How to Grow Impatiens from Seed

Choosing and Collecting Impatiens Seeds

Impatiens seeds

Impatiens are one of the most popular and colorful bedding plants grown in gardens worldwide. Known for their bright and showy blooms, they are easy to grow, making them an ideal choice for novice gardeners. Growing impatiens from seeds is an economic and rewarding way to get a lush and vibrant garden in no time. In this article, we will guide you on how to choose and collect impatiens seeds that will germinate readily and produce healthy plants.

Impatiens produce seed pods when their flowers fade. The seed pods are reddish-brown in color and look like small, elongated balloons. Impatiens seeds are tiny and dark brown or black in color. You can collect these seeds for planting in your garden the following year.

The ideal time to collect impatiens seeds is when the seed pods become ripe, and they start to split open. To check if the impatiens seed pod is ready for harvesting, gently squeeze it between your fingers. If the pod opens up with no resistance, then it’s time to collect the seeds. Ensure you collect the seeds before the pod splits open, and they scatter all over your garden.

To collect impatiens seeds, start by cutting off the seed pod from the plant using pruning shears or sharp scissors. Place the seed pods in a paper bag or paper envelope and label it with the plant’s name and the collection date. Store this in a cool, dry place, away from sunlight, and let it dry for two to three weeks. Once the pods are dry, gently open them, and remove the impatiens seeds.

It’s important to note that impatiens seeds do not remain viable for long periods. They lose their germination capacity rapidly, and you may not get good results if the seeds are old. For this reason, always collect fresh impatiens seeds every year. Additionally, ensure you only collect seeds from healthy plants that exhibit desirable traits such as abundant blooms, robust growth, and disease resistance.

If you don’t have plants in your garden but still want to grow impatiens from seeds, you can purchase seeds from a reputable seed supplier. There are several impatiens varieties available in the market, including single-flowered and double-flowered types, in different colors such as white, pink, red, and orange. When buying seeds, choose a variety that suits your growing conditions, such as sun exposure and soil type, to ensure success.

In conclusion, growing impatiens from seeds is a fun and easy way to add color to your garden. By choosing and collecting fresh impatiens seeds from healthy plants or reputable seed suppliers, you can be sure of getting healthy and vigorous plants that will bloom beautifully.

Preparing Soil and Containers for Seed Sowing

To grow impatiens from seed successfully, it is essential to prepare the soil and containers adequately. The right soil and proper containers ensure that the seeds have the necessary nutrients to germinate and grow into healthy plants. The following are tips on what you need to prepare the soil and containers for seed sowing.

Choosing the Right Soil for Impatiens Seeds

The right soil for impatiens seed growing is loose and well-draining. Impatiens are susceptible to root rot, so it is crucial to choose soil with good drainage. Loamy soil with plenty of organic matter is ideal, but sandy soil can work in a pinch if combined with compost. Avoid clay soils as they tend to hold onto water, which can suffocate the seed or promote fungus growth.

You can use store-bought potting soil or make one yourself. Homemade soil requires combining loam soil, perlite, and compost in equal parts. Loam soil is a sandy clay mixture that provides the seed with necessary nutrients. Perlite is an inorganic soil amendment that provides aeration and drainage for your soil. Compost is an excellent source of nutrients for seedlings and improves soil structure.

Preparing Containers for Impatiens Seed Sowing

The container you choose for impatiens seed germination has a significant effect on plant growth. There are different types of containers to choose from, including seed starting trays, peat pots, coir pots, and plastic pots. The container you choose should have proper drainage, be sterilized, and free from contaminants to prevent the growth of fungi and diseases that can kill your seedlings.

To sterilize the container, wash them with warm soapy water and rinse with water. Then, soak in a solution of one-part bleach to ten-parts water for 30 minutes, rinse, and allow to air dry.

Using seed starting trays makes it easier to transplant seedlings into larger pots when they outgrow the small seed tray. However, the soil in trays can dry out faster, so keep an eye on them and supply enough water. Peat pots are biodegradable and can be planted directly into the soil, but they often dry out quickly. Coir pots are made from coconut fibers, making them an eco-friendly option, but they tend to be expensive. Plastic pots are reusable, affordable, and provide the best moisture retention, but they don’t break down quickly.


By following these tips, you can prepare the soil and containers for impatiens seed growing, ensuring your plants have the best start possible. Remember, loose and well-draining soil is essential, and your pots require adequate drainage and sterilization. With the right soil and containers, your impatiens seeds will sprout and grow into healthy, beautiful plants.

Sowing Impatiens Seeds Indoors

Sowing Impatiens Seeds Indoors

Impatiens is a popular bedding plant that can add vibrant color to your garden or landscape. While it is possible to grow impatiens from seeds, it can be a little tricky and requires some patience. However, with the right techniques, you can successfully grow impatiens from seed and enjoy the blooms throughout the growing season. In this article, we will discuss how to sow impatiens seeds indoors and get them ready for the outdoor garden in spring.

Impatiens seeds are very small, so it is recommended that you start them indoors in seedling trays. You can purchase impatiens seeds from a garden center or online supplier. Look for seeds that are fresh, plump, and free from any mold or disease. It is best to sow seeds in sterile potting soil that has been moistened. The soil should be gently pressed down so that it is firm but not compact.

Here are the steps for sowing impatiens seeds indoor:

Step 1: Fill Seedling Trays with Potting Soil

Fill a seedling tray with potting soil, then water it so that it is moist, but not soaking wet. Press down gently on the soil to make it firm and level.

Step 2: Sowing Seeds

Sprinkle the impatiens seeds onto the top of the soil, making sure that there is space between each seed. Do not bury the seeds in the soil, just press them gently into the surface, so they are in good contact with the soil. Keep in mind that impatiens seeds are very tiny, so be careful not to use too many or drop them.

Step 3: Cover Trays with Plastic

After sowing the seeds, cover the trays with plastic wrap or a clear plastic lid. This will help to create a humid environment for the seeds to germinate. Put the tray in a warm, well-lit area, but not in direct sunlight. Impatiens seeds need some warmth to germinate, so keep the temperature between 70-75 degrees Fahrenheit. If the temperature is too low, the seeds may not germinate at all.

It’s essential to keep the soil moist, but not too wet. Check the trays daily and spray them with water as needed to keep the soil moist but not soaked. Too much water can cause the seeds to rot. Once the impatiens seeds germinate, remove the plastic from the trays and keep them in a well-lit area that gets some direct sunlight. At this stage, it is crucial to keep the soil moist and the young plants well-watered.

Remember, impatiens are sensitive to frost, so wait until the last frost date before transplanting them to the outdoor garden. To harden off the seedlings, gradually expose them to outdoor conditions. Bring them outside for a few hours a day and gradually increase the amount of time they spend outside over a week or two. This will allow the plants to get used to the outdoor environment and prevent shock.

Once the seedlings are hardened off, plant them in well-drained soil with compost or manure. Make sure the soil is fertile and free from any weeds. Space the young plants at least eight to ten inches apart. Water the plants regularly, especially during hot, dry spells. Once the impatiens settle into the garden, they should begin to bloom. Deadheading the plants will encourage more blooms and prolong the blooming season.

Overall, growing impatiens from seed is a rewarding experience that can be both fun and challenging. By following the above steps, you’ll be successful in producing healthy and vibrant impatiens plants, which are the pride of your garden. Happy gardening!

Transplanting Impatiens Seedlings Outdoors

Transplanting Impatiens Seedlings Outdoors

After a few weeks of growing indoors, impatiens seedlings will be ready for transplanting outdoors. It is essential to wait until the last winter frost has passed before transplanting them. If it is too cold, the seedlings will die.

Before transplanting impatiens seedlings, it is crucial to prepare the garden bed. Start by removing any weeds, rocks, or debris. Loosen the soil and mix in some compost or aged manure, which will provide the plants with essential nutrients and good drainage.

It is best to transplant impatiens seedlings on a cloudy or overcast day to reduce the shock of sun exposure. Choose a location that receives partial shade or dappled sunlight, as impatiens thrive in cool and damp conditions.

Using a trowel or garden spade, dig a hole deep enough to accommodate the root ball of the seedling. Gently remove the seedling from its starting container, being careful not to damage the delicate roots. Place the plant in the hole, and backfill with soil. Press down gently around the base of the plant to remove any air pockets and firm the soil.

Space the seedlings 8-12 inches apart, as impatiens will quickly fill in the gaps between plants. It is beneficial to mulch around the plants with bark chips or straw to help retain moisture and regulate the soil temperature.

After transplanting, water the plants well and monitor them closely over the next few days. Be sure to keep the soil moist, but not waterlogged, as impatiens are susceptible to root rot. If the weather is exceptionally dry, water the plants daily until they are well established.

Impatiens are low maintenance plants, but they do require some attention to thrive. Regularly deadhead spent flowers to promote new growth and prevent the plant from going to seed prematurely. Feed the plants every two weeks with a balanced fertilizer, following the manufacturer’s instructions.

With proper care, impatiens will reward gardeners with a beautiful display of colorful blooms throughout the growing season. Transplanting seedlings outdoors is an easy and rewarding process that will provide gardeners with an abundance of vibrant flowers all summer long.

Choosing the Right Soil

Choosing the Right Soil for Impatiens Seed

If you want your impatiens to grow and thrive, then you need to make sure they are planted in the right soil. Choose a lightweight, porous soil that will retain moisture. Avoid using soil that is heavy and compact, as this will not provide the drainage impatiens need to grow. If you have clay soil and want to plant impatiens, then you need to amend the soil first. Mix in some organic matter, such as compost, to make the soil more porous and give your impatiens a better chance of success.

Another important aspect of the soil is the pH level. Make sure to test the soil before planting your impatiens and make any necessary adjustments. Impatiens prefer a slightly acidic soil with a pH between 6.0-6.5. If the pH level in your soil is too low, then you can add lime to raise it. If the pH is too high, then you can add sulfur.

Finally, make sure the soil is free from weeds and other debris before planting your impatiens. Weeds can compete with your impatiens for nutrients and water, while debris can block air and light from getting to the seeds.
