Are sunshine ligustrum as prone to pest and disease as all other ligustrum.
Different web sites tell different things, so not sure what to think.
No, this is a very hardy and easy to maintain shrub.
This plant does best in full sun, which means at least 6 hours of sunlight a day. You need to plant in well-drained soil, as privet cannot tolerate soggy feet. The bush can adapt to most well drained soils. Water frequently to help the plant get established. After that the plant is quite drought and heat tolerant. We recommend adding mulch to the base of the shrub to help maintain moisture to the soil, and help protect shallow roots from harsh weather conditions. You can prune Sunshine Ligustrum almost any time of the year. Although pruning is not needed, as the shrub has a clean shape and does not grow past 6 feet tall. Do not prune close to the first frost of the year. Trim any dead or sick branches throughout the year as necessary. Fertilize in early spring using a slow release formula. But fertilizing is not typically needed, unless you have poor soil conditions.
