mature to a cucumber-like taste with a sour tang. Eventually, as the season ends, or with the onset of frost, the annual plant completes its life cycle and dies, with seeds saved or dropped to the ground to potentially give life to new plants the following season.
PropogationPropogation time
Spring-summer
Propogation: The most popular method of propagating the Mexican Sour Gherkin, or Melothria scabra, is by seed. Typically, gardeners start by sowing seeds directly into the ground or into pots after the threat of frost has passed and the soil temperature has reached around 70°F (21°C). The seeds should be planted about 1/2 inch (1.27 centimeters) deep, and spaced approximately 6 to 12 inches (15 to 30 centimeters) apart to allow for proper vine growth and air circulation. They must be kept consistently moist until germination, which usually occurs within 7 to 14 days. Once the seedlings emerge and grow to a few inches tall, they can be thinned out to avoid overcrowding. It's important to provide a climbing support for the plants as they have a vining habit. With proper care, including ample sunlight, warmth, and regular watering, the Mexican Sour Gherkin will produce a bountiful harvest.
