Hawthorn Plant Seeds:
Guide to Storing, Sowing and Germination

Hawthorn plants (Crataegus spp.) are known for their beautiful flowers, vibrant berries, and their ability to attract wildlife. If you are interested in growing your own hawthorn plants from seeds, it is important to know how to properly store, sow, and germinate them. In this guide, we will walk you through the step-by-step process of successfully growing hawthorn plants from seeds.

Storing Hawthorn Seeds

When collecting hawthorn seeds, it is essential to ensure they are fully ripened. Wait until the berries turn a bright red color and begin to soften before harvesting them. Once you have collected the berries, gently remove the seeds from the fruit pulp.

To store hawthorn seeds, make sure they are completely dry. Lay them out on a paper towel or newspaper in a well-ventilated area for a few days until they are fully dried. Avoid exposing the seeds to direct sunlight or excessive heat, as this can damage their viability.

Once the seeds are dry, place them in a paper envelope or a small breathable container such as a mesh bag or a paper bag. It is important to choose a storage container that allows air circulation to prevent moisture buildup, which can lead to mold or fungal growth. Store the seeds in a cool and dark location with a temperature between 32°F and 41°F (0°C and 5°C) until you are ready to sow them.

Sowing Hawthorn Seeds

Before sowing hawthorn seeds, it is recommended to stratify them. Stratification is the process of simulating winter conditions to break seed dormancy and improve germination rates. There are two common methods for stratifying hawthorn seeds: cold stratification and moist stratification.

Cold Stratification

To cold stratify hawthorn seeds, place them in a plastic bag with a moistened substrate such as peat moss, vermiculite, or sand. Make sure the substrate is damp but not soaking wet. Seal the bag and refrigerate it for about 90 to 120 days.

Check the moisture level periodically during the stratification period. If the substrate becomes dry, mist it lightly with water to maintain proper moisture levels. After the stratification period is over, you can remove the seeds from the refrigerator and proceed to germination.

Moist Stratification

Moist stratification involves imitating the natural conditions in which hawthorn seeds would be exposed to moist soil during winter. To moist stratify hawthorn seeds, fill a container with a mixture of equal parts moistened peat moss and sand.

Place the hawthorn seeds in the container and bury them in the mixture, making sure they are evenly spaced and covered. Place the container in a cool location with temperatures between 32°F and 41°F (0°C and 5°C). Keep the mixture consistently moist throughout the stratification period.

Germinating Hawthorn Seeds

After stratification, it’s time to germinate your hawthorn seeds. There are different methods you can use depending on your preference and available resources.

Direct Sowing

Direct sowing is a straightforward method where you sow the stratified seeds directly into the ground or a growing container. Choose an appropriate location with well-draining soil and plenty of sunlight for your hawthorn plants.

Prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller. Make small holes or furrows in the soil, about 1 inch deep. Place one or two hawthorn seeds in each hole and cover them lightly with soil. Water gently to ensure good seed-to-soil contact.

Seed Trays or Pots

If you prefer to start your hawthorn seeds indoors, you can use seed trays or pots. Fill the trays or pots with a well-draining seed-starting mix. Moisten the mix before sowing the seeds.

Sow one or two stratified hawthorn seeds per pot or cell, placing them just below the surface of the soil. Cover the seeds lightly with the seed-starting mix and mist with water to ensure moisture penetration.

Place the trays or pots in a warm location with temperatures between 68°F and 77°F (20°C and 25°C). Ensure they receive indirect sunlight or provide artificial light using grow lights. Keep the soil consistently moist but not waterlogged.

Conclusion

Growing hawthorn plants from seeds can be a rewarding experience. By properly storing, sowing, and germinating hawthorn seeds, you can enjoy the beauty and benefits of these plants in your own garden. Remember to follow the steps outlined in this guide and be patient, as hawthorn seeds can take several weeks to germinate. With proper care and attention, you will soon have healthy hawthorn seedlings ready for transplanting into your desired location. Happy gardening!
