Method: Water from the base of the plant to prevent wetting the leaves and causing fungal disease. Avoid overhead watering.	Type: Use an all-purpose fertilizer, such as a 10-10-10 ratio, or a low-nitrogen option like bone meal. Too much nitrogen can cause excessive growth and reduced flowering.

Remember to also keep an eye on soil conditions; nasturtiums prefer well-draining soil and may suffer if overwatered. By following these watering and fertilizing tips, you can help your nasturtiums thrive and achieve their full potential.

Nasturtium Pests and Diseases

Despite being relatively disease-resistant, nasturtium plants can still fall prey to a few common pests and diseases. While prevention is always the best course of action, it’s good to know how to identify and treat any issues that may arise. Here are some best practices for nasturtium care to help you keep your plants healthy:

Common Nasturtium Pests

Although nasturtiums are often touted as natural pest repellents, a few insects may still cause damage to your plants. Here are some of the most common nasturtium pests:

Pest	Symptoms	Treatment
Aphids	Tiny green or black insects clustered on the leaves or stems. They may cause yellowing or wilting of the affected plant parts.	Wash the leaves with a strong spray of water. You can also try applying insecticidal soap or neem oil to deter the pests.
Cabbage looper	Green caterpillars that may chew holes in the leaves or bore into the buds. You may also see their droppings on the leaves.	Pick off the caterpillars and dispose of them. You can also dust the plants with Bacillus thuringiensis (Bt) or spinosad to control the pests.
Whiteflies	Tiny white insects that fly off in a cloud when disturbed. They may cause yellowing or stunted growth of the plants.	Hang sticky traps around the plants to catch the whiteflies. You can also use insecticidal soap or neem oil to kill the pests.

Common Nasturtium Diseases

Nasturtiums are generally resistant to most plant diseases, but they may still develop a few issues. Here are some of the most common nasturtium diseases:

• Leaf spot: This fungal disease causes brown or black spots on the leaves. It may also cause defoliation if left untreated.
• Rust: This fungal disease causes orange or brown spots on the leaves, stems, or flowers. It may also cause premature drop of the affected plant parts.
• Mildew: This fungal disease causes a white or gray powdery coating on the leaves or stems. It may also cause distortion or stunted growth of the plants.

To prevent and treat these diseases, make sure to keep your plants well-spaced and watered at the base. Avoid overhead watering and remove any affected plant parts promptly. You can also apply a copper-based fungicide according to the manufacturer’s instructions.

Nasturtium Pruning and Deadheading

To maintain healthy nasturtium plants, pruning and deadheading are crucial. Regular pruning of the leaves and stems promotes air circulation, which prevents the growth of fungi and other diseases. Deadheading, the process of removing spent flowers, also encourages the plant to produce more blooms.

To prune nasturtiums, wait until the plant is at least six inches tall. Then, use clean, sharp pruning shears to cut back any dead or damaged leaves and stems. Be careful not to cut off too much, as this can damage the plant.

Deadheading can be done as soon as the flowers fade and wilt. Use your fingers or snips to remove the entire flower and its stem. This will prevent the plant from using valuable energy to produce seeds and instead encourage the growth of new flowers.

Regularly pruning and deadheading will keep your nasturtiums healthy and blooming all season long. Follow these tips for nurturing your plants, and you’ll be rewarded with a beautiful and vibrant garden.

Nasturtium Trellising and Support

When it comes to growing nasturtiums, trellising and support can be incredibly helpful for maximizing the growth potential of these beautiful plants. Best practices for nasturtium care dictate that providing plants with the right support structure ensures they grow vertically, revealing their gorgeous foliage and flowers to full effect.

One of the easiest ways to support nasturtiums is by installing a trellis. This vertical structure made of wood or metal provides a framework for the plants to grow up against. To use a trellis, simply plant the nasturtiums at the base and then train them to climb the structure as they grow. As they reach the trellis, guide the stems gently to keep them upright and prevent breakage.

If you don’t have access to a trellis, there are other ways to support your nasturtium plants. One option is to use stakes and twine to create a simple support structure. To do this, drive a stake into the ground next to the plant and then tie a piece of twine to the stake. Gently wrap the twine around the plant stem and tie it in place, being careful not to damage the stem or foliage.

It’s important to note that nasturtiums typically grow quite quickly and can become top-heavy if not properly supported. By providing them the right structure, you can ensure that they continue to grow healthy and strong throughout the season.

Harvesting Nasturtium Flowers and Leaves

Harvesting nasturtium plants is a delightful activity, but it’s important to do it at the right time to ensure peak flavor and freshness. Here are some expert tips for cultivating nasturtium plants:

• Method: Use clean, sharp scissors or pruning shears to cut the stems of nasturtium flowers or leaves. Cut the stem close to the base of the plant, but be sure not to damage the adjacent leaves or flowers.
• Storage: Nasturtium flowers and leaves can be stored in an airtight container in the refrigerator for up to a week. Alternatively, you can preserve them by drying them in a cool, dry place away from direct sunlight.
• Culinary Uses: Nasturtium flowers and leaves have a peppery, slightly sweet flavor that makes them an excellent addition to salads, sandwiches, and other dishes. They can also be used to make a flavorful herbal tea or a vinegar infusion.

With these tips, you can enjoy the delicious flavor and versatility of nasturtiums in your favorite recipes. Happy harvesting!

Overwintering Nasturtiums

If you live in a region with harsh winters, it’s essential to take measures to protect your nasturtium plants from frost and freezing temperatures. With the right care, you can ensure that your plants survive the winter and thrive again in the spring.

One important step in overwintering nasturtiums is to cut back the foliage after the first frost. This will help prevent disease and pests from overwintering in the plant’s remains.

Another key consideration is to provide a protective covering for the plants. You can use a layer of mulch, straw, or other organic material to insulate them from the cold. Alternatively, you can cover them with a frost blanket or fabric cover to shield them from freezing temperatures.

It’s also important to reduce watering frequency and volume during the winter months. While the soil should not dry out completely, the plants require less moisture during the dormant period to avoid root rot or fungal diseases.

In the spring, remove the protective covering and prune any dead or damaged branches. Resume normal watering and fertilizing schedules and watch as your nasturtium plants come back to life with renewed vigor and beauty.

By following these tips for maintaining healthy nasturtiums during the winter months, you can enjoy their vibrant colors and delicious flavors year after year.

Propagating Nasturtium Plants

Nasturtiums are easy to propagate, and you can grow them from seed, stem cuttings, or division. Whichever method you choose, make sure to follow these tips for the best results.

Growing Nasturtiums from Seeds

To grow nasturtiums from seeds, start by preparing the soil. It should be loose, well-drained, and enriched with compost or organic matter. Sow the seeds directly into the soil after the last frost date in your area. Make sure to space them about 10-12 inches apart and cover them with a thin layer of soil.

Water the seeds gently and keep the soil moist until the seeds germinate in 7-10 days. Once the seedlings have two sets of leaves, thin them out, leaving the strongest ones spaced at least 12 inches apart. Fertilize them once a month with a balanced fertilizer, and water them deeply once a week or as needed.

Tips for Nurturing Nasturtium Plants

If you want to propagate nasturtiums from stem cuttings, choose a healthy, non-flowering stem and cut it just below a node. Remove the lower leaves and dip the cut end into rooting hormone. Plant it in a pot with well-draining soil and place it in a bright, warm location. Keep the soil moist and mist the leaves regularly. In a few weeks, the cutting should take root and develop new leaves.

Another way to propagate nasturtiums is by division. Dig up an established plant in early spring or fall and separate it into smaller clumps with a sharp knife or shovel. Replant each clump in a new spot and water it well. This method is ideal for rejuvenating old or overgrown nasturtiums.

Whichever method you choose, remember to give your nasturtiums plenty of sun, water, and good soil. With proper care, they will reward you with a profusion of colorful blooms and leaves.
