Nasturtiums are vibrant and easy-to-grow flowers that can brighten up any garden during the summer months. To enjoy their continuous blooms, gardeners need to follow some simple tips and techniques. This article provides practical advice on how to encourage your nasturtiums to bloom all summer long.
Choosing the Right Nasturtium Varieties
Start by selecting varieties known for their prolific blooming. Popular options include ‘Jewel of Africa,’ ‘Empress of India,’ and ‘Alaska.’ These varieties tend to produce abundant flowers throughout the season. Additionally, consider planting both climbing and bush types to diversify your garden display.
Proper Planting and Location
Nasturtiums thrive in full sun but can tolerate partial shade. Choose a location with well-draining soil to prevent root rot. Plant seeds directly into the ground after the last frost date, or start seedlings indoors for an earlier bloom. Space plants about 10-12 inches apart to allow good air circulation.
Watering and Fertilization
Keep the soil consistently moist but not waterlogged. Water deeply once a week, increasing frequency during hot, dry spells. Nasturtiums do not require heavy fertilization; too much fertilizer can lead to lush foliage with fewer flowers. If needed, use a balanced, diluted fertilizer sparingly.
Pruning and Deadheading
Regular deadheading encourages new blooms. Remove faded flowers by pinching or cutting just above the set of leaves. Pruning leggy or overgrown stems helps maintain a compact shape and promotes more flowering. For climbing varieties, guide vines onto supports to keep them healthy and productive.
Additional Tips for Continuous Blooms
- Plant in succession: sow new seeds every few weeks for a continuous supply of flowers.
- Mulch around plants to retain moisture and suppress weeds.
- Monitor for pests like aphids and caterpillars, and treat promptly.
- Avoid overwatering and excessive fertilization to prevent lush foliage at the expense of flowers.
By following these tips, you can enjoy a vibrant, colorful display of nasturtiums throughout the summer. Their cheerful blooms will add beauty and a splash of color to your garden season after season.
