Trumpet Plant Seeds: Guide to Storing, Sowing and Germination

Trumpet plants, also known as trumpet vines or Campsis radicans, are a popular choice for gardeners due to their striking flowers and easy care. Trumpet plant seeds are a great way to propagate new plants and expand your garden. In this guide, we will take you through the process of storing, sowing, and germinating trumpet plant seeds.

Storing Trumpet Plant Seeds

If you have harvested trumpet plant seeds from your garden or received them from a friend, it is important to store them correctly to ensure their viability. The best way to store trumpet plant seeds is in a cool, dry place like a refrigerator.

To store trumpet plant seeds, follow these steps:

1. Place the seeds in an airtight container like a plastic bag or glass jar.
2. Label the container with the date and any other relevant information such as the plant variety.
3. Store the container in the refrigerator away from any fruits or vegetables that emit ethylene gas, which can reduce seed viability.

Stored correctly, trumpet plant seeds can remain viable for up to two years.

Sowing Trumpet Plant Seeds

Once you are ready to sow your trumpet plant seeds, there are a few things to consider. Trumpet plants prefer full sun and well-draining soil. They also require plenty of space as they can grow up to 30 feet in height.

To sow trumpet plant seeds, follow these steps:

1. Choose a location that receives full sun and has well-draining soil.
2. If planting in pots, use a potting mix specifically designed for seed starting.
3. Sow the seeds about 1/4 inch deep in the soil and cover lightly with soil.
4. Water the soil lightly so it is moist but not waterlogged.
5. Keep the soil moist until the seeds germinate.

Trumpet plant seeds typically germinate within 10-14 days.

Germinating Trumpet Plant Seeds

Germinating trumpet plant seeds is a relatively easy process. Once the seeds have been sown, they require consistent moisture and warmth to sprout.

To germinate trumpet plant seeds, follow these steps:

1. Keep the soil consistently moist by watering lightly as needed.
2. Place the container in a warm location with a temperature between 70-85°F.
3. Once the seedlings have emerged, thin them out to leave only the strongest ones.
4. When the seedlings have grown large enough, transplant them into their permanent location.

Frequently Asked Questions

Q: How do I know when my trumpet plant seeds are ready to be harvested?

A: Trumpet plant seeds are ready to be harvested when the pods turn brown and dry. The pods will also begin to split open, revealing the seeds inside.

Q: Can I propagate trumpet plants from cuttings instead of seeds?

A: Yes, trumpet plants can be propagated through stem cuttings as well. Take a cutting from an established plant and place it in a rooting hormone. Once roots have formed, transplant the cutting into soil.

Q: Are trumpet plants invasive?

A: Yes, trumpet plants can be invasive if not properly maintained. They can spread rapidly and take over other plants in the garden. It is important to prune them regularly and prevent them from spreading to unwanted areas.

Q: Can trumpet plants grow in containers?

A: Yes, trumpet plants can grow in containers as long as they are given enough space and sunlight. Choose a large container with well-draining soil and provide support for the vines to climb.

In conclusion, storing, sowing, and germinating trumpet plant seeds is a simple process that can result in beautiful and hardy plants for your garden. With proper care and attention, your trumpet plants will thrive and make a stunning addition to your landscape.
