How to start from seeds
If you’re looking to start growing from seed, there are a few things you should know to increase your chances of success. Here are some steps to follow:
- Collect Seeds:
The first step is to collect the seeds from a mature Douglas Iris plant. The best time to collect them is in late summer or early fall when the seed heads are dry and brown. Use a pair of scissors or pruning shears to cut the seed heads from the plant. - Prepare Soil:
Choose a well-draining soil mix and fill a container with it. Make sure the container has drainage holes at the bottom. Water the soil so that it’s moist but not waterlogged. - Sow Seeds:
Sprinkle the seeds over the soil surface and press them lightly into the soil. Don’t bury them too deep. Cover the container with plastic wrap or a lid to create a humid environment. Place the container in a warm place with indirect sunlight. - Water Regularly:
Keep the soil moist but not waterlogged. Water the container whenever you notice the soil is dry. Use a spray bottle to mist the soil surface if necessary. - Monitor Growth:
After a few weeks, you should start to see tiny green sprouts emerging from the soil. Remove the plastic wrap or lid and continue to water regularly. When the seedlings are a few inches tall, you can transplant them into individual pots or directly into the ground. - Transplanting:
When the seedlings have grown to a size of about 2 to 3 inches, they are ready to be transplanted. Choose a location with well-draining soil and partial shade. Dig a hole that’s slightly larger than the seedling’s root ball and gently place the seedling in it. Cover the roots with soil and press down lightly. Water the plant thoroughly.
With these steps, you can start growing Douglas Iris from seed and enjoy their beautiful blooms in your garden. Remember to be patient, as it can take up to two years for the plant to mature and produce flowers.
