Grow Flowers: Nasturtiums - The Easiest Annuals
With their cheerful blooms and trailing vines, nasturtiums make for an effortless addition to any garden. Whether you’re a seasoned gardener or just starting out, these easy-to-grow annuals are sure to impress.
Choosing the Perfect Spot
Nasturtiums thrive in full sun and well-drained soil. They’re not picky about soil quality, but they do prefer sandy or light textures. So, don’t worry about amending the soil excessively.
Sowing Seeds and Starting Young
Starting nasturtiums from seeds is a breeze. Just pop them into biodegradable pots indoors a few weeks before the last frost. This helps prevent root shock when transplanting outdoors.
Transplanting Outdoors
Once the weather warms and the soil temperature reaches 55-60°F, it’s time to transplant your seedlings. Space them 12-18 inches apart and water well. They’ll quickly establish themselves and start sending out vines.
Maintenance and Care
Pruning:
Occasional pruning or deadheading encourages new flower growth. If your nasturtiums get lanky, don’t hesitate to prune them back by up to half. This promotes bushier, more compact plants.
Fertilizing:
These low-maintenance plants don’t require much feeding. Avoid fertilizing them, as it can actually reduce flowering.
Watering:
Water your nasturtiums regularly, especially during hot, dry weather. Allow the soil to dry out slightly between waterings.
Harvesting and Uses
Edible Delights:
Both the flowers and leaves of nasturtiums are edible. Add their peppery flavor to salads, sandwiches, or as garnishes.
Pest Repellent:
These plants act as natural pest repellents, deterring aphids and other insects.
So, there you have it! Growing nasturtiums is as easy as 1-2-3. With their vibrant colors and versatility, these cheerful blooms are sure to add beauty and flavor to your garden.

Nasturtium Care Tips
If you seek the easiest and most rewarding annual flowers to nurture, look no further than the vibrant and versatile nasturtium! These low-maintenance blooms are a joy to grow in any garden, adding a splash of color and a touch of edible delight. To ensure their thriving growth, follow these Nasturtium Care Tips:
Light Requirements
Nasturtiums thrive in bright, direct sunlight. Aim for at least 6 hours of sunlight daily to encourage abundant blooms and healthy foliage.
Soil and Watering
They prefer well-drained soil that’s slightly acidic to neutral. Water them regularly, especially during dry spells, but avoid overwatering. Let the soil dry slightly between waterings to prevent root rot.
Feeding
Fertilizing nasturtiums is generally not necessary. Overfertilization can lead to excessive foliage growth and fewer flowers. However, if you notice yellowing leaves, a light application of a balanced fertilizer can help.
Pruning
Regular deadheading (removing spent blooms) encourages the plant to produce more flowers. Additionally, you can prune back lanky branches by half to promote a bushier, more compact shape.
Potting and Repotting
Nasturtiums thrive in pots or containers with good drainage. When repotting, choose a container that’s slightly larger than the current one and use fresh potting mix.
Troubleshooting
- Yellowing Leaves: Indicates nutrient deficiency. Fertilize lightly.
- Leggy Growth: Insufficient sunlight. Prune and relocate to a sunnier spot.
- Powdery Mildew: A fungal disease. Treat with a fungicide or neem oil.
Key Takeaways:
- Light: 6+ hours of bright sunlight
- Soil: Well-drained, slightly acidic to neutral
- Water: Regular watering, avoid overwatering
- Fertilizer: Not generally necessary, light feeding if needed
- Pruning: Deadhead and prune to promote flowering
