∙ 11y agoBlooming requires a lot of energy from any plant, shrub, or tree. They need nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, copper, iron, manganese, molybdenum, and zinc. Nitrogen is the most important, followed by phosphorus and potassium. All growing things need nitrogen to both grow and to decay back into the soil. Perhaps fertilizer or richer soil amendment needs to be added, although lilac trees prefer neutral soil when it comes to acidity. Other factors are not enough sun, powder mildewing, poor drainage, and over-pruning. Buds for the following blooming season begin in early to mid-summer and need to over-winter, so it's important that they not be disturbed or damaged by the aforementioned conditions.
