Some common causes for which your Gardenia plant is wilting

The most common cause behind the wilting of Gardenia is root rotting. When the soil gets too soggy, the roots of the plants get infected and start to rot, causing the entire plant to wilt.

Gardenias are irresistible to heat and overwatering can cause them a lot of damage. General symptoms like yellowing of leaves or wilting of leaves indicate rotted roots. Some of the common Gardenia problems that lead the plant to wilt are pest attack, insufficient lighting conditions, unsuitable water requirements, overfertilizing, etc.

Let’s dig into the topic deeper,

Overwatering

Overwatering is the most common reason that leads Gardenias to wilt. If you notice drooping leaves or wilting in your Gardenia plant, this is the first thing that you should check for.

Avoid letting your Gardenia plants sit on soggy soil. When Gardenia roots are exposed to wet soils for a prolonged period, the risk of root rotting increases which further proves to be fatal for the health of the plant.

Once the root starts rotting the plant will not get enough moisture and nutrients for its survival and as a result, the plant will start to show symptoms like leaf wilting and leaf yellowing.

How do you know when your Gardenias are overwatered?

  • Initially, the older leaves towards the bottom of the plant will start turning yellow and, eventually, the entire foliage will turn yellow.
  • Despite the soil is damp, there will be widespread leaf drops. Yellowing and leaf drop are indications that there is a deficiency of various soil nutrients like nitrogen, zinc, and iron. Leaf drops can also refer to unbalanced soil pH.
  • If you notice that even after the growth of new leaves, the tips of the leaves turn brown, take immediate action as it is due to overwatering.
  • If there is a bud drop even after the fulfillment of optimum water, light, and temperature requirements, it might be due to rotted roots.
  • Lastly, when the plant finally wilts after giving all the hints, the possibility of root rotting due to soggy soil is obvious.

In the case of overwatering, Gardenias are plants that need a considerable amount of care and attention. Similar to overwatered Gardenias, underwater Gardenias also cause wilting.
