Growing nasturtiums as a houseplant can be a rewarding and beautiful addition to your indoor garden. Here are some step-by-step instructions on how to successfully grow nasturtiums indoors:
1. Gather your supplies: You will need pots or containers, potting soil, nasturtium seeds, and a light source. If you don’t have access to natural sunlight, you can use grow lights instead.
2. Prepare the pots: Fill the pots with potting soil, leaving about an inch of space from the top. Nasturtiums like well-draining soil, so make sure the pots have drainage holes at the bottom.
3. Plant the seeds: Place two seeds in each pot, about 1 inch deep in the soil. This will increase the chances of successful germination.
4. Provide light: Nasturtiums need bright light to thrive. If you have a south-facing window, that would be an ideal location. Alternatively, you can use grow lights placed about 6-8 inches above the seedlings. Keep the lights on for about 12-16 hours per day.
5. Watering: Keep the soil consistently moist, but not waterlogged. Nasturtiums prefer slightly drier conditions compared to other houseplants. Water the plants when the top inch of soil feels dry to the touch. Avoid overwatering, as it can lead to root rot.
6. Germination: Nasturtium seeds typically take around 10 to 12 days to germinate. During this period, ensure the soil remains consistently moist. You can cover the pots with plastic wrap or a clear plastic dome to create a humid environment and promote germination.
7. Thinning out seedlings: Once the seedlings have a few sets of leaves, it’s important to thin them out. Pinch out the weaker seedling, leaving one healthy and vigorous seedling per pot. This will allow the remaining plant to have enough space and resources to grow.
8. Fertilizing: Nasturtiums are not heavy feeders, but you can provide them with a balanced liquid fertilizer once a month. Dilute the fertilizer according to the package instructions and apply it to the soil around the plant.
9. Pruning and maintenance: As your nasturtiums grow, you may need to provide support for the vines to climb. You can use trellises or stakes to guide the growth. Regularly pinch off any dead or yellowing leaves to encourage healthy growth.
10. Harvesting and enjoying: Nasturtiums produce vibrant flowers that are not only beautiful but also edible. Harvest the flowers and leaves to add a peppery flavor to salads, sandwiches, or as a garnish. Enjoy the colorful and flavorful addition to your indoor garden!
Remember, each plant is unique, and it may take some trial and error to find the perfect conditions for your nasturtiums. Pay attention to the plant’s needs and make adjustments as necessary. With proper care, you can enjoy the beauty and benefits of nasturtiums as a houseplant.
