The most common cause of a yellow or wilted petunia is low light intensity. To be a petunia, the plant must receive a minimum of ten hours per day, six days a week. In this situation, you may not be receiving enough nutrients and light and the soil pH is likely too high. High pH, combined with high temperatures (over 100°F [38°C]), can also cause petunias to yellow.
How often should I water my hanging petunias?
When you water your hanging baskets, it’s best to let them dry out for a few days between waterings. If your potting soil is in good condition, it should hold excess water and won’t overheat.

What nutrient deficiency causes yellow leaves?
Deficiencies of some nutrients affect all plant tissues, but many are more common in certain tissues. N deficiency affects leaf color, resulting in yellow, light green, or dark green leaves that turn brown. Potassium deficiency results in dull, yellow leaf surfaces.
Why are my petunias wilting and dying?
Degree of wilting or dying can be due to heat and hot, dry conditions. Petunias are native to California and grow well there. When grown from cuttings or seeds, plants can take quite a bit of heat. Petunias require some type of repotting every so often, but when the soil is overly hot and dry, the rootlets can wilt.
Can you overwater petunias?
The answer is simple, If you want to water the plants with water in a week, you need to add 2 inches of water to each pot. You can add more water or the plants won’t be watered properly and you will end up with plants that need to be in the dirt to thrive..
Are you supposed to deadhead petunias?
Yes, it’s true – deadheading is essential for continued blooming. Deadheading will help keep your petunias flowering longer and reduce the risk of petunias flowers ending up on the ground – just cut off the flowering stems when they are brown – the rest of the stem can just grow and be replaced.
Why are my hanging baskets dying?
As winter turns to spring, your berry bushes and hanging baskets should turn into fresh fruits and vegetables. When your favorite flowering vines show signs of browning and wilted leaves, it’s time for a change of bedding.

Can yellow leaves turn green again?
When yellow leaves turn green you can tell because their green color becomes more pronounced. This might not be noticeable on a single branch or a few leaves, but it can happen on the whole plant.

How do you treat yellow spots on leaves?

Also, why are my petunia leaves turning yellow?
You can do that, but you need to control their pollination to stop this from happening. To prevent this, cut the tips off each flower if a single one has turned yellow to prevent anthers from falling. However, if yellowing is only within a couple of flowers, and the leaves, stems and even roots are all unaffected, you only need to cut a few flowers.
How do you keep petunias blooming?
Feed the flower stems with a liquid fertilizer with a pH 4.5 to 5.5. (This prevents the plant from growing taller and flowering in the wrong season.) A petunia fertilizer and a good rain shower are all it takes to keep your petunia blooming all summer long.
What happens if you don’t deadhead petunias?

Why have my petunias gone leggy?
Stressful environment or conditions. For example, if your petunias have been in the shade, your plants may try to “steal the sun from the neighbors” by growing too tall.
