Pepino Melon – A Delicious and Fragrant Perennial Plant

The Pepino melon, scientifically known as Solanum maritacum, is an evergreen shrub that produces juicy and aromatic fruits. Let’s explore some key features and requirements for growing this plant.

Fruit Description

The Pepino melon bears fruits that come in bright green or yellow-green colors, sometimes with red or purple variegations. When ripe, the flesh turns golden, and there is a small seed cavity.

Taste and Edibility

Pepino melon fruits are entirely edible and highly enjoyable. They offer a delightful sweetness and juiciness that are truly satisfying.

Ecological Requirements

To successfully cultivate Pepino melon, certain ecological conditions must be met. Let’s take a closer look at these requirements.

1. Soils:
The plant thrives in well-drained deep soils with an optimum pH level of 6.5-7.5. It cannot tolerate saline soils.

2. Altitude:
Pepino melon is a cool season crop that can withstand conditions in areas with an altitude ranging from 1500 to 3000 meters above sea level (ASL).

3. Temperature:
For optimal performance, the plant prefers a temperature range of 12°C-24°C. High temperatures can negatively affect fruit production.

4. Rainfall:
Regions with an annual rainfall between 800mm-1200mm provide the best conditions for Pepino melon cultivation.

Growing the Plant

Let’s explore the recommended practices for growing Pepino melon.

1. Propagation:
The plant can be propagated using either seeds or cuttings. However, cuttings are more commonly used and easily propagated.

2. Spacing:
When planting cuttings, maintain a spacing of 3 feet by 3 feet between plants.

3. Cuttings Preparation:
To enhance rooting uniformity and break dormancy, soak the cuttings in a solution of 20ml of OPTIMIZER per 1 liter of water overnight.

4. Plant Height:
A mature Pepino melon plant can reach a height of up to 1.5 meters.

Pest and Disease Control

Like any crop, Pepino melon is susceptible to pests and diseases. Let’s take a look at common pests and recommended treatments.


1. Cutworms:
These brown or grey chewing pests reside in the soil near the plant’s root zone, cutting down young and tender stems. To control them, drench the soil with either 20ml/20l of PENTAGON 50EC or 60ml/20l of PROFILE 440EC.

2. Leaf Miners:
The larvae of leaf miners create irregularly shaped white mines under the leaf surface, reducing the area available for photosynthesis. To combat leaf miners, spray 5ml/20l of ALONZE 50EC or 10ml/20l of ESCORT 19EC.

3. Spider Mites:
These pests feed by piercing and sucking plant sap, resulting in stippled, yellowish, and dried-up leaves. They also produce webs on the undersides of leaves. Spray affected plants with 5ml/20l of ALONZE 50EC or 10ml/20l of BAZOOKA 18EC.

4. Fruit Fly:
Fruit flies attack young fruits, disrupting cell development and causing deformities. Infested fruits often drop prematurely. Use 8ml/20l of LEXUS 247EC or 5g/20l of PRESENTO 200SP to control fruit flies.

5. Whiteflies:
These white-winged insects feed on plant sap, causing damage and reducing plant vigor. They also secrete honeydew, which leads to the growth of sooty molds. Spray affected plants with 10g/20l of TAURUS 500SP or 8ml/20l of LEXUS 247EC.

6. Aphids:
Aphids suck sap from leaves, causing curling and distortion. They also secrete honeydew, promoting the growth of sooty molds. Spray affected plants with 10ml/20l of KINGCODE ELITE 50EC, PENTAGON 50EC, or LEXUS 247EC.


1. Anthracnose:
This disease causes circular black or brown sunken lesions on fruits, leaves, and stems. Spray affected plants with 15g/20l of RANSOM 600WP, BRADLEY 500SC, or DOMAIN 250EC.

2. Bacterial Spots:
Bacterial spots lead to the development of small greasy, dark green marks with black centers under the leaves. Fruit lesions may also appear as dark brown bumps. Spray affected plants with 50g/20l of GREENCOP 500WP or COLONIZER 440WP.

3. Early Blight:
Early blight initially manifests as small brown spots with concentric rings on lower, older leaves. Spray affected plants with 15ml/20l of EXEMPO CURVE 250SC, RANSOM 600WP, or FORTRESS GOLD 720WP.

4. Late Blight:
Late blight causes large water-soaked dark brown lesions with greenish-gray margins on leaves. Severe infestation can lead to defoliation. Spray affected plants with 25g/20l of GEARLOCK TURBO 250WP, FORTRESS GOLD 750WP, or TOWER 720WP.

Nutrition and Nutrient Deficiency

To ensure optimal growth and production, Pepino melon plants require adequate nutrition. Here are some important considerations:

1. Basal Fertilizers:
Basal fertilizers are primarily absorbed by the plant through the roots. Common examples include DAP (used during planting), CAN (for top dressing), NPK, and UREA.

2. Foliar Fertilizers:
Foliar fertilizers are sprayed onto the plant’s foliage and absorbed through the leaves. They include:

  • OPTIMIZER (10ml/20l): A stress manager that boosts immunity, stimulates growth, and prevents flower abortion.
  • DIMIPHITE (10ml/20l): Promotes flowering, fruiting, and increases fruit sugar levels.
  • VITABOR GOLD (60ml/20l): Enhances overall fruit quality.
  • GOLDCHANCE RANGE (50g/20l): Supports crop growth at different stages, boosting production.

Nutrient Deficiencies

1. Nitrogen Deficiency:
Nitrogen-deficient plants exhibit reduced growth rate and yellowing of older leaves. Correct this deficiency by spraying 20ml/20l of LAVENDER or 50g/20l of GOLDCHANCE SUPER GROWTH.

2. Phosphorus Deficiency:
Phosphorus-deficient plants have stunted growth and purplish leaves. Spray affected plants with 50g/20l of GOLDCHANCE SUPER START, 40ml/20l of PLANT SOUL, or 20ml/20l of LAVENDER.

3. Potassium Deficiency:
Potassium-deficient plants display small, dull leaves that appear cupped. Spray affected plants with 50g/20l of GOLDCHANCE SUPER FLOWERS & FRUITS, 20ml/20l of DIMIPHITE, or 50ml/20l of GREENPHITE.

4. Boron Deficiency:
Boron-deficient plants develop chlorotic and necrotic leaves, and their growing points may die off. Fruit quality also deteriorates. Spray affected plants with 20ml/20l of VITABOR GOLD.

5. Calcium Deficiency:
Calcium-deficient plants experience stunted growth, shortened internodes, and downward cupping of leaves. Blossom end rot may also occur. Spray affected plants with 60ml/20l of FERRARI GOLD or drench with 100ml/20l of SILVEDO GOLD.

Mix basal fertilizers with 1kg of HUMIPOWER per 50kg of fertilizer to improve nutrient uptake, stimulate growth, and enhance soil structure.

Weed Control

Weeds can compete with Pepino melon plants for essential resources. Effective weed control is crucial for maximum yield. Consider the following:

  • Before planting, spray weeds with 200ml/20l of CLAMPDOWN 480SL to minimize weed development.
  • Mulching can also help suppress weed growth.

Maturity, Harvesting, and Post-Harvest Handling

To ensure optimum flavor and sugar content, pick Pepino melon fruits only when they are fully mature, which usually occurs within 30-80 days after pollination. Ripe fruits have a pale yellow-orange flesh color. Handle the fruits with care to prevent bruising. They can be stored at room temperature for 4-6 days or refrigerated for several weeks.

Health Benefits

In addition to its delightful taste, Pepino melon offers various health benefits:

  • Reduces stress risks
  • Lowers the risk of hypertension
  • Helps in preventing diabetes
  • Reduces blood cholesterol levels
  • Boosts stamina and energy levels
