How frequently do I need to water hanging baskets of petunias?

How frequently to water petunias in hanging baskets is one of the most frequently requested questions. The solution is straightforward: water when the top inch of the soil feels dry to the touch. During the summer, hanging petunia plants will probably require daily watering, possibly twice a day if there is a lot of heat and/or wind. Water the area thoroughly enough so that the extra water drips through the drain hole. Never let the ground be damp all the time. Your petunia roots are probably going to decay in this kind of wet environment. Water the soil, not the leaves, if at all feasible. Wet leaves may become infected by fungus.

Feeding Petunias

Use a water soluble fertilizer for flowering annuals to feed petunias once a week. Petunias consume a lot of food since they grow quickly and have several blooms.

This kind of watering prevents me from draining away nutrients as much as I would if I were to use regular water.

For petunias to be grown successfully, there must be enough sun. They require at least five to six hours of sunlight, but full sunlight throughout the day will improve their performance. Plants will produce fewer blooms the more shade they receive. Make sure to rotate your flower basket every week if it is hanging from a porch eve so the darker side may get some sunlight.

If you don’t get rid of faded flowers right once, the plant will go to seed and stop blooming early. In addition, the plant will just appear lot prettier.
