Here are some basics to help you succeed with petunias in your garden! The three big requirements are: Sun, Water, and Fertilizer. These are the three things you must keep in mind to have the best performance from your Supertunias.
Petunias need AT LEAST 6 hours of full sun a day for best results. So from 10:00am – 4:00 pm minimum.
Think of it this way, for Supertunias sun = energy – they need this energy to keep producing more flowers, because flowers require energy to produce. The more energy the plant has the better the flowering. With sun and Supertunia more is almost always better!
Petunia plants like consistent water. They can tolerate a little more or a little less, but the key is to be consistent. The more they receive their needed water on a regular basis the more reliable they are in producing new flowers.
Things get dicey when someone forgets to water and plants become very dry, or if someone gets carried away and makes the plant soggy. Those extremes are harder for the plant to deal with than regular watering. When the plant is stressed by the extremes, they stop producing flowers and just try to survive – you never want your flowers to have to make that decision!
The amount of water a plant needs is always changing, here are tips for watering your petunias:
