When it comes to adding color and beauty to your garden, there are few flowers that can compare to nasturtiums. These vibrant and versatile plants come in an array of bright colors, making them a popular choice for gardeners all over the world.

One of the best things about nasturtiums is that they are incredibly easy to grow from seeds. Whether you are a seasoned gardener or a beginner, you can enjoy the beauty of nasturtiums in your own garden with just a little bit of effort.

To get started, choose a sunny spot in your garden where the soil is well-draining. Nasturtiums prefer full sun, which means they need at least six hours of direct sunlight each day to thrive. If you have heavy soil, consider adding some compost to improve drainage.

When it comes to sowing the seeds, you can either start them indoors a few weeks before the last frost date or sow them directly into the ground once all danger of frost has passed. If you choose to start them indoors, use peat pots or seed trays filled with seed-starting compost. Sow the seeds thinly and cover them with a thin layer of compost.

Once the seeds have germinated and the danger of frost has passed, you can transplant them into the garden. Make sure to space them at least 12 inches apart to allow for adequate airflow and prevent the spread of diseases. Nasturtiums can also be grown in containers and hanging baskets, making them a great choice for small gardens and balconies.

If you want to enjoy continuous blooms throughout the summer, deadhead the flowers regularly. This involves removing the spent flowers to encourage the plant to produce more blooms. Nasturtiums are also quite tolerant of neglect, making them a great choice for busy gardeners.

Choose the Right Variety for Your Garden

When it comes to choosing the right variety of nasturtiums for your garden, there are several factors you should consider. Nasturtiums come in a variety of colors, sizes, and growth habits, so it’s important to choose a type that will thrive in your specific growing conditions.

Color

Nasturtiums are known for their vibrant flowers, which come in shades of red, orange, yellow, and sometimes even pink or cream. Consider the color palette of your garden and choose a variety that complements the other plants and adds visual interest.

Size

Nasturtiums can range in size from compact varieties that are perfect for containers or small spaces, to sprawling vines that can climb up trellises or fences. Think about the available space in your garden and choose a variety that will fit well and not overcrowd other plants.

Growth Habit

Some nasturtiums have a more bushy growth habit, while others are more trailing or climbing in nature. Think about the overall aesthetic you want to achieve in your garden and choose a variety that will complement your desired style.

Edible Varieties

In addition to their beautiful flowers, nasturtiums also have edible leaves and flowers that add a spicy, peppery flavor to salads, sandwiches, and other dishes. If you’re interested in using nasturtiums in your culinary creations, look for edible varieties specifically bred for their flavor.

Sunlight and Soil Requirements

Finally, consider the sunlight and soil requirements of the different nasturtium varieties. Some varieties prefer full sun, while others can tolerate partial shade. Additionally, nasturtiums generally prefer well-drained soil, so if you have heavy clay soil, you may need to amend it with organic matter before planting.

By considering these factors and choosing the right variety of nasturtiums for your garden, you’ll be well on your way to growing beautiful flowers from seed. Whether you want to add a burst of color to your flower beds, create a charming container display, or have a tasty addition to your summer meals, nasturtiums are a great choice for any garden.

Prepare the Soil for Planting

Before planting nasturtium seeds, it’s important to prepare the soil to ensure optimal growing conditions for the flowers.

1. Choose a Sunny Spot: Nasturtiums thrive in full sun, so select a location in your garden that receives at least 6-8 hours of direct sunlight each day.

2. Clear the Area: Remove any weeds or grass from the planting area to prevent competition for nutrients and space.

3. Loosen the Soil: Use a garden fork or tiller to loosen the soil to a depth of about 6-8 inches. This will improve drainage and make it easier for the roots to spread.

4. Amend the Soil: If your soil is heavy or clay-like, it’s beneficial to mix in organic matter such as compost or well-rotted manure to improve its texture and fertility.

5. Test the pH: Nasturtiums prefer slightly acidic soil with a pH between 6.0 and 7.0. If your soil is outside of this range, you can adjust the pH by adding lime to raise it or sulfur to lower it.

6. Level the Soil: Rake the soil to create a smooth and level surface for planting. This will ensure an even distribution of water and nutrients to the plants.

7. Water the Soil: Before sowing the seeds, thoroughly water the soil to provide moisture for germination.

8. Install Supports (Optional): If you plan to grow climbing or trailing varieties of nasturtiums, you may need to install trellises, cages, or stakes for the plants to climb or drape over.

9. Consider Companion Plants: Nasturtiums are known for their ability to repel pests, so consider planting them near susceptible plants like tomatoes or cabbage to deter pests naturally.

By taking the time to properly prepare the soil, you can give your nasturtium seeds the best chance of germinating and growing into beautiful flowers.

Sow the Seeds at the Right Time

Timing is crucial when it comes to sowing nasturtium seeds. These plants thrive in warmer weather, so it’s best to sow the seeds after the last frost date in your area. This will ensure that the soil temperature is ideal for germination and growth.

Typically, nasturtium seeds can be sown directly into the garden soil. They have a hard seed coat, so it’s recommended to soak the seeds in water for a few hours before planting. This will help soften the seed coat and promote better germination.

Choose a sunny location in your garden for sowing the seeds. Nasturtiums prefer full sun but can tolerate some light shade. Prepare the soil by removing any weeds and loosening it with a garden fork or tiller. Rake the soil smooth and create shallow furrows for planting the seeds.

Plant the soaked nasturtium seeds about 1 inch deep and 6 inches apart. Space the furrows about 12 inches apart. Cover the seeds with soil and gently firm it down. Water the area well to ensure good seed-to-soil contact and keep the soil evenly moist.

It’s important to note that nasturtiums are not frost tolerant, so avoid sowing the seeds too early in the spring if there’s still a risk of frost. Conversely, if you live in a region with hot summers, it’s best to sow the seeds in early spring or late summer to avoid the extreme heat.

By sowing nasturtium seeds at the right time, you’ll give them the best chance of thriving and producing beautiful flowers in your garden.

Provide the Ideal Growing Conditions

When it comes to growing nasturtiums from seed, providing the ideal growing conditions is essential to ensure beautiful and healthy flowers. Here are some tips to create the perfect environment for your nasturtiums:

1. Sunlight

Nasturtiums thrive in full sunlight. Choose a location in your garden that receives at least 6 to 8 hours of direct sunlight each day. This will help promote healthy growth and vibrant flowers.

2. Soil

These flowers prefer well-draining soil with a pH level of 6.0 to 7.5. Before planting the seeds, amend the soil with organic matter such as compost or aged manure to improve its fertility and drainage.

3. Watering

While nasturtiums are relatively drought-tolerant, they still require regular watering, especially during dry spells. Water them deeply, allowing the soil to become slightly dry between watering sessions. Avoid over-watering, as it can lead to root rot.

4. Temperature

Nasturtiums are warm-season plants and prefer temperatures between 60°F (15°C) and 70°F (21°C). Plant the seeds after the danger of frost has passed and the soil has warmed up. Provide frost protection if needed.

5. Fertilizer

These flowers are not heavy feeders and thrive in moderately fertile soil. Applying a balanced fertilizer once or twice during the growing season is usually sufficient. Avoid using high-nitrogen fertilizers, as they can promote foliage growth at the expense of flower production.

6. Companion Planting

Nasturtiums are great companion plants as they deter pests such as aphids and whiteflies from attacking neighboring plants. Consider planting nasturtiums alongside vegetables or other ornamental plants to provide natural pest control.

By providing the ideal growing conditions, you can ensure that your nasturtiums grow beautifully, producing an abundance of colorful flowers that will brighten up your garden.

Water and Feed Regularly

Nasturtiums are not particularly thirsty plants, but proper watering is important for their overall health and growth. Here are some tips to help you water your nasturtiums:

1. Watering Schedule

Water your nasturtiums regularly, particularly during dry periods. Aim to keep the soil evenly moist, but not soggy. Avoid overwatering, as this can lead to root rot.

2. Watering Technique

When watering, give the plants a deep soak rather than a quick splash. This will encourage the roots to grow deeper into the soil. Use a watering can or a gentle stream from a hose to ensure thorough watering.

3. Watering Frequency

The frequency of watering will depend on various factors such as weather conditions, soil type, and the size of your containers or garden beds. Generally, watering once or twice a week should be sufficient. However, during hot, dry weather, you may need to water more frequently.

4. Feeding Nasturtiums

Nasturtiums are relatively low-maintenance plants and do not require much fertilization. However, you can give them a boost by feeding them with a balanced fertilizer once a month. Choose a fertilizer that is low in nitrogen, as high levels of nitrogen can promote leafy growth rather than flower production.

5. Organic Fertilizers

If you prefer to use organic fertilizers, you can feed your nasturtiums with compost or well-rotted manure. These natural fertilizers provide nutrients to the soil and help improve its structure over time.

6. Fertilizing Containers

If you are growing nasturtiums in containers, they may require more frequent feeding. Container-grown plants rely on the nutrients present in the potting mix, which can deplete over time. Feed them with a water-soluble fertilizer every two weeks to ensure they stay healthy and vibrant.

By following these watering and feeding tips, you can ensure that your nasturtiums grow into beautiful, flourishing plants that will add vibrant colors to your garden.

Control Pests and Diseases

Like any other plant, nasturtiums can be susceptible to pests and diseases. However, with proper care and prevention measures, you can keep these issues under control and ensure your nasturtiums grow beautifully. Here are some tips to help you control pests and diseases:

1. Aphids
