Nasturtium – Isn’t really a single plant, but more like a genus of over 80 flowering plants, these encompass both perennial and annual blooming species. From Central and South America, this herbaceous flower comes in more of the most vivid and saturated colors of any flower. Harvest Planted: Start planting in the spring after the threat of frost. They grow fast and are easy to maintain. Basically, they thrive on abuse!TIP: Nasturtium flowers, which are generally on the hot side in the color spectrum. The cute, rounded leaves resemble tiny lotus leaves.
Nasturtium varieties for everyone! For hedges and edges, other styles of plants, for walls of plants and containers and climbers for impressive height. The leaves and flowers are green and edible with a peppery flavor. You will, therefore, see this plant in vegetable gardens, often planted in, say, the middle of a row of broccoli, cabbage, and cauliflower, where it will help repel pests.
Types of Nasturtium
Nasturtiums are full plants with rounded green leaves and colorful flowers peeking out here and there. This plant’s flowers are funnel-shaped and come in various shades of yellow, orange, pink or red. Some types have soft butter yellow and cream colors, with others have variegated leaves.These are just a few of the nasturtium varieties that people most use, from the dozens that are available:
- Alaska Series’ – A gingery heirloom variety brightens variegated foliage with blooms that sport varied colors, held high above the leaves. The compact plant grows well in poor soil and reaches a maximum spread of 8 to 10 inches.
- The ‘Jewel’ Series’ rampant impatiens grows to 16 inches tall and provides yellow, mahogany, red, orange, and rose flowers. It is also a fabulous bloomer but the blooms mostly are hidden beneath the foliage.
- The two-toned flowers of ‘Peach Melba’ are yellow with maroon spots near the center and taste like watercress. This compact species is container-friendly, boasting a full mature size of 10 to 12 inches both tall and wide.
- Height: trailing type that can grow 10 feet and up when allowed to climb, best near fences and/or trellises. This uncommon species has yellow flowers that are set apart from the commonly known types as they are shaped like canary wings.
Nasturtium Care
Nasturtiums are also either sown from seed as annuals, or purchased as starts at garden centers, where you may find them on sale next to other vegetable companions. The seeds germinate with extreme speed and the plant starts budding fairly rapidly. If started from seeds, nasturtiums are pretty self-sufficient. Wanting the exact same water the neighboring plants would need. You can deadhead (remove spent blooms) but it is not necessary, however, taking a few to pull open for use in a summer salad or laying on top of a summer dessert is always acceptable.
As edging, nasturtiums are beautfiul spilling over walls and into the pavers. They do equally well in containers. The bushy, carpeting nasturtiums will occupy bloom gaps in a sunny perennial bed and make good companions for day lilies or roses.
Light
For best growth and blooming, plant your nasturtiums in a sunny spot that gets 6 to 8 hours of direct sunlight everyday. While this plant will grow in some shade (three to six hours of sun) it may not bloom as much. Can be grown in partial shade in warmer climates because in high temperatures the leaves turn brown.
Soil
Also, to my surprise, nasturtium flowers perform beautifully in less fertile soil as long as it drains well. If the soil is too rich, you will have a garden filled with lush foliage but few blooms. Varieties Varieties of Yarrow Common yarrow grows well in a wide range of soil pH from 6 to 8 and is drought-tolerant once established although a moderate amount of moisture is appreciated.
Water
Normally, Nasturtiums can be irrigated weekly, but when these are developed in a green- house or in a sparkly vegetable piece, these may be irrigated even all other day. In high water demand conditions, it becomes dry quickly, and the surrounding plants tend to take its water. Nasturtiums are drought tolerant but you will lose your blooms and the foliage will start to look spindly in semi-dry conditions.
Temperature and Humidity
Traditional perennial plants nasturtium grow in USDA plant tough zones 9 with 11. Yet in many North American regions, it is an annual and must be replanted each growing season. Spider plants like day temperatures in the 70s F and can take a light frost, but not a freeze. Plus, this plant enjoys an average human and is not too fussy (30% to 50% humidity level). That said, nasturtiums can have some trouble with either very dry or very humid conditions.
Fertilizer
If it is a vegetable that you are going to eat, it is generally not recommended using synthetic fertilizers. Most typically, organic gardeners will have little need to amend the soil before planting (except under very poor conditions or if the surrounding vegetables need soil to be mounded up over their roots); but few of us are so discriminating. Keep in mind that overly rich soil characteristics may encourage nasturtiums to produce primarily foliage with few flowers. Thus, a balance is required.
When to Plant Nasturtium Seeds
VanZile writes: It’s sort of like a nasty trick of nature that those disc-shaped, slightly angled leaves with smooth margins and cone-shaped flowers of nasturtiums come from brain-shaped seeds. Nasturtium seeds germinate quickly, and it isn’t necessary to start them indoors weeks in advance. If you are like me, then you might just want to plant them directly into the ground whenever you start your garden in the spring. Even in the middle of (high) Summer, you can achieve this. Sprouting can happen in 48 hours. Nasturtium is, on the whole, a tender plant (it even likes to stay toasty in zones 10 and 11). Enter seeds into the ground two or three weeks after the last frost vanZile gets a 4.
Where to Plant Nasturtium Seeds
Nasturtiums do best in full sun all day, so the ideal place to start planting is in an area that receives plenty of light. And if it falls in that negative space at the top of your garden, even better: Nasturtium will fight garden pests like deers and aphids for you (it has a spicy flavor and they hate that), so they need to be played defense as well.
When choosing a nasturtium variety for your garden, take into account the size of established plants and the general layout of your property. Wingenfeld and VanZile say, for instance, trailing types need a lot of room to wander, in contrast to Jewel species (a smaller version). In the end, nasturtiums are available in numerous variegated kinds therefore colors. So, you can easily find out and even you can team them with other plants which will also not need much watering or fertilization. However, a climbing/ trailing nasturtium in a regular bed will need support.
How to Grow Nasturtium in Pots or Containers
Because being friendly is the nature of nasturtium. It is very easy to grow in almost any pot or planter (if you follow the rules of the game – see above). Planting seeds in containers works much the same way. Place each of them half an inch under and give them a good dose of moisture when done.
Pruning
Trailing nasturtiums can be leggy, and they typically need a good trim no later than mid-summer, then again late in the summer, to promote more growth and blooms. For trailing types, snip back the longest stems by 6 to 12 inches and remove any browning leaves and flowers by pinching them off at the base. Bushy varieties generally do not require a cutting of stems, unless you want to pinch off any spent flowers or dry leaves for the sake of the plant looking good in its entirety.
Common Pests and Diseases
Nasturtiums suffer from aphid attack, so they discourage them from other aphid-prone vegetables. Aphids – The foliage on your plant can begin to look wrinkled on the plant or just plain unhealthy. Treatments for thrips on plants Reduce the population with a forceful blast of water from your garden hose. Alternatively you could go the homemade vinegar that has been diluted version, or then again the home made lavender or peppermint essential oil spray that is children and pet safe. Even better yet, pair the catnip with nasturtiums to repel the pests entirely.
It can also suffer from bacterial leaf spots. This is quite noticeable as small brown or black spots will appear on the leaves. You can also minimize the problem by planting far enough apart to allow plenty of airflow between plants and by watering with trickle irrigation as opposed to sprinklers since the disease spreads through splashing water.
Common Problems With Nasturtium
There are actually certain kinds of nasturtium that actually prevent flowers because of the shape of the plant. If growing nasturtium horizontally closer to the ground rather than as a vining or trailing variety, select a variety with flowers held above the foliage so the sun can reach the blossoms.
If the roots of the nasturtium are waterlogged, then it is afflicted with root rot. It prefers almost sandy soil, so make sure there is excellent drainage in the location you choose.
