Maintaining A Wave Petunia
The wave Petunia is a type of spreading Petunia that is very popular for use as groundcover because of the way it grows more laterally than vertically. Wave Petunias come in many colorful varieties and make excellent border flowers or even flower chains. While wave Petunia's are relatively easy to grow and maintain, there are some things that you should know.
Watering and Fertilization
Wave Petunias require constant watering - especially in hot or dry areas. You should never allow wave Petunias to dry out between watering. However, keep in mind that the soil used in your flowerbeds or containers must always also be well-drained. Remember that containers will always dry out faster than regular flowerbeds. Also, you should water your wave petunias in the morning if possible so that the leaves and flowers will dry before evening.
Wave Petunias require a lot of feeding. In order to get the most out of your wave petunias, you should make sure that they have plenty of nutrients needed for new blooms and flower growth. You should use a quality liquid fertilizer about every two weeks or so. Also, better quality slow release fertilizers work well and will allow you to fertilize with a liquid fertilizer only once a month or so.
Cutting Back or Deadheading
Wave petunias are one of the lowest maintenance petunia varieties available and generally do not require cutting back of the plants or removing dead flowers. Dead or faded blooms on wave petunias will dry out and fall to the ground on their own. Deadheading is not required, and new flower blooms will appear all during the growing season.
Saving Wave Petunia Seeds
While saving seeds from many varieties of petunias is an excellent idea, using seeds from mature wave petunias will usually create unexpected results. Wave Petunias are hybrid petunias that are created by crossing or breeding two parent types of petunias to produce a specific wave petunia offspring. So in fact, most wave petunias are unique or one of a kind flowers. Saving seeds from wave petunias will result in a different type of flower than the original and will usually result in a flower that performs differently or requires a different level of care or maintenance.
Replanting or Transplanting Considerations
Just as with many other types of flowers, wave petunias should not be planted in the same area every year. You should rotate your flower bed or garden plantings annually and also replace soil in pots or containers. Wave petunias are usually bred to grow once during the growing season and then die off in the winter. In some warmer climate areas, wave petunias will continue growth through the winter, but in other areas they will usually die during the first frost.
You should also keep in mind that wave petunias are less tolerant to being moved or transplanted than many other varieties of petunias. This goes for bringing the wave petunias inside as well. If you live in an area where the wave petunia will not survive during the fall or winter, you should simply start anew with fresh seeds the next spring.
