Wave® Petunia Plant Pointers
Wave Petunias are beautiful and low-maintenance flowers that will spread like you've never seen before. Here are a few pointers to ensure that your gorgeous Petunias will bloom all season long for you.
Picking a Location
You want to choose a location that allows your Wave Petunias at least six hours of sun every day. These flowers need the sun’s warmth and energy to thrive. If you can give your petunias this amount of sun, it is very likely they will bloom all season. Be sure that when you move your Wave Petunias from the container that you bought them in, you maintain the same plant depth as the original pot or pack. Place it in the ground all the way up to its soil line. Also, make sure to pack it in nicely.
Also, if you can add organics or compost to the soil in the location where you are planting your Wave Petunias, your Petunias will be very happy. Doing so helps the petunias to work their way into the soil, which in turn allows them to be better hydrated and fed.
While your Wave Petunias will thrive in the garden, they also can do well in hanging baskets, large containers, and window boxes. Just be sure that they are getting the right amount of sun. If you want a lush, full container display, place 1 to 3 plants in a 10 inch or larger container, hanging basket, or patio planter.
Don’t let your Wave Petunias dry out between each watering. They need plenty of water due to their aggressive spreading nature. Keep in mind that containers dry out quicker than in-ground beds. Avoid watering your plants directly overhead as this can cause the foliage to burn in the hot sun. If possible, water your plants in the morning so that the foliage can dry before the heat of the day sets in.
The more established the plant, the more heat tolerant it will be. If you are able to, plant your Wave Petunias as early as possible before the hot weather comes. This way they’ll establish their root systems, which will improve their heat tolerance.
You will want to make sure that when you plant your Wave Petunias, you follow the following directions for spacing. Wave Petunias grow according to how you space them. If you space them 12 inches apart, they will form a dense, mounded hedge. However, if you space them about 18 inches apart, they will perform as large mounded bedding plants.
Before placing your petunias in the ground, add a dose of slow-release or granular fertilizer to the hole where you are planting your petunias. This will help to ensure that your Wave Petunias get off to a strong start. (Be sure to follow the dosage instructions on the label.)
Keep in mind that a regular routine of liquid fertilizer (about every 10-14 days, as needed) when you water will keep your Wave Petunias happy and healthy. This will give them the necessary nutrients for their continual and aggressive sending up of new branching and blooms.
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.
Containers and hanging baskets require fertilizer more often--sometimes twice a week in the summer to ensure optimum growth and health.
If your Wave Petunias get more overgrown or leggy in your landscape than you prefer, you can cut them back. (Just be sure to fertilize them about every two weeks and they will bounce right back.) However, if you prefer not to, you definitely do not need to cut the petunias back. The Wave Petunias are very low-maintenance and do not require any deadheading. The faded blooms will simply dry up and drop off the plants on their own, with more appearing continuously all season long.
If you notice that bugs are eating your petunias, simply purchase a garden pesticide that is recommended for petunias or flowers in general. Be sure to follow the instructions on the label, and the insect problem should be taken care of.
What to do When Wave Petunias Start to Seed
If you notice that there are black spots on your Wave Petunias’ leaves, and these spots are not moving, then your Wave Petunias are most likely starting to seed. (If these black spots are moving, then those are probably bugs--see above.) This is a common occurrence and, to make sure that the plant continues to bloom, you only need to make sure to fertilize them. This especially happens during the summer months when the temperatures are high and you have to water them more frequently.
