About Nasturtium
- Tropaeolum Majus belongs to the family of Tropaeolaceae, a family of annual and perennial herbaceous flowering plants, and it is native to South Africa and Central America.
- The botanical name of Nasturtium is Tropaeolum Majus. Other common names of the plant include Watercress and Yellowcress.
- Nasturtium is a perfect addition to all gardens. Coming in both bushy and climbing varieties, they can find their spot in all types of gardens. These flowers attract good insects, like pollinators and hoverflies, and trap common garden pests like aphids.
- Nasturtium is a great garden companion for many different crops, including broccoli, cabbages, pumpkins, potatoes, or cucumbers. This small lovely flower will keep your crops healthy, fertile, and pest-free.
- When consumed raw or cooked, Nasturtium has plenty of health benefits, including improving the immune system, tackling sore throats, coughs, and colds, and fighting bacterial and fungal infections.
- There are many ways to use Nasturtium in the kitchen. You can use it to add a peppery and spicy taste to your salads, decorate your dishes with it, or you can make a tea out of its flowers and leaves.
- Tea made from Nasturtium is also an excellent remedy against unwanted bugs for your other garden plants. Simply spray it over your other plants, and these will keep various pests away. You can also use Nasturtium tea to stimulate hair growth since it helps increase the flow of nutrients to the scalp or as a remedy for acne when applied to oily skin.
- Nasturtiums are sun-loving plants. They need full to partial sun to grow happy and healthy. So, choose a sunny spot in your garden to grow them.
- In terms of soil preferences, Nasturtium prefers to grow in well-draining sandy soil with a slightly acidic to neutral pH. Ensuring good drainage to your Nasturtium plants is essential because they are susceptible to root rot when kept in soggy soil.
- This flower has relatively minimal watering needs. Water your Nasturtium once or twice a week but only when the top first inch of the soil is dry to prevent overwatering.
- Nasturtiums can be cold-hardy and make it through cold winters with a bit of help. If you add cardboard boxes overnight on cold winter nights, you can help these flowers survive temperatures as low as 20°F (-6,66°C).
- As mentioned above, Nasturtiums act like traps for most common garden pests. Aphids, spider mites, whiteflies, and leafhoppers are a few examples of pests that feed on these flowers by sucking their juices. However, Nasturtiums attract hoverflies and other beneficial bugs that dine on aphids and other pests. In cases of severe infestation, you can get rid of these pests with insecticidal soap.
Nasturtium Features: An Overview
- Nasturtium is an annual flower that can grow up to 6 to 12 inches (15-30 cm) or 1 to 3 feet (30-90 cm) high and 12 to 18 inches (30-45 cm) wide.
- These flowers can grow as either vinelike or compact bushy plants, featuring nearly round leaves and longspurs that grow 5-petal bright orange and yellow flowers at their ends.
- The blooming season of Nasturtiums starts in July and continues until late September.
- Although some parts of the Nasturtium flower are edible and packed with health benefits, the seeds are considered toxic and should not be consumed. What’s more, there are also some precautions regarding ingesting large amounts of Nasturtium. But the good news is this flower is generally considered safe for pets.
Growing Nasturtium
Growing and caring for Nasturtium isn’t difficult. These flowers are effortless to care for, and they are one of those garden plants that can thrive even when neglected. As long as you provide them with their basic growing needs, caring for Nasturtium won’t give you any headaches. Thanks to the fact that they are low-maintenance, these flowers can be grown by novice and experienced gardeners too.
First things first, it’s essential to remember that these plants love growing in full sun. In fact, they need at least 6-8 hours of full sun daily to bloom and thrive. If you can find a spot in your garden that is sunny most of the day and gets partial shade in the afternoon, your Nasturtiums will be really happy.
Fertilizing your Nasturtiums is another essential thing to do to help them grow and bloom, especially if your soil is extremely poor. We recommend fertilizing your plants throughout summer using liquid fertilizer. This will ensure plenty of blooms. Avoid fertilizers with too much nitrogen because this can encourage more foliage than flowers.
Pruning is also necessary to help your Nasturtiums stay happy and healthy and encourage more abundant blooms. Once the flowers are spent, make sure to deadhead the plants to encourage more blossoms. Keep in mind that vinelike plants are also particularly vulnerable to getting leggy and messy looking, so some pruning is necessary to keep the plant’s appearance neat. Simply trim back the longest vines by a few inches. This will stimulate new growth, both leaves and flowers, and more branching.

Generally, it is best to plant your Nasturtiums from March to May outside, in the spots where they are to flower. But, before you choose the places in your outdoor space, consider that:
The plant needs plenty of sunlight most of the day to thrive and bloom. So, pick the sunniest spots in your garden.
Nasturtium needs well-draining soil to prevent root rot. So, improve soil drainage by mixing it with coarse sand and crusher fines to allow excess water to pass through.
These flowers can survive a light frost, especially with a little help from you, but can easily get damaged by freezing temperatures. So, if you live in an area with very cold winters, it’s best to plant your Nasturtium in pots that you can move indoors during the cold season.
Remember to choose a spot that is sheltered from winds.
Watering Nasturtium
It is essential to know just how much water to give your Nasturtium plants.
This flower has minimal watering needs. They only require regular watering, about once or twice a week. But, remember to keep your Nasturtium well-hydrated during dry periods. However, you should also pay a lot of attention not to overwater your flower. In other words, adapt the frequency of watering to the season and humidity in your area.
To ensure that you don’t overwater your Nasturtium, we recommend using the “soak and dry” watering method. This means that you should only water your Nasturtiums when the top few inches of the soil are completely dry. This will prevent soggy soil.
Propagating Nasturtium
If you want more Nasturtium flowers in your outdoor space, propagation is relatively easy with this plant. Nasturtium can be propagated via cuttings and seed. Keep in mind that in mild areas that provide the ideal conditions, Nasturtiums will self-seed, coming back year after year.
To propagate your Nasturtium from cuttings:
- Take a 3 inch (7cm) section of stem and remove all its lower leaves.
- Place the cuttings in moist perlite or sand and wait for about two to three weeks for new roots to grow.
To propagate your Nasturtium from seeds:
- Collect seeds when ripe and save them to use them the following year when the weather and soil get warmer.
- Soak the seeds in water the night before planting to speed germination.
- Place the seeds 1 inch (2,5 cm) deep at about 3 inches (8 cm) apart and wait for new plants to grow.
In Conclusion
Having Nasturtiums in your garden is a delight. These flowers will fill your outdoor space with bright and vivid colours and attract all types of pollinators that will also benefit their garden companions. Nasturtiums will also protect your other plants from pests. Plus, these flowers have plenty of edible purposes and health benefits.
Growing and caring for Nasturtiums is incredibly easy. They have minimal growing needs and can survive even extended periods of neglect. So, by growing Nasturtiums in your garden, you get plenty of benefits for minimum work.

I will try planting nasturtiums in my garden this year. I have a heated greenhouse 6 x 12 foot and I have all raised beds. most of my beds are 24 inch x 12 foot, 2 foot in height. My question is as follows, can I plant nasturtiums in hanging baskets around the garden or do I have to plant them in the garden soil ?
