How to Grow Pawpaw From Seed

The pawpaw is a unique and delicious fruit tree native to North America, prized for its creamy, tropical-flavored fruit. Growing pawpaw from seed is a rewarding process that allows gardeners to cultivate their own trees and enjoy this rare treat at home. While it requires patience and specific care, the result is well worth the effort.

This guide on how to grow pawpaw from seed will walk you through the key steps to successfully grow a pawpaw tree from seed, ensuring healthy growth and eventual fruiting.

Understanding Pawpaw Seeds

Pawpaw seeds are large, oval-shaped, and encased in a hard, dark shell. They come from the fruit of the pawpaw tree and must be handled with care to ensure successful germination. One important aspect of these seeds is that they are highly perishable and must remain moist to stay viable. Fresh seeds are the best option for planting, as dried or old seeds often fail to sprout.

Additionally, pawpaw seeds have a natural dormancy period and require stratification, a cold treatment process, to break dormancy and encourage germination. Understanding these characteristics is crucial for anyone looking to grow pawpaw trees from seed successfully.

When to Plant Pawpaw Seeds?

The ideal time to plant pawpaw seeds is in the fall, shortly after they are harvested. Planting them at this time allows the seeds to undergo natural stratification over the winter months, which is necessary for breaking their dormancy. If fall planting is not possible, the seeds can be stored in moist conditions at a temperature of around 32–41°F (0–5°C) to simulate the cold period they require.

Once the stratification process is complete, typically by spring, the seeds can be sown either indoors or directly into the ground as soon as the soil has warmed and there is no risk of frost. Proper timing is key to ensuring successful germination and healthy seedling development.

8 Steps on How to Grow Pawpaw From Seed

Step 1: Choose High-Quality Seeds 

The first step in growing pawpaw from seed is selecting high-quality seeds. Look for fresh seeds sourced from mature and healthy pawpaw fruit. Fresh seeds are more likely to germinate successfully compared to older, dried-out seeds.

If sourcing seeds from a supplier, ensure they are reputable and specialize in pawpaw or native plant species. Avoid seeds that appear damaged, shriveled, or have visible signs of disease, as these are less likely to produce viable seedlings. Starting with the best possible seeds greatly increases your chances of cultivating strong and healthy pawpaw trees.

Step 2: Stratify the Seeds

Stratification is a crucial step in preparing pawpaw seeds for successful germination. This process involves simulating the natural winter conditions the seeds would experience before sprouting in the wild. To stratify pawpaw seeds, place them in a moist medium such as damp sand, sphagnum moss, or vermiculite.

The seeds should remain consistently moist but not waterlogged to prevent rotting. Store the medium containing the seeds in a plastic bag or container and refrigerate it at a temperature of approximately 32–41°F (0–5°C) for 70 to 100 days. Regularly check the seeds to ensure they are moist and free of mold. Proper stratification breaks seed dormancy and prepares them for germination when conditions become favorable.

Step 3: Prepare Containers or Garden Bed 

Once the stratification period is complete, it’s time to prepare the planting area. Choose either containers with good drainage holes or a well-prepared garden bed in a location with adequate sunlight. Fill the containers with a high-quality seed-starting mix, or amend garden soil with compost to ensure it is rich and loose.

The soil should be well-draining to prevent waterlogging while retaining enough moisture for germination. Level the soil surface to create an even planting area, and lightly moisten it before sowing the seeds. Proper preparation of the planting medium ensures the seeds have the optimal conditions for sprouting and healthy growth.

Step 4: Planting the Seeds

If you’re using the fridge method, simply take out the seeds from the ziplock bag and plant them in your preferred container or garden bed.

If you’re using moist soil for stratification, make sure to dig a small hole (around 1-2 inches deep) and place the seed in it with the pointed end facing downwards. Lightly cover it with soil and water gently.

Step 5: Provide Proper Care

Pawpaw seeds require consistent moisture to germinate, so make sure to keep the soil moist but not waterlogged. You can also cover the container with plastic wrap to create a greenhouse effect and maintain moisture levels. Place the container in a warm spot, ideally between 75-80 degrees Fahrenheit.

Once the seedlings emerge, make sure to provide them with plenty of sunlight or artificial light for at least 6 hours a day. Continue watering consistently until they reach around 2 inches in height. Then, you can transplant them into larger containers or directly into your garden bed if you live in a suitable climate.

Step 6: Patience is Key

Growing pawpaws from seeds may take some time, as it can take up to 5 years for them to mature and produce fruit. But don’t get discouraged, as the wait will be worth it once you taste the delicious and unique flavor of fresh pawpaw fruit.

While waiting for your pawpaws to grow, make sure to continue providing them with adequate water, sunlight, and nutrients to ensure their healthy growth.

Step 7: Harvesting Pawpaws

Once your pawpaw trees are fully mature and producing fruit, it’s time to harvest! The ideal time to harvest pawpaws is when they start to fall from the tree on their own or easily detach from the branch with a gentle tug. If you have multiple trees, make sure to check each one individually as they may ripen at different times.

It’s important to handle pawpaws with care during harvesting as they can bruise easily. Gently twist the fruit off the tree and place it in a basket or bucket. Avoid stacking them on top of each other to prevent any damage.

Step 8: Storing Pawpaws

Pawpaws can be stored at room temperature for up to a week, but for longer storage, they should be kept in the refrigerator. Wrap them in paper towels and store them in a plastic bag to extend their shelf life. Pawpaws can also be frozen for later use by pureeing them and storing them in an airtight container.

When ready to use, thaw the frozen pawpaw in the refrigerator or at room temperature. Pawpaws can also be dehydrated by slicing them into thin pieces and placing them in a food dehydrator until they are completely dry. Store the dried pawpaw slices in an airtight container for up to six months.

Following these steps on how to grow pawpaw from seed and how to properly harvest and store the fruit will ensure a bountiful and delicious pawpaw crop.

Additional Tips for Growing and Harvesting Pawpaws

In addition to the steps mentioned above, here are some additional tips for successfully growing and harvesting pawpaws:

Consider Planting Multiple Trees

Pawpaws need cross-pollination from another tree to produce fruit, so it’s beneficial to plant more than one tree if possible. This will also increase the chances of having a successful harvest.

Choose a Suitable Location

Pawpaws prefer well-drained, slightly acidic soil and partial shade. It’s important to choose a location with enough space for the tree to grow (they can reach up to 20 feet) and where they won’t be in direct competition with other trees or plants for nutrients.

Prune Regularly

Pruning is important for maintaining the shape and health of your pawpaw tree. It should be done in late winter or early spring before new growth appears.

Protect from Pests

Pawpaws are susceptible to pests such as mites and borers. Keep an eye out for any signs of infestation and take necessary measures to protect your tree.

Harvesting

Pawpaws are ready to be harvested when they start to soften and turn light green or yellow. They do not ripen further once picked, so it’s important to pick them at the right time.
