We’ve been asked a lot of questions throughout the years regarding our plants. Here are some responses to some often asked questions about petunia distribution.
Do spreading petunias need deadheading?
Generally speaking, no! Petunias for spreading are relatively low maintenance and don’t require deadheading. Throughout the summer, cutting back your Wave petunias can improve plant health and encourage new growth.
Do they come back every year?
No, Wave petunias will only grow for one growing season since, at least for the majority of the United States, they are annuals. Nevertheless, these plants can produce gorgeous blooms all summer long and will develop to an astounding size.
How long do they last?
Wave petunias typically bloom well into the fall. This depends on whether they contracted a sickness, received medical attention during the summer heat, and how soon it starts to get cold where you live.
How are Wave petunias prepared for winter?
Before the first fall frost, trim the petunias back to about 2 inches (5 cm) above the soil and place them in pots. Make sure they don’t have any pest infestations by thoroughly inspecting them. Before bringing plants inside, treat them if you notice any insects.
Put the plants somewhere cool but above freezing and give them a good watering. Find a place in your basement or garage where they won’t be in the way. Every three to four weeks, inspect petunias that are overwintering. Give them just enough water to hydrate the soil if it has become dry. If not, don’t touch them until the spring when you can replant them outside.
What distinguishes petunias from Wave petunias?
Wave petunias bloom extremely frequently and have a distinctive trailing growth habit. They are excellent summer performers and drape over the sides of containers and raised beds. A typical petunia grows erect or in a bush. While it might spread a little, it won’t fall as dramatically as a Wave petunia. An older hybrid than Waves, Cascade petunias are named after the Cascade mountain range rather than after how they grow. A shrub type petunia is called a cascade petunia.
Which petunias grow year-round?
One of the most popular summer bedding plants in our region is the petunia, which blooms from mid-summer until the first hard frosts of autumn. Their profusion of flowers fills gardens with wonderful color.
The trailing kinds liven up hanging baskets and flow down the edges of containers, while the compact, bushy varieties are ideal for planting in beds and borders.
Petunia flowers come in a vast array of colors, single and double blooms, smooth or ruffled petals, solid single, striped, veined, or picotee-edged colors, and even fragrance. The issue of ancient petunia types turning to mush in a wet summer has also been eradicated by recent breeding.
Petunias are perennial, despite the fact that the majority of bedding kinds are produced from seed annually as annuals. The perennial trailing varieties, like Surfinias, are cultivated from cuttings or young plants.
Cultivation
Although they will tolerate a little moderate shade during the hot, sunny summers, petunias like to be cultivated in full sun. They thrive on soil that is rich in nutrients, moist but well-drained. To keep moisture in sandy soils that drain very well, add lots of organic matter to the soil, such as garden compost, well-rotted manure, or other soil-improving materials.
Petunia varieties
Grandifloras, which have larger flowers, or multifloras, which have smaller flowers and are more resilient to rain, are the two varieties used as bedding.
The Surfinia, Wave, Tumbelina, Supertunia, and Cascadia series of petunias spread or trail.
Sowing petunias
Petunias can be grown from seeds inside with warmth in cell trays, seed trays, or tiny pots at a temperature of 18 to 24C as an annual or bedding plant (65-75F).
When plants are big enough to handle, prick them out into cell trays or tiny pots and let them continue to grow at a temperature of 50 to 65 degrees Fahrenheit (10 to 15 degrees Celsius) in good light.
Before planting the seedlings outdoors once all danger of frost has passed, gradually acclimate them to outdoor circumstances for 7 to 10 days.
Young petunia seedlings are available from garden centers and mail-order suppliers in the late winter/early spring if you don’t have the resources to grow them from seed.
Planting petunias
Make a good-sized planting hole that can readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.
Place the rootball in the planting hole, adjusting the planting depth (except for hardy fuchsias) until the top of the roots is level with the soil surface and the rootball is planted at the same depth as it was growing. Fill the planting hole with the excavated soil after adding more organic matter to it. Put some granular general feed on the soil and thoroughly wet it in. The soil can be kept moist and weeds can be controlled by adding a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or something similar over the soil. If you have a warm greenhouse, you can plant baskets and containers in the spring, let the plants mature, and then move them outside in late May or early June. You’ll have flowers earlier in the summer if you do this.
How to care for petunias
When there are protracted dry spells in the summer, water the soil frequently to keep it moist. Plants in containers will require routine, possibly daily watering with the intention of maintaining evenly moist compost. But be careful not to overwater, as this may make the plants leggy and produce few blossoms.
To ensure a steady supply of blossoms throughout the summer, feed your plants with a liquid plant food on a regular basis. Up to the first autumnal frosts, a high potash liquid plant feeding will promote more, better blooms.
The show will last longer if faded blooms and any sprouting seed pods are removed. Cut back straggly plants severely before feeding them with a liquid plant food to encourage fresh new growth and an abundance of blossoms.
Fall is the greatest time to dig up and compost bedding petunias that have been harmed by frost.
Overwintering petunias
Trailing perennial kinds can be pruned back severely in the fall, cleaned up by removing any dead or broken growth, and then gently lifted. They should be overwintered in a bright, frost-free location, preferably a greenhouse or cool conservatory, in pots just large enough to hold the rootball and with some fresh potting compost around the sides.
Propagating perennial petunias
Cuttings taken in March or April from plants that overwintered or in August or early September from perennial, trailing kinds can be used to create new plants.
Choose sturdy, healthy young stems that aren’t blossoming. If you can’t find sufficient growth, cut back hard one or two stems at the back of the plants to encourage vigorous regeneration. collect clippings 7.5–10 cm (3–4 in) long and positioned immediately below the node or junction of a leaf. In pots of gritted cuttings compost, place five or six cuttings at the base of the lowest leaves after removing the leaves from the lower two-thirds of the stem. Put the pots in a propagator or a plastic bag and set them somewhere with good light—but not in the sun—to root.
In two to three weeks, the cuttings should have taken, at which point they can be potted up separately and continued to grow.

To answer the first portion of your question, petunias can live for two or three years, but they typically behave like annuals because they can’t withstand the harsh winter weather. See more below on that.
It’s challenging to accurately assign a timeline to each particular blossom in the second part. Despite the fact that they don’t have a long lifespan, the plant produces so many of them that you might not even notice.
Can I store my petunias for the following season?
There are numerous reasons to appreciate petunias, but one that many gardeners overlook is the fact that you can really keep them from one year to the next, allowing them to bloom and prosper once more.
Petunias reappear the next year, right?
Do petunias reappear each year? Although petunias are perennials, they are frequently treated as annuals. In warm, all-year-round areas, they frequently endure and even blossom during the winter.
Wave petunias: Should I deadhead them?
Wave Deadheading Wave plants naturally do not need deadheading because of their abundant flowering, but doing it sometimes will increase flower production even more. Remove the blossom and the tiny stem holding it to the plant when it starts to fade.
Petunias from the Wave will they self-seed?
Petunias are a member of the Solanaceae family, which also contains well-known plants like Nicotiana, tomatoes, and peppers. Petunias are fragile annuals that require a lot of sunlight and sufficient moisture to thrive. In the ideal environment, they bloom all summer long and well into the fall. If left to their own ways, they might reproduce via seed, but the flowers won’t have the same hue as the parent plants’.
Can I grow Wave petunias outside?
The wave petunia combines the petunia’s behavior with that of a trailing vine plant. The flowers are distinctive to the original petunia and come in a variety of shades, including white, pink, red, purple, and yellow. These bloom continuously throughout the growing season and don’t need to be picked like a typical petunia.
There are various forms of wave petunias, including trailing, mounding, and spreading types. They grow well when planted directly in the ground and are suitable for hanging baskets and pots. The types that trail will spread out by 2 to 3 feet. Plan accordingly as your application grows.
Full sun is preferred for growing wave petunias. Although they can handle some sun, they struggle in the shadow. As long as you give them enough water and fertilizer, heat won’t be an issue. You can use your fingertips to feel the soil. If it is dry, it need treatment.
Spread Wave petunias?
The spreading growth behavior of wave petunia plants allows them to cover flower beds with blooms that appear all along their up to 4-foot stems (1 m.). Because they are so adaptable, wave petunia plants can be used to complement practically any area of your landscaping layout.
These plants can be used to support a 3 foot (91 cm) fence to create a dense hedge covered with blooms, or they can be used to cover a porch ceiling with enormous globes of color by planting vivid wave petunias around the base of a coir basket.
Wave petunias can be planted in substantial planters next to your front door and allowed to cascade to the ground; alternatively, you can plant a double row of them from the street to your porch to make a walkway lined with flowers.

With more options now available at nearby nurseries, wave petunias, a favorite of gardeners everywhere, are still creating an impact in the garden. Because these low-growing “spreaders” are extremely low-maintenance and can tolerate extremes of heat and cold, rain and humidity, millions of these super performers, introduced by Ball Seed Company, are planted by gardeners and experts alike. In Texas’ milder regions, flowers can bloom profusely long into the fall and perhaps even through the entire winter.
These types no longer have many of the issues that were present in older petunia strains, which were occasionally too big, too ruffled, too sensitive, and too susceptible to disease to be useful in all but the most favored settings.
Wave types don’t require pinching back or deadheading like traditional petunias because they can take care of themselves. Simply feed them well with an all-purpose plant meal once every few weeks, water them, and observe them flourish.
The Ball Company claims that the Wave petunia family is currently offered in five distinct series and a wide range of colors. The Wave, Tidal Wave, Easy Wave, Double Wave, and Shock Wave series are now available in noticeable Pink Pots at your neighborhood home improvement or garden center.
Here are some ideas for using Wave petunias to create a style statement without putting in a lot of work:
- Make a Promenade. Make a warm, vibrant welcome by filling a container with any of the fantastic colors of Shock Wave petunias, like the vivid “Rose” type. Shock Wave petunias pack the area with a ton of tiny blooms, making them the ideal choice for containers and small-space gardens.
- Outdoor chandeliers.
A basket of Easy Wave petunias in a single color set on a conventional pedestal would provide a classy focal point. Easy Wave petunias make the ideal chandelier of petals by piling up and outward. To create a distinct, upscale space, place the pedestal inside the landscape along a walk or place two at any entry.
- Rise to Heaven on Stairs. Pick any color you like. Create a heavenly corridor by lining a path with Wave, Tidal Wave, or Easy Wave petunias; the enormous blooms soon fill in. One strong color might be used, or the colors can be graduated from top to bottom. Space the young plants closer together for a more professional appearance so they can weave around one another and produce a dense mass of color.
- Pots in Spots With pots of Wave petunias, you may provide immediate interest and ongoing color to the garden or perennial border. A trendy design that adds punch and highlights any area of your yard is created by an overflowing pot of a single color, especially when perennials are not in bloom.
- Goodness, what beautiful flower balls. By making holes in the edges of a cocoa-fiber basket and stuffing them with baby Double Wave petunia plants, you can create a huge globe of color. On top and around the sides of the basket, space the plants a few inches apart. From the center, the petunias will expand and swell to form a big, luscious ball of color.
- pots of power You get a powerful effect from a concentration of only one plant in just one color. The porch’s extra-large pot is undoubtedly an attractive draw. You can increase drainage, make your container simpler to move, and use less potting mix by filling the bottom of the container with lightweight materials. Styrofoam packing peanuts, plastic water bottles, and plastic nursery pots can all be reused in this manner to fill empty space.
- Front Appeal Want to improve the curb appeal of your garden without having to completely redo it or break the bank? Petunias from the Tidal Wave collection, especially Tidal Wave Hot Pink, can save the day! These spreading petunias can be planted in a mass or arranged in stripes, borders, or clusters. This easy-to-care-for, rapidly expanding crowd-pleaser will make a striking impression.
- Blend It Up. The Shock Wave and Easy Wave series are offered in a wide variety of stunning single colors as well as ready-made, custom blends. Simply purchase a pack, flat, or more of one of these lovely color combinations from your neighborhood garden center, plant them, and you’ll instantly look like a pro at garden design!
- Don’t Barricade Me In. Unless it’s in a bouquet! Petunias called Tidal Wave practically sprout before your eyes, producing a floral hedge with a plethora of Cherry, Hot Pink, Purple, or Silver blossoms. Tidal Wave petunias will grow an additional two to three feet upward like a vine if planted in a small area with additional support, like a fence or a shrub.
- Follow the flow. For a sparkling look, combine a rainbow of hues and put Wave petunias in a sea. Make a river or a tiny stream of flowers that runs the length of the yard. Just visualize the blooms as smoothly rising bands of free-flowing color around your yard.
All Wave petunias prefer sunny locations, ideally with at least six hours of direct sunlight, but keep them from drying out. In particular when grown in containers, wave petunias require regular feedings of an all-purpose fertilizer because they are hungry plants.
