This will help improve drainage and aeration in the soil, which are essential for healthy plant growth. Once the ground has been cleared, you must add organic matter to enrich the texture of the soil and promote growth. Nasturtiums prefer well-drained soils with a pH of 6.0-7.5. You can also add lime or sulfur to adjust the acidity level. Finally, add plenty of organic amendments before planting your Nasturtium seeds.

Growing Nasturtiums in pots
- Nasturtiums are the best addition to any garden because they add color and texture. They grow well in pots but do best if planted in full sun. Nasturtiums need deep pots because they grow very tall. A 6-inch pot will be fine for a small Nasturtium, but a 12-inch pot is better for larger plants. Avoid using shallow containers because the roots won’t have enough soil to grow deep, and the plants will be more susceptible to root rot.
- Nasturtium plants grow best in containers at least 12 inches in diameter and six inches deep. Choose potting soil high in organic matter and containing adequate water, phosphate, and nitrogen. Sow the seeds directly into the container soil and water them regularly. Nasturtiums will reach maturity in about 60 to 70 days.

Nasturtium can be grown from seed, but they do best if grown in a trellis. Trellises will help the Nasturtium to grow tall and produce bigger flowers.
Why are my Nasturtiums so leggy?
You can grow Nasturtiums from seed, and they will reward you with large, vibrant blooms in early summer. However, if your Nasturtiums are leggy, there may be a reason.

Germinating Nasturtium seeds indoors
Nasturtium seeds can be germinated indoors in a propagator or soil. You can start the seeds four to six weeks before your desired planting date. When planting Nasturtium seeds, cover them with soil and water them well. Germination usually takes around 7 to 14 days. Once the seedlings emerge, they should be hardened off by keeping the temperature at around 15°C for a couple of weeks. Once the plants are hardy off, they can be moved into their garden space. Nasturtiums do best to grow in loose, well-drained soil that is pH 5.5 to 6.0.
Best time to harvest Nasturtium flowers
This depends on the climate your area experiences and the phase of growth of the plants. In most cases, harvesting Nasturtium when it is in its peak bloom will produce the highest quality flowers. Nasturtium typically blooms from May to July in temperate climates but can flower anytime in warmer climates. To ensure a bountiful harvest, start harvesting Nasturtium as soon as they bloom and continue until all blooms have been picked.
Planting Nasturtium seeds
First, choose a sunny location where the soil is moist and fertile. Secondly, sow the seeds 1 to 2 inches deep and water them regularly. Once the seedlings have rooted themselves, thin them out so that there are about 8 to 10 plants per pot. Finally, fertilize the plants once they reach 6 to 8 inches tall with a balanced fertilizer or emulsion mixture every two weeks during the summer months.

Pruning for Nasturtiums
- To produce the best Nasturtium plants, you’ll need to pay close attention to their pruning. Pruning should be done in early spring when the plants are just starting to grow. Start by trimming off any long, spindly branches and dead wood. Then, remove any flowers that have developed and any smaller side branches that may be growing in between the flowers. Finally, cut off the main stem 2 to 3 inches below the soil surface.
- Deadheading means removing flowers from plants to maintain a healthy crop. Deadheading Nasturtium plants will help to prevent flowering and promote the prolific production of seed pods. Prune off the oldest flower heads on Nasturtium plants, as they will become senescent and may not produce viable seeds. Be careful not to kill the younger leaves on the plant; cutting them too close to the main stem can cause them to die. Finally, ensure to keep all flowers from a single cluster. Doing so can lead to lopsided growth and reduced yield.
Harvesting Nasturtium flowers
Nasturtiums add beauty to any garden and can be grown from seed. Start by planting the Nasturtium seeds in early spring, before the soil has dried. Make sure to give the seeds plenty of water, then monitor their growth regularly. When the flowers have formed, you can start harvesting Nasturtiums by cutting at the base of the stem.
You can easily grow Nasturtium from seed, and they produce colorful flowers that can be used as a flower bouquet. Select a suitable variety for your climate and soil type to grow Nasturtium from seed. Seeds should be planted at the beginning of spring and need water and fertilizer regularly throughout their growth cycle. When the plants have grown tall enough, they can be harvested by picking the flowers or cutting the stem near the ground. Enjoy the bright colors and sweet flavor of Nasturtium flowers.
