Pawpaw is an exotic tropical fruit that you can easily grow in your backyard or balcony. But, do you know how to grow pawpaw from seed? If the answer is no, then here’s a detailed guide on growing pawpaw from seed.

Growing pawpaw from seed might be intimating at first, but with the right step-by-step procedure, it really isn’t so daunting. This guide covers every single thing you need to know about growing your own juicy pawpaws from home. After reading this article, you’ll know exactly what to do in order to establish a lush and healthy tree of mouthwatering pawpaws that will bear yearly harvests.

The Best Climate for Growing Pawpaw

Pawpaw trees grow best in warm temperate to subtropical climates with moderate humidity and rainfall. The tree prefers full sun to partial shade and well-draining soils. It is hardy in USDA zones 5-8, which means it can tolerate temperatures as low as -25°F, making it suitable for growing in many parts of the United States, Canada, and Australia. If you live outside of its natural range, pawpaw can be grown in a greenhouse or container garden.

How To Grow Pawpaw From Seed

Step 1 – Collect fresh pawpaw seeds from ripe fruit

Step 1 in growing pawpaw from seed is to collect fresh seeds from ripe fruit. Pawpaw fruit is usually ripe during the late summer or early fall, and the seeds are located inside the fleshy interior.

It is important to only collect seeds from fully ripe fruit, as unripe fruit may contain seeds that will not germinate. Handle the seeds gently, as they are delicate and can easily be damaged. Once collected, clean and prepare the seeds immediately for planting to maximize the chances of successful germination.

Step 2 – Clean the seeds by removing any flesh or debris

It is critical to clean pawpaw seeds before planting to get rid of any flesh or debris that may contain bacteria, fungus, or other pathogens that can impede seed germination.

To clean the seeds, rinse them under running water and use a soft brush to remove any remaining flesh or debris.

Make sure that the seeds are completely dry before planting; moisture can cause mold or rot on the seeds. Once they have been cleaned and dried, the seeds are ready for prepping and planting.

Step 3 – Soak the seeds in water for 24 hours to soften the seed coat.

After cleaning the pawpaw seeds, the next step is to soak them in water for 24 hours. This process, called imbibition, helps soften the seed coat and make it easier for water and oxygen to penetrate – essential components for germination.

In addition, soaking the seeds helps to remove any remaining debris or flesh that was missed during the cleaning process. It’s important to remember to change the water every 6-8 hours to keep it fresh throughout the soaking period. After 24 hours, drain the water from the seeds and they will be ready for their next step.

Step 4 – Scarify the seeds by lightly sanding the seed coat with fine sandpaper

Scarifying seeds is the next step after soaking them in water. This process involves abrading or scratching the seed coat in order to let in more oxygen and water.

Scarification can be done by lightly sanding the seed coat with fine sandpaper or by gently rubbing the seeds between two pieces of sandpaper. This helps to break down the hard seed coat, which can increase germination success. However, it is important not to scarify too much because this can damage the seeds and reduce their chances of germination.

Step 5 – Stratify the seeds by placing them in a plastic bag with moistened peat moss or sand and refrigerating for 60-90 days.

After scarifying the seeds, the next step is to stratify them. Stratification exposes the seeds to cold temperatures for a period of time; this helps to break dormancy and prepare the seeds for germination.

To stratify your seeds, place them in a plastic bag with moistened peat moss or sand and refrigerate them for 60-90 days.

Make sure that the peat moss or sand is kept evenly moist (not wet) and check on your seeds regularly to make sure they’re not molding or rotting. Once stratified, your seeds will then be ready for germination and growing.

Step 6 – Fill pots or trays with seed compost and sow the seeds on the surface.

Once the stratification period is complete, the seeds are ready to be sown. Fill pots or trays with seed compost and evenly spread the seeds on the surface.

Seed compost is a specific soil mix that is designed for fostering seed germination, as it has the right balance of nutrients, moisture, and air necessary to support healthy seed growth.

When sowing your seeds, make sure they are placed in a warm spot that gets plenty of light but not direct sunlight.

Step 7 – Cover the seeds with a thin layer of compost or vermiculite.

After sowing the seeds, cover them with a thin layer of compost or vermiculite. This helps to keep the seeds moist and also to protect them from drying out or being washed away by heavy watering. It also helps to keep the temperature and humidity stable, which is essential for germination.

Step 8 – Keep the soil moist and in a warm place, around 25-30°C.

When growing from seed, it’s important to keep the soil moist but not overly wet. Waterlogging can cause mold or rot, so ensure that the soil has adequate drainage.

It should also be kept relatively warm, at a temperature of around 25-30°C. To achieve this, place the pots or trays in a propagator or cover them with a plastic bag.

Step 9 – Germination should take place within 2-3 weeks.

Pawpaw seeds typically germinate within 2-3 weeks, but this can vary depending on temperature, moisture, and seed quality. To ensure the successful germination of pawpaw seeds, check them regularly for signs of mold or rot, and remove any that show these signs.

Proper conditions and care are key to ensuring successful germination, so make sure the environment is kept sufficiently moist and warm enough for the seeds to grow.

Step 10 – Once the seedlings are big enough to handle, transplant them into individual pots and grow them on in a greenhouse or cold frame before planting them out in their permanent position.

Once the seedlings are big enough to handle, they should be transplanted into individual pots and grown in a greenhouse or cold frame.

Growing them in a greenhouse or cold frame will protect them from frost and wind until they are large enough to be planted out permanently.

To ensure the transplanted seedlings acclimatize effectively, it is important to harden them off before planting by gradually exposing them to outdoor conditions.

Tips for Caring for Your Pawpaw Tree

Here are some tips for caring for your pawpaw tree:

1. Provide the tree with well-drained soil and full sun to partial shade.
2. Water the tree regularly, especially during dry periods.
3. Fertilize the tree with a balanced fertilizer in the spring, before the tree starts to leaf out.
4. Prune the tree regularly to remove any dead or diseased branches.
5. Protect the tree from frost, especially when young.
6. Keep an eye out for pests and diseases aphids, and fungal diseases like powdery mildew, and take appropriate action if necessary.
7. Keep the tree mulched to help retain moisture and suppress weeds.

8. Consider companion planting with other plants that can help deter pests and improve soil health.
9. Pawpaw trees are dioecious (having separate sexes), so make sure you plant at least one male and one female tree to ensure fruit production.
10. Be patient, as pawpaw trees can take several years to begin producing fruit.

It’s also important to note that pawpaw trees can be propagated by both seeds and grafting. Grafting is a process in which a shoot or scion is taken from a mature tree and joined to the rootstock of a young tree. This can help to speed up the fruiting process, but it can be difficult to find a healthy scion.

Harvesting & Storing Pawpaw Fruit

Pawpaw fruit are typically harvested in late summer or early fall, when they have reached peak ripeness. The skin should be a slightly yellow color, and the flesh should give slightly to pressure when ripe. Carefully twist the fruit off the tree to harvest it; taking care not to damage the delicate flesh.

It is best to use or store pawpaw fruit soon after harvesting as they have a short shelf life. They can be kept in the refrigerator for several days before spoiling. For longer-term storage, you can freeze them by cutting them in half, removing the seeds, and placing them in an airtight container or bag. This way, they will last for up to several months when frozen.
