How to Fix Star Jasmine Problems

Star jasmine is a staple ornamental plant because of its fragrance and beautiful flowers that add a touch of elegance to any garden. But it’s not perfect, as it’s susceptible to wilting, pests and diseases.

Fortunately, this article lists the most common star jasmine problems and teaches how to fix them. So, keep reading to learn how to solve these problems and keep your star jasmine plant happy and healthy.

1. Yellowing Leaves

Yellowing Leaves

How To Fix: Add nitrogen to the soil.

Star jasmine plants turn yellow because of a lack of chlorophyll, the green pigment that absorbs light energy and converts carbon dioxide and water to glucose and oxygen through photosynthesis. 

Lack of chlorophyll is usually caused by overwatering. When the plant gets drenched, it leads to root rot, damages the roots and causes the yellowing of leaves.

Yellowing leaves can also be the result of nitrogen deficiency. Nitrogen is essential in photosynthesis, so when it gets depleted in the soil, it causes leaves to turn yellow.

Solution: Add nitrogen to the soil.

Things You NeedNitrogen-rich fertilizer

Replenish the depleted nutrients by adding nitrogen-rich fertilizer to the soil. This will help boost chlorophyll production as well as other proteins which are essential for photosynthesis. 

When plants absorb more nitrogen and get to make their food, they grow faster and stronger, and their leaves turn back to green. 

2. Browning Flowers

How To Fix: 
Option 1: Water deeply and keep the soil moist.
Option 2: Spray neem oil solution on the plant.

Star jasmine flowers turn brown because of a lack of water or aphid attacks. 

When this plant doesn’t get enough water, especially during hot weather or summer, the dry soil damages its roots, leading to browning flowers. Aphids are tiny insects that suck the sap out of the plant. As a result, the plant weakens, and the flowers turn brown.

Option 1: Water deeply and keep the soil moist.

How To Fix: Correct the watering problem.

Leaf drops on star jasmine plants are commonly caused by overwatering or underwatering. If it sits on wet or dry roots than it can handle, its leaves will inevitably start to fall off.

When the plant sits on wet soil, the roots begin to drown and rot, unable to transport the needed nutrients to the plant. As a result, the leaves weaken and begin to drop. 

On the other hand, when there’s too little moisture, the star jasmine plant’s roots dry out and get stressed, and the leaves will also wilt and fall off the plant.

Solution: Correct the watering problem.

If your star jasmine plant is underwatered, water it deeply until it drains out of the bottom of the pot. If it’s overwatered, then allow the soil to dry out completely and only water when the top inch is dry to touch.

Location is another essential factor in fixing watering problems. For instance, if the star jasmine plant is in a container, make sure it has drainage holes to allow excess water to drain out and prevent the roots from waterlogging. 

If your star jasmine is in a garden bed or on the ground, keep the soil well-drained by adding sand or gravel to the soil.

4. No Flowers

How To Fix: Apply phosphorus-rich fertilizer in the soil.

Star jasmines fail to bloom when they don’t get enough fertilizers or absorb too much nitrogen from the soil.

This plant needs nutrients to grow and flower, and fertilizers help boost its development in every planting stage. When the plant doesn’t get enough fertilizer, they do not have the adequate nutrients and energy to produce flowers. 

Too much nitrogen also prevents star jasmines from flowering. Nitrogen is a major nutrient in the growth of a plant’s leaves and stems, but in excess, their growth will be at the expense of flowers.

Solution: Apply phosphorus-rich fertilizer in the soil.
