Any advice for planting Cool Wave Pansies in the garden?

Cool Wave Pansies do not need to be put close together. Per square metre you only need 9 plants to fill out a garden bed full with flowers (compared to 24 standard Pansy plants). Therefore try and leave at least 30cm on each side for them to spread out.

How should I plant Cool Wave Pansies in containers?

Cool Wave Pansies need room to spread and trail, therefore plant your Cool Wave Pansies around the edge of the container or basket with plenty of space in between plants and from the edge of the container or basket. For example, 3 Cool Wave Pansy plants is easily sufficient to fill a 30cm basket or container.

What is the best use for Cool Wave Pansies?

Plant into hanging baskets or large pots to create a centre piece attraction for your garden. Cool Wave Pansies will spread out to fill the basket and pot with flowers and will trail over the sides bringing colour to your garden when all other plants are hibernating or dead.

 

Cool Wave also grows well in beds and landscape. They will trail and spread and cover the ground easily, so make sure you do not plant your Cool Wave in such a high density as you would normally plant your standard pansies. Check our advice for planting Cool Wave in the garden.

Do Cool Wave Pansies need to be "pinched"?

No

Do I need to "deadhead" or remove the old blooms off of my Cool Wave Pansy plants?

Cool Wave Pansies flower abundantly. New flowers will cover old flowers. Deadheading however will promote growth and flowering even more. It will ensure that more energy is put into growing and spreading.

How can I produce the most spread/trail on Cool Wave Pansies?

To effectively produce the most spread and trail of Cool Wave Pansies, you must regularly feed and water them. Then ensure that the older flowers are picked regularly to enable more energy to go into growing.

How cold tolerant are my Cool Wave Pansies?

Cool Wave Pansies have been trialled over a number of years in different locations of the world and have been seen to easily cope with temperatures as low as -25°C / -13°F, better than any other standard pansy. They will stop growing and flowering, they will look frozen, leaves and stem may turn brown. However, Cool Wave will revive and start flowering again quickly after the frost is gone and spring is coming. Because Cool Wave start to flower already when the days are still short, it is a true messenger of spring approaching.

Should I still water my Cool Wave Pansies during days of frost?

No, during days of frost, when the soil is frozen, plants are not active and do not need watering. It is better to leave them and wait until the frost is gone. Cool Wave plants become active again soon after the frost is gone, the soil is warming up and spring is coming. Then it is time to make sure your Cool Wave is not drying out, and to start watering and fertilizing them regularly again.

What is the minimum temperature that Cool Wave Pansies can handle?

Cool Wave Pansies have been trialled over a number of years in different locations of the world and have been seen to easily cope with temperatures as low as -25°C / -13°F, better than any other standard pansy. If your part of the world goes lower in temperature than this, you can help Cool Wave Pansies by bringing them closer to your house, planting them in a larger container or even covering them with a breathable warming fabric during the coldest days which is available from most good garden centres.

What should I do if the leaves start turning yellow?

Yellow leaves could be a combination of things. The plant might have had drought stress over a number of days and need more frequent and regular watering. Another cause of yellow leaves might be that your Cool Wave plants need feeding. In this case it is best to present a combination of slow release and water soluble fertiliser.

When should I water and fertilize my Cool Wave Pansies?

Cool Wave Pansies have remarkable rebound ability if plants temporarily wilt. However, for optimal flower performance, Cool Wave Pansies like to be fed and watered regularly, especially during warmer weather. Therefore we suggest you use a combination of slow release fertiliser with a dose of water soluble fertiliser once every 2 weeks.

I found bugs eating away at my Cool Wave Pansies! What should I do?

Cool Wave is not very sensitive to bugs and since they grow vigorously, they will easily withstand a small infection. Check your local garden store for advice on bug treatment in your area. Respect local regulations.

My Cool Wave Pansies are dying! What's wrong with them?

If you have followed the planting tips on this website there usually should be no such problem with your Cool Wave Pansies. If you are having problems maybe the plant is not getting enough sunlight, maybe it’s not getting enough water or maybe it’s not getting enough food. But don’t panic, your Cool Wave Pansies are very resilient and with a little bit of tender loving care they will come back.

 

Frost will cause Cool Wave Pansies to stop growing and flowering. If frost only occurs during the nights, Cool Wave will still grow and show flowers. Once the frost deepens, Cool Wave Pansies will wait for better weather. During a very harsh winter Cool Wave Pansies will look as though they have died but very surprisingly as soon as the weather warms up again Cool Wave Pansies come back to flower your garden again through until well into the Summer months!

My Cool Wave Pansies aren't growing with the habit I expected. Any ideas?

This could be several things. Maybe the plants have been spaced incorrectly and therefore have not got enough space to spread. This will cause your plants to grow upright rather than across. Other reasons could include poor sunlight which will restrict growth but it could also be poor access to water and poor access to food.

De bloemen van mijn Cool Wave Viooltjes zijn heel klein geworden, waarom?

Hoewel Cool Wave Viooltjes kunnen bloeien tot ver in de zomer, zullen de hogere temperaturen er wel voor zorgen dat de bloemen steeds kleiner worden. Zodra dit gebeurt, kunt u overwegen uw Cool Wave Viooltjes te vervangen door verse Wave Petunia’s die dol zijn op de warmte!

The leaves on my Cool Wave Pansies have gone purple/yellow, what does this mean?

This means that they are not getting enough fertiliser. Cool Wave produces a mass of flowers and a massive plant body. To build all this colour, Cool Wave Pansies are heavy ‘feeders’. The full potential of Cool Wave Pansies will be realized more easily when you fertilize regularly. Apply a liquid fertilizer every 10 to 14 days or use a combination of liquid and a slow-release fertilizer. Always follow the recommendations shown on the labels.

My Cool Wave Pansies are starting to seed. Why is this happening?

Cool Wave Pansies will go to seed eventually but as long as you water and fertilise them regularly they will continue to grow and bloom. It is a good idea to pick the old flowers off the plant to stop them going to seed, new growth and flowers will appear very quickly after this.

Can I save the seeds from my Cool Wave Pansies and plant them next year?

It is not recommended that you save the seeds from your Cool Wave Pansies. Each plant is a well-balanced hybrid plant and seeds of this hybrid won’t recreate the same vigour, style and strength of plant when compared to the original.

I can't find Wave in my area! Where do I go to find them?

If there is not a garden centre in your area that sells Wave, you can order Wave plants via mail order companies that will ship directly to your home.

You can also visit your local retailer and make a request to order Wave for the next growing season. If your store does not sell Wave, ask them why. Send us a quick note and let us know what they said by using the contact page.

Can I plant Wave Petunias in the same garden bed every year?

It is not recommended that you plant your Wave Petunias in the same place every year. You'll see the best results if you do not plant them in the same bed two consecutive years. Move them around your garden. They are great in containers and baskets or try some in another sunny bed. For baskets and containers, dispose of the old soil and replace with new, fresh potting soil each year.
Rotate your Wave Petunia beds and you'll enjoy the best performing plants year after year. Farmers have been practicing crop rotation with great success for years.

Where is the best place to plant Wave Petunias?

Choose a bright, sunny location with at least 6 hours of direct sunlight. Sun is a MUST to keep your plants blooming and looking their best all season.

Any advice for planting Wave Petunias in the garden?

A few things to remember...

  • Maintain the same plant depth as the original pot or pack
  • Space Wave and Easy Wave 12 to 24 in. (30 to 60 cm) apart in garden beds
  • Tidal Wave Petunias grow according to how you space them - Spaced 12 in. (30 cm) apart, they form a dense, mounded hedge - Spaced a little farther apart – about 18 in. (45 cm) – they will perform as large mounded plants.
Can I re-plant my Wave Petunias? And if so, will they grow again next year?

Wave Petunias were really developed to be planted once during the season and then allowed to die after the first frost. In very mild climates like Southern Florida, Texas and coastal Southern California – Wave Petunias will grow through the Winter. The rest of North America gets frost during late Autumn and Wave does not survive the Winter months, especially in containers and baskets. We recommend starting fresh each Spring with new, young plants for the best performing petunias!

Do I need to "deadhead" or remove the old blooms off of my Wave Petunia plants?

Wave Petunias are low-maintenance; you don't have to cut the plants back or remove dead flowers. The faded blooms will dry up and drop off the plants on their own, with more appearing continuously all season long.

Do Wave Petunias need to be "pinched"?

Wave petunias, if grown as recommended in full sun (at least 5-6 hours per day) and regularly watered and fertilized (once a week with liquid feed, or with slow release fertilizer per directions), should not require pinching.

How heat tolerant are Wave Petunias?

The more established the plant, the more heat tolerant it is. If you can, plant your Wave Petunias early enough to enable them to establish strong root systems before high temperatures set in.

If I bring my Wave Petunias inside for the winter and put them in a sunny spot, will they survive?

Wave Petunias really perform best when planted outdoors during the Summer months. The conditions indoors, even in a sunny spot, are tough on Wave Petunias, as with many other Summer garden plants. We recommend starting fresh each Spring with new, young plants for the best performing petunias!

Should I use mulch around my Wave Petunias?

Using a mulch protects the roots and conserves moisture, however, Wave Petunias form their own solid mat of colour as they grow.

When should I water and fertilize my Wave Petunias?

Don't let your Wave Petunias dry out between watering’s. They need plenty of water, but keep in mind that the soil in beds and containers must be well-drained and containers dry out faster than in-ground beds. If possible, water your plants in the morning so the foliage dries before evening.

Wave Petunias are heavy "feeders." The full potential of Wave Petunias will not be realized from hungry plants. Apply a liquid fertilizer every 10 to 14 days or use a combination of liquid and a slow-release fertilizer. Always follow the recommendations shown on the labels!

I found bugs eating away at my Wave Petunias! What should I do?

We suggest you purchase a garden pesticide that is recommended for petunias or flowers in general. Follow the instructions on the label and it should control the insect problem accordingly.

I have black spots on the leaves of my Wave Petunias. What does this mean?

Check closely to make sure it isn't dirt or even seed from the plant. It may be an insect, in which case a pesticide may be needed. Consult an expert to identify the pest and suggestions for the best treatment.

My Wave Petunias are dying! What's wrong with them?

We recommend that you rotate bed plantings every year and replace the soil in containers. We have found that this simple step minimizes the loss of plants. Wave petunias require at least six hours of full sun to perform at their best.
Wave Petunias are heavy "feeders"! If possible, mix a tablespoon of dry or slow-release fertilizer with the soil or into the hole when you are planting your Wave Petunias. This will provide constant food as the plant grows. If you are using a standard fertilizer, like Miracle Gro®, try fertilizing twice as often as usual to promote new growth. However, even after increasing the feed, it may take as long as 10 to 14 days to see significant growth throughout.

Also, maintain adequate moisture. The plants should not be so dry that they start to wilt. Wilting is not only a sign of the plant needing water, but can also mean that the roots are dying. The best practice for watering is to test the soil by poking your finger down in the soil at least 2.5 to 3 in. If it's still moist, you do not need to water. During the hottest months of the Summer, you may need to water every day or twice a day for small containers. Check for insect damage. Use the recommended insecticide for the specific pest or another control you prefer.

If you have done all of this and your plants are still not performing well, it may be best to take one of your plants to a local nursery to help determine the possible cause of the problem. You can also contact a Master Gardeners or University/Extension Agent in your area.

My Wave Petunias aren't growing with the habit I expected. Any ideas?

There are two things to keep in mind: the natural growth habit of the plant you purchased and the way you are fertilizing and watering them.

As you know, there are different series of Ride The Wave Petunias that have different growth habits. Double check the tag to make sure you know which Wave series you are growing. You can get more info in the "Which Wave is which" Section of this site.

Also, it could be how much you are feeding the plants. Again, Wave Petunias are heavy feeders and like lots of fertilizer to grow lush and strong. When planted in the ground, the plants get food from the soil, so you only have to fertilize every two weeks or so. Obviously, containers and hanging baskets require more feeding – sometimes twice a week during Summer.

Wave Petunias are starting to seed. Why is this happening?

Wave Petunias will seed, however, as long as you fertilize and water them, they will continue to grow and bloom normally.

If you continue to fertilize your plants, new growth will appear within 2 weeks. If they start looking "stringy," cut them back a few inches as long as you continue to fertilize them twice a week. It will most likely take at least 10 to 14 days to see results.

 

What should I do if the leaves start turning yellow?

If this happens to your Wave Petunia plants, it may be a sign the plant needs more fertilizer. A regular application of a soluble fertilizer every 10 to 14 days is recommended. Applying a slow-release fertilizer when you plant is also beneficial, although it may be depleted by late Summer. The use of a soluble fertilizer throughout the growing season is recommended, even if slow-release has been used.

Can I save the seeds from my Wave Petunias and plant them next year?

Since Wave Petunias are "hybrids" – crossing two "parent" plants to get a specific "offspring" – the plants you purchase from the garden centre each year are really one-of-a-kinds. Any seed that is taken from Wave Petunias will not grow into the same Wave plant and very likely will not perform in the same way.

It is best to start fresh each Spring with new, young plants for the best performing petunias!

Why aren't there any yellow Wave Petunias? Can I expect to see this color in the future?

It is a difficult task to breed yellow petunias and even more of a challenge to make sure the plants have a spreading habit like the rest of the Wave series. We are currently working towards developing a yellow for the Wave Family and will be sure to make a large announcement when it's ready to be introduced.

Wave Petunias come in other unique colours – like Blue and Salmon – so you have some alternative choices until the yellow is unveiled!
