Petunias are one of the most popular garden flowers. Petunias require little maintenance and come in a huge range of colors, including black! If you want your flower bed to burst with color, it is the perfect flower to include.
Even though they are colorful, you’ll know that those blossoms tend to die off quickly, leaving an unsightly deadhead on top. Gardeners should remove these deadheads until you want the plant to stop producing blossoms, leaving a green stem in your garden for the rest of the growing season. The only way to ensure your petunias continue to produce colorful blossoms all season is by learning how to deadhead petunias. Let’s take a look!
Why Do You Need to Deadhead Petunias?
Perhaps you selected petunias because you wanted a flower you could plant and forget. While petunias are very easy to care for, deadheading is important. The goal of any plant is to reproduce itself, which is why it forms seeds towards the end of its lifespan. Once the petunia blooms turn brown and die, the plant turns its energy toward creating a seed pod filled with seeds.
Unless you want the seeds to form so you can grow your petunias at home, clipping off the deadheads redirects the energy back to creating blooms. The plant will stop forming the seed pod and go back to producing those colorful blossoms. If you continue to do this throughout the growing season, your plant will continue to grow and blossom with color all season!
Which Varieties of Petunias Need to be Deadheaded?
Grandiflora: These are largest petunias with trumpets as wide as four inches each. Most of the older varieties are Grandiflora with the ruffled petal edges. Some of the newer types, such as Surfinia Series, are energetic growers and don’t require deadheading as often. If you purchase the older types, they are more likely to experience damage from rain and wind. Opting for a sheltered location will let them live longer.
Multiflora Types: If you select a multiflora petunia, the blossoms tend to be two inches wide. These species are tough, weather tolerant and more numerous in number. Carpet Series and Primetime Series are two popular choices in this category. Instead of needing deadheading, multifloras are self-cleaning flowers that let the dead blossoms fall right off when done.
Floribunda Petunias: Floribunda petunias fall between Grandiflora and Multiflora in the size of the flowers. They are strong growers, but they are not self-cleaning, so you will need to spend time regularly deadheading the plants.
Floribunda Petunias: Floribunda petunias fall between Grandiflora and Multiflora in the size of the flowers. They are strong growers, but they are not self-cleaning, so you will need to spend time regularly deadheading the plants.
Wave Petunias: Many people purchase wave petunias because they create a huge mass of color that lasts for an entire season. These petunias differ from other varieties because they reach five to seven inches tall, but they spread out almost three feet wide! Wave petunias come in a multitude of variations including Cool Wave, Shock Wave, Easy Wave, Double Wave and Tidal Wave.
The best reason to purchase Wave petunias is that they require no deadheading. Yes, you read that correctly! The flowers wilt and dry up, then they will fall off on their own. Soon, a brand new blossom takes its place with no work from you.
Wave petunias will need pruning at some point throughout the season because it will look leggy around midsummer. Cut them back to half of their length.
Things You Need to Deadhead Petunias

-> Pruning shears.
How to Deadhead Petunias?
Learning how to remove deadheads is quite easy. Once you get started, it is a monotonous task that even children can do if taught properly. There are different methods, such as pinching and using shears. Let’s take a look.
Check the petunias: Each week, you should take a few minutes to look over your petunia plants. They won’t all deadhead at the same time. You are looking for flowers that look to be wilting. Some of the petals may have dropped to the grow. If you waited extra time, there could be seedpods along the stem.
Try Pinching First: Newer gardeners may feel more comfortable pinching deadheads rather than using shears. Cutting your beautiful plant can seem scary. Look for the new blooms which are typically above the dead ones. Pinch about ¼ inch above the bud. Using your thumb and forefinger, gently pull. Deadheads come off very easily.
Move onto Using Pruning Shears: Once you are used to pinching deadheads off, move onto the shears. They are effective and easy to use once you feel confident. Make sure that your shears are sharpened. Plants handle a sharp cut better.
Repeat with Each Plant: Depending on the type of petunias you grow, there may be several dead blossoms on each stem. Some will only have one. You should carefully examine each plant, so you don’t miss one. The process you completed before is the same for each one!
Leggy Petunias: Mid-summer, you might notice that your stem is getting leggy and hanging towards the ground. If you see this, you should pinch off the growing tips. Hold the stem gently and look for the thickest bud. This part of the plant is actively growing because it is typically at the top of the plant.
Pinch it between your thumb and forefinger, removing it totally. You could also use shears to cut off the top three to five inches. Although it might seem wrong to take off a living part of the plant, it is necessary to ensure proper and healthy growth.
TIP: Petunias in containers are more prone to leggy development. If you want to keep these petunias looking beautiful, you should deadhead them more often. Watch them closely and prune when growing too tall.
Compost: After you finished deadheading all of your petunias, add the dead blossoms to your compost. There is no reason to throw them in the trash when they are a great material for composting!
Tips for After Deadheading Petunias
After you remove deadheads or prune the petunia plant, you should use a 10-10-10 fertilizer that is water soluble designed for blooming plants. Also, make sure to give them a healthy watering because it encourages new growth.
If you are using pruning shears, clean them after each use. Sometimes, plants have diseases or fungi. Using uncleaned shears could transfer diseases.
Petunias need as much sunlight as possible. If your plants aren’t producing blooms, you might need to replant them in a sunnier area of the garden.
Conclusion
Every garden needs to have a variety of petunias. They are inexpensive, easy to grow and spread color throughout your flower beds. Learning is an easy task. Once you have done it the first time, it will seem like a simple chore. It is so easy to understand that you can pass the task onto your children!

Wave Petunias

Want to know why the ‘Wave is all the Rave’?

By Anna Randall

Wave Petunias are all the rave! They are a spectacular variety that have been bred for their prolific spreading growth habit, big beautiful blooms that bloom profusely throughout the growing season with easy care. The beauty of this plant makes it a stand-alone, however the fact that no deadheading is required unlike original varieties of petunias, makes the Wave petunia a genius species!

What flower could be better? They stand up to rain, humidity, heat, and other environmental stresses better than other varieties, making them a gardener’s delight! Less susceptible to botrytis and mold issues is another perk to this plant. Wave Petunias keep their lush, full habit even in the dog days of August when every other plant around them wilts at noonday and struggles to keep going. Keep them watered and fertilized and they are like a gift that keeps on giving!

They even come in different varieties for different needs: trailing, mounding, and spreading. They are excellent for containers, hanging baskets or in the ground.

A few points to remember when planting:

Don’t over-pack your container. (I have a tendency towards this, wanting an instantly full basket, – resist the urge. 😉) A few plants will go a long way, it is recommended that you use 3 Waves in a 10-12-inch container. The larger the container the more plants you can put in. Wave Petunias will fight for the nutrients they need to spread and cascade, so make sure they have space to grow. They will fill in fast and make you happy!

Fertilizer is a must. Plants that are vigorous growers are hungry plants. They need plenty of food to give them the energy they need to make those beautiful big blooms. If you notice the leaves are turning yellow, that is a sign that your plants need some fertilizer. Adding fertilizer to their water every ten – fourteen days is a good idea and will allow your waves to spread and bloom all summer.

Remember that containers dry down faster than the garden. Because planting in containers limits the roots ability to seek out hydration it is important to keep them happy with water. In the heat of summer, your container may need water twice a day. Dry down between watering is tolerated by Waves but don’t let them wilt. (I say, “don’t let them cry”) By the weight of your container and checking moisture levels by reaching into the soil with your fingers you will know whether your Petunias are thirsty or not.

Good drainage is key. Wet roots do not make a happy plant and will encourage disease and or cause your plants’ roots to drown. There should be enough drainage that excess water can easily run out.

Waves need sunlight. At least six hours a day of sunlight is ideal for this sun-loving plant. They will perform best when they soak up the sun’s energy and warmth and give you the show you are looking for.

Give these gorgeous Wave petunias the care and love they need and they will give back to you all summer long!

“The world is full of poetry. The air is living with its spirit; and the waves dance to the music of its melodies, and sparkle in its brightness.” James Gates Percival

Petunia

Petunias are one of our most popular summer bedding plants, flowering throughout summer until the first severe frosts of autumn. Their mass of flowers bring lots of great colour to gardens.

The compact, bushy varieties are perfect for planting in beds and borders and the trailing types brighten up hanging baskets and for flowing down the edges of containers.

There is great variety in petunia flowers: a wide range of colours; both single and double blooms; smooth or ruffled petals; solid single, striped, veined or picotee-edged colours; and even fragrance. Recent breeding has also removed the scourge of old petunia varieties – turning to mush in a wet summer.

Petunias are perennial, although most bedding types are grown as annuals from seed each year. The trailing varieties, such as Surfinias, are perennial and are grown from cuttings or new plants.

How to grow petunias

Cultivation

Petunias prefer to be grown in full sun, although during hot, sunny summers they will tolerate light shade. They grow best in a fertile, moist but well-drained soil. Dig in plenty of organic matter – such as garden compost, well-rotted manure or other soil improver – especially in very well-drained sandy soils to hold moisture.

Petunia varieties

Bedding varieties are either grandifloras with larger flowers or multifloras with smaller flowers that hold up better in the rain.

Spreading or trailing petunias include Surfinia, Wave, Tumbelina, Supertunia and Cascadia series.

Sowing petunias

The annual or bedding petunias can be grown from seed sown indoors with warmth in spring in cell trays, seed trays or small pots at a temperature of 18-24°C (65-75°F).

When large enough to handle, prick out plants individually into cell trays or small pots and grow on at a temperature of 50-65°F (10-15°C) in good light.

Gradually acclimatise the plants to outdoor conditions for 7 to 10 days before planting outdoors when all risk of frost has passed.

If you don’t have the facilities to grow them from seed, young petunia seedlings are available from garden centres and mail order suppliers in late winter/early spring.

Planting petunias

Petunias are planted out in May/June after the danger of frost has passed.

Dig a good sized planting hole, big enough to easily accommodate the rootball. Add a layer of organic matter – such as compost or planting compost – to the base of the hole and fork it in.

Place the rootball in the planting hole and adjust the planting depth so that it is planted at the same depth as it was originally growing (except hardy fuchsias) and the top of the roots are level with the soil surface. Mix in more organic matter with the excavated soil and fill in the planting hole. Apply a granular general feed over the soil and water in well. Applying a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or similar over the soil will help maintain soil moisture and keep down weeds.If you have a warm greenhouse, you can plant up containers and baskets in spring and grow on the plants, ready to place outside in late May/early June. This way you’ll have flowers earlier in the summer.

Suggested planting locations and garden types

Flower borders and beds, patios, containers, city and courtyard gardens, cottage and informal gardens.

How to care for petunias

Keep the soil moist by watering regularly during prolonged dry periods in summer. Plants in containers will need regular, possibly daily watering – the aim being to keep the compost evenly moist. But don’t overwater, as too much water will cause the plants to become leggy with few flowers.

Feed regularly throughout summer with a liquid plant food to ensure a continuous supply of flowers. A high potash liquid plant food will encourage more, better blooms over a long flowering period until the first autumn frosts.

Removing faded flowers and any developing seed pods will prolong the display. Straggly plants can be cut back quite hard and then fed with a liquid plant food to produce fresh new growth and a profusion of flowers.

In the autumn, once damaged by frosts, bedding petunias are best dug up and composted.

Overwintering petunias

Perennial, trailing varieties can be cut back hard in autumn, tidied up to remove dead or damaged growth and carefully lifted. Pot them up in pots just big enough to take the rootball and some fresh potting compost around the sides, and overwinter in a light, frost-free place – preferably a greenhouse or cool conservatory.

Propagating perennial petunias

Perennial, trailing varieties can be propagated from cuttings taken in March/April from overwintered plants or in August/early September.

Choose strong, healthy young stems that aren’t flowering. If you can’t find suitable growth, cut back hard one or two stems at the back of the plants to encourage strong regrowth. Take cuttings 7.5-10cm (3-4in) long, cutting just below a leaf joint, or node. Remove the leaves from the lower two-thirds of the stem and insert five or six cuttings in pots of gritty, cuttings compost to the base of the lowest leaves. Place the pots in a plastic bag or in a propagator and place somewhere in good light, but out of direct sunlight, to root.

The cuttings should have rooted in 2 to 3 weeks, when they can be potted up individually and grown on.
