Do Wave Petunias Come In White?

How Do You Harvest Wave Petunia Seeds?
White-wave petunias blooms produce seeds in a seedpod which is located at the bottom of the flower. The seeds can be harvested when the plant is fully mature and fading. Additionally, you can also pinch the flowers to extend the bloom period. Alternatively, you can allow a few of them to die naturally to continue your seed harvesting endeavor.
Here are a few tips:
– When harvesting, ensure that you pinch the blooms at the base to remove them without damaging the plant.
-Thereafter, leave them out in a shallow tray to dry completely.
– After that, store the seeds in an airtight container for a few days.
– After this time you will see that the pods will split open, releasing the petunia seeds.
– The seeds can be stored in a cool, dry place if you’re not planting them immediately.
Note: Petunia seeds need a lot of light to grow because they are tiny. You should plant the seedlings about a foot apart when they have about three leaves. Use a container potting mix that will drain well if you’re planting in containers. Because petunias can withstand some heat, you shouldn’t have to worry about watering them frequently. Once a week, thorough watering should be enough unless there are prolonged periods of drought in your area. Remember to avoid shallow irrigation. This is because it will promote shallow roots.
Can You Save Seeds from Wave Petunias?
Yes, you can save seeds from white-wave petunias. To do this, you should begin by growing them in the appropriate conditions.

This is because petunias prefer well-drained soil and direct sunlight. You can also pinch the flower tips back as they grow to encourage bushy growth. Below are a few ideas on how to save wave petunia seeds.
Near the end of the growing season, it is vital that you select healthy, disease-free petunias for seed production.
To allow seed pods to form naturally, stop deadheading your petunia plant. Keep in mind that when the bloom fades and dies off, the seed pod begins to form.
Finding the seedpod
Keep an eye on the flower as it perishes and the petals naturally fall off. During this time, it is advisable to not remove it from the plant. The seedpod is encased in the calyx, a bulbous structure at the base of the flower.
Check on the calyx daily as it swells with developing seeds at which time it will turn from green to brown. Also, keep an eye out for signs of cracking. When the seedpod begins to crack, cut it off the stem as this is an indication that the seeds have reached full maturity. Any soft or damp pods should be discarded because they will cause mold which will flaw the seeds.
Allow the seeds to dry out completely. You can spread them out to dry on a tray. Be sure to leave plenty of space between them for air circulation. Store the pods in a cool, dry place away from direct sunlight for about a week.
Testing for dryness
To test if the pods are dry, take some between your fingers and squeeze them. You will know if the seeds are dry if it is difficult to break. To release the tiny seeds into the bowl, squish the pod. Remove any husk and debris.
Place the seeds in an envelope or small paper bag when storing them. These seeds can be stored for up to 5 years in a cool, dry place.
Do Wave Petunias Come Back Every Year?
Although petunias are perennial plants, they are commonly grown as annuals because of their growth pattern. These plants will often survive and even bloom during the winter months in year-round warm climates. However, if the temperature becomes too low, it can reduce the time of their flowering period. If you find your white wave petunia wilting, here are a few things you can do to avoid this and keep them thriving.
If you live in a colder climate and want your petunias to grow back in the spring, keep them indoors during the winter.
If your wave petunia is drying out, the first thing you should do is make sure you’re giving them enough water. This is because they require frequent watering when grown in containers or in the ground.
White Wave Petunia Care
Reviewing the care you’ve been giving your plant is essential. Although petunias are easy to grow, one unintentional oversight can have a negative impact on how well they thrive. Their primary requirement is plenty of sunlight as they prefer at least six hours of direct light per day.
Establishing a regular fertilizing schedule should help you remember when it’s time to feed your petunias. You should fertilize once every three weeks for regular, in-ground petunias, once a week for spreading types, and once every two weeks for container plants. Over-fertilizing could lead to pest and disease problems so ensure that you follow the proper directions.
