How To Grow Nasturtium Flowers In Containers

Nasturtiums have a lot of vitamins and minerals in them. Many people regard them as weeds since they are overly zealous and spread quickly. You can keep them fresh for culinary use if you plant them in a container. By containing them in pots, you'll be able to protect your garden from their infamous spread. Let's look at how to grow nasturtium flowers in containers.


T. minus seeds, were among the loot brought back to Spain by the conquistadors in the 16th and 17th centuries.

The attractive, aromatic, and quick-growing plants were employed for culinary and aesthetic purposes. In the 1700s, a Dutch priest named Pater Beverning introduced the taller T. majus, which immediately became popular throughout Europe.

Nasturtiums were imported to North America in the early 1800s and immediately became popular due to their attractive blossoms, rapid growth, and climbing camouflaging behaviour, just as they had in Europe.

Is It Possible To Grow Nasturtiums In Pots?

Is It Possible To Grow Nasturtiums In Pots?

‘Nasturtiums grow wonderfully in pots,' Monty explains.

Bush nasturtiums are excellent for pots since they stay smaller, whereas trailing nasturtiums are better for window boxes or hanging baskets.

If you're planting them in containers, combine the compost with fine gravel or grit to aid drainage and reduce nutrient levels, as they prefer poor soil.

Sow one or two nasturtium seeds per pot to prevent them from outgrowing it.

If you're growing nasturtiums in pots, you can put them in a little shadier area to prevent them from overexposure and the drying effects of the sun.

Nasturtium Varieties

Before starting to grow nasturtium flowers in containers, you should need to know the best varieties of nasturtium.

Follow the steps that will help you grow nasturtium flowers in containers perfectly!

Time To Plant

Plant nasturtiums four to six weeks before the latest frost date to grow them in containers. Because they flower early in the spring, the plant will have plenty of time to flourish. When it's cold outside, or there's a lot of wind, bring the container inside. After the last frost has passed, move the pot to where the plant will get enough light.

You can grow them as annuals if you reside in a mild summer environment. Keep them out of the sun for as long as possible. They do, however, only grow in the absence of frost.

Pot Requirements

Pot Requirements

Nasturtiums should be grown in pots 10-12 inches in diameter. They can also be grown in window boxes because they are good runners.



This incredible plant thrives in poor soil. Plant them in loose, well-drained soil with plenty of organic materials. Planting should not be done in heavy, moist, clayey soil.

Before putting them in containers, you can use a balanced organic fertilizer.


Nasturtiums need direct sunshine to grow properly. However, keep them out of the hot sun in the afternoon. If you're growing them as houseplants, make sure they're near an east-facing window, so they get plenty of light.



When the soil becomes dry, water the nasturtiums. Scrape off the topsoil with your nails to see if this is true. It's usually adequate to water the container once a week, and water twice a week during the hot summer months. If the soil remains moist for an extended time, the nasturtium can grow mould.

Propagate Nasturtium From Seeds

Propagate Nasturtium From Seeds

Seeds are the most popular and straightforward technique to propagate nasturtiums. Seeds can be obtained from a nearby nursery. Nasturtiums come in various shapes and sizes, including bushy, trailing, and climbers.

Although all kinds can be grown in containers, trailing plants are the most suitable. You're set to go once you've planted a few seeds in the container. It's that simple! The nasturtium seeds will germinate on their own because it thrives on neglect. Germination is aided by soaking nasturtium seeds overnight before planting.

The seeds are difficult to get by. Once you've gotten your hands on this plant, save the seeds so you may replant them in the spring.

Propagate Nasturtium From Stem Cuttings

Spring is the optimum time to collect stem cuttings for propagation because the weather is mild.

Here's how to do it:

  • Snip a four- to six-inch stem section, cutting one to two inches below a leaf node (where the leaf joins the stem).
  • Remove the lower two-thirds of the stem's leaves.
  • If desired, dip the stem in the rooting compound up to the leaf node.
  • Fill small biodegradable pots with a mild potting soil mix, two to four inches in diameter.
  • Insert one or two cuttings per container and gently firm dirt around the stems.
  • Place the pots in a safe area that receives morning and afternoon sun. When new leaves develop in two to three weeks, roots have formed.
  • Transplant the plants into the garden in their biodegradable pots to avoid root damage.

Pruning & Maintenance

The grooming or deadheading of flowers regularly encourages the formation of new blossoms.

  • If plants get strung out or lanky, cut them back to half their original volume, and they will immediately develop new growth.
  • Give plants a modest trim in late spring or early summer to restore shape and encourage new flower production.
  • Provide climbing kinds with trellis or pea netting for support. To get the climbers started, you may need to point them in the appropriate direction.
  • When grown in containers, they need to be trimmed now and then to keep their shape and flower output up. Cut plants down by half if their vigour wanes in the summer heat. As soon as the evening temps calm down, they'll regenerate with fresh vigour.
  • Allow seed pods to develop on the vine before collecting seed for stock comprehensively. They will turn from green to a light tan tone.
  • Allow seeds to fall to the ground independently, then gather them afterwards. Remove any filth with a gentle brush.

Allow drying for another two to four weeks in a warm, dry location, spread out on a plate or tray. Before storing seeds, they must be scorched. When the seeds have dried and become brown, store them in glass jars or paper envelopes in a cold, dark place.

Remove any remaining debris after plants are felled by frost in cooler zones to avoid unfriendly bugs from overwintering.



Harvesting leaves and flowers are achievable at any time. Before the seeds have had an opportunity to grow and harden, the seedpods should be picked.

Snip off leaves, blooms, and seedpods using scissors to prevent injuring the plant.

If you let the seedpods mature, you may preserve the nasturtium's chickpea–size seeds and replant them in the spring. Allow the seeds to dry on the vine until they fall off. Collect them, brush off the soil, dry them, and keep them in a cold, dark place in a paper envelope.


When pickled, the immature green pods are excellent. They're also known as “poor man's capers,” They're a great alternative for the real thing.

To do so, collect the pods, gently wash them to eliminate dirt, and set them in a jar.

Pour enough white vinegar to cover the pods into a pot with a bay leaf and a teaspoon of salt for every cup of vinegar used.

Bring to a boil, remove from heat, and pour over the pods, ensuring they are well covered in the vinegar and salt solution.

Refrigerate after sealing the jar and allowing it to cool. They will be ready to use in two to three months.

Pests And Disease

Pests & Diseases Of Nasturtium Flowers

Although disease-free, there are a few pests and issues to be aware of.

Aphids are little black, green, or reddish sapsuckers that feed on flowers, leaves, and stems, spreading illness.

A powerful spray of water from a garden hose can kill aphids on stems, flowers' undersides, and leaves' undersides.

Cabbage loopers are green worms that devour the leaves of cabbage plants and put their eggs on them.

Pick them out by hand and throw them away.

Leafhoppers are minor, sap-sucking, disease-spreading bugs with solid back legs that bounce from leaf to leaf.

Use insecticidal soap to get rid of leafhopper infestations. Leafminers are tiny black or gray insects that dig into leaves to lay their eggs, leaving bleached, serpentine patterns on the leaves.

Remove and destroy diseased leaves and spray with neem oil to control adults. Flies can overwinter in the soil, keeping the beds clean and using fresh dirt next spring.

Slugs and snails chew leaves, leaving uneven notches or completely devouring them. Slugs and snails should be hand-picked and disposed of.

Stunting or witches' brooms — excessive leafy growth on the green, malformed flower petals – is caused by Aster yellows, which is caused by a microscopic organism known as phytoplasma. Leafhoppers spread this bacteria-like infection. Infected plants should be removed and destroyed as soon as possible. Control leafhopper populations and weeds, which may serve as hosts for the illness.

Clubroot is a fungal disease caused by Plasmodiophora brassicae, ubiquitous in acidic soil or areas where Brassica species have previously flourished.

The damaged roots are strongly clubbed or twisted, and the leaves can be stunted or wilt.

If you notice symptoms of this illness, remove and kill the plants. Acidic soils should be limed, and replanting in the same spot should be avoided.

A variety of bacterial diseases can infect the mosaic virus. It causes leaf spotting or mottling ranging from light to dark green and deformed or splotchy blooms. Aphids and leafhoppers are vectors for mosaic viruses. Infected plants should be removed and destroyed, and insect infestations should be treated as needed.

Wilt is a bacterial infection produced by Pseudomonas solanacearum, which dwells in plant waste and invades roots from the soil.

Plants turn yellow and wilt before dying, and damaged locations may develop black streaks or seeping slime.

Remove diseased plants and sanitize any instruments that have come into touch with them using a 10% bleach-to-water solution. Also, avoid watering from above because this bacteria can be spread by spilling water. Before winter arrives, make sure the plant beds are free of debris.

Uses For Ornamental Purposes

When climbing up arbours, fences, and trellises or pouring down from hanging baskets and window boxes, Tropaeolum types provide incredible vertical growth and fantastic colour.

Compact varieties make stunning spillers in pots or topple over the edges of low foundation walls and rock garden pockets, and they add flair to raised beds and borders.

Nasturtiums create a decorative and valuable scrambling ground cover for concealing stumps or unsightly locations, as well as a weed barrier to prevent encroachment of the garden or lawn, thanks to their fast-growing, abundant leaves.

The profuse foliage works well as a filler or seasonal screen in challenging situations, such as beneath decks or stairs, poor soil sites, and shady spots.

Nasturtiums are an excellent aphid trap crop when grown as a companion plant. Plant near the crops you want to protect as a trap, then hose off aphids as needed.

Many caterpillars, cucumber beetles, squash bugs, and whiteflies are deterred, whereas predatory insects such as ladybugs, lacewings, and parasitic wasps are attracted. The Tropaeolum genus can be grown alongside Brassicas, cucumbers, melons, radishes, and tomatoes.

Nasturtiums are always an excellent choice for children's gardens because of their numerous exceptional traits and rapid growth.
