Nasturtium (Tropaeolum majus) is a vibrant and versatile plant that is not only beautiful but also serves multiple purposes in the garden. Known for its bright flowers and edible leaves, nasturtium is an excellent choice for Maryland gardeners seeking to enhance their landscape with color and functionality. This article will provide a comprehensive guide on how to grow nasturtium in Maryland, covering everything from choosing the right variety to planting, caring for, and utilizing your nasturtiums.
Nasturtiums are annual plants native to South America. They come in a variety of colors including orange, yellow, red, and even variegated forms. The flowers, leaves, and seeds of the plant are edible, making it a favorite among chefs and home cooks alike for garnishing salads and dishes. Nasturtiums can be grown in both garden beds and containers, making them an adaptable option for any garden setup.
When selecting nasturtium varieties for your Maryland garden, consider both the growing conditions you can provide and the intended use of the plants. Here are a few popular varieties:
Choose a variety based on your garden’s aesthetic needs as well as your culinary preferences.
Nasturtiums thrive in conditions that mimic their native environment. Here are the key factors to consider when creating the ideal growing conditions for nasturtiums in Maryland:
Maryland has a humid subtropical climate with warm summers and mild winters, which is quite favorable for growing nasturtium. However, it’s important to note that these plants prefer cooler temperatures; thus, late spring is typically the best time to plant them after the risk of frost has passed.
Nasturtiums prefer well-draining soil rich in organic matter. While they can tolerate poor soils, providing them with nutrient-rich soil will promote better growth and more vibrant blooms. Aim for a soil pH between 6.0 and 7.0.
These plants flourish in full sun but can tolerate partial shade as well. In Maryland’s hot summer months, some afternoon shade can help protect nasturtiums from wilting.
Nasturtiums require consistent moisture but do not like to sit in waterlogged soil. Water them regularly during dry spells while allowing the top inch of soil to dry out between watering sessions.
When it comes to planting nasturtium in Maryland, you have two primary methods: direct seeding and transplanting seedlings.
Timing: Sow seeds directly into the garden bed or container after the last frost date—typically late April or early May in Maryland.
Preparation: Prepare your chosen site by loosening the soil and mixing in compost or organic fertilizer.
Sowing: Plant seeds about half an inch deep and spaced 10-12 inches apart if planting multiple seeds together.
Watering: Water gently after sowing to settle the seeds into the soil.
Starting Seeds Indoors: If you want an earlier start, sow seeds indoors 4-6 weeks before the last frost date.
Transplanting Outdoors: Once seedlings have two sets of true leaves and outdoor conditions are suitable (after frost), transplant them into prepared garden beds or containers at the same spacing mentioned above.
Once planted, nasturtiums require minimal care but will benefit from consistent attention to certain aspects:
Apply a layer of mulch around your plants to help retain moisture, suppress weeds, and maintain soil temperature.
While nasturtiums can grow in poorer soils, applying a balanced fertilizer every few weeks during peak growth will encourage more blooming and healthier foliage.
Nasturtiums are relatively pest-resistant due to their peppery flavor; however, they may attract aphids or caterpillars occasionally. Monitor your plants regularly:
To encourage more blooms throughout the season, deadhead spent flowers regularly. Pruning back leggy growth will also help maintain a bushier appearance.
One of the most exciting aspects of growing nasturtiums is harvesting their edible flowers and leaves:
Flowers: Pick flowers when they are fully open; they can be used fresh in salads or as garnishes.
Leaves: Harvest leaves at any time during the season—they have a peppery taste similar to arugula.
Seeds: If you allow some flowers to go to seed, you can collect the immature seeds (often referred to as “poor man’s capers”) for culinary use once they reach maturity.
Even though nasturtiums are hardy plants, you may encounter some challenges while growing them:
Wilting Leaves: This can be due to underwatering or extreme heat; ensure consistent watering.
Yellowing Leaves: Overwatering or nutrient deficiencies could cause yellow leaves—check drainage and adjust fertilization if necessary.
Pest Infestations: As mentioned earlier, monitor for aphids or caterpillars and take prompt action if found.
Growing nasturtium in Maryland offers a rewarding experience filled with beauty and culinary versatility.
