Proper Planting Techniques

1.1 Choosing the Right Location

When planting nasturtiums, it is important to choose a location that receives ample sunlight. Nasturtiums thrive in full sun, so look for a spot in your garden that gets at least 6-8 hours of direct sunlight per day. Additionally, make sure the area has well-draining soil to prevent waterlogged roots.

1.2 Preparing the Soil

Before planting your nasturtiums, it is essential to prepare the soil properly. Nasturtiums prefer slightly acidic to neutral soil with a pH level of around 6.0-7.0. You can improve the soil quality by adding compost or organic matter to provide nutrients for the plants.

1.3 Planting Depth and Spacing

When planting nasturtium seeds, sow them about 1 inch deep in the soil. Be sure to space the seeds or seedlings 8-12 inches apart to allow for proper air circulation and prevent overcrowding. This will help the plants grow healthy and vigorous, promoting better flowering and overall growth.

2. Watering and Fertilizing Tips

2.1 Watering Frequency

To ensure the proper growth of your nasturtiums, it is essential to maintain a consistent watering schedule. Nasturtiums prefer moist soil, so make sure to water them regularly, especially during hot and dry periods. However, be cautious not to overwater, as this can lead to root rot and other issues. A good rule of thumb is to water your nasturtiums when the top inch of soil feels dry to the touch.

2.2 Fertilizing Nasturtiums

Nasturtiums are not heavy feeders, but they can benefit from a balanced fertilizer to promote healthy growth and vibrant blooms. A general-purpose liquid fertilizer can be applied every 2-4 weeks during the growing season. Make sure to follow the instructions on the fertilizer package and avoid overfertilizing, as this can result in excessive foliage growth at the expense of flowers.

2.3 Avoiding Overwatering

While it is important to keep your nasturtiums adequately watered, it is equally crucial to avoid overwatering. Overwatering can lead to waterlogged soil, which can suffocate the roots and promote disease. To prevent overwatering, make sure that your pots have proper drainage holes and allow excess water to escape. Additionally, always check the moisture level of the soil before watering and adjust your watering schedule accordingly.

3. Pruning and Deadheading

3.1 Benefits of Pruning

Pruning is an essential practice when it comes to growing healthy and vibrant nasturtiums. By removing dead or damaged foliage, you not only improve the plant’s overall appearance but also promote new growth. Pruning also helps prevent the spread of diseases and pests, keeping your nasturtiums thriving.

3.2 How to Deadhead Nasturtiums

Deadheading is the process of removing faded or wilting flowers from your nasturtium plants. This encourages the plant to produce more blooms and prevents it from going to seed prematurely. To deadhead nasturtiums, simply pinch off the old flowers at the base of the stem using your fingers or pruners.

3.3 Timing for Pruning and Deadheading

It is best to prune nasturtiums regularly throughout the growing season to maintain their shape and encourage new growth. Deadheading should be done as soon as the flowers start to fade, typically every few days. By staying on top of pruning and deadheading, you can ensure that your nasturtiums continue to bloom beautifully all season long.

4. Dealing with Pests and Diseases

4.1 Common Pests to Watch Out For

Nasturtiums are generally hardy plants, but they can still fall victim to a few common pests. Keep an eye out for aphids, caterpillars, and slugs, as these are the most common pests that tend to attack nasturtiums.

4.2 Natural Pest Control Methods

Instead of resorting to harsh chemicals, consider using natural pest control methods to protect your nasturtiums. You can introduce beneficial insects like ladybugs or lacewings to your garden, as they feed on aphids and caterpillars. You can also try spraying a mixture of neem oil and water on your plants to deter pests.

4.3 Recognizing and Treating Diseases

Nasturtiums are susceptible to a few diseases, such as powdery mildew and bacterial leaf spot. Keep an eye out for any signs of yellowing or wilting leaves, as this could indicate a disease. To treat diseases, make sure to remove any infected plant material and improve air circulation around your plants. You can also try spraying a mixture of baking soda and water on your plants to help prevent the spread of diseases.

5. Harvesting and Seed Saving

5.1 When to Harvest Nasturtiums

When it comes to harvesting nasturtiums, timing is key. The best time to harvest nasturtium flowers is in the morning, just after the dew has dried. This is when the flowers are at their peak freshness and flavor. Avoid harvesting flowers that are wilted or discolored, as they may not have as strong of a flavor. For nasturtium leaves, they can be harvested at any time once the plant has established itself and has a good amount of foliage.

5.2 Seed Saving Techniques

To save seeds from your nasturtium plants, wait until the flowers have wilted and the seed pods have formed. The seed pods will be green at first, but will eventually turn brown and dry out. Once the seed pods are dry, carefully remove them from the plant and break them open to extract the seeds. Allow the seeds to dry completely before storing them.

5.3 Storing Nasturtium Seeds

To store nasturtium seeds, place them in a dry, cool place in an airtight container. Make sure the container is labeled with the date and type of seed. Properly stored nasturtium seeds can last for up to 2 years, so you can enjoy your favorite nasturtium varieties for multiple growing seasons.


In conclusion, these propagation hacks for nasturtiums are tried and tested methods that have been proven to work effectively. By following these tips and tricks, you can easily propagate your nasturtium plants and enjoy a bountiful harvest of beautiful flowers all season long. Whether you choose to propagate through seeds, cuttings, or division, there is a method that will work best for you and your garden. So don’t be afraid to experiment and try out different techniques to see what works for you. Happy gardening!
