How to Dry Nasturtium Seeds
How do you harvest and store nasturtium seeds?
How do you harvest and dry nasturtiums?
Do nasturtium seeds need to be scarified?
Large or hard seeds like those of beans, okra, and nasturtium often require scarification for optimal germination. Most plants in the tomato and morning glory families also have impermeable seed coats and will germinate better after scarification.
How do you know if nasturtium seeds are viable?
Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.
Will nasturtiums reseed themselves?
Nasturtiums flower best in cool weather and begin blooming within 60 days from seed. They may reseed themselves. The large seeds are easily handled and planted by small hands, so they make a good garden project for children. Nasturtiums don't transplant well, so plant them by seed directly into their permanent home.
How long does it take for nasturtium seeds to dry?
Allow the nasturtium seeds to dry until the seeds turn hard, brown and wrinkled. Shake the tray every day so the seeds will dry evenly. Drying may take two weeks or more.
Do nasturtiums grow back every year?
Nasturtiums have a long flowering period through summer until the first severe frosts of autumn. Nasturtiums are either annuals or perennials and can be low-growing bushy plants, trailing or even climbing. The perennial varieties are mostly winter/cold hardy, whereas the annuals have to be grown each year from seed.
How long are nasturtium seeds viable?
How long can you store nasturtium seeds? You can store nasturtium seeds for as long as you'd like, but when it pertains to viability, anticipate saving them for several years. Germination rates are better for younger seeds, but some nasturtium seeds may still sprout even if they're 3 to 5 years old, or possibly older.
What month do you plant nasturtium seeds?
Indoors: Start seeds 2 to 4 weeks before your last spring frost date. Outdoors: Sow seeds 1 to 2 weeks after your last spring frost date. Soil temperatures should ideally be between 55° and 65°F (12° and 18°C). Plan to protect young seedlings from late frosts.

Soaking seeds in water overnight prior to planting may speed germination, but nasturtium seeds sprout best when the soil is warm. Poke seeds into the soil about 1 inch (3 cm) deep and 3 inches (8 cm) apart.
What can I do with nasturtium pods?
Nasturtium seed saving is almost as easy as collecting the seeds. Just spread the seeds on a paper plate or paper towel and leave them until they're completely brown and dry. Ripe seeds will dry within a few days, but green nasturtium seeds will take much longer. Don't rush the process.
What do you do with dried nasturtium flowers?

Why won't my nasturtium seeds germinate?
The hard, dry seed coating on large nasturtium seeds can slow germination because it's difficult for water to soak into the seed and force it from dormancy. The University of Washington's Botanic Gardens suggests nicking or scarifying the seed coat and then soaking it in water to speed germination.
How do you start nasturtium seeds?
Sow indoors in peat or coir pots 2-4 weeks before the last frost date. Better yet, direct sow from 1 week after last frost and repeat at 2 week intervals into early summer. Optimal soil temperature for germination: 12-18°C (55-65°F). Seeds will sprout in 7-12 days, perhaps longer outdoors.
Will nasturtiums overwinter?
Nasturtiums Temperature Requirements
Hard freezes kill a nasturtium completely, so the only way a nasturtium will survive the winter in temperate climates is if you take it indoors or move it into a greenhouse before the first killing frost.
How do you train nasturtiums to climb?
Do nasturtiums need staking?
Plant immediately into a container or area of the garden which allows plenty of room for growth. You may place a trellis near the planting area of climbing nasturtium varieties and train the colorful vines to climb with little effort.

How fast do nasturtiums grow from seed?
After the seeds germinate, nasturtiums take between 35 and 52 days to flower, depending on the variety and growing conditions. Shorter varieties will begin to flower sooner than tall, rambling varieties, since tall varieties will undergo vegetative growth longer before producing flowers.

Why are my nasturtiums leggy?
If they have to reach for light, they may grow too rapidly. Excessive heat can also cause a burst in seedling growth, making them leggy, so avoid heating pads if they are warm enough in their starter trays. Also helpful in avoiding this early legginess is consistent moisture in the soil and proper spacing.
Are nasturtiums poisonous to dogs?

Sow indoors 4-6 weeks before the last frost using a seed starting kit. It is best to use a large celled kit, or fiber pots as nasturtium roots are easily damaged when transplanting.
What is seed notching?
Seed Starting Tips - Nicking Seeds
Nicking seeds is the process of opening the seed coat, or seed "jacket", prior to planting them. This process makes it easier for water to penetrate the seed coat, and reach the seed germ inside. Water penetration is one essential ingredient to begin the seed sprouting process.
What seeds should be soaked before planting?
