Soaking seeds in water overnight prior to planting may speed germination, but nasturtium seeds sprout best when the soil is warm. The seeds should be put in the soil at a depth of 3 inches and a width of 1 inch.
Plant seedlings in a well-drained potting mix and allow them to grow until they reach a height of at least 3 feet (1.2 m) and a diameter of 1 foot (305 mm). Seedlings should be allowed to dry out completely before transplanting into a larger pot.

Should I start nasturtium seeds indoors?
Nasturtium seeds may be sown directly in the garden (recommended) or started indoors. We prefer to direct-sow them because of their fragile roots. Start seeds 2 to 4 weeks before your last frost date indoors. Sow the seeds in a well-drained pot with a few inches of organic mulch between the soil and the potting mix.
The seeds will germinate within a week or two, depending on the temperature and humidity in your area. If you’re planting indoors, you’ll need to water the seedlings regularly to keep them from drying out. You can also add a little bit of compost to the mix to help keep the roots moist.
Keep in mind that sowing sesame seeds indoors can be a bit tricky, as they need a lot of light and moisture in order to sprout. It’s best to wait until the last day of the growing season before you plant them outdoors.
How long does it take nasturtium seeds to germinate?
Before the last frost date, sow indoors in coir pots. You can direct sow from 1 week after the last frost to 2 weeks into the early summer. Seeds will sprout in 7-12 days, perhaps sooner if the soil is warm and moist. Plant seedlings in a well-drained pot with good drainage and a good-sized hole in the bottom of the pot.
The hole should be at least 1/2″ deep and 3/4″ in diameter. If the hole is too small, the seeds will not germinate and you will have to start again from the beginning with a larger hole. Seedlings should not be allowed to dry out, as this will cause the seed to rot and the plant to wilt and die.
Water well, but not so much that it dries out the roots. Do not water more than once or twice a week, and do not allow the plants to sit in water for long periods of time. This will prevent the root system from developing properly and will result in poor plant growth and poor yields. Allow the pots to air-dry between waterings.
Do nasturtium seeds need light to germinate?
If you want to plant Nasturtium seeds deep in the pots, you need to plant them 1/2- to 1-inch deep. Keeping the soil temperature close to 70 degrees encourages quick growth. The nasturtium seedlings won’t require light until they are about 3 inches tall.
The seeds germinate in about two weeks, and the plants are ready to harvest in two to three weeks. Harvesting the plant is easy, as long as you don’t over-harvest. If you do, you’ll have to replant and start over.
What month do you plant nasturtium seeds?
When the soil has warmed up from march to may a late sowing of nasturtium seeds will ensure that the seeds grow. Sow seedlings in the spring after the last frost date. This will give the plants a chance to establish themselves before the next frost. If you sow seeds in late spring or early summer, you will need to wait until the following spring to plant them.
How do you start a nasturtium indoors?
Put two seeds (1″ deep) in each pot and grow them under lights or in a bright location, such as a south-facing window. nasturtiums take about 10 to 12 days to grow. When the seedlings have a few sets of leaves, pinch out the weaker one and leave the stronger one to grow.
Plant the seeds outdoors in the spring or early summer, when the weather is warm and the soil is moist. They will take about a year to reach full size, but they will be ready to harvest in two to three years.
Do nasturtium seeds need stratification?
Large or hard seeds like those of beans, okra, and nasturtium often require scarification for optimal germination. Plants in the tomato and morning glory families have impermeable seed coats and will only grow if they are exposed to light and air. The seeds of many plants, such as tomatoes, peppers, cucumbers, eggplants, etc., can be eaten raw or cooked in a variety of ways.
The most common way to eat the seeds is to cut them in half lengthwise and place them on a paper towel to soak for a few minutes. They can also be soaked in water for several hours and then placed on paper towels to dry.
If you want to cook them, you can either soak them overnight in boiling water, or boil them for about 10 minutes in salted water. You can use either of these methods if you don’t have a dehydrator, but you will need to make sure that the water you use is not too hot or too cold.
Do nasturtiums come back every year?
Nasturtiums have a long flowering period until the first frosts of autumn. Nasturtiums are either annuals or perennials and can be low-growing bushy plants. Plants in the family Asteraceae are often used as ornamental plants in gardens and landscapes. They are native to Europe, Asia and North America, and have been used for thousands of years to decorate and beautify the landscape.
