Persian lilac

When it comes to watering Persian lilac, this plant must be kept evenly moist. Make sure to water the plant once every week, making sure the soil is moist but not soggy. In periods of hot weather, you may need to water the plant more frequently to keep the soil moist. During periods of cooler weather, you can reduce watering to once every 2 weeks. Although it is important to keep the soil moist, overwatering can be detrimental and may cause root rot. Make sure the soil can drain freely and avoid pools of water around the plant's roots. If you are unsure, use your finger to check the moisture content of the soil, if it is dry 1 inch down, then it is time to water.

Persian lilacs require at least 6 hours of direct sunlight per day. Morning sun is especially beneficial for healthy blooms and foliage growth. If possible, it is best to have some dappled shade during the hottest parts of the day, as the intense afternoon sunlight may cause discoloration of the leaves. To ensure that the Persian lilac is getting adequate sunlight, it needs to be planted in an area that receives direct sunlight from early morning until late afternoon, with some protection from the harshest part of the day.

The best time for pruning Persian lilac is in the late winter or early spring before the new growth emerges. Prune only to reduce the size and shape of the shrub, removing no more than 1-third of the total amount of foliage. Any more than that could result in shock and the potential loss of flowers or foliage. If multiple prunings are needed in a season, spread them out over several weeks to allow the shrub time to recover.
