So, you've decided to grace your garden with the peppery pizzazz of nasturtiums? Excellent choice! These vibrant bloomers aren't just pretty faces; they're edible, attract beneficial insects, and generally make your life easier. Unlike some prima donna plants, nasturtiums are surprisingly low-maintenance, making them a perfect project for both seasoned gardeners and enthusiastic beginners. Let's dive into how to get those seeds in the ground and watch the magic happen.
Nasturtiums are notoriously easygoing, but even they have their preferences. The first step to a bountiful crop is knowing when to sow those little seed nuggets. Forget waiting until the last frost has passed. You can sow directly outdoors once the danger of frost has vanished and the soil has warmed up a bit. This is typically in spring, but depends on your local climate. For earlier blooms, you can start seeds indoors a few weeks before the last frost, but honestly, direct sowing is simpler. You want to be in the game after all the harsh weather.
Next, the soil. Nasturtiums aren't fussy about soil type, but they do prefer slightly poor, well-draining soil. Rich soil will lead to lush foliage but fewer flowers. Think of it like feeding a teenager: too much fertilizer and you get all limbs and no brains. Amend heavy clay soil with compost or sand to improve drainage. Choose a spot that gets at least 6 hours of sunlight per day. Nasturtiums will tolerate partial shade, but they'll really shine in full sun. Dig those seeds right into the ground!
Before planting, consider the variety. There are many nasturtium varieties, from trailing vines to compact bushes. Think about where you want them to grow. Will they spill over a pot, climb a trellis, or simply fill a bed? Varieties like 'Alaska' offer colorful foliage, while others, like 'Jewel', provide a vibrant mix of flower colors. Once you have your seeds, sow them about 1/2 to 1 inch deep and space them according to the seed packet instructions. Water them gently after planting and then await the show!
Now that you have your seeds ready, it's time to get your hands dirty. Direct sowing is the easiest method. Simply create small holes in the soil, drop in a seed or two per hole (depending on the seed packet instructions), cover lightly with soil, and gently water. If you're starting seeds indoors, use small pots or seed trays filled with seed-starting mix. Plant the seeds at the same depth as you would outdoors. Keep the soil moist but not waterlogged. You can also start them in peat pots, and then plant them directly to avoid transplant shock. Consider setting up a DIY system of support, like a tomato cage or a simple string trellis.
Once your seedlings emerge, which should take about 7-10 days, you can thin them, removing any weaker plants. The goal is to space the remaining plants appropriately so that they have room to grow. Nasturtiums don't usually need much in the way of feeding. A little bit of compost added to the soil at planting is usually sufficient. Over-fertilizing can result in a lot of leaves and not many flowers. If your plants seem to be struggling, a balanced liquid fertilizer can give them a boost, but go easy.
Watering is crucial, especially during dry spells. Nasturtiums prefer consistent moisture, so water regularly, especially in hot weather. Allow the soil to dry out slightly between waterings to prevent root rot. Deadheading spent flowers will encourage more blooms. Simply snip off the faded flowers to keep your plants looking tidy and encourage more flower production. Pest control is generally minimal. Nasturtiums can attract aphids, but a strong jet of water from the hose can usually dislodge them.
Even the most enthusiastic gardener faces the occasional hiccup. Let's tackle some common nasturtium challenges. Yellowing leaves can indicate overwatering or poor drainage. Adjust your watering schedule accordingly and ensure your soil is well-draining. Leggy growth often results from insufficient sunlight. Move your plants to a sunnier location. Few flowers? This is often a sign of too much fertilizer or overly rich soil. Avoid using fertilizers to encourage flowering.
Harvesting nasturtiums is one of the best parts! The flowers and leaves are edible, with a peppery taste reminiscent of watercress. Harvest the flowers when they are fully open, and the leaves when they are young and tender. You can use them in salads, as a garnish, or to add a zesty flavor to sandwiches. The seeds can also be pickled and used as a caper substitute, adding a fun twist to your culinary creations. Use the flowers right away for the best flavor.
Embrace the beauty and simplicity of planting nasturtium seeds. They're a delightful addition to any garden. With minimal effort, you can enjoy a vibrant display of color and flavor all season long. So get those seeds in the ground and prepare to be amazed by the cheerful blooms and delicious possibilities of your new nasturtium patch!
The best time to plant nasturtium seeds is directly outdoors after the danger of frost has passed and the soil has warmed up, typically in spring. You can also start them indoors a few weeks before the last expected frost for earlier blooms, but direct sowing is generally easier for these low-maintenance plants.
Nasturtiums thrive in full sun, which means at least 6 hours of direct sunlight per day. They will tolerate partial shade, but you'll get the best blooms in a sunny location. Ensure they get plenty of light for those vibrant flowers.
Yes, nasturtiums are remarkably easy to grow, making them ideal for both beginners and experienced gardeners. They are not fussy about soil, prefer minimal fertilization, and are relatively pest-resistant. They are also very adaptable and produce a bountiful crop of flowers and foliage.
