So, you've got yourself some Nasturtium Jewel Mix seeds, and you're itching to unleash a cascade of fiery hues in your garden. Excellent choice! These delightful, edible flowers are not just pretty faces; they're also incredibly easy to grow. This guide will walk you through everything you need to know, from the moment you crack open that seed packet to the blissful day you're savoring your first peppery nasturtium petal in a salad.
First things first: the fundamentals. Nasturtiums are surprisingly undemanding. They're like the low-maintenance friend who always looks fabulous. To kick things off, you'll need seeds (obviously!), well-draining soil, and a sunny spot. While they can tolerate partial shade, nasturtiums really shine when they get at least six hours of sunlight a day. Think of it as their daily dose of sunshine therapy.
The soil is crucial, but not overly fussy. Avoid rich, overly fertilized soil, as this will encourage lush foliage at the expense of flowers. Nasturtiums actually thrive in soil that's a little on the lean side. Consider mixing in some compost or well-rotted manure before planting, but don't go overboard. Good drainage is key to prevent root rot - nobody wants soggy nasturtium roots!
As for planting, you have two main options: direct sowing or starting seeds indoors. Direct sowing is the simplest method, especially if you live in a climate with a frost-free period. Just plant the seeds about half an inch deep and space them a few inches apart. If you want a head start, you can start seeds indoors 4-6 weeks before the last expected frost. This gives them a leg up on the growing season, but it's not strictly necessary.
Let's get our hands dirty! When direct sowing, choose your sunny spot and prepare the soil. Gently poke holes about half an inch deep and drop in a couple of seeds per hole (just in case some don't germinate). Cover lightly with soil, and water gently. Keep the soil moist but not waterlogged until the seedlings emerge. You should see sprouts within a week or two.
If you're starting seeds indoors, use seed starting mix in small pots or trays. Sow the seeds the same way as above. Keep the soil moist and provide plenty of light. Once the seedlings have a few sets of true leaves, you can transplant them outdoors after the danger of frost has passed. Harden them off gradually by exposing them to outdoor conditions for a few hours each day for about a week before planting them in their final location.
Watering nasturtiums is also straightforward. They prefer consistent moisture, especially during dry spells. Water at the base of the plants to avoid wetting the foliage, which can promote fungal diseases. Pinching off spent flowers will encourage more blooms, so don't be shy about deadheading. Nasturtiums are also relatively pest-free, but keep an eye out for aphids and other common garden critters.
Even the most seasoned gardener encounters challenges. Let's address some common nasturtium woes. Yellowing leaves can indicate overwatering or poor drainage. Ensure your plants are getting enough sunlight and that the soil isn't constantly soggy. A lack of flowers could mean the soil is too rich or that the plants aren't getting enough sun. Remember, they prefer lean soil!
Aphids can sometimes infest nasturtiums. If you spot them, a strong spray of water can often dislodge them. You can also use insecticidal soap or neem oil if the infestation is severe. Another common issue is leaf miners, which create winding trails on the leaves. Again, insecticidal soap can help, or you can simply remove the affected leaves.
Beyond basic care, consider these tips for a truly spectacular display. Nasturtiums are great companion plants for vegetables; they can help repel pests and attract beneficial insects. They also trail beautifully, so consider planting them in hanging baskets or along the edges of containers. Don't forget that both the flowers and leaves are edible, adding a peppery kick to salads, sandwiches, and even pesto. Enjoy the bounty!
The best time to plant Nasturtium Jewel Mix seeds depends on your climate. Generally, sow seeds outdoors after the danger of frost has passed in the spring. If you have a shorter growing season, you can start seeds indoors 4-6 weeks before the last expected frost. Nasturtiums also thrive in warmer climates and can sometimes be grown as perennials in mild regions.
Nasturtiums prefer consistent moisture, especially during dry periods. Water them regularly, especially during hot weather. Aim to water at the base of the plants, avoiding getting the foliage wet, which can help prevent fungal diseases. Check the soil moisture regularly and water when the top inch feels dry to the touch.
Yes, nasturtiums are very easy to grow! They are considered low-maintenance plants that are relatively pest-free and thrive in various conditions. They don't require heavy fertilization and can tolerate less-than-ideal soil conditions. Their ease of growth makes them ideal for beginner gardeners and those seeking a burst of color without a lot of fuss.
