Pawpaw Seeds – How To Grow Pawpaw From Seeds

Last updated on July 25, 2025

Growing papaya trees from seeds is an exciting and fulfilling gardening project, especially here in Nigeria. If you’ve ever wanted to enjoy the creamy, sweet fruit of the papaya tree (often called pawpaw locally) in your backyard, starting from seed is a rewarding path.

In this in-depth guide, we’ll cover everything from selecting Pawpaw seeds to nurturing your young seedlings through their crucial early stages. We’ll provide tips specifically tailored for our Nigerian climate, ensuring your success in starting these valuable plants.

TL;DR: Grow papaya from fresh, clean seeds in warm, moist conditions.

No cold stratification is needed. Plant in well-drained soil, ensure plenty of sunlight from day one, and water consistently. Seedlings are ready to transplant in 3-6 weeks, and fruits can appear in as little as 7-10 months from transplanting.

What is Papaya (Pawpaw) and Why Grow It in Nigeria?

Papaya (Carica papaya) is a fast-growing, tropical fruit tree that is widely cultivated across Nigeria. It’s renowned for its large, sweet, and nutritious fruit, which comes in various shapes and sizes, from the common yellow varieties to the popular red/orange types like ‘Solo’ or ‘Red Lady’.

Why Grow Papaya Trees in Nigeria?

• Nutritional Powerhouse: Papaya fruits are packed with vitamins A and C, crucial for good health, and are a good source of fiber.
• Fast Yield: Unlike many other fruit trees, papaya offers a relatively quick return, with fruits appearing within a year in ideal conditions.
• Economic Potential: Whether for home consumption or commercial sale, papaya is a staple in Nigerian markets and offers significant income opportunities for farmers.
• Adaptability: Papaya adapts well to various soil types across Nigeria, provided there’s good drainage.

By growing papaya from seed, you’re investing in fresh, healthy fruit and contributing to local food security.

Step 1: How to Source Quality Papaya Seeds

The journey to a healthy papaya plant begins with high-quality seeds. You can either harvest them from ripe fruits or purchase them from a reliable supplier.

Harvesting Seeds from Fresh Papaya Fruits

For the best germination potential, always use seeds from fully ripe, healthy papaya fruits.

1. Pick a ripe fruit: Choose a papaya that feels soft to the touch and gives off a distinct sweet aroma.
2. Extract the seeds: Cut the fruit open and scoop out the round, black seeds, which are covered in a gelatinous pulp.
3. Clean the seeds thoroughly: This is crucial. Gently rub and rinse the seeds under cool water in a sieve to remove all the pulp and gelatinous coating. Any remaining pulp can cause mold or inhibit germination.
4. Dry the seeds lightly: Lay the cleaned seeds on a paper towel or cloth for a day to air dry, preventing stickiness. Do not over-dry them under direct sun, as this can reduce viability.

Pro Tip: The Float Test

After soaking your seeds for 24 hours (as described in Step 2), you can perform a quick “float test.” Gently discard any seeds that are still floating on the surface. The heavier seeds that sink to the bottom typically have a higher viability and a better chance of germinating successfully.

Purchasing Seeds from a Supplier

If you don’t have access to fresh fruit, or if you want to grow specific high-yielding varieties, purchase seeds from reputable local agricultural suppliers or nurseries. Look for F1 hybrid papaya seeds (like ‘Red Royale F1 Dwarf Papaya’ or ‘Maradona F1’), as these often offer superior vigor, disease resistance, and earlier fruiting.

Step 2: Preparing Papaya Seeds for Germination

Unlike some temperate fruits, papaya seeds do not require cold stratification. They germinate best in warm, consistently moist conditions.

1. Soaking (Optional but Recommended): After cleaning and light drying, you can soak the seeds in lukewarm water for 24 hours. This helps soften the seed coat and can speed up germination. Discard any floating seeds, as they are usually not viable.
2. Choosing the Right Medium: Prepare a seed tray or small pots with a well-draining seed-starting mix. A good mix usually contains peat moss or coir, perlite, and some compost. It should hold moisture but not become soggy.
3. Moisture Control: The medium should be damp, not soaking wet. If you squeeze a handful, a few drops of water should trickle out, but it shouldn’t be dripping.

Step 3: Planting Papaya Seeds for Germination

With your seeds prepared, it’s time to plant them. Papaya seeds typically germinate within 2 to 4 weeks, though it can sometimes take a bit longer.

Best Time to Plant in Nigeria

The ideal time to plant papaya seeds in Nigeria is at the beginning of the rainy season (around March-April in the South, or May-June further North). This allows the seedlings to establish themselves with ample natural moisture before the dry season. You can also start seeds indoors earlier in nursery bags.

How to Plant the Seeds

1. Prepare your containers: Fill small nursery bags or seed trays with your well-draining seed-starting mix.
2. Plant the seeds: Plant 2-3 seeds per hole or bag, about 1-2 cm (half an inch) deep. This increases your chances of successful germination.
3. Cover lightly: Gently cover the seeds with a thin layer of soil and lightly press down.
4. Water consistently: After planting, water the soil lightly to help settle the seeds. Keep the soil consistently damp (but never waterlogged) until germination occurs. You can use a fine mist sprayer.
5. Provide warmth: Place the trays or bags in a warm location, ideally between 24-30°C (75-86°F). A shaded spot in the nursery or a warm windowsill indoors is usually sufficient.

Step 4: Caring for Papaya Seedlings

Once your seeds germinate and the tender seedlings emerge, they need consistent care to grow strong enough for transplanting.

Watering Papaya Seedlings

Papaya seedlings need regular, consistent watering to keep the soil evenly moist. However, avoid overwatering at all costs, as young seedlings are highly susceptible to “damping-off” disease and root rot if the soil is soggy. Ensure proper drainage in your nursery bags.

Initial Fertilizing for Seedlings

Papaya seedlings benefit from a very light initial feed once they develop a few true leaves. You can apply a diluted liquid balanced fertilizer (e.g., NPK 10-10-10 or 20-20-20 at ¼ strength) every 1-2 weeks. Alternatively, a dilute compost tea can provide gentle nutrients. Avoid strong fertilizers, which can burn delicate roots.

Mulching (Lightly)

A very thin layer of fine organic material (like finely shredded leaves or rice husks) around the base of the seedlings can help retain moisture and suppress weeds in the nursery.

Step 5: Transplanting Papaya Seedlings

Your papaya seedlings will typically be ready for transplanting to their permanent outdoor location when they are 15-20 cm (6-8 inches) tall, usually around 3-6 weeks after germination.

When to Transplant

The best time to transplant is during the rainy season, when the soil is consistently moist and the weather is warm. Transplanting on a cloudy day or in the late afternoon can help reduce transplant shock. For more on timing, check out What is the Best Time to Plant Pawpaws?.

Selecting a Planting Location

Papaya trees need a location with full sun from day one for optimal growth and fruit production. Choose a spot that’s sheltered from strong winds, as their shallow root system and soft stems make them vulnerable. For detailed guidance on site selection, read Best Place to Plant a Pawpaw Tree.

How to Transplant Papaya Seedlings

1. Prepare the site: Dig a hole that’s twice the width of the seedling’s root ball and deep enough so the top of the root ball is level with the surrounding soil. If you have heavy clay or laterite soil, amend it generously with compost, well-rotted manure (like poultry manure), and sand to improve drainage. Consider planting on a raised bed if drainage is a major concern.
2. Handle with care: Gently remove the seedling from its nursery bag, being careful not to disturb the roots. Papaya roots are sensitive to disturbance.
3. Plant: Place the seedling in the center of the hole. Backfill with amended soil, gently firming around the base to remove air pockets.
4. Water thoroughly: Immediately after transplanting, water the seedling deeply to help settle the soil around the roots.

Ongoing Care & Beyond

Once your papaya seedlings are successfully transplanted and established, they will transition into the rapid growth phase towards fruiting. At this stage, consistent watering, regular fertilization, pest and disease management, and eventual harvesting become critical.

Identifying Plant Sex (For Non-Hybrid Seeds)

If you are growing from random market seeds (not F1 hybrids, which are often hermaphrodite), you will get a mix of male, female, and hermaphrodite plants. While you can’t be 100% certain until they flower, there are some early clues growers look for:

• Male Plants: Often appear more slender and can be the first to flower, producing long, dangling stalks with clusters of small flowers. These flowers often have pollen, but do not bear fruit themselves.
• Female Plants: Tend to be stockier. Their flowers will be larger and grow directly from the leaf axils on the main stem. These flowers, once pollinated, develop into fruit.
• Hermaphrodite Plants: Also stockier, these plants have flowers that contain both male and female parts, allowing for self-pollination. Their flowers also grow directly from the leaf axils.

For guaranteed fruit from a single plant, starting with a known hermaphrodite F1 hybrid seed is always the best strategy.

Troubleshooting: Common Reasons for Germination Failure

If your papaya seeds haven’t sprouted after 4-5 weeks, one of these issues is likely the cause:

• Seeds Weren’t Viable: Seeds from an unripe fruit or those that are old and poorly stored may not be viable. Always use fresh seeds from a healthy, ripe papaya.
• Pulp Remained on the Seed: The gelatinous sac around the seed contains natural germination inhibitors. If not cleaned off thoroughly, it can prevent sprouting.
• Soil Was Too Wet: This is a very common mistake. Overly wet or soggy soil leads to fungal growth (“damping-off”) and causes the seeds to rot before they can sprout. The soil should be damp, like a wrung-out sponge, not saturated.
• Soil Was Too Cold: Papaya seeds need warmth to germinate effectively. If planted during a cool spell or kept in a cold, shaded spot, they will remain dormant.
