The Complete Guide to Growing Impatiens from Seed
Impatiens flowers are truly a beautiful addition to any garden, with their vibrant colors and low maintenance needs. Whether you have a shady spot or full sun, there is an impatiens variety that will thrive in your garden. The only downside to these stunning annuals is the cost – buying dozens of plants can quickly add up. So, why not start your impatiens from seed? Not only is it more affordable, but it’s also a rewarding process that allows you to witness the growth of these beautiful flowers from the very beginning.
Why Start from Seed?
Starting impatiens from seed is not only cost-effective but also gives you more control over the growing process. By starting indoors, you can ensure the seeds have the right conditions to germinate and grow into healthy plants. Plus, it’s a fun and rewarding way to grow a garden full of vibrant blooms.
Here are the steps we’ll cover in this guide:
- When to Sow
- Preparation
- Sowing Your Seeds
- Transplanting
- Harvesting Seeds
When to Sow
While you can direct sow impatiens seeds outdoors, starting them indoors will give you better results. You’ll have more control over the temperature and growing conditions, which can help with germination. Impatiens seeds need a soil temperature of around 75°F to germinate, so starting indoors is ideal, especially if you live in a colder climate.
To determine when to start your seeds, count back from the last predicted frost date in your area. Plan to sow the seeds indoors about 11 weeks before you intend to plant them outside. For example, if the last predicted frost in your area is at the end of April, you should start sowing in early February.
Preparation
Before sowing your impatiens seeds, you’ll need to gather your supplies and prepare the planting trays or containers. Using a plug system like the iHORT QPlug Propagation Kit can make the process easier and more efficient. Make sure your containers are clean, have drainage holes, and are filled with seed-starting medium.
Place your trays or containers on a heating mat to maintain the right temperature for germination. Additionally, provide at least 12 hours of bright, indirect light for the seedlings. Keep the soil moist but not waterlogged, as impatiens seeds are slow to germinate and may rot if overwatered.
Sowing Your Seeds
When it’s time to sow your impatiens seeds, handle them with care due to their tiny size. You can either sprinkle them on the surface of the soil or use a seed sower for more precision. Cover the seeds with a thin layer of soil and keep them moist until germination occurs. Once the seedlings have two true leaves, you can thin them to ensure proper spacing.
Transplanting
After the risk of frost has passed and the seedlings have grown larger, it’s time to transplant them into the garden or containers. Harden off the seedlings by gradually exposing them to outdoor conditions before planting them in their final location. Prepare the planting site by amending the soil with compost and gently transplant the seedlings, ensuring they are well-watered.
Harvesting Seeds
If you’re interested in harvesting and planting impatiens seeds, it can be a fun and rewarding process. Impatiens plants use “ballistic dispersal” to send their seeds far and wide, so catching the seeds before they burst can be tricky. Use a clear plastic bag to collect ripe pods and prevent the seeds from scattering. While not all harvested seeds may grow true to the parent plant, purchasing seeds from reputable retailers can ensure consistency in your garden.
