Sunshine Ligustrum Plant

1. Under and Over Watering

Watering a plant is very important. But you have to determine how much water the specific plant requires. Both sufficient and insufficient watering can stop the growth of your Sunshine Ligustrum.

If the plant remains underwatered for days, then it will start dropping leaves by making them wilted. Soon, it will also stunt growing leaves or brunches.

Generally, Sunshine Ligustrum requires a lot of water for thriving well. Again, summer is the season when the growth rate of the plant remains at its peak. So, it requires more water in summer for growing along with photosynthesizing.

Therefore, it is very important to keep the shrubs hydrated throughout the whole summer. Then again, too much watering can be detrimental as well. All plants are choosy about the amount of water they will be taking.

Sunshine Ligustrum is not exceptional. Thus, constant watering and wetness can slowly kill the plant instead of helping it to grow. Hence, it is very important to water the Sunshine Ligustrum properly.

Signs

For underwatering

  • Wilting of leaves
  • Leaf droppings
  • Dead leaf tips
  • Dry soil

If you live in an area where the rainfall is low and the climate is arid then you might have to water the Sunshine Ligustrum twice a week.

2. Pest Attacks

Pests are very common in Sunshine Ligustrum. But if you allow them to reign then you might have to regret it later since these pests stop the growth of the shrubs. Pests that are most likely to attack the Ligustrum plants are aphids, weevils, and scale insects.

Pest Attack on Sunshine Ligustrum

Sunshine Ligustrum hedge can be highly attacked by aphids at times. Sucking the cell sap from both young and old leaves, the bugs do not allow to grow the plant anymore. Also, they weaken the internal metabolism of the plant.

 Like aphids, vine weevils also cause the same to the plant. These beetles are way dangerous. They cause holes in the leaves and stems and make these parts their source of food. These vine weevils mainly remain in the soil and eat up soft and young stems and leaves.

Consequently, the golden hedge stops growing. In summer, these vine weevils can

Now, talking about the scale insects, these are also sap-sucking bugs. Creating smaller bumps on stems and both sides of the Ligustrum leaf surface, these bugs destroy the entire hedge.

Signs

  • Aphids cover the entire leaf
  • Eat up entire leaves
  • Scale insects create shells
  • Destroying of stem
  • Growth stunt

Control Measure

  • Use or call for beneficial insects for eating up the pests.
  • To remove aphids, use a damp cloth to wipe off the pests from the leaves.

Thus, choose the pesticide according to the pests that have attacked your Sunshine Ligustrum hedge. However, keep in mind that the best time for applying pesticides is summer.

3. Cold Weather and Temperature Fluctuations

Sunshine Ligustrum also stops growing in extremely cold weather. This kind of weather causes leaf drops and eventually, the plant stops growing new leaves or branches. This weather also makes the leaves brown and wilted.  

Again, extreme cold weather also invites winter mold caterpillars. These caterpillars attack the Sunshine Ligustrum hedge and make holes in new leaves. These small holes are quite visible and are the main reason for not growing the sunshine Ligustrum anymore.

Honey fungus can kill the roots of the plant hence, all metabolic activity and nutrient transfer get stopped. Leaves also become pale or brown.

So, eventually, the plant also stops making food and growing. Then again, if the fungus gets favorable conditions like humid weather, then the branches also die slowly.

Moreover, you might also see powdery mildew over the leaf surface of the Sunshine Ligustrum. It is also a fungal disease and it is common for this plant. Powdery mildew covers the entire surface of the leaves and helps in distorting the growth of your plant.

Therefore, there is no chance the Ligustrum can further grow any new tissues or young leaves. However, powdery mildew takes place when the leaves of the plant remain wet for a longer time. This condition is favorable for them.

Signs

  • Deformed leaf and stem
  • Turning leaves yellow and pale
  • Rotting of root
  • Poor development
  • Stunted growth

Moreover, the plants thrive well in moderately acidic to moderately alkaline soil. Too much acidic or too much alkaline soil will not work for the plant. Hence, the Sunshine Ligustrum will not grow properly.

Signs

  • No growth of the plant
  • No young leaves
  • Leaf drops
  • Wilting

Control Measure

  • Plant the hedge where it will get at least six hours of direct sunlight.
  • Transplant the Sunshine Ligustrum where the light is too much or too less.
  • Mulch the soil before planting the shrub to have full growth.
  • Amend the soil before planting if it is too acidic or too alkaline.
