Wave petunias are frequently grown in hanging baskets due to their propensity for spreading and continuous blooming. Wave petunias can be planted alone (single color), with other Wave petunias of different colors, or with other annuals to make a lovely bouquet of flowers and foliage.
Plants that grow well with Wave petunias in a hanging basket
Petunias in the wave family grow quickly. Therefore, it’s critical to pick companion plants for Wave petunias that can sort of stand on their own.
Here are a few illustrations of annuals that you would frequently find planted alongside Wave petunias. These plants either have height or are similar spreaders, which prevents Wave petunias from engulfing them. They need the same amount of sunlight and water.
Trailing Verbena
Wave petunias go very nicely with trailing verbena. The different bloom and foliage of these plants contrast well with Wave petunias, which will grow and cascade over the side of the basket like these plants do.
You also have extra color and design options if you decide to combine your Wave petunias with trailing verbena. Wave petunias come in a range of hues, but Trailing verbenas have some stunning bi-color blossoms that make them a wonderful companion plant for Wave petunias in a hanging basket.
Calibrachoa (Million Bells)
Another robust grower that Wave petunias shouldn’t supplant is Million Bells.
Although Million Bells are a relative of Wave petunias, they have smaller flowers that provide the hanging basket some diversity.
Geraniums
In search of height? A Wave petunia basket looks fantastic contrasted with geraniums. It looks nice to have a hanging basket with Wave petunias spilling over the edge and a Geranium growing up the middle.
Both plants can receive the sun they require to put up a spectacular display because geraniums can tolerate the sun as well.
Sweet Potato Vines
A common “spiller” for hanging baskets is sweet potatoes. Dark black and a yellowish green are two common colors. These accent hues work beautifully with a Wave petunia basket.
How far apart should trailing petunias be planted?
All petunias require average, slightly acidic to neutral soil with a pH of 6.0 to 7.0 at a location with at least six hours of direct sunlight each day and more, if possible. Peat moss, aged manure, or compost should be added to the soil at a depth of 2 to 3 inches and then thoroughly worked into the soil until it reaches a depth of 8 to 10 inches.
According to the Old Farmer’s Almanac, the area should also have good drainage because petunias thrive badly in too-wet soil. While multifloras only require a spacing of 4 to 6 inches, grandifloras and multifloras both require planting at a distance of 12 inches. Petunias that spread or trail should be planted at least 1 1/2 feet apart, even if they only reach a height of 6 inches.
How can you grow trailing plants in a hanging basket?
The trailing plants’ root balls should be wrapped in paper before being inserted through the holes. The compost in the basket should be level with the roots. Firmly place additional compost around the plants.
How are petunia hanging baskets planted?
Petunias thrive in regions with direct sunlight. Look for petunia varieties that produce flowers on long, flowing stalks, such as cascading petunias. Petunias are simple to plant in hanging baskets as long as you choose a robust container with at least one drainage hole.
A light-weight commercial potting mix should be used to fill the container because it will help the drainage. Never use garden soil because it soon compacts and is too heavy for adequate drainage. When planting, incorporate a slow-release fertilizer into the potting soil.
Should trailing petunias be pruned back?
Petunias’ tips can be pinched out to encourage new growth by releasing growth hormones. Pinch all petunias when you plant them in the garden since doing so aids new transplants in establishing themselves more quickly. Deadheading on time promotes a large number of flowers. The plant will substantially reduce the amount of fresh blooms it produces if you let the blossoms go to seed since it will believe its life cycle is over. Garden petunias are hybrids, not true from seeds, therefore there is no point in trying to let them reseed themselves.
How are trailing petunias maintained?
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 indoors with warmth in cell trays, seed trays, or small 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.
Select young, robust, vigorous stems that aren’t in bloom. Cut back one or two stems at the back of the plants severely to promote vigorous regeneration if you are unable to locate adequate growth. 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.
Can I plant as many petunias together as possible?
Although petunias can be planted at any time of the year, spring planting is the most popular. As long as there is no possibility of a frost, you can plant petunias. With the correct circumstances and maintenance, the plants will last into the fall. Remember that petunias planted later in the growing season won’t have highly established root systems and will require more frequent watering to withstand warm weather.
Containers make sense given that the soil dries out and heats up rather rapidly and petunias thrive in dry soil and warm weather. Petunia plants don’t care too much about the pots they live in. The plant will flourish as long as the container includes a drainage hole and room for the roots to spread out. In a 12-inch pot, aim to place no more than three petunias.
Unglazed ceramic and terracotta planters with pores allow the soil to dry out more rapidly, which is ideal for petunias. However, if the soil is drying up more fast, you will need to water the plants more frequently. As long as they include drainage, non-porous planters like glazed ceramic and plastic are also suitable options.
What occurs if petunias are planted too closely together?
Kole claims that if you place flowers too closely together, the plants get stressed and more susceptible to disease. Fungus develops if air cannot flow freely and the plants cannot dry out between waterings. The roots may decay. Insects then invade plants that have been stressed out.
In order to maintain a healthy distance between flowers, Level Green personnel will clip some plants as they mature if you decide to place them excessively close together.
How far apart should you space petunias?
Petunias should not be transplanted into the garden until the ground has warmed to about 60F and the risk of a frost has passed.
Grandifloras and multifloras should be planted about 12 inches apart in full sunlight, or a few inches closer apart in a more shady environment.
Petunias that spread and provide ground cover should be planted at least 1 1/2 feet apart.
Petunias need to be planted significantly closer together in containers in order to appear full and lovely from the beginning.
If it’s hot or windy with few clouds when you’re transplanting, consider offering some cover from the midday sun for the first several days. Pinch back grandifloras or multifloras when they reach a height of around six inches to promote the quick development of flowering side shoots. Avoid pinching or “spreading” millifloras or petunias.
How should a hanging basket be layered?
Mix the compost thoroughly with the recommended quantity of slow-release fertilizer and water-retention crystals. If the compost is dry, put in some water as well. The plants should be watered in advance and given time to drain.
- A thick layer of moss or another loose liner should be placed halfway up the basket in a large pot to balance it. Just enough compost should be added to cover the basket’s base.
- Push three to four trailing plants through the wire to “place” them in the basket’s sides. To prevent the compost from leaking out until the plants are established, make sure the lining material is well fitted around the base of the plant.
- More compost should be added, and it should be carefully pushed down over the plant roots.
- Continue to add compost, liner, and plant layers. Usually, two layers of plants, evenly spaced out along the basket’s sides, are sufficient.
- To prevent the compost from escaping, make sure there is enough liner around the base of the plants and that there are no holes in it.
- Add extra liner and plant the top of the basket once the sides have been planted.
- Working them in between the root balls of the plants that are in the sides, gently push the plants into the top of the basket. By this point, the basket may be quite crowded, so add compost around the roots as needed.
- Make sure the compost’s surface is free of any visible roots.
- Before hanging the basket up, give it plenty of water and allow it to develop for a few days in a chilly greenhouse or other protected area.
- Plant the top after adding compost to the pot.
- When applied along the sides, trailing plants should be oriented toward the pot’s edge.
- After you’ve planted the pot, give it plenty of water and give it a few days to develop in a cool greenhouse or other protected area before hanging it up.
What do you put in the hanging baskets’ bottoms?
Line the basket with a material that will help the soil maintain moisture before adding dirt and the plants. Options consist of:
- Coco coir liners are thick, durable, and absorbent since they are made from natural coconut husks. In order to keep the soil moist, it will store water and gently release it. Additionally, they have a pH balance that helps to maintain healthy soil, and they are biodegradable, so they won’t harm the environment.
- Even though it’s not as environmentally friendly, a plastic bag can be used as a temporary hanging basket lining. To limit the amount of moisture that evaporates along the sides, put holes to the bottom and cut it up so that it fits easily and coverlessly in the bottom of the basket. If your plants prefer a dryer environment, only line the sides of the basket. As a result, water can readily drain to the bottom. Lining the interior of the entire hanging basket is a good idea for plants that want to stay damp.
