How to Plant, Grow, and Care for Nasturtium
Nasturtium is an easy-to-grow annual whose leaves and flowers are edible. Here’s how to grow your own nasturtiums!
These plants, with their bright greenery and vibrant flowers, are good for containers or as ground cover. Their pretty fragrance also makes them a good choice for cut flowers. Nasturtiums are perfect to grow with children because they grow so easily and rapidly.
Planting
- You can start the seeds indoors 4 to 6 weeks before the last spring frost. See your local frost dates.
- Plant nasturtium seeds in early spring in moist, well-drained soil in full sun. They can grow in partial shade, but they will not bloom as well.
- Nasturtiums prefer poorer soils and they do not need fertilizers (unless your soil is extremely poor). Fertile soil will produce fewer blooms and more foliage.
- Plant the seeds about half an inch deep and 10 to 12 inches apart. Plants should appear in 7 to 10 days.
Care
- Water regularly throughout the growing season, but be careful not to over-water your plants.
- Cutting off the faded/dead flowers will prolong blooming.
- If you’re growing nasturtiums in containers, they may need to be trimmed back occasionally over the growing season.
Pests/Diseases
- Flea beetles
- Caterpillars
- Aphids
- Slugs
- Whiteflies
- Viruses
Harvest/Storage
- Save the nasturtium’s chick-pea-size seeds and replant them in the spring! Let the seeds dry out on the vine; they’ll fall off. Collect them, brush off the soil, dry them, and store them in a paper envelope in a cool and dark place.
Recommended Varieties
- ‘Salmon Baby’, to add a pretty salmon-pink color to your garden.
- ‘Variegatus’, which is a trailing type with red or orange flowers.
- ‘Peach Melba’, which is derived from nasturtiums and has creamy yellow flowers with orange-red centers.
Wit & Wisdom
- Nasturtium flowers are said to symbolize patriotism. Find out more flower meanings here.
- Nasturtium flowers are one of several common garden flowers that are edible!

Can u cut the big leaves off nasturtiums
If I did this would I see more of the flowers
nasturtium leaves
The leaves are the way the plant gets its food to grow so don’t cut the leaves too early. However, if your nasturtium is getting out of control, then it’s best to trim back the tips and undersides of nasturtiums every few days even if it means trimming off flowers that have yet to bloom. This is hard to do but will keep the plant more compact and healthier. If you have too many leaves at expense of blooms, it may be because you are using fertilizer. It’s better to not fertilize them to have plants with good blooms that last longer rather than a crazy, full knockout plant that will only last a few weeks.
Nasturtiums
Aren't nasturtiums vines? My plants are not climbing on the trellis in the pot. Not sure why.

It depends upon the type of nasturtiums you are growing. The dwarf varieties grow low to the ground and stay in more of a bunched fashion, growing upwards (Jewel/Alaska varieties) . The trailing type (Tropaeolum majus (Empress/Moonlight/Amazon Jewell varieties)) will either cascade or can be trained to crawl upward onto a fence, border or stand. I hope this helps in some way?
Big beautiful blooming ‘bush’ of nasturtiums
Turned yellow and died in a small garden bed....after Spring. No California sun.
Why? Should I remove from garden bed?
Nasturtiums
If they’ve died completely, they can be removed from the bed. As for what caused them to perish, it’s hard to say without knowing more… What have the weather conditions been like? Dry? Wet? Are other plants growing well in the same soil?

planting nasturtium in zone 8
My nasturtiums are not growing. Small leaves, no flowers. They are in sandy soil.
Nasturtium not flowering
Can i use mono potassium phosphate to force my nasturtiums to force for blooming . As by mistake I have put fertiliser to nasturtiums
mono potassium phosphate
This is an eco-friendly fertilizer and your plants should benefit from it, if applied as directed on the package.
Nasturtium
Nasturtium grows fast in my small pot. Sunny climate in India. Temperature is rising now. Average 12-14 degrees C. Put water in afternoon.( 4-5 p.m).
nasturtiums rising
Sounds like ideal conditions are in your favor!
Nasturtium
I have seen germination of Nasturtium seeds . It will grow in my flower pot. It's December. I cherish to see saplings now. Hope to give flowers in due time.
Nasturtiums
I buy packets of nasturtium seed showing a variety of colours but only ever get orange and yellow flowers. What is the cause of this?
Nasturtium leaves
Our nasturtiums bloom profusely, but the leaves are large and taller than the flowers. The leaves cover up almost all of the flowers. We would have to cut off the leaves to see the blooms. Is this because our soil is too rich or has too much nitrogen? Thanks in advance !

nasturtiums flowers lost in leaves
Shade reduces the number of blossoms and increases leaf size (and reach). It may also be due to too-moist soil.
Nasturtiums in the Fall
It is the end of September, do I need to pull my plants out or do I just leave them alone for next year? Will they die back over the winter?
nasturtiums in fall
Nasturtiums are annuals. They will die with the first frost—and not comeback.

eating Nasturtium
please tell me how are these Nasturtium able to be eating by humans ? how would one prepare them?
Eating nasturtium
They have a slight peppery taste. I wash and use fresh to add colour and flavour to salads and smoothies. I have also used in stir fries
Eating nasturtium
Take a stick of butter and let it soften to room temperature. Chop orange or red nasturtium flowers into small pieces and mix into the butter. Reform into any shape and refrigerate. The nasturtium butter will have a peppery flavor and will be a colorful addition to the lunch or dinner table. Use on toast or in any dish where pepper would compliment the taste and color would enhance the presentation. Also, simply chop nasturtium leaves and add into any salad. Like the flowers, the leaves add a peppery flavor. Add flowers and/or leaves in meat,vegetable, fruit or cheese dishes where pepper and color would be appreciated. Add just before serving to look brighter and taste fresher.
Can nasturtiums be planted in a hanging basket
Hi,
I'm from Islamabad...Pakistan. Our spring is almost here with no danger of any more frost.
I had these nasturtium seedlings....alĺ in one small pot...which were quite leggy and had yellow leaves. I planted these in a hanging basket(wire basket with coco liner) along with petunias and verbebas. Nasturtiums are inserted through the side slits. But now Im worried if they are going to catch back with petunias, which are quite healthy, or not...as the nasturtiums look very weak n shabby. The soil is a mix of peatmoss n perlite.
Shall I remove the nasturtiums or they'll do fine in the basket? Please advise.
Thanks
Hanging basket - Nasturtiums
The peatmoss and perlite soil may be too nutrient rich. These flowers prefer poor soil. The rich potting soils used for hanging plants may not agree with it.
Compost
Hi
Can I compost Nasturtium vines? I am worried that seeds may be a problem and not break down as I do not wish Nasturtiums to spread to other areas where I will use this as mulch.
Cheers
Composting Nasturtiums
Hi Melodee,
Yes, you can compost nasturtium vines, flowers, and seeds. There is only a small chance that any seeds would spread through the mulch. Nasturtiums don’t spread quickly or aggressively.
If I plant Nast by the garden...
If I plant Nasturtium near the garden to keep the bugs away- it will get water as the garden does. How far do I keep them from the garden to be useful but thrive?
Nasturtium
Nasturtium do like to have regular waterings; they just don’t like to sit in water for extended periods. If you water tham as you water your veggie garden, they should do fine. Plant them far enough away from the veggies so that the two plants won’t physically touch when fully grown. Approximately two yards away would be great. The idea is to use the nasturtiums as bait for the bad bugs, so we want to draw them away from the garden and keep them away.
Transplanted with good soil by mistake
Hi I transplanted some wild nasturtium into pots with good fertilizer without knowing they thrive in poorer soil. I cut them all the way back and they have grown and thrived besides the lack of flowers. They were nonexistent. Is there a way to simulate poorer soil or somehow get them to produce more flowers? Thank you.
