How to propagate seeds
Growing plants from seeds is a rewarding way to start from scratch and watch every stage of development. It's especially great for herbs, veggies, and flowering annuals, but many houseplants can be grown from seed, too.
How it works
Seeds are sown in a suitable growing medium like soil, seed-starting mix, or even damp paper towels.
Sow them at the right depth (check your seed type)
Warmth and moisture activate germination.
Once they sprout and develop their first leaves (not the plant’s true leaves), the seeds enter the seedling stage
Tips for success
Use fresh, high-quality seeds for better germination.
Start with a light, well-draining medium (like a seed-starting mix).
Keep the environment warm - around 68–75°F (20–24°C) is ideal for most seeds.
Cover the container to increase humidity, but allow for some airflow, or open it up occasionally to prevent stagnant air and mold.
Label your containers if you’re sowing multiple types!
Keep the surface of the medium evenly moist, but never soggy.
Frequently asked questions
What are the benefits of propagating plants from seeds?
Growing plants from seeds is a rewarding experience that allows you to observe every stage of development. It is particularly suitable for herbs, vegetables, flowering annuals, and many houseplants.
What is needed for a seed to germinate?
Seeds need to be sown in a suitable growing medium at the correct depth. Germination is activated by warmth and moisture. After sprouting, seeds enter the seedling stage once they develop their first leaves.
What is the ideal temperature for seed germination?
Most seeds germinate best in a warm environment, ideally between 68-75°F (20-24°C). This warmth is crucial for activating the germination process.
What type of growing medium should I use for seeds?
Start with a light, well-dräining medium like a seed-starting mix. Seeds can also be sown in regular soil or even damp paper towels.
How do I maintain humidity for seeds without causing mold?
Cover your container to increase humidity, but ensure some airflow or open it occasionally to prevent stagnant air and mold. Keep the surface of the medium evenly moist, but never soggy.
