Nasturtium seeds are easy to grow and do not require a lot of coddling. They can be grown indoors or outdoors, but some varieties can be tricky to germinate indoors. To grow nasturtium seeds, cover them with 1/4 inch of fine soil and ensure the soil is moist. Nasturtium seeds should be planted 1/2-1 inch deep and about 8 to 12 inches apart. They should be planted in an area that receives plenty of sun and has well-drained soil.

Nasturtium seeds should be covered with a thin layer of soil
Nasturtium seeds should be planted 1/2-1 inch deep and spaced about 8 to 12 inches apart. They can be covered with a thin layer of fine soil or compost. To promote germination, it is recommended to soak the seeds in warm water for 24 hours before planting. The seeds should then be planted immediately and covered with a thin layer of soil. Nasturtiums prefer well-drained soil and full sun, so ensure they are planted in an area that receives at least 6 hours of direct sunlight per day.
When transplanting nasturtium seedlings, it is important to take care not to disturb the roots. Make a hole in the soil that is twice the size of the root ball and fill it with water. Carefully slide the moist root ball out of the pot and place the seedling in the hole so that the roots are at the same depth in the soil. Press the wet soil around the root ball and water it well.
Nasturtiums are sensitive to frost, so it is important to wait until the danger of frost has passed before planting the seeds or transplanting seedlings. They can tolerate a wide range of temperatures and are fairly carefree, but they prefer warm, sandy soils and cool summer temperatures. With the right conditions and a bit of patience, you can successfully grow nasturtiums from seeds.

Nasturtiums are easy to grow from seed
Nasturtiums are incredibly easy to grow from seed, making them ideal for beginner gardeners and children. They are also known as Indian cress and have large, easy-to-handle seeds.
Nasturtiums can be grown directly outdoors by simply pushing the seeds into the ground with your finger, or using a dibber to make holes just 1/2 inch deep and spaced 10 to 12 inches apart. They should be covered with a thin layer of compost or soil. Direct sowing is a good choice for nasturtiums as they don't require a lot of coddling, and seedlings can suffer from transplant shock. The seeds should be sown outdoors when the soil is warm, typically after the last frost date in your area. In Southern California, it is recommended to sow the seeds outdoors in late spring or early summer.
Nasturtium seeds can also be started indoors in pots to get earlier blooms. The seeds are large, so start with a relatively large 2-3/4" or 3" seed starting pot. To prevent transplant shock, try using a biodegradable container. Put two seeds (1" deep) in each pot and grow them under lights or in a bright location. It takes about 10 to 14 days for nasturtiums to germinate. When the seedlings have a few sets of leaves, pinch out the weaker seedling, leaving one per pot.
Nasturtiums have no specific soil requirements but prefer well-drained soil and full sun. They are drought-tolerant once established and can tolerate a wide range of temperatures. They are sensitive to frost, so care must be taken to plant them after the danger of frost has passed.

Nasturtium seeds can be soaked before planting to aid germination
Nasturtiums are described as easy to grow and "almost foolproof". They are relatively inexpensive and can be grown from seeds, making them ideal for beginner gardeners and children. The flowers, leaves, and seeds are edible and decorative, and they can be grown in a variety of garden spots, from partial shade to full sun. They also act as host plants for aphids, attracting them away from your other plants.
When it comes to planting nasturtium seeds, it is recommended to soak them before sowing to aid germination. Soaking the seeds in warm water for 12 to 24 hours helps soften the seed coating and gives the embryo a chance to emerge. This process increases the likelihood of successful germination and can be especially useful if you are experiencing dry weather conditions.
Direct sowing is a popular method for planting nasturtium seeds. This technique involves planting the seeds directly where you want them to flower. To do this, rake the soil to a fine tilth, ensuring it is free of weeds. Water the area before sowing to prevent washing away the seeds. Then, create holes about 1/2 inch deep and 10 inches apart, placing one seed per hole. Cover the seeds with fresh compost and keep the soil moist while waiting for germination, which typically occurs within 7 to 10 days.
Alternatively, you can start nasturtium seeds indoors to get larger plants and earlier blooms. Use a large seed-starting pot, about 2-3/4" or 3", and place two seeds 1 inch deep in each pot. Grow them under lights or in a bright location. When the seedlings develop a few sets of leaves, remove the weaker seedling, leaving one per pot. Once nighttime temperatures reach the 50s, you can harden off the seedlings before transplanting them outdoors in late spring.
Whether you choose to direct sow or start your nasturtium seeds indoors, remember that nasturtiums are sensitive to frost. Wait until the danger of frost has passed before planting outdoors, usually from March to May. Nasturtiums prefer well-drained soil and plenty of sun but have no specific soil requirements, making them adaptable to various growing conditions.

Nasturtium seeds can be planted directly outdoors
Nasturtiums are incredibly easy to grow from seed, making them ideal for beginner gardeners and children. They can be sown directly outdoors where they are to flower, without the need for plastic covering. This technique is known as "direct sowing".
To begin, prepare the soil by raking it to a fine tilth and ensuring it is free of weeds. Water the area before sowing to prevent seeds from washing away. Nasturtiums prefer well-drained soil, so make sure your garden plot has good drainage. They also prefer full sun, so choose a location that receives at least 6 hours of direct sunlight per day.
When the soil is ready, simply push the seeds into the ground with your finger or use a dibber to make holes. Nasturtium seeds should be planted about 1/2-1 inch deep and spaced about 8 to 12 inches apart. Cover the seeds with fine soil, ensuring they are not disturbed once transplanted.
Keep the soil moist while waiting for germination, which typically occurs within 7 to 14 days. With the right conditions and a bit of patience, you should successfully grow nasturtiums from direct sowing outdoors.

Nasturtium seeds should be planted in well-drained soil
Nasturtiums are incredibly easy to grow from seed, making them ideal for beginner gardeners and children. They are either bushy or dwarf (Tropaeolum minus) or climbers (Tropaeolum majus). Bushy varieties look great in containers and hanging baskets or at the front of a border, while climbing varieties can be trained up wigwams or obelisks and will twine through other plants. They can also be used as ground cover, spreading across gravel or cascading down a slope or bank. Both types grow very well in pots.
Nasturtiums have no specific soil requirements; just be sure it is a well-drained area that receives plenty of sun. Nasturtiums prefer warm sandy soils, cool summer temperatures, and like to be planted where they will remain for the whole season. They are very sensitive to frost and are not frost-hardy. They prefer full sun, so make sure they are planted in an area that receives at least 6 hours of direct sunlight per day.
Nasturtium seeds should be planted 1/2-1 inch deep and about 10 inches apart. You can sow nasturtium seeds directly where they are to flower. Rake the soil to a fine tilth and make sure it is free of weeds. Water the area before you sow – this will ensure that you don't wash away the seeds once sown. You can also sow nasturtium seeds in pots – this is a good way to get earlier flowers and is a good option if you want to plant a beautiful container display later in the season.
If you want to start with larger plants and get earlier blooms, start the seeds indoors. Nasturtium seeds are large, so start with a relatively large 2-3/4" or 3" seed-starting pot. To prevent transplant shock, try using a biodegradable container. Put two seeds (1" deep) in each pot and grow them under lights or in a bright location, such as a south-facing window. It takes about 10 to 14 days for nasturtiums to germinate. When the seedlings have a few sets of leaves, pinch out the weaker seedling, leaving one per pot.
