What is the problem with ligustrum?
Ligustrum has several problems. Cercospora leaf spot frequently infects it but in many cases does not necessitate its treatment. Botryosphaeria is a disease for which there is no treatment and often requires the removal of parts of the affected plant. A less frequent problem is caterpil- lar infested plants. Ligustrum is a tough plant and hard to kill. But it cannot survive prolonged wetness in the soil. Some of the areas you have are lower and have poorer drainage, which provides the perfect conditions for root rot.Wax Leaf Ligustrum is susceptible to several diseases that can hinder flower development. Fungal infections like powdery mildew and bacterial blight are among the most common.Fertilizing Wavy Leaf Ligustrum (Ligustrum japonicum ‘Recurvifolium’) helps promote dense foliage, vigorous growth, and a healthy root system—especially in the early stages of establishment. Apply a balanced, slow-release fertilizer such as 10-10-10 or 12-6-6 in early spring, just as new growth begins.
Why is my ligustrum dying?
Ligustrum is a tough plant and hard to kill. But it cannot survive prolonged wetness in the soil. Some of the areas you have are lower and have poorer drainage, which provides the perfect conditions for root rot. In very hot conditions (30’c+) Ligustrum can close down and stop growing. Watering – During summer (growing season) it is important to ensure that the plants do not dry out. Watering should take place every day, preferably during the evening and care should be taken to avoid wetting the leaves.For the next four to six weeks, water at the rate of two to three thorough waterings per week. Fertilizing: Ligustrum should be fertilized at least two to three times during the growing season. Use Espoma Plant-tone in early spring, and then several times during the summer and early fall.How often should I water Sunshine Ligustrum? Water regularly upon initial planting. A deep watering once a week is sufficient until established. Once mature, it becomes drought-tolerant.Ligustrum can be grown in full sun or part shade. A minimum of 4 to 5 hours of direct sunlight is recommended for best foliage density and flowering. Start by digging your planting hole at least two to three times as wide and no deeper than the rootball of your Ligustrum plant. The wider the hole the better.
How do you maintain Ligustrum?
Prune Ligustrum plants during late winter or early spring, before new growth. This allows time for regrowth to become established before the next growing season. Light pruning can take place in late summer if necessary, but avoid heavy pruning that will cause stress to the plant going into winter. Fertilizing: Ligustrum should be fertilized at least two to three times during the growing season. Use Espoma Plant-tone in early spring, and then several times during the summer and early fall. Apply 1/2 to 1 cup of fertilizer to each plant, distributing lightly over the entire root zone.
What are the cons of ligustrum?

Apply fertiliser in spring and optionally again in summer.Miracle-Gro Water Soluble Lawn Food could be used on privet hedges, but it is not the best option. Privet hedges prefer a fertilizer that is high in nitrogen and phosphorus, while Miracle-Gro Water Soluble Lawn Food is a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium.The most common pests that affect privet hedging in the UK include vine weevil, spider mites and scale insects. Common privet hedge diseases should be dealt with quickly to prevent your privet hedge dying, these include honey fungus, powdery mildew, rust and leaf spot which are common in UK gardens.
