Wave Petunia Plant Care Tips:
1) Watering Of Wave Petunias:
The water level of your pot should be at least 1/4 inch above the top of the soil. If it’s not, then add some pebbles or sand to fill up the space between the bottom of the pot and soil.
Soil should be damp but not wet from rainwater. If it’s too dry, then sprinkle some compost over the soil.
2) Growing Method:
You can grow wave petunias either in a sunny location or under shade. You can also grow them in containers, but they will need to have plenty of room to spread out their roots.
They prefer full sun and partial shade so choose the right growing conditions for your area.
3) Pests And Diseases:
Wave petunias are susceptible to powdery mildew, which attacks leaves and stems. The fungus produces white spots on the affected parts of the plant.
These spots may look like little flecks of dirt when they’re small, but they become larger as the disease progresses. Powdery mildew affects all types of plants including vegetables, fruits and flowers. There are different organic sprays on the market to kill powdery mildew, or you can try making your own from ingredients such as half a cup of chlorine and a quarter cup of vegetable oil.
4) Great Companions For Wave Petunias:
Some great companion plants for wave petunias are known to attract predator insects which will eat the pests that prey on petunias. Lavender is one of the best companion plants for wave petunias.
You can also grow basil, sage, and mint to repel mosquitoes around your petunias.
5) Fertilizing Your Wave Petunias:
A liquid fertilizer every two weeks is best for your petunias. Use a fertilizer with low levels of nitrogen and high levels of phosphorous and potassium.
Too much nitrogen causes lots of foliage and not enough flowers.
6) How To Plant Wave Petunias:
You can plant wave petunias at a depth equal to 2 to 2.5 times the size of the plug that you bought.
They like well drained soil and so should be placed in a raised bed with some organic material mixed in or some pebbles to allow for drainage.
7) Pruning Your Wave Petunias:
The first thing that you should know about pruning is that it isn’t necessary at all. You can simply let the flowers fade and drop off naturally.
If, however, you do decide to prune your petunias there are a few rules to follow: Always cut back to a pair of buds. These buds will then grow into new stems and flowers. It is best to wait until your petunias are done blooming before you start cutting them back.
8) Deadheading Your Wave Petunias:
As previously mentioned, deadheading is the practice of removing spent flowers to keep your plants looking neat and tidy. Each wave petunia stem will have between one and four buds, with each bud producing a new flower.
When all the buds on a stem have been used up that stem has spent itself and so you should cut it back to a pair of buds. If you wait until your petunias are done flowering you’ll get a better idea of which stems to cut back.
Good luck with your wave petunias!
