Nasturtiums, those delightful trailing beauties, are not just a treat for the
eyes but also a feast for the palate! With their vibrant blooms and peppery
leaves, they add a splash of color and flavor to any garden. Whether you're a
seasoned gardener or just starting out, growing nasturtiums (Tropaeolum spp.)
is a breeze. Let's dive into this growing guide and unlock the secrets to
cultivating these cheerful plants.
Getting to Know Nasturtiums
Before we get our hands dirty, let's acquaint ourselves with
our star plant. Nasturtiums belong to the genus Tropaeolum and come in various
species and cultivars. They're known for their round, shield-shaped leaves and
brilliantly colored flowers that range from fiery oranges and yellows to soft
creams and reds. Edible from leaf to petal, nasturtiums offer both ornamental
and culinary appeal.
Planting Nasturtiums
Nasturtiums are champions of versatility and adaptability,
thriving in various conditions. Here's how to get started:
Soil:
Nasturtiums aren't too picky about soil quality, but they do
prefer well-drained, slightly fertile soil. However, they can tolerate poorer
soils as well, making them excellent candidates for less-than-ideal garden
spots.
Sunlight:
These sun-worshippers thrive in full sun but can tolerate
partial shade. Aim for at least 6 hours of sunlight daily for optimal growth
and blooming.
Planting:
When the threat of frost has passed and the soil has warmed
up, sow nasturtium seeds directly into the ground. Space seeds about 10 to 12
inches apart and cover them lightly with soil. You can also start seeds indoors
a few weeks before the last frost date and transplant them outside once the
weather warms up.
Care and Maintenance
Once your nasturtiums are settled in, they require minimal
care but reward you with abundant blooms. Here are some tips to keep them
thriving:
Watering:
Nasturtiums are drought-tolerant once established but
appreciate regular watering, especially during dry spells. Water them deeply
when the soil feels dry to the touch.
Fertilizing:
Avoid overly rich soil or excessive fertilization, as this
can result in lush foliage but fewer flowers. A balanced, all-purpose
fertilizer applied sparingly in early spring is usually sufficient.
Pruning:
While not strictly necessary, deadheading spent blooms can
encourage continuous flowering and keep the plants looking tidy. Plus, you can
munch on the peppery petals as you go!
Pests and Problems
Nasturtiums are relatively pest and disease-resistant, but
they can occasionally encounter some issues:
Aphids:
These tiny pests sometimes take a liking to nasturtiums.
Blast them off with a strong jet of water or introduce beneficial insects like
ladybugs to keep them in check.
Powdery Mildew:
In humid conditions, nasturtiums can fall prey to powdery
mildew. Improve air circulation around the plants and avoid overhead watering
to prevent this fungal disease.
Harvesting and Enjoying
The best part of growing nasturtiums? The harvest, of
course! Here's how to make the most of your bounty:
Leaves:
Add a peppery punch to salads, sandwiches, and stir-fries by
tossing in nasturtium leaves. They make a zesty addition to any dish.
Flowers:
Nasturtium flowers aren't just for show—they're a culinary
delight! Use them to garnish salads, desserts, and appetizers for a pop of
color and flavor.
Seeds:
Did you know nasturtium seeds are edible too? Pick them when
they're still green and tender, then pickle them for a unique and tasty treat.
In Summary
Nasturtiums are the perfect addition to any garden, offering
beauty, flavor, and versatility in one vibrant package. Whether cascading from
a hanging basket or spilling over a garden bed, these cheerful plants are sure
to brighten up your outdoor space. So go ahead, sow some seeds, and let
nature's fireworks begin!
