A step by step guide to Persimmon seed germination

Persimmon growing conditions

Location – Persimmons grown in cooler areas must have the full sun with protection from cooling breezes. As an attractive ornamental the tree fits well in the landscape and it does not compete well with eucalyptus.

Soil – Persimmon fruits can withstand a wide range of conditions as long as the soil is not overly salty, but does best in deep, well-drained loam. A pH level of 6.5 to 7.5 is preferred. The Persimmon tree has a strong taproot which may mean digging a deeper hole than usual when planting.

Irrigation – These trees will withstand short periods of drought, but the fruit will be larger and of higher quality with regular watering. Extreme drought will cause the plant leaves and fruit to drop prematurely. Any fruit left on the Persimmon tree will probably sunburn.

Persimmon seed collection

Persimmon seeds germinate best when fresh, gather them in autumn after the fruit begins to soften. Take a seed from fully ripe persimmons with no bird pecks, rotten spots, or green skin. After cutting open the Persimmon fruit, take out a few seeds and soak them in warm water for a few days to loosen any sticky flesh. Rub the seeds lightly under running water to clean them. You can start the seeds immediately or store them in a cool, dry space until you are ready to use them.

Persimmon fruits are berries usually containing 5 to 8 seeds and they can be collected in early fall after the fruit begins to soften. For larger trees, fruits must be collected soon after they fall from the branches and before they are eaten by small animals. The persimmon fruit is edible. Persimmon seeds can be easily removed from fruit after they are cut open. Any remaining fruit flesh adhering to the seed could be rubbed off in running water. It can be more easily removed if the seeds are soaked in water several days. Then they can be stored dry for long periods in airtight containers in the refrigerator.

Starting Persimmons from seed or germination of Persimmon from seed

The cheapest method of growing persimmons is to gather seeds from wild trees and sprout them right where you want your persimmon to grow. First, gather whole persimmon fruits and then remove the seeds, but don’t let the seeds dry out.  Your seeds will want to stratify, so plant them in fall or winter, no more than an inch deep in the soil.  Persimmon seeds won’t germinate until late spring, so if you want to be able to keep track of them, you might try planting seeds in outdoor pots at this time of year. Then transplanting seeds into their final location as soon as they germinate and before they send down their long taproot.  If you select the pot method, plant your seeds in soil taken from the woods to promote germination.

Seed treatment for Persimmon germination

Persimmon seeds want a period of moist chilling to help them germinate. The chilling, or cold stratification, process mimics the natural procedure of overwintering the seeds outdoors. Wrap the seeds in moistened sphagnum moss or paper towel, then put them in a plastic bag or jar inside the refrigerator for 2 to 3 months. If the moss or paper towel dries out, spritz it with some water to keep the seeds moist.

Seed dormancy – Persimmon has physiological dormancy.

Seed germination conditions of Persimmon

Stratify seeds using moist chilling for 60 to 90 days to satisfy physiological dormancy. Following stratification, sow seeds in a nursery container to produce a seedling or sow them in a plastic container in the room to observe germination.

Persimmon seedlings form a long taproot early on, so they want to be grown in tall plastic containers that will allow the root to form without cramping it. Sow one Persimmon seed per pot in the sterile potting mixture, and make sure the pot has drainage holes at the base. Plant the Persimmon seeds at a depth of 2 inches, and then set the pots in a warm, bright location. If daytime temperatures stay below 70°F, try warming the pots with a propagation heating mat. Tiny persimmon seedlings should appear in 6 to 8 weeks. Persimmon fruit seeds have a relatively low germination rate of 25 to 35 percent, so start multiple seeds to increase the likelihood of success.

Persimmons propagation

Seedlings used for the propagation process can be grown from fresh seed that has been extracted during autumn from ripe fruit. To facilitate extraction the fruit could first be fermented in drums. The collected persimmon seed is washed and stored dry.

The persimmon seed is sometimes germinated in flat trays and when 15 to 20 cm high the seedlings are transplanted into the nursery rows during spring. Take care at this phase to prevent loss of roots through drying out. Seedlings are generally large enough for budding or grafting at the end of the first season’s growth.

Growing Persimmons from seed

To grow Persimmon from seed choose a fully ripe, unblemished persimmon. Remove the seeds and soak them in warm water for 3 days. Once the seeds have soaked, rinse them under running water to completely remove any flesh.

Once you have soaked and cleaned the seeds, they want a period of cold stratification. The stratification procedure mimics the overwintering they need to sprout. Wrap seeds in a moistened paper towel and place it in a glass jar. Store the jar in your refrigerator for 3 months, spritzing the paper towel when it begins to dry out. This cold-treatment is called stratification and breaks the seed’s dormancy, which can inhibit germination. Start it late in the fall or early in the winter, about 5 months before the last spring frost. Throughout the 3 months, periodically check the medium, and spray it with a water-filled bottle so it stays moist the entire time.

Put peat pellets in a tray or cake pan that’s filled with about 1 inch of water and allow the pellets to soak up the moisture and expand. Discard any leftover water, and press one persimmon seed in each pellet to a depth of 1 inch. Then, place the tray in a clear, plastic bag to create a humid environment. The seeds germinate in 2 to 3 weeks in dark or light conditions in a temperature range of 68 to 86°F.

Remove the plastic bag as soon as the persimmon seeds germinate. Put the tray with the peat pellets in a sunny, south-facing window so the seedlings can grow. The ideal temperature during this phase is 65 to 70°F during the day and 55 to 60°F at night. Periodically rotate the tray so the seedlings produce upright and don’t have to reach for the light. Alternatively, suspend two, 40-watt fluorescent lamps 6 inches above the seedlings and keep the lamps on for 16 hours a day. As the seedlings grow, move the lamps up so always remain at least 6 inches above the young plants.

Fill 4-inch pots up to one-third of the way with moist potting mix when the seedlings are about 3 inches tall. Put a peat pellet with a seedling in the center of each pot and continue filling the remaining two-thirds of the pot with a moist potting mix. Maintain the soil moist as the seedling grows.

Harden off the young persimmon plants over 2 weeks before transplanting them in the garden after the last spring frost. Place the pots in a sheltered area outside for 2 hours a day and gradually extend the duration that you leave them outside so they slowly acclimate to the outdoor environment.

After the cold stratification procedure is complete, plant one seed in a tall, plastic container with drainage holes. The container needs to be tall because persimmon trees develop their long taproot early. The seed should be planted 2 inches deep in sterile potting soil and placed in a bright location where the temperature is at least 70°F. Because persimmon seeds have a 25 to 35% germination rate, plant multiple seeds for the best chance of success. You should see persimmon seedlings in 6 to 8 weeks.

Keep persimmon seedlings in bright, indirect sunlight with evenly moist soil. Once all danger of frost has passed, move potted persimmons to a sheltered area outdoors. Harden them off over 2 weeks by gradually moving them to an area with stronger sunlight. Water weekly to keep the soil moist, but persimmons don’t like soggy conditions, and then let the top inch of soil dry out between watering.

Persimmon seedling care

Bright, indirect sunlight, and evenly moist soil provide the best conditions for seedlings. Also, keep them outdoors under sheltered conditions during the spring months before slowly exposing them to stronger sunlight over 1 to 2 weeks. Water the seedlings weekly, but allow the soil to dry out in the top inch between watering to keep the roots healthy.

Seed transplant of persimmon

Due to their long taproot, seedlings need to be planted out at the end of their first full growing season, preferably in autumn after the first rain. Choose a planting site with at least 20 square feet of space per persimmon tree to give enough room for their mature spread. Persimmon trees are tolerant of most soil types, but they do not do well in seaside areas with saline soil. Overall, they give very little care and no special fertilizer to bear a hefty crop of fruit. Though, persimmon trees can take three to five years to bear fruit, so they do require patience.

Stratify Persimmon seeds

Persimmon seeds have a thick, hard outer shell that prevents germination until the seeds detect ideal environmental conditions for plant growth. By stratifying the seed, you crack or wear down the seed coat, allowing for the faster germination process.

Refrigerator stratification
  • First, dampen a handful of sphagnum moss and bury the seeds in the center of the moss.
  • Put the moss and seeds inside a small plastic bag. Seal the bag to maintain the moisture in.
  • Store the bag of seeds in the vegetable drawer of your refrigerator for 2 months.
  • Remove the bag and check for the germination process. If the seeds have sprouted, plant them in the soil as soon as possible.
Winter weather stratification
  • Fill a seed-starting tray or small container with gritty sand.
  • Plant the persimmon seeds about 1/2 inch deep. If using a tray, plant 1 seed per cell. For other containers, space persimmon seeds several inches apart.
  • Dig a hole in the yard or garden large enough to accommodate the seed tray, as well as 2 inches of gravel.
  • Pour about 2 inches of gravel into the hole. In midwinter or late winter, when temperature ranges are still cold, set the container on top of the gravel layer. And pack soil around the container.
  • Then, cover the container with a layer of pine straw. Watering is unnecessary; winter precipitation provides enough moisture for stratification.
  • Uncover the container in 60 to 90 days, as spring arrives, to check for the germination process.

Questions about growing Persimmons.
Questions about growing Persimmons.
Do you need 2 persimmon trees to produce fruit?

Persimmon trees provide the home garden with vivid colors in the fall and tasty fruit in the winter season. Varieties of the American persimmon typically require two trees to produce. If you have space for one tree there are several alternatives you can consider.

How long does it take to grow a persimmon tree from seed?

Persimmon trees grown from seed can take 3 to 5 years to bear fruit.

Why persimmon leaves curling?

When persimmon trees are heavily infested with scales, leaf damage includes wilting and yellowing, which can affect in defoliation. Scale insects can cause the plant leaves to curl or develop blemishes. And scales feed on the plant juices, and soft scale species secrete honeydew. This can lead to sooty mold on plant leaves and twigs.

Why is persimmon tree dying?

While excess water can cause Persimmon trees to die, not enough water can also kill your tree. Persimmon trees are drought resistant, but a prolonged drought can cause the tree to die.

Why do persimmons turn black?

Persimmons will eventually get soft, but they will never ripen and develop good flavor. Don`t be concerned about the black spots on some persimmons. When the fruit is soft and ripe, this astringency disappears.

How much time takes for persimmon trees to bear fruit?

Oriental persimmons bloom after 5 years but do not bear fruit until after 7 years. Grafted trees bloom within two to three years. American persimmon could take several years to blossom and still not fruit for up to 10 years. Both American persimmons and Oriental persimmons have alternate year blooming and fruiting.
